The trimmer for the grass does not start hot
Trammer for grass, both electric and with an internal combustion engine (ICE), is an indispensable tool in the summer and autumn period for owners of cottages and private houses.
With its help, weeds, small shrubs are easily removed and the lawn is trimmed. But, like any technique, trimmers for grass fail at the most inopportune moment.
To eliminate the malfunctions with your own hands, the user of this technique first needs to determine the reason for their appearance.
The main malfunctions of gasoline and electric trimmers
In the lawn mower and an electric trimmer for grass, if you do not consider breakdowns associated with the bar and the mowing head, the malfunctions mainly happen in the engine area.
Damage of gasoline trimmers
Typical breakdowns of a gasoline trimmer for grass, which are most often faced with the owners of this unit, are as follows:
- engine breakdown;
- problems with the carburetor;
- problems with the supply of fuel;
- muffler malfunction;
- gearal breakdown;
- The starter broke;
- Air filter problems;
- Broken a buckshot on a gas tank.
Malfunctions of electric trimmers
Since the device of an electric coser is much easier than a motirmer, then there are few reasons for its failure.
It should be noted that the elimination of some of them is best entrusted to the specialist.
Basically, the trimmer for the grass ceases to work normally in the following cases:
- Electric cable malfunction;
- The control button is faulty;
- burned engine winding;
- Contact joints break on the engine.
Why is the gasoline trimmer not starting for the grass
The reasons why the gasoline trimmer for the grass stopped starting is different, therefore, a phased diagnosis of the apparatus is required.
Fuel tank (fuel quality)
Remember that always before starting the unit, a check of the presence and quality of fuel is required. In this case, you should not be greedy and save, as well as “clever” about the amount of oil added. Everything must be done according to the management attached to the apparatus, since when the piston group fails, its replacement will cost about 70% of the total cost of the trimmer for the grass.
Pour fuel due to the fact that you will fully conside it when performing work. After a while, the gasoline remaining in the tank loses its properties and can harm the engine. Therefore, do not prepare the mixture for the future and in large quantities. If the lawn mower starts poorly, try to drain the “old” fuel from the tank, and season it with a freshly prepared mixture.
Important! To refuel the device with fuel, the origin of which is unknown, fraught with negative consequences. Gasoline should be of high quality, bought at a gas station, and its brand should be not lower than AI-95.
Candle and candle channel
So, you changed the fuel, but nothing has changed, and the trimmer for the grass still does not start. In this case, it is worth checking the candle channel: whether it throws it with a combustible mixture.
Often users transfer the air damper to the “OFF” position when starting, and when the engine started, they do not transfer it to the “ON” position, after which it stalls.
Further, an attempt to start the internal combustion engine to again leads to the fact that it floods the candle with gasoline, and the start becomes impossible. To diagnose and eliminate the possible problem in this node, do the following.
- It is necessary to unscrew the spark plug, wipe it well and dry it. When installing a candle in the ICE cylinder, it should be dry.
- Draw from the combustion chamber the fuel accumulated there. This is done through the hole from which you twisted the candle.
- In the presence of soot on the electrodes of the candle, it must be removed either with a thin file or a nail file.
- Do not forget to put the gap between its electrodes before installing the parts in place. The gap on the candle should be 1 mm. As a probe to check the gap, you can use a coin.
- Next, collect the block, read the start instructions and try to start the engine again.
If the engine does not start, then you will need to check the spark. For this:
- unscrew the candle;
- put on it a cap of a high.voltage wire;
- Touch its metal part to the cylinder body (to provide contact, you can insert a tubular key) as shown in the figure below;
- pull the launch cord so that several engine speeds occur.
Normally, with each piston roll between the electrodes, the candle should slip a spark. If there is a spark, then the reason that the internal combustion engine is not launched should be sought in other nodes of the device.
For a better understanding of the process, how to test the candle for the presence of a spark, you can use this video where the check is shown by the example of the Lawn Mushiel “Soyuz”.
If there is no spark, then in the beginning check the cable connecting the candle to the coil. perhaps the reason is in it. You can call it with a tester. In case of detection of the rupture of the chain, a high.voltage wire will require a replacement.
Also the reason that the spark has disappeared is a malfunction of the ignition coil (magneto). The figure below shows what the coil (magneto) looks like from the gasoline trimmer for Patriot grass (Patriot).
To exclude the malfunction, it will be necessary to use a tester to check the Magneto trimmer for the grass, namely, its primary and secondary winding. On the primary winding, the resistance should be in the range from 0.4 to 2.0 Ohms.
If the device shows 0. this means that there is a short circuit in the winding, and if infinity is a clear sign of a chain break. The resistance on the secondary winding should be in the range from 6 to 8 kOhm.
On some coils, it can reach the value of 15 kOhm.
If your lawn mower does not start well or stalls immediately after starting, you should pay attention to the air filter, since it can be clogged, as a result of which the air does not enter the combustion chamber, and fuel ignition does not occur.
To check if the filter is the case, remove it and try to start the engine. If he earned, then the reason was found. The filter needs to be replaced or rinse well and dry before installation.
Trammers’ speeds fall. Why stalls a gasoline trimmer for grass
A braid braid with a gasoline drive is a useful thing for owners of personal plots, lawns, and when a trimmer for grass suddenly stalls, the work on cleaning the territory stops from the grass. The device itself is a rather complex mechanism, so there are many different causes of its breakdowns. The most common problems contain instructions for operating. Know the reasons why the trimmer stalls for the grass, it follows to independently effectively perform the repair of the device. Malfunctions with a benzocosa associated with the fact that this device is not started, in a certain way are classified by specialists of service services. They stand out malfunctions with the following nodes of the mechanism:
- the engine in which the piston and bearings can be worn out or fail to crack the crankcase;
- the fuel supply system, while it is possible to clog the filter or problems with the carburetor;
- mechanical damage to wires, tubes, hoses;
- The ignition chain.
To correctly determine the knot where the breakdown occurred, it is necessary to pay attention to the circumstances of the trimmer stalls for the grass.
Where to start diagnostics motorcycles
If the lawn mower does not start or immediately stalls after starting, it is necessary to sequentially check all the main nodes and assemblies. The test algorithm is as follows:
- Fuel tank (fuel quality);
- Candle and candle channel;
- Air filter;
- Fuel filter;
- Graduation channel.
