Trimmer does not start for grass. Why?
A gasoline trimmer for grass is an amazingly useful thing, with 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.
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.
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. In this case, the lawn mower is best taken to the service center.
Malfunctions that can be eliminated independently
When your gasoline law mower does not start. First of all, it is necessary to check the presence of fuel in the tank. If it is absent. share it to the desired level. Often, when the device is not used for a long time, gasoline is “exhausted”, so it must be completely drained and seasoned with new. A similar procedure must be done carefully so that the fuel does not get to the engine, since this can lead to the fuse in the future (when the engine is heated). Which gasoline is better to use, you can learn from the technical passport of the device.
In order for the unit to start, you need to pump up a combustible primer (if it is in this model) in the carburetor and set maximum speed. You need to start equipment gently. The starter cord must be pulled smoothly until it stops, after which to pull on yourself with one even sharp movement.
A problem may occur with the improper location of the air damper during the first launch. Depending on the air temperature, it is completely closed or set to the middle position (above 30 s). Then it must be completely opened.
Check the air filter, if it is polluted. To do this, turn off the device and disconnect the wire from the spark plug. Unscrew the lid and remove the filter. Rinse it with gasoline and dry thoroughly or just put a new. Remember that changing the air filter is recommended after every 25 hours of operation.
Another reason why the gasoline lawn mower is not started, there may be a faulty spark plug. Perhaps she was just flooded with fuel. In this case, unscrew it, clean it and check the presence of a spark. It may be absent with a candle with fuel. Install the control handle of the air damper (if available) to the “closed” position and start the engine. If this did not help, it is better to seek help from a specialist.
If at the first launch, your new lawn mower refuses to start, try the following: based on the air temperature on the street, set the appropriate position of the air damper (at a temperature of less than 30 s. the “cloth is closed”, over 30 s. half.closed position), then pump up into the carburetor fuel and neatly, but rather sharply jerk to the sensation of some resistance to the lancet of the starter. Repeat these actions in the same sequence several times. A completely new tool should start. If this finally happened, you can safely start work, having previously completely opened the damper.
If the lawn mower is no longer new, then it is necessary to start its inspection from the gas tank. If the device has not been driven for a long time, then it is necessary to drain the old gasoline, which has a feature of “exhaling”, t.e. lose your octane properties, and pour a fresh fuel mixture. The ratio of gasoline/fuel, as well as their necessary brands are usually indicated in the instrument operation instructions.
Now you need to check the spark plug. either the problem in it itself, or in the fuel system. The candle must be carefully removed and appreciated its condition. If the candle is very flooded or there is a black fog on it, then it needs to be removed, clean and dried. Drain the excess fuel, if any, from the candle holes, drain the cylinder itself, then screw it dried or, even more desirable, a completely new candle. If the candle was originally completely dry, you need to look for a problem in the fuel supply system. First check the fuel filter. To do this, disconnect the suction hose and remove the contaminated filter from it, clean it and return installation, or change it to a new. If this did not help, it is worth contacting the specialists of the service center.
Not starting after winter
In this case, you just need to drain the old and, possibly, even frozen fuel and pour a freshly prepared mixture. Then you need to make the same manipulations as during the first launch of the lawn mower.
Starts and stalls
If the lawn mower stalls after starting, it is necessary to check the air filter. When this filter is strongly clogged with dust, it stops letting the required amount of air into the carburetor and allows dust entering the fuel mixture. It is necessary to carefully remove the contaminated filter, clean and rinse in gasoline. If the air filter is clean, and the tool still stalls, then to establish the cause of the malfunction and its elimination, it is better to contact professionals.
Recently, a gasoline trimmer for grass has acquired the status of one of the main tools in the arsenal of summer residents. And this is not surprising, because a motorized braid for grass allows you to quickly put a personal plot in order. However, sometimes it happens that a trimmer for grass and even for cold. In such situations, you have to independently establish the cause of the malfunction. Let’s find out what to do if a trimmer does not start for grass. The reasons that most often lead to such troubles will be considered further.
Checking the fuel mixture
Suppose you don’t start a trimmer for grass. In this case, the first thing is to check whether the fuel is enough in the tank, as well as evaluate the quality of the fuel mixture. To refuel a motorized unit, it is necessary exclusively 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, not bought at a gas station, is fraught with frequent failures in the work of the tool. This can cause a breakdown of the cylinder-piston system. Repair in this case often exceeds the cost of the device itself.
