The reasons for the non -operation of the trimmer for grass of the gasoline engine. The air filter is clogged

Why the trimmer for the grass does not start: the causes of the malfunction and ways to eliminate them

It’s time to cut the lawn, and the lawn mower does not work? It’s even scary to imagine how to maintain the lawn in perfect condition with a manual tool, especially when this was not done before. If a trimmer for grass does not start, the reasons can be very different, but you can eliminate most of them yourself.

This will not need either a special tool or highly specialized knowledge. A little courage and free time to read this material. and a trimmer for the grass will not need to be taken to the master.

In this article, we will tell you how to determine what exactly interferes with the launch, we will give instructions for the repair of each node and recommendations on how to avoid problems in the future. For clarity, photos and videos await you, where the most common breakdowns are clearly dismantled.

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

The reasons

Trammers for grass are reliable and durable (of course, subject to proper care). Most often, malfunctions arise due to contamination of structural elements.

If the engine of your lawn mower does not start, does not gain momentum, does not reach the power you need or suddenly stalls, it may be a reason:

• low.quality fuel (fuel mixture), it can be in long.term storage or in non.compliance with the recipe for the preparation of the mixture;
• The grass was wound on the shaft of the fishing/knife head;
• clogging of the air filter/muffler;
• Balance of the carburetor.

Ways to eliminate problems

The first three reasons are quite simple to eliminate. If the matter is the mixture, it is necessary to pour old fuel from the tank, prepare a new emulsion from high.quality gasoline and engine oil (if your motor requires a mixture) and pour it into a fuel tank. If a trimmer for grass works on clean gasoline, it’s still easier.

In the second case, it is necessary to carefully release the details of the trimmer for grass from the wound grass.

If the filter is clogged, you can try to rinse it. If this procedure has not brought the effect, replace it with a new.

The last reason why the lawn mower does not work properly will require you a little more knowledge and skills.

In order to properly adjust the carburetor of the lawn mower, it is necessary to observe a certain procedure. First of all, carefully clean the air filter. The easiest way to rinse it (it is advisable to carry out the filter with water regularly after 9-10 hours of operation).

After that, in the diagram of your trimmer for grass, which is in the instructions for the operation of the device, find the adjustment screws. Usually there are three of them: the first is responsible for the supply of fuel, the second. for idle, but the third is designed to limit the number of maximum engine speeds.

Next, you should turn on the unit and wait for the engine to warm up.

Slowly twist the first adjusting screw (fuel mixture). Catch the moment when the motor begins to stall, and turn the screw in the opposite direction 45 degrees. If you did not have time and the motor stalled, the screw should be turned 90 degrees. Open the throttle and see how the speed is going. Next, you should slowly unscrew the screw (each turn. the same 45 degrees) until the moment when, with full gas, the motor begins to firmly issue maximum revolutions.

The second screw, as mentioned above, controls the engine speed at idle. Weakening it, you reduce the number of revolutions, tighten. increase. The screw must be adjusted so as to ensure confident operation of the motor at small speeds. Accelerate the engine for better starting a little. At the same time, make sure that before the movement of the knives/coil with the fishing line, the motor makes several dozen revolutions. With poor starting the engine, screw the screw slightly.

After you have adjusted the first two screws, test the operation of the device at the maximum engine speed. If necessary, you can limit it (maximum). this will serve as protecting the motor from “boiling”. To do this, you need to do the third screw. Unscrew the fixation nut until the moment when the control screw can be calmly turned. To increase the maximum speed, the screw must be loosened to reduce. on the contrary, tighten. Fix the screw position with a nut. Test the work of the motor again.

Spend the position of the screws regularly. a high level of vibration characteristic of benzocoses can cause their involuntary shift.

Remember that carburetor adjustment is not the final procedure. During operation, Motokos, most likely, you will have to mess with it more than once, because an unbalanced carburetor is both an increased fuel consumption and a quick failure of the candles, not to mention reducing the power and productivity of the device.

Ways to eliminate breakdowns

The following works are possible by carburetor:

• cleaning and adjustment of the fuel supply valve;
• similar work with a valve producing spent gases and pairs (after fuel burning);
• replacement of the spring weaker on the entrance valve;
• restoration of the tension of the carburetor cable;
• replacement of the fuel leaks hose, verification and strengthening of a weakened connection;
• changing the rotor damper disk;.
• Change of faulty wire or ignition coil.