These nodes are most often source of basic problems, which can be eliminated after a thorough inspection.
Check the fuel mixture
Before starting the engine of a gasoline braid for grass, check the presence, and the quality of the fuel mixture. Do not save, do not greedy and “do not smarter” in this matter. The best light gasoline trimmer for grass
Repair or replacement of the piston group will cost you too much (sometimes up to 70% of the cost of a new tool). Prepare the oil fuel mixture strictly according to the instructions. Calculate its number from real needs. Excess gasoline left after work loses its qualities over time.
We diagnose a candle and candle canal
If the quality of the fuel mixture is not in doubt, and the lawn mower stalls when starting, then a flooded candle may be the reason. Here, a regular candle key is suitable for repair (every motorist has probably has a spare candle.
- We twist the candle and wipe;
- We thoroughly dry it (you should not bake it);
- Excess fuel in the chamber we drain through the candle hole and dry it;
- We clean the old candle from the carbon on a sugar or a ladies’ file;
- We set a gap with a distance of 1 mm (you can check with any coin);
- We return everything to place and try to start a trimmer for the grass.
Dry the channel at least 30-40 minutes. Otherwise, there is a risk of re.pour a new candle.
If the working candle is working, the nest, where it is located completely dry, and the lawn mower does not want to start, lubricate the threaded connection with gasoline. It should be slightly moisturized. No matter what wonderful spark gives out a candle, there is simply nothing to light up in a dry chamber.
If the trimmer engine for grass still does not start, such a cause as the lack of spark due to weak contact between candles and a high-voltage wire should be excluded. Lawn mowing trimmer for grass review comparison. If the connection is of high quality, and there are no sparks, most likely, you have “flew” the ignition unit. Here you can’t do without a master, t. to. The part is not repaired, but sold by a whole knot.

Diagnosis of the filters of the lawn mower
Another reason why the gasoline braid for grass stalls is an air filter. To exclude it, try to remove the filter and start a trimmer for grass without it. If it turns out, then you will have to change the air filter to a new one, or at least blow and carefully clean the old.
You can’t start a gasoline trimmer for grass due to contamination of the fuel filter. This is the next stage of our algorithm. Here we check the state of the filter element and, if necessary, change it with the new. When replacing, try not to leave a suction pipe without a filter, this is prohibited by any operating instructions. A braid for grass for grass gasoline

Often, “delicate” branded models of benzos are not launched and stall due. The main function of this element is to align the pressure in the gas tank. When clogging this node, a vacuum is created in the tank that prevents the supply of fuel. Eliminate the malfunction can be cleaned by cleaning the sounds. A trimmer does not start for Huter grass. You can use a regular needle for cleaning.

Cycle: what mistakes of beginners lead to breakdown of the engine of the trimmer for grass and exclude its normal operation
6 common mistakes with fuel
The manufacturer in the instructions clearly indicates the brand of gasoline with an octane number, oil and their proportions.
The first three errors are that the user of motorcycles violates all or one of these requirements. The motor will most likely start and work, but its resource may decrease sharply.
A small amount of oil, like its absence, will lead to the fact that the walls of the cylinder will not grease normally, and the piston rings will scratch them, and not slide.
Excess oil will simply burn, forming soot. She will pollute everything, including the piston and cylinder.
Failure gets into the valve, blocks their work, after which the motor will not start.
Will have to disassemble and clean the carburetor, or even put a new. Of course, you can try to wash the piston and the cylinder: it may be possible to bring them into working condition, but it is better not to bring them to.
The fuel mixture must be prepared with high quality and in strict proportion. The repair of a spoiled engine is expensive, about 70% of the price for a new gasoline trimmer for grass.
For the preparation of high.quality fuel mixture, I have a special container with a factory division of divisions in a set of trimmer for grass. Gasoline is neatly poured into it to the level of 500 ml, and then the oil to the required label.
An alternative method is the preparation of a fuel mixture with filling gasoline into a calibrated container, for example, a liter canister or a plastic bottle to a label, and an oil additive with a medical syringe according to its divisions.
The dosage with a syringe is more convenient, is considered the most popular way.
I recommend filling gasoline through a funnel with a narrow neck that has a filter: a metal mesh. protection against small garbage.
The prepared mixture should be well shaken and mixed until a uniform color appears. Only after that it can be poured into the tank.
If the mixture does not blame, then it will remain in the tank, and through the carburetor will enter the combustion chamber in portions with different ratios of gasoline and oil.
Fractions of clots of oil clog a candle. The motor stops, stalls, does not start. This is the fourth mistake of beginners.
It should be borne in mind that gasoline is hazardous. The risk of fire exists. Therefore, it is necessary to fill the mixture at a safe distance from the buildings, and in the case of the strait, which often happens to eliminate the causes of a possible fire. Violation of fire fighting measures. error
After pouring the fuel into the gas tank, the latter closes with a screw plug and the lack of leaks is checked. The trimmer for the grass is raised up so that the gasoline fills the cork. There should be no subterations from under the lid or from the fuel hoses.
Lack of such a check. an error can cause a fire.
There is one technical cunning that can cause a benzotrimer motor is not started due to the cessation of fuel supply. If you look carefully at the center of the traffic jam, then a round hole is clearly visible.
We turned Motokosa. Gasoline filled the cork, but does not flow through the hole: there is a sapphone inside. He is working.
On the inside, its design is clearly visible: a valve system of plastic and rubber is built.
In the usual state, the valve is pressed to the hole and the fuel does not flow. Когда бензомотор работает, то топливная смесь расходуется через карбюратор. A vacuum is created in the tank. The vacuum opens the valve of the saapon, the pressure is restored.
You should know the two consequences of a malfunction of the sapuna:
- Constantly open hole. fuel pours out of the tank during its inclinations (excess consumption and the probability of fire).
- Contamination or sticking of the valve channel is the reason that the lawn mower does not start or stalls.
Check the soundtress is easy: you need to blow it in both directions.
All about the gas tank cover, including the repair of the saapun, is shown in the video of Bogdan Shabanov.