Why is a trimmer not starting for grass gasoline? Incorrect preparation of the fuel mixture may also lead to this, which consists of oil and gasoline. The proportions in which the specified components are connected are indicated by manufacturers in the guide for the operation of a trimmer for grass. Preparing the fuel mixture is extremely not recommended in large volumes, that is, for the future. Indeed, with prolonged savings, there is a loss of the determining properties of the substance. Therefore, if a trimmer for grass does not start, it is worth draining the old fuel and use freshly prepared fuel mixture.
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.
Dry and wet candle what it means and how affects the launch of the motor
Most of the owners of the tools immediately resort to checking the state of contacts of the spark plug. This is done in order to understand, by the state of the candle, what could be the reason for the impossibility of starting the engine of the lawn mower. According to the state of the candle contacts, you can draw the appropriate conclusions about what can be the cause of the malfunction. Diagnosis of the spark plug on the trimmer is performed in the following order:
- The spark plug unscrews, after which it is subject to inspection. The ideal state of the electrodes. if they have a brown carpet (brick color). If the candle is wet, has a black or white fog, then this indicates the corresponding faults
- If the candle is wet, then in the combustion chamber there is a portion of unbroken fuel, which does not need to be drained. Clean and dry the contacts of the spark plugs, then make sure of its serviceability. To do this, connect it to the immunity, and place it not the surface of the cylinder. Turn on the ignition and pull the starter handle easily. In this case, the candle should issue a quality and constant spark. If the spark is weak or it is not at all, then the spark plug should be replaced
- A trimmer does not start for grass may not be started due to a large gap between the contacts of the candle. The gap between the electrodes of the spark plug should be in the range from 0.7 to 1 mm. Special probes are used to set the gap
It is interesting! Dry candle contacts by pumping it is strictly contraindicated, since this method will lead to damage to the details.
If there is a spark on the candle, but the trimmer for the grass does not start, then the reason is the supply of the fuel mixture in the combustion chamber. To make sure this, you should perform the following actions:
- Dial in a cap made of PET bucks or in a syringe of 20 grams of fuel
- Pour it into the combustion chamber through the candle hole
- Twist the spark plug
- Put on a candlestick and start the engine
If the engine of the lawn mower starts after the actions performed, then the cause of the malfunction should be sought directly in the fuel line and carburetor. If the motor does not start even after the actions done, then you need to check the serviceability of the high.voltage wire. The high.voltage wire, like the spark plug, refers to consumables. If there are suspicions of a malfunction of the armor of the trimmer for the grass, then it should be replaced
If, after the actions done, it is not possible to launch the engine of the lawn mower, then the following recommendations must be taken into account:
- If there are doubts about the serviceability of the spark plug and high.voltage wire, then it is recommended to immediately replace them
- Check the serviceability of sparking, and if there is no spark on the new candle, then the breakdown is associated with the ignition unit. the failure of the coil is out of order
- The ignition coil is not repaired, but changes. If the diagnosis really indicates a malfunction of the ignition of the lawn mower, then it is not difficult to replace it with your own hands
If there is a candle on the spark, and at the same time it is dry, and the trimmer for the grass does not want to start, then we move on to check the next node. air and fuel filters.
It is interesting! If the candle electrodes have a red or pink color, then this suggests that the composition of the fuel used contains a large number of additives. You should abandon such fuel by changing a gas station or a brand of gasoline.
Features of diagnosis
Trammers for grass can be attributed from a technical point of view to complex devices. Based on this, before their operation, it is strongly recommended to carefully study the relevant instruction. However, in practice, many ignore it, often then find themselves in situations where the gasoline trimmer for the grass does not start or is poorly gaining momentum in the process. It is worth noting that you can encounter such problems by purchasing new samples of technology.