The list of work on the work may also include the cleaning of the nozzles (in a 4-stroke engine), replacement of the valve washer, gaskets in tanks and so on.

Operating advice

It is worth paying attention to several recommendations for working with a benzoca or a trimmer, extending the service life of the device to several times.

• As soon as you notice that the lawn mower or trimmer vibrates for the grass. immediately stop working and check the serviceability, performance of specific parts.
• Valves adjustment and checking the work of pistons and cylinders, cleaning and changing the nozzles perform, starting from the requirements set forth in the user guide and the recommendations of the masters of service centers.
• When air bubbles enter the system due to impaired fuel hose-give in to gas. With the combustion of gasoline with higher speeds of the gas bubbles motor will be less. But this is a temporary measure. As soon as possible, disassemble the unit and eliminate the cause of the suction of excess air.
• Do not work as a unit in cold weather, not heating the engine. under load it can often stall. The effect here is the same as in the case when the driver in.40 started the car and immediately drove off, without waiting for the engine heating.
• Do not leave the unit on the roadway. During the accident, the hit will immediately break, and this will make the purchase of a new unit for a forced measure. A car that has crashed into it at best will receive damage to the body and bumper.
• Avoid working with a motorcycle or a trimmer in a downpour. Water getting along with air in the worst case can lead to engine explosion. Similar situations arose with cars.
• Do not use unverified vehicles and lubricants. The mower warms up the engine more than it would do the car itself. when overheating, it will automatically lose its lubricants. It will turn into a burned out reagent. sticky, too viscous and viscous, like fuel oil. He will immediately stall (and drown out) the motor.
• If the oil is old, previously merged from the tank of the machine or other (or the same) lawn mower (on a 4-stroke engine)-defend it, filter to clean from dirt and metal. But at the first opportunity, purchase fresh motor oil.
• If the engine is two.stroke. observe the ratio of gasoline and oil. For compositions with mineral oils, this is approximately 34: 1, for semi.synthetics. 42: 1, for purely synthetic. 50: 1. Do not violate these proportions: “rewinded” gasoline will not burn out and quickly clog the engine, “under.appropriate”. will accelerate the wear of its mobile parts.
• In terms of viscosity to winter classes, they include marking oils: SAE-0W/5W/10W/15W/20W/25W. To the summer-SAE-20/30/40/50/60. For example, SAE 10W-40 is already all-season oil (when working mowers from spring to autumn inclusive). Be sure to check with the manufacturer exactly what oil is needed.
• Always use high.quality gasoline that has passed the manufacturer all stages of cleaning.
• Recommended octane number of gasoline-AI-92/95/98. The use of the 76th can lead to a non-power of the engine by frequent stalling if you are poured, for example, the 76th or 80th gasoline.
• If you are not sure of the independent solution of problems with a gas station (which does not gain move and often stalls)- call the master or contact the service center for repairing motor and garden equipment. Specialists do not get used to doing this work for you.

Observing all these precautions, you will give your mower for many years of fruitful work, and yourself. the luxury of well.groomed lawns, comfort and convenience when mowing unnecessary vegetation in your site.

The reasons for the non.operation of the trimmer for grass of the gasoline engine

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 ”.

Recommendations for operation

The stability of the work of any motorcycle and the lack of problems with the launch of the power unit of such devices directly depend on the conditions in which the tool and quality of maintenance is used. And we are talking about the following basic rules:

• In the process, it is necessary to pay special attention to the cooling system and other elements; It is strongly recommended to timely and qualitatively clean the channels located on the hull of braids for grass and ribs of the starter;
• In the process of processing various elements, solvents, gasoline, kerosene and other effective means can be used;
• The indicated work should be carried out after completely cooled by the power unit;
• It is necessary to fully comply with all the rules specified in the relevant instructions drawn up by the developers of the described tool, which will avoid overloads in the heated engine, which in turn is the most common cause of serious breakdowns;
• All fuel remnants in the internal combustion engine should be completely drained before long breaks in operation of braids for grass; It should be borne in mind that the gasoline-oil mixture quickly decays into the so-called heavy fractions that inevitably clogging the carburetor;
• After removing the fuel, it is necessary to start the engine and let it work on xx until he himself stalls; Similarly, the remnants of the mixture will be eliminated from the internal combustion engine in full.