3 additional advice associated with limited chemical resistance of a mixture of gasoline with oil:
- Do not create an excessive fuel supply. Use freshly prepared fuel mixture. In a maximum of a couple of weeks, she will lose her useful qualities;
- Prepare as much fuel as it will go to one mowing during the day. At the end of the work, drain the rest from the gas tank and burn the last drops from the fuel canal with a neglected engine;
- It is especially dangerous to leave the mixture in the gas tank for a long time. winter. In the spring, you will make sure that the engine does not start without cleaning the carburetor (gasoline evaporated, the oil thickened and glued the valve).
In more detail, the technology for eliminating these malfunctions shows in its video video “Chinese lawn mower is not started” Sergey Lesnik. Pay attention to the fuel filter.
To adjust the work of the carburetor allows a special screw, but it is not worth it to twist it without need: the factory adjustment is accurately exhibited. It is better for novice users to contact the service center.
Cycle: why the piston may not move inside the cylinder
The flywheel of a trimmer for grass, aka Magneto’s rotor with magnets, is fixed on the shaft with a key.
This is usually a reliable connection. Under the flywheel there is a sealing oil seal that does not pass the oil from the crankcase out. But when he wears out, the craftsmen have to remove the flywheel and change the oil seal with a new.
Otherwise, the oil flies everything, including the air filter.
At the same time, it is not so easy to remove the key: people make special pullers.
When looking for information on trimmers, I came across a video of one master, who was brought into the repair of the lawn mower, where the flywheel gap was absent. Perhaps a factory marriage. Naturally, such a motor will not start.
A similar reason should also be borne in mind.
Hitachi gasolimmer stalls and does not start
The gasoline trimmer for grass (sometimes the device is also called a gas station, motorcycle system) can fail for various reasons, for example, after the winter, if it is not for a long time. RIA Novosti, 29.09.2022
29 Sep. RIA Novosti. The gasoline trimmer for grass (sometimes the device is also called a gas station, a motorcycle system) can fail for various reasons, for example, after the winter, if it is not used for a long time. What to do if the trimmer does not start for the grass or stalls almost immediately after the launch, why the spark disappears in it, possible causes of malfunctions and ways to eliminate them. In the material of RIA Novosti.Trammers do not start with the help of a modern tool for mowing grass, you can quickly put the cottage and adjoining section in order. Trimmer for grass will help to carefully mow vegetation even in conditions of uneven relief. Such devices weigh relatively few, so their use and, if necessary, transportation will not be difficult. Depending on power, they can cope not only with grass, but also with shrubs.There are various types of trimmers to work on the site. Most often, the owners of country houses and cottages have to choose between gasoline and electric tools (the latter, in turn, are divided into those that work from the network and the battery). Each of these types has its advantages and disadvantages, and the final choice largely depends on what tasks will have to be solved with the help of the instrument to its owner.Many prefer gasoline trimmers. Then we will talk about possible malfunctions precisely in this version of the tool. As a rule, for regular mowing of the adjoining section, the power of a two.stroke engine will be enough.The causes of problems with launching breakdown a person risks colliding after the tool has not been used for a long time, for example, after storage during the winter months.To launch a trimmer for grass, it is necessary to carry out a number of manipulations, the rules of execution and the sequence of which are registered in the instructions for the tool. However, sometimes, even if the owner does everything right, the trimmer for the grass suddenly refuses to start up. The reasons for this can be very different: from the quality or shelf life of fuel to a malfunction of one or more parts in the engine.If there is no way to quickly give a trimmer for grass for repair, you can try to determine the cause of the malfunction yourself by checking the tool for the most common sources of problems.The engine malfunction to identify the cause of the problems that have arisen, the owner of the trimmer for the grass should check one after another check the key details of the engine of his tool. In many cases, you can determine the source of malfunctions yourself, without turning to the help of specialists.The malfunction of the hopper to verify the main nodes of the trimmer for the grass in search of possible causes of malfunctions, it is worth paying attention to the sapun. valve that helps to level the pressure in the engine. In fact, he passes the air necessary for its proper operation to the gas tank.Make sure that this detail was the cause of the malfunction, you can simple manipulations. To do this, it is enough to open the gas tank cover: if at the same time a characteristic sound is heard from a sharp absorption inside the air, it means that it is a saepun to suspect of problems with the launch of a trimmer for grass. By the way, this part can be carefully cleaned and returned to the place or replaced.Prisyl’s malfunction trimmer for grass refuses to start, pay attention to the state of the primer. The function of this part. Forced pumping fuel into the carburetor of the tool to quickly start a trimmer for grass with a cooled engine. It is a special button on the case, which must be pressed at the start of the launch.The idea that the root of the problem lies precisely in the work of the primer, the owner of the trimmer for the grass should lead to the fact that even after numerous attempts to launch the engine “on the cold”, a positive result can be achieved with great difficulty.Carburetan malfunction malfunction of the carburetor in the trimmer can hint several “symptoms” at once. For example, the engine is very difficult to start both in the “cold” and in a “hot” state or with great difficulty gaining the necessary speeds. At the same time, the carburetor will not necessarily be faulty; Perhaps it just needs to be adjusted.In order to determine what exactly caused the problems in the carburetor, it, as a rule, must be disassembled. However, this is not recommended to do this without the necessary knowledge and skills.A fault of the air damner drive is poorly started by a trimmer for grass with an unheated motor, the cause of the malfunction can lie in the improper operation of the air damper. If this part is faulty, then the engine can still be launched, however, at the same time, the transfer of the lever of the damper to the desired position does not give the expected effect.The function of such a damper. block the air supply at the right time, but if it holds well, the tool will not work properly. In this case, a faulty part will have to be replaced.Failure of the ignition system rule rule. Trimmeres ignition system includes three elements. The first (and main). This is the ignition coil. It consists of a core and several windings. The second element. This is the so.called flywheel on which several magnets are located. Third. The sparkling candle on which the necessary spark is formed in order to ignite the fuel.One of the most common malfunctions, due to which a trimmer for grass refuses to join in the work. This is a violation in the parameters of the gap between the magnets and the ignition coil. The indicator of 0.2 mm is considered optimal. For various reasons, this distance can increase, but the energy of the resulting spark, on the contrary, is noticeably reduced.The malfunction of the ignition coil itself can also lead to problems. You can check its performance in several ways, for example, by measuring the resistance indicators on it.Another source of possible malfunction may be the spark plug installed in the trimmer. You can evaluate the condition of such a candle without additional equipment, just twist it and carefully inspect the appearance and integrity of its contacts. The detail that was in the work is allowed by the appearance of a raid, but if it is black or white. So, the candle is not fully working. You need to check the gap of the candle, on average it should be 1 mm.The presence of problems may also indicate the fact that the candle was unscrewed from the ignition system turned out to be wet. In this case, the candle must first be dried in any permissible way and only then check whether it works or not.The quality is fuel that is worth doing if the trimmer for the grass for unknown reasons refuses to start. This is to check if there is a fuel in the gas tank. However, even if there is gasoline in the tank (provided that everything is in order with the tightness of the equipment, this liquid evaporates very slowly), there is no guarantee. that after a long break, it will be suitable for work.It is also important to remember that each type of engine in such tools makes its requirements for the quality and composition of the fuel. For example, for two.stroke engines, a mixture of gasoline and oil is used in proportions established by the manufacturer.In this case, in order to establish the work of the tool, low.quality fuel must be drained and replaced with fresh.Violation of the engine start.up procedure, despite the fact that the appropriate operating instructions should be attached to each device, many new trimmers new owners prefer to understand the principles of their work on their own, without printed “hints”. And sometimes make mistakes, because of which it is not possible to start the engine engine.Another no less likely option. After a long break in work, a person can simply forget the right procedure for the engine starting. So if there is a suspicion that the cause of the trimmer’s malfunction lies in this particular, it is worth it to re.read the instructions (or read it for the first time).A short circuit wire problems with the launch of a trimmer engine for grass may consist of faulty wiring. In the process of the tool or due to the low quality of the material that is used to isolate the wires, there may be a closure. Return the tool to work should help replace damaged sections of wires.Zasori in the air filter in the problems of a trimmer for grass can lead a blockage formed in an air filter. This may indicate a black plaque formed on the spark plug. However, even with a clogged filter, a trimmer for grass is often launched, but the tool can not fully work in such conditions and stalls quickly, and also noticeably loses in performance.You can make sure that the root of the problem lies in the air filter malfunction, if you try to launch a trimmer for grass without this filter (however, you should not operate the tool for a long time). If the naked eye shows that the filter clearly needs cleaning, the necessary manipulations must be carried out in accordance with the instructions attached to the tool. And if the filter change has not been made for a very long time, the part can simply be replaced.In the fuel filters, not only the air, but also the fuel filter of the grass trimmer, which is responsible for ensuring that a mixture of oil and gasoline is entered into the carburetor, can not only be a air filter. Trimmerers may face such a problem, who are not used to refuel the tool not very high.quality fuel or gasoline remained in the tank for a long time.Sometimes, even with such a problem, the engine of the lawn mower still starts, but it does not work for long and quickly stalls. If, after checking the condition of the filter, it turned out that it is clogged with dirt, the owner of the trimmer for the grass needs to think about its replacement.Violation of the tightness of the fuel hose is that the tightness of the fuel hoses is disturbed in the trimmer, a strong smell of gasoline that appears after the launch of the tool may indicate. If the appearance of these tubes clearly leaves much to be desired or, for example, they are too easily, almost without effort are disconnected from the primer, then they most likely require replacement.Diagnosis of a malfunction in the trimmer is far from always possible to determine at first glance. Sometimes in order to find source of the problem, it is necessary to conduct a thorough diagnosis. Here are some of the situations that the owners of the trimmer for the grass most often risk faced, and those reasons that theoretically can lead to them.It does not start “on a hot” obstacle in order to start a trimmer for grass with a warmed engine, a variety of circumstances can serve. For example, a filter clogged with dirt, clogged ventilation holes or a malfunction associated with the ignition coil. It is these elements in such a situation that must be checked first.It does not start “on a cold” wrong gap between the coil and the flywheel can also lead to the fact that the owner of the trimmer for the grass will encounter problems and when trying to start the engine “for cold”. In addition, it makes sense to check the air damper, primer or sapun.A similar problem can also arise if in the engine of the trimmer for grass insufficient compression.One fairly common situation is poor. Regardless of whether the engine warms up or not before starting, a trimmer is started for grass poorly or not starting at all. The cause of this situation can vary from poor quality of gasoline or its insufficient amount to a malfunction of a candle, a saopon or other details.The trimmer engine starts up and stalls immediately, but almost immediately, despite the efforts of the owner, begins to stall, the fuel that is in the gas tank should be the first to come under suspicion. Perhaps it is no longer suitable for work tools and requires replacement.A similar problem can also be provoked by a contaminated saopan or fuel filter, which also makes sense to check.There is a spark, and a candle of instruments can also encounter a situation with this situation: the engine of the lawn mower does not want to start, while the light of the ignition is dry (that is, excess fuel does not fall on it), and there is a spark on it. If this happens, you can check the integrity of the fuel hoses, as well as the serviceability of the filters and the carburetor.There is a spark, and the candle was spinning a similar situation, but provided that the spark plug suddenly turned out to be wet, the first thing that should come to the mind to the owner of the instrument. For some reason, a trimmer for the grass is too much gasoline or, conversely, in the combustion chamber. Too little air. The clogged filter, a malfunction of the air barrier or other elements of a trimmer for grass may be to blame for this.If a person does not have the opportunity to check the presence of a spark, then the reason is also to look for the problem in the possible malfunction of the candle itself. First of all, it needs to be dried. so that you can evaluate the visual state, and if there are doubts about its performance. replace.There is no spark of spark. The occasion to check the condition of the wires in the tool: it is possible that there was a closing and a button that turns on and off the trimmer for the grass simply does not work. Another possible reason for the lack of spark. This is a malfunction of the candle itself on which the spark should appear (for example, the gap has increased) or problems with the ignition unit.The rules for storage of trimmermarous Trimmer owners are faced with problems when starting after long.term storage of the tool, including. After the trimmer for the grass returned from wintering. That is why it is so important to observe the rules for storing the tool.Rule 1. Be sure to save the trimmer engine for grass from all fuel remnants, and clean the tool and place the tool in a dry room.Rule 2. If before you remove the tool for long.term storage, the owner found defects or malfunctions in it, it is better not to postpone the repair until spring and put everything in order in advance so that the problem does not aggravate.Rules for operating a trimmer.forward by how to start working with a new tool, the owner should carefully study the instructions attached to him. After all, even if a person holds in his hands not the first trimmer for the grass with which he has to deal with, it cannot be ruled out that it is this tool that will have certain features that it is important to consider and observe in the process of launch, work and storage.Sometimes in attempts to save time on the gas station, the owner of the trimmer for the grass prepares a large volume of the fuel mixture for the tool in advance. It is important to consider that it is not recommended to store such a mixture for a long time, since its quality suffers during long.term storage. And this, in turn, can negatively affect the work of the tool. Prepare the fuel mixture in accordance with the instructions.While working with the trimmer, you need to ensure that it does not overheat much. If this happens regularly, the tool risks faster to fail. Do not wait for individual details of the trimmer for the grass to clog so much that they will stop his work. Periodically, the tool needs to be inspected and checked.Expertable advice if a person has enough technical information and understands the device of trimmers, benzos and other similar tools, it is still not recommended to disassemble certain details (all the more complex). In case of failure, this threatens a more serious breakdown of the tool, even if the malfunction was very insignificant.Many tool owners are worried about how to work correctly a trimmer correctly. “We support maximum turnover (that is, full gas) and in this mode Kosim, while there is a need and strength. Says Alexey Shikhov, head of the service department of the company “E. Kobert” at the same time, it is not necessary. With such work, the main thing. Less idle. The mixture burns out (oil and gasoline) when you give more gas, and at the same time the piston remains clean ”.