Particular attention must be paid to the preparation of the tool for long.term seasonal storage. This should be done to minimize the risks of problems with the launch of the engine. Competent preparation includes the following manipulations:

• completely disassemble the trimmer for the grass;
• Rinse and clean all the elements to which there is access;
• examine the parts of the lawn mower in order to identify defects (mechanical damage detected in this case should be eliminated);
• pour motor oil into the gearbox;
• carry out high.quality cleaning from clogging of an air filter element;
• Having appropriate knowledge and practical skills, you can perform partial disassembly of the power plant with subsequent purge and lubrication of moving elements;
• pour the collected gasoline braid with a pre.oiled rag.

In addition to all of the already listed, it is necessary to lubricate the piston group. This algorithm provides for the following simple manipulations:

• extract a candle;
• translate with the starter the piston to the upper dead point (VMT);
• pour a small volume of motor oil into the cylinder;
• Shine the crankshaft several times.

Regardless of the cost and brand of equipment, you should clearly comply with all the requirements of the relevant instructions and adhere to the recommendations of developers and experienced specialists. Today, detailed information regarding the correct use of such technology can be easily found on many specialized sites and forums.

It is important to remember that competent operation of motorcycles and its timely maintenance (independent or in the service) is a guarantee of the longest possible service life and minimum expenses.

How to prevent a breakdown during storage?

Lawn mowers are used in the warm season. For the winter they are cleaned in storage in the pantry, closet or garage.

Maintenance of the trimmer for grass should be produced several times a year (in t.h. after winter storage) to increase its possible service life

To prevent a tool breakdown, you need to properly prepare it for seasonal storage:

• Drain the fuel mixture. it must always be drained if you are not planned to use the device within a month, t.to. The fuel decays into various heavy fractions over time, which can score the channels of the carburetor;
• completely disassemble the lawn mower;
• Rinse, clean and dry all the details to which there is access;
• inspect all the elements of the trimmer for the grass for damage;
• eliminate all possible malfunctions, distortions and minor defects;
• pour a sufficient amount of oil into a gearbox;
• partially disassemble the engine;
• Rinse and grease all the necessary elements in t.h. piston;
• Clean the air filter.

If the lawn mower is stored outside the house and the residential area, it can be wrapped in an oiled fabric. This minimizes the risk of rust on the instrument and increase its life.

Thorough preparation and processing of a trimmer for grass will allow the device to keep the device for several seasons.

The lawn mower is not started? Eliminate the most common reason

Chinese motorcycles headache for the owner, but still without them nowhere. The main problem is the difficulty of starting after a long downtime. If the lawn mower worked as a clock in the fall, but it does not start in the spring, then you must most likely disassemble the carburetor and clean its valve.

Necessary tools:

If the motor motorcycles refuses to start, then first of all you need to check the candle. If it is completely dry, then this means that the fuel is not supplied to the combustion chamber and the reason is in the carburetor. Immediately it is worth checking the candle and for the subject of a spark in order to exclude it from the reasons on all fronts.

You can also make sure that the motor itself is serviceable. To do this, having twisted the candle, you need to pour a syringe into a combustion chamber of several milliliters of gasoline. After this, the candle is twisted and the lawn mower is started. If everything is in order with the motor, then it will work for a few seconds. This will once again confirm that it makes sense to disassemble the carburetor.

Next, a plastic protective cover is removed along with an air filter. After that, 2 screws are twisted with a cross.shaped screwdriver, holding the air damper and the carburetor on the engine. Fuel tubes immediately break down.

From the side of the cap of the suction, you need to twist 4 screws with a screwdriver, and divide it into 2 halves. We are interested in half with suction. There is a valve from its inside in the center.

He often sticks out, because after evaporation of gasoline, with a simple on it, a viscous oil works as glue. To check it, you need to put a short thin tube and try to blow the air through it. If he is stuck, he will not be able to blow out in any direction.