Why is a trimmer not starting for the grass: the main malfunctions and their elimination
As already noted, such situations are characteristic of trimmers who were inactive for a long period of time. Therefore, after detecting the problem, you need to immediately take up the search for a malfunction.
Fuel as source of problems
The first stage is checking the presence of fuel and its quality. First of all, they are convinced that there is a fuel in the tank. Those who have acquired the unit recently, often forget that the trimmer for the grass needs refueling. If there is no fuel, then the equipment simply cannot work.
If there is a fuel in the tank, but the trimmer does not start for the grass, then the owner needs to check whether he is acting correctly. In this case, it is recommended to study the instructions. If the launch is made correctly, then the malfunction can cause the inappropriate quality of the mixture.
- Oil. It should be special. intended for two.stroke engines. It is not recommended to save on the product, since the life of the equipment depends on the mixture. Trammers for grass with a four.stroke engine require pure gasoline, it is not mixed with butter.
- It is necessary to use not only high.quality gasoline, but also the brand that is recommended by the manufacturer of a particular model. If it is not possible to find out what fuel is necessary, then it is recommended to choose either AI-95 or AI-92, and the last gasoline is a favorite, since the first has additives that react with two-stroke oil. Other brands do not advise using.
- The correct preparation is shifted for a benzotrimer. It is noted that at first this stage is paid to maximum attention, but over time, kosari begin to mix the composition “by eye”, and this is already a serious mistake. The correct ratio of gasoline and oil is 25: 1. For a liter of the first, 40 ml of the second, two.stroke. Motor oil intended for a car is an inappropriate option, since at high temperatures the liquid loses (partially) lubricating properties.
The correct storage conditions of the fuel mixture are important. To save time, some owners prepare it for the future to use it in the coming weeks. This option is contraindicated, since the prepared fuel mixture quickly becomes unsuitable. The reason is the precipitation of oil loss. With this change, both oil products lose their properties. Even repeated stirring is not able to restore the initial quality of fuel. Therefore, they recommend preparing a certain volume: 2 liters, no more.
If everything is in order with gasoline and oil, then they start diagnostics. to check the spark plug.
Candle and its condition
At this stage of diagnosis, you need to stop in more detail. Most experienced owners who are already familiar with the question of why a trimmer for grass does not start, first of all check the state of contact contacts. Diagnosis of this element is carried out as follows:
- First, the spark plug is unscrewed, then inspect. If the electrodes are in perfect condition, then they should have a carpet whose color resembles a brick. Wet element, or white, black plaque on contacts indicates the presence of any malfunction. Pink and red electrodes. proof of a large number of additives in fuel. Such a mixture must be replaced.
- In the event that the spark plug is wet, this means that the combustion chamber has unbroken fuel. It is left in place. Candle contacts are cleaned, then dried (calcination is prohibited). After this stage, the candle is connected to the nurser.
- Then the ignition is turned on, the frontier handle is pulled. When everything is in order with the element, it must issue a constant spark. If it is weak or completely absent, then the verdict is one. you need to replace the spark plug.
There is another reason why a trimmer is not started for grass. This is a big gap that appeared between the contacts of the candle. A distance of 0.7-1 mm is considered normal. To correctly adjust the gap between the electrodes, use special probes.
If there is no such device, then the folk method is used. A razor blade breaks, folds its parts together. Then this “probe” is inserted between the contacts. Ideal. blades that enter tightly.
The problem is in the fuel and the carburetor
If there is a spark, and a trimmer for grass still does not show signs of life, then nuisance can lie in the fuel supply to the combustion chamber. To make sure that this node is to blame, they perform such actions:
- They are typed in a syringe or poured into a lid from a plastic bottle of about 20 ml of fuel.
- Then, through the candle hole, the fuel is neatly poured into the combustion chamber.
- The candle is returned to the place, put on the imminent, the engine is launched.
In the event that the trimmer has started for the grass, the problem may be in the fuel and carburetor. Когда эффекта от проделанных манипуляций нет, диагностику продолжают — проверяют высоковольтный провод. At the slightest suspicion, this consumption element is replaced by a new.
What to do if the engine is a trimmer for grass still refuses to work? In this difficult case, you can follow the following recommendations:
- In doubt about the candle and the high.voltage wire, it is better to immediately replace them.
- If, when checking the new sparkling candle, it was not possible to achieve a spark, then it is almost possible to say with complete confidence that the ignition unit is faulty. the coil came out of the system.
Check its serviceability simply: they twist the candle, then it is led to the trimmer body for grass. If there is no spark when the starter jerks, or it does not appear every time, then a new coil is required. This element can also be replaced independently.
How to avoid most problems?