Caliping of the valve is eliminated by a conventional match. Toothpicks are better not to use, since they are sharp and can harm. A match must be slightly rested on the valve and stir it. After cleaning the match, it will be blown up.

Fuel will be able to act, so it will work. Cleaning the valve is not a panacea for all motorcycles that do not start after downtime, but this helps in 8 cases out of 10. The remaining 20%, as a rule, are also associated with a carburetor, usually with a needle.

What nodes need to be checked if there are problems

We give a list of problems and appropriate actions to solve problems. Some symptoms intersect, so it is necessary to carefully study the problem that has arisen.

There is a spark and a candle dry

• Check the fuel hoses and the fuel filter;
• Check the primer;
• Check the air damper drive;
• Check if it is a dirty carburetor;

There is a spark and a candle is wet

• Check the serviceability of the candle or clean the soil on its contacts;
• Clean the air fence filter;
• Check the course of the air damper;
• Replace fuel with fresh;

Does not start hot

• A filter of air fence clogged;
• Manual launch ventilation (starter) is contaminated;
• A large gap between the flywheel and the ignition coil;

Not starting on cold

• Inspect the air damper lever;
• Stretch the hilt of the air leaks (if the trimmer for the grass is equipped with it);
• Inspect and replace the primer as necessary;
• Adjust the gap between the flywheel and the ignition coil;
• Clean the swing valve;
• Check the piston rings;

Badly starts in all modes

• Clean the swing valve;
• Mix the new batch of fuel;
• Clean or replace the candle;
• Adjust the gap between the ignition coil and the flywheel;

Does not start after winter

The main reason for non.letters of motorcycles after incorrect conservation is stagnant fuel. thickened in fuel pipelines, it does not allow the engine to start. Therefore, it is recommended to preserve the tool before long storage.

Maintenance and prevention of launch problems

It will also depend on how to store a trimmer for the grass. For example, a trimmer for grass, stored according to all the rules, will not cause the owner of problems, and timely prevention (inspection and replacement of filters, fuel pipelines and mechanisms) will save a considerable amount of repair of motorcycles in case of unforeseen breakdown.

If everything is in order with electrical equipment, then we check the carburetor.

Vacuum carburetors are put on trimmers for grass. When disassembling it, cleaning or washing, you need to be extremely careful. in no case do not disassemble the lower part of the carburetor where the primer is located. Air filter (it is visible if you remove the protective casing from the carburetor) should be washed with detergents. Best. for washing dishes. After drying, we put it back. Rinse the carburetor with clean gasoline and blow out all the holes by the pump. We also wash the filter of the gas pipeline, then we dry everything and collect everything. Usually, after all manipulations, the trimmer for the grass begins to work.

Thin cable instead of fishing line, whether it is worth placing it on a motorcycle?

This thought comes to mind almost everyone who had to pump out 10 acres overgrown with high grass. At first glance, the idea seems good. The cable is stronger than the fishing line, not so wear out. However, not all so simple.

If you put a cable instead of a fishing line, without the possibility of its release, reliably fixing the two ends of the cable and cutting them with welding (a drop of melted metal holds the cable from blooming). Grass such a tool “falls” at a time. The shoot is cut off about a finger with a thickness. Stones are not as afraid as disk. There is true, the problem: when wear, pieces of cable threads break off, and these twisted wires remain in the place of mowing. If you step on them, you can get hurt.

But pieces of the cable remaining on the field are half a bastard. The fishing line for the trimmer, breaking off, weakens the dynamic blows to the transmission and the engine, the cable does not give such an opportunity. Result of quick wear of motorcycles.

It must also be remembered that a piece of cable, promoted by centrifugal force during the rotation of the trimmer head, flies like a bullet. Imagine what will happen if he gets in the leg or someone in the eye?

The use of a cable, wire, a multi.core cable instead of fishing line leads to a quick breakdown of a trimmer for grass. In addition, this is a direct violation of safety precautions!

Experienced users recommend buying a fishing line for a trimmer with a profile “Star”. Compared to round, it mows much better, stems with a thickness of a fishing line for a trimmer with a diameter of 3 mm chopping into a lightweight, and less consumed.