The work of this seasonal equipment is very affected by its proper storage. over, this applies not only to a long “rest” in the winter, but also of short intervals of inaction. To protect yourself and the technique from problems, you need to adhere to a few simple recommendations.
- Before sending on a well.deserved rest, a tank trimmer for grass is freed from fuel remnants. To remove the entire mixture, the lawn mower is launched and allowed to work until the engine is stalled.
- The first operation after “winter hibernation”. pouring a small amount of oil into the candle hole. Before that, the piston is moved to the extreme position. Such a lubricant will facilitate the launch and prevent premature wear of the details.
Before starting working with a motorcycle, they must check the candle and all the main equipment components.
Reasons why the trimmer for grass does not start is quite a lot. But most of them can be detected and fixed independently. The main thing is the correct diagnosis, attentiveness and sequence of actions. And about how you can cope with problems, the master from the next will tell in detail
What is the resource of Chinese motorcycles?
Chinese or lawn mower is able to work about 500 mothers. But this is with the correct mixture, good oil, a good factory assembly. If a person fills gasoline with one good refueling, accurately measures the same oil along the Menzurka, the carburetor regulates the same mixture, the fuel burns correctly, then the coveted half a hundred hours of motor resources is a very affordable bar.
But here you can’t also forget about Chinese marriage. They even balance the shafts on their knee, put the cheapest bearings, carburetors stamp with clogged channels. If a person understands the principle of operation of a two.stroke engine and carburetor, understands how to sort it out, then he can eventually collect an almost perfect trimmer for grass.
In general, if we consider the Chinese motorcycle foam as a space for creativity, then even its breakdown is an occasion to study something new, this is a designer for a man.
If you need a tool, then it is worth finding a Japanese analogue, or switch to an electrical model.
Methods of elimination
Repair of a lawn mower is best started with a phased check of the main components. The first thing to check is fuel in the tank, as well as the presence of lubricants on the main nodes of the tool
It is also important to know what quality and what is the proportion of the fuel and oil used. If something is wrong, then the piston system may fail, and its replacement is expensive
Next, it is worth evaluating the serviceability and performance of the spark plugs. The result is evaluated by the presence of a spark when there is contact with the tool body. If the malfunction in the candle, then you need to remove the voltage wire from it.
In case of contamination, it is recommended to replace with a new one and drying the candle canal. This is also done if there are cracks or chips on the candle housing. The gap between the electrodes is set 0.6 millimeters. Squeezing a new candle is also produced by a special key. At the end, the voltage wire must be connected to it.
The inspection of filters, both fuel and air. If the blockages are strong, then the best solution will be their replacement. You can try the air filter with water with the addition of a detergent, and then dry. It is also sometimes soaked in gasoline
After drying and installation, it is important to moisten the filter with oil, which is used in the mixture with fuel
It is very easy to eliminate the problem in the form of a stalling lawn mowed immediately after starting. it is enough to adjust the carburetor according to the scheme given in the documentation. Sometimes you have to send the valves of the carburetor to facilitate the supply of the mixture in it.
Sometimes the lawn mower stalls due to the receipt of a large amount of air. In this case, it is necessary to increase engine speed to release it. It is also necessary to check the fuel hose for possible damage. If necessary, it is changed to a new.
It is important to maintain a gearbox clean, and its gears should always be treated with a special lubricant. It is worth noting that it is not always possible to repair a gearbox and starter on your own, therefore it is more advisable when breaking down these nodes to replace them with new
When reducing the engine power, it is worth paying attention to the exhaust muffler, or rather, to the net in it. She can clog because of soot from burned oil
This malfunction is solved cleaning the grid. You can do this using a small brush with wire or nylon bristles, as well as compressed air.
Clutch in benzocoses can break due to wear of the pads or a bursting spring. In both cases, the failed spare parts are replaced. Sometimes the clutch coupl is unusable, it can also be replaced with a new. over, on sale there are both couplings in full assembly and individual elements to them (washer, drum, etc. D.).
Common causes of breakdowns
First of all, it is worthwhile to verify the simplest things: the presence and quality of fuel, the correct order of action.
Use only those fuels and lubricants that the manufacturer recommends. Gasoline with too high octane number is sometimes no less harmful than the 80th. The instruction has not been preserved? Universal can be called AI.95 with a car gas station with a good reputation.
Pour only suitable engine oil. In the vast majority of gasoline trimmers, the engine is 2-stroke, so ordinary car oil cannot be used. For a 4-stroke engine, the oil is poured separately from the fuel. over, it is not worth pouring “working out”. used, used oil.
Remember, the repair of the piston group will cost 30. 70% of the cost of the new motorcycle. Savings on the quality of combustible materials is unlikely to cover these expenses
Exactly observe the proportions of mixing gasoline and engine oil, do not lie “by eye”. For most motos, a ratio of 1:25 is recommended, that is, 40 ml of oil per liter of gasoline.
Do not cook a lot of mixtures at once: ideally it needs to be developed in 1 day and store equipment with a dry tank. The maximum shelf life of the finished mixture is 2 weeks, so more than 2 liters at a time it makes sense to mix only to utilities who cut the city lawns.
If you have not used a scythe for a long time, and there is gasoline in it, it is better to pour it out. The mixture has already been divided into fractions and lost its properties, even the most thorough mixing will not save it.
After making sure that the gas tank is in order, try to get a braid. For this you need:
- Switch fuel into the carburetor with a grain button 5-6 times.
- Close the air damper.
- Turn on the ignition on the handle.
- Pull the starter’s cord 1-7 times, until the launch.
- In 5.10 seconds disconnect the start system.
After downtime, if you can’t start the engine in the usual order, try to open the throttle and press the gas trigger. Without releasing the trigger, pull the starter cord.
A fully working trimmer for grass is started 1-2 times, even if the cord is calmly pulled, and not pull it as much as possible
It is also recommended to start a motor with a clamped gas handle if it has not yet cooled after the previous working cycle.
If the engine has not started on 5-7 jerks, it is worth looking for a breakdown.
Option. a problem in the ignition system
The first thing that suspicious falls is. the candle does not give out a spark, and therefore the fuel mixture does not ignite. Most often the problem is in the candle itself.
For verification, unscrew the spark plug from the cylinder, having previously disconnected the wire from it.
The thin layer of brown soot indicates the normal operation of the engine, red or pink soil. an abundance of fuel additives, change the gas station. If the element is covered with black or white scale, the engine worked incorrectly.
Wet candle indicates overflow, excessive pumping of fuel with a primer. In this case, the candle needs to be dried, but not to get. Pour excess gasoline from the cylinder, turning the motorcycle.
When cleaning, pay the greatest attention to that part of the upper electrode that is aimed at central contact, but do not zeal too much
Contacts of the dried candle should be cleaned of soot with the help of a suprafil, sandpaper or ladies’ file. The gap between them should be 0.7. 1 mm. this is the thickness of the standard coin. If necessary, bent the upper electrode.
Before assembly, it is worth checking the performance of the candle. Connect it to the power (put on the cap), attach the body to the cylinder or any metal part of the engine, turn on the ignition, pull the starter. At the end, between the electrodes, with each jerk, a bright, powerful spark should slip through.
It is very important to observe safety precautions. There should not be a drop of gasoline on the neck of the candle opening and the body of the motorcycle!
If after drying, cleaning and setting a sparking gap, buy a new candle. It happens that the spark does not appear on the new candle. In this case, check the quality of the contacts, try to replace the armored vehicle. this is inexpensive and simply.
If there is no spark with a new wire, you need to buy a new ignition coil. It happens that the cable is not disconnected from the coil, they are sold only in the collection. It is somewhat more difficult to replace it on your own, because you need to accurately set a gap of 0.25. 0.4 mm to the stemstone flywheel.
The normal gap corresponds to the thickness of the plastic bottle (cut a piece of measurement from it) or 4-5 layers of painting tape
Install a coil with a spacer, try on. Twist the starter: it must touch the spacers, but completely turn. Remove paper tape or plastic and finally collect the knot.
It happens that when checking, the candle gives out a small but stable spark, but the launch does not occur. After you tighten the candle into the cylinder, in a closed space, a weak spark may disappear. In such a situation, it is also worth replacing the coil: the new one will give out a more powerful impulse.
Option. you need to replace the filters
If there is a spark, but the braid for the grass is not started, the problem is most likely in the fuel supply. The easiest way to check the air and fuel filter. with this and start.
Testing their condition is quite simple: remove the filter elements and try to start the motor. If it turned out, you need replacement or at least cleaning.
The fuel filter can clog so much that its body will not be visible. Naturally, attempts to clean in this case are useless
Other tool malfunctions
If all the problems described above are checked and eliminated, and the trimmer for the grass still does not start, probably problems with the engine itself. It may reduce compression due to the destruction of crankshaft oil seals or damage to the piston group.
This more often happens with trimmers that are used very actively or for a long time: for example, in utilities. To diagnose, use a compressometer.
The oil seal protruding from the crankcase is subject to replacement. it has already hardened, has lost its elasticity and cannot fully fulfill its function
In most cases, such a repair should be entrusted to the workshop, if only because in almost all trimmers for access to the oil seals and the cylinder, you need to unscrew the nuts with a thread fixer. You can do this either with an electroger.controlle, or warming them well.
The seals are located on both sides of the crankshaft: under the starter and on the drive, and it is better to change them with a couple. Having reached the place of installation, evaluate the condition of the eye: they should sit tight, without backlash and not to bulge, not to be cracked. Oil Sunses around also indicate the need to replace the seals.
When reverse assembly, be sure to use thread fixers wherever they were. this is a security issue.
To easily pull out the seal, screw into it 2 self.tapping screws from the opposite sides. Pull the screws in turn with the help of pliers.
Restoration of the piston group requires a specialized tool. If you are not a car mechanic for a hundred, trust the restoration of a trimmer motor for the grass to a specialist.
When opening the cylinder, all surfaces are checked for chips, bullying, scratches. To determine if the piston rings are worn out, shake the connecting rod. The slightest backlash of the piston indicates the need to replace the rings.

The reasons for the weak.speed trimmer for grass
If users complain to the trimmer for grass, which does not gain momentum, this means that it works normally on idle, and when pressing gas does not develop the necessary power. This can happen as a result of a long downtime of the apparatus without activity. These problems are typical for gasoline devices, including the Husqvarna 128R, STIHL FS 38 and Hitachi different modifications.
Working with a trimmer, you need to monitor its behavior all the time. a drop in revolutions and unusual noises signal the malfunctions in the aggregate. Sometimes you give gas, and the trimmer for the grass swims. In such cases, the work should immediately be suspended, let the mechanism cool and start searching for possible problems. They can be of a different nature of both the technological plan and external factors related to the conditions and features of the operation of the device.
The trimmer for the grass starts and immediately stalls the reasons
In recent years, the gasoline trimmer for the grass has made the status of a textbook from the main tools in the arsenal of summer residents. And such actions are logical, because a motorized braid for grass allows you to quickly put a personal plot in order. But when it happens that the trimmer for the grass does not start on the hot and cool. In such situations, it is necessary without the help of others to establish the cause of the malfunction. Next, find out what to do if a trimmer does not start for grass. The prerequisites that for the most part lead to such troubles will be considered further.
Where to start the diagnosis of defects if a trimmer is not started for grass? In situations where the tool stalls immediately after launch, it is worth looking at the subsequent units of the unit:
Specifically, the breakdown of the above locations for the most part leads to the fact that a trimmer for grass is poorly started. It is necessary to consider how to remove such problems.
Suppose you don’t start a trimmer for grass. Then the beginning of everything needs to be checked whether the fuel in the tank is enough, to additionally evaluate the quality of the fuel consistency. It is necessary to refuel a motorized unit only with high.quality gasoline.
It is recommended to use fuel, the brand of which is not lower than AI-95. Refueling a trimmer for grass with fuel of unknown origin, acquired not at a gas station, is fraught with the appearance of frequent failures when working as a tool. This causes a breakdown of the cylinder-piston accounting system.
Repair under such circumstances often exceeds the price of the device itself.
Why is a trimmer not starting for grass gasoline? Incorrect preparation of fuel consistency can also lead to this, which consists of oil and gasoline. The proportions, in which the designated components are connected are indicated by manufacturers in the guide for the operation of a trimmer for grass.
Preparing the fuel mixture is not very recommended in large volumes, in other words for the future. Indeed, with prolonged savings, the loss of the determining parameters of the substance occurs.
If a trimmer for grass does not start, it is worth draining old fuel and use freshly prepared fuel consistency.
The trimmer for the grass on the cold is poorly started, what to do?
What to do if the used fuel mixture is in perfect order, alas, as before, a trimmer for grass is not started by gasoline? The prerequisites for the refusal of the mechanism are variations to cover in excess moisture of the candle channel. To diagnose and eliminate difficulties, you need to make the next:
- Turn the candle. Wipe it painstakingly, and then dry it.
- Drain the excess combustible in the chamber through the corresponding candle hole.
- Clean an old candle if there is a dozen on its surface. The use of an ordinary ladies’ nail file or file will allow you to cope with the task.
- To install the element in the area, set a gap of 1 mm. To check the parameter, it is enough to place any coin in the lumen.
- Collect a multifunctional block back.
- Try to start a trimmer for grass.
It is recommended to do drying the candle channel by minimum within half an hour. But do not resort to calcining its parts. After all, heating the spark plug leads to its ultimate corruption.
Что сделать, если сервис многофункционального блока выполнялось согласно вышеуказанным советам, но триммер для травы не заводится, искра конечно при всем этом? Here it is worth treating gasoline threaded connection. The latter should not be plentifully impregnated with combustible. It is only a little moisturized.
Resort to such actions should be to ensure the ignition. After all, no matter how the candle gives a strong spark, in a completely dry chamber there simply will not be something to ignite.
If even a trimmer for grass does not start here, it is worth evaluating the quality of contact between a high.voltage wire and a candle. For which the design of the absence of a spark is intended (in the presence of a reliable connection with the designated elements), for sure, the inconsistency is caused by the breakdown of the ignition unit. In this situation, you will have to turn to the services of masters who will reinstall the knot.
After starting, the engine immediately stalls? why is this happening
Another all.produced prerequisite, because of which it is required, does not start a trimmer for grass, is the presence of a blockage in the filter area. To confirm the hypothesis, quite dismantle the designated block and experience the unit without it.
If the engine of the trimmer for the grass has launched, most likely you will have to create a change in the air filter or at least perform a painstaking blowing of an old. In the presence of abundant contaminants on the filter element, you need to use the latest grid. Relying to similar actions, it is not recommended to leave an absorbing pipe completely without a filter.
After all, haste in our version leads to the need to repair the entire piston group of the unit engine.
Often the engine of branded models of trimmers stalls during the clogging of the sapun. The main task of the designated component is the leveling of pressure in the fuel tank. For which the design of the node is intended here, a vacuum appears here, which greatly complicates the supply of fuel. Removing a malfunction allows the cleaning of the cabin using an ordinary sewing needle.
The measured functioning of the trimmer for the grass will be more impaired due to the laying of dirt in the final channel or the formation of blockage on the muffler grid. Such a disorder in most cases appears during the operation of the older generation trimmers. The issue is being solved by dismantling the anti.diploma mesh and its cleaning.
So that the unit is always in a multifunctional state, it is worth observing several ordinary rules:
- Carry out timely, constant technical inspection of the main mechanical nodes of the device.
- To refuel a trimmer for grass only with the latest fuel, the quality and origin of which is not caused by fluctuations.
- To inspect after each use of the tool, whether oxides and soot formed on parts of the accounting ignition system.
- Avoid the strong load of the trimmer for grass during work.
saw stall when you press the gas
So that the unit remains in a working state, you need to correctly prepare it for storage during the cold period.
Trimmer does not start for grass. Why?. Agrotechervice
A gasoline trimmer for grass is an amazingly useful thing, with the help of which you can, without unnecessary troubles, put in order not only a miniature lawn in the backyard of the house, but also to dig a considerable size of the lawn. But, like all things in this world, it has the ability to break. In this article, we will try to figure out what to do in cases where a trimmer for grass refuses to work.
The gasoline trimmer for the grass is poorly started
So, what to do if the gasoline trimmer for the grass is poorly started or not started at all? The most common reason for such a breakdown.This is poor.quality fuel. Remember that, for example, trimmers for the grass of brands “STIHL” and “Husqvarna” are unlikely to start the quality below AI-92.
Do not save on fuel, t.to. Repair of cylinder parts.the piston group can be a third of the entire cost of a braid for grass, and sometimes even half. Also, when preparing the fuel mixture, it is necessary to correctly observe the proportions of fuel and oil, which are always indicated in the instructions for the trimmer.
What to do if high.quality fuel is flooded in the gas tank, there is a spark, but the tool still refuses to start up? It is necessary to check the condition of the candle. It is located in the center of the gas mowing housing. It needs to be carefully twisted and make sure if there is a raid on it. If it is, then carefully clean the candle from the carbon and dry it.
If the lawn mower does not start even after the methods proposed above, then you need to try to remove the air filter and start the device without it. If the trimmer for the grass has not earned, clean the old filter well from dust or buy a new one.
It also happens that the lawn mower works as a maximum of 5 minutes, and then stalls and does not start until it cools down. In this case, try to open the pouring cover of a benzogornin. a suction sound should appear.

After that, tighten the lid back. If you do this manipulation during the time when the trimmer for the grass has just begun to stall, then the turns will recover, and it will be possible to continue to work.
If the lawn mower stalled until the cover is opened, then you just need to start it as it should be according to the instructions.
Trimmer for grass does not start after winter
How to be in such a situation? Do not worry and panic. This is a very common problem that is solved in just 3-4 minutes. Firstly, if the fuel is left in the gas tank last year, then it must be drained.
Gasoline loses its octave properties after 2 weeks of downtime. Secondly, start a lawn mower after a long stagnation in a slightly different way.
First you need to open the damper and pump up a little fuel mixture into the carburetor, then stretch the handle until a small resistance is sensed. After that, you can start a trimmer for the grass.
Trimmer for grass starts and stalls
If, when trying to start a trimmer for the grass, it starts up, but immediately stalls, then the cause of this may be an air filter again. It is necessary to remove it and check if it is clogged with dust.

If this is true, then it is necessary to carefully clean it or purchase a new. Also, the problem may also consist of malfunction of the ignition coil.