The key to effective and operational repair will, of course, be competent diagnostics of the device. In the process of identifying malfunctions, you will have to inspect and test, first of all, key elements. The list of such includes candles, tank, filter nodes and valves of the fuel system. As practice shows, very often the malfunctions of these elements become the reason that the lawn mower does not start. The quality and correctness of the preparation of the fuel mixture deserves special attention, especially when it comes to two.stroke engines. In relation to this parameter, the manufacturer’s recommendations should be clearly followed in order to avoid serious breakdowns and expensive repair work. In the case of, for example, with the Piston Group of ICE, expenses are able to amount to 70 percent of the cost of new equipment.
Often, the owners of the trimmers have to deal with situations when the indicated mixture is high.quality, the carburetor is serviceable and configured, and the device still does not show signs of life when trying to start the engine. In such cases, the condition of the candle should be checked. The following steps will allow to eliminate the problem:
- turn out the candle;
- wipe and dry the part (pumping is undesirable);
- remove fuel and dry the candle channel for 30–40 minutes; Such actions will avoid filling the candle with another attempt to launch;
- completely eliminate the traces of soot using a file or sandpaper;
- set the appropriate gap;
- put the candle in place.
If the candle turned out to be the working and the planting nest is completely dry, and the engine of the braid for the grass is not started, then the thread should be moistened with gasoline. It is worth remembering that regardless of the quality of the issued spark, initially in a completely dry chamber, there will simply be nothing to ignite
Faced with the fact that the spark does not act, it is worth paying attention to checking the contact between high.voltage wiring and candles. If this connection is of high quality, then it will be necessary to check the performance of the ignition control unit unit
In such cases, a qualified specialist is unlikely to do without services.
The next stage in the diagnosis of gasoline braid for grass will be checking the state of filters. Often, the lawn mower is poorly started or does not start at all on the cold due to the fact that the air filter is clogged. This malfunction can be identified by excluding it from the system. If after that the braid for the grass starts, then you will have to clean or change this element. Experienced users strongly recommend periodically blowing an air filter to maximize its operation.
The described tool can also not be started due to problems with the supply of gasoline provoked by fuel filter pollution. For the quick and efficient elimination of such a breakdown, you just need to replace the filter element with a new
It is important to remember that the suction pipe must be equipped with a filter, which is provided for by all instructions. Non.compliance with these rules and recommendations may entail expensive piston repair
In the process of diagnosing and searching for source of problems with the launch of a mower, attention should be paid to the saapun responsible for stabilizing the leveling of pressure in the fuel tank. In addition, it is necessary to check the cleanliness of the exhaust channel and muffler grid
As a rule, such problems are most often encountered during the defect of old models.
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.
Next, watch the video on how to determine and eliminate the reason why the gasoline trimmer is not started for grass.
The lawn mower is not started after winter
In such cases, it is necessary to conduct maintenance of the unit. Remove the fuel system, including filters (air, fuel), disassemble the carburetor, clean each node, rinse. Pour the filters with air. Pay attention to the quality and octane fuel number.
It must be taken into account that the products of such well.known companies as Stihl, Husgvarna and other brands will not work on a cheap octane number of gasoline. For them, suitable fuel from the AI brand. 92 and higher with car gas stations and that, with well.proven ones, since gas stations are also bad gasoline. On the use of highly octane and high.quality gasoline, it will depend on how long the lawn mower will be used and how much it will last.
One more fact must be taken into account that with the long storage of diluted fuel mixture, it falls working qualities, which also leads to the consequences in which the lawn mower will not start. Therefore, it should be diluted with portions, that is, the amount of a mixture that is produced at a time. The operating instructions clearly describe and are given clarifications on the proportion of mixing gasoline and oil. Straighten compliance with the correct proportions will at least save you from several questions, why the lawn mower will not start and what to do in such cases.
The lawn mower starts and stalls. What to do?
There is a spark, and everything seems to be normal, but the lawn mower is not started, in such cases, you should check the air access valve into the fuel tank. Clogging of the valve leads to the creation of a vacuum in a tank, in which the carburetor does not receive gasoline, so the lawn mower will start, but then it will die out. To exclude this reason, you need to clean the valve and try to get a lawn mower with a not fully twisted tank traffic jam. 2. If at the same time the lawn mower is not started, you should remove and clean the fuel filter, as well as check all the parts of the carburetor, and then try to start. The lawn mower is not started again, the air filter is disconnected, try to get without it if the gas station has started to mean the reason in the air filter, replace it.
The loss of the spark entails a check of contacts and the correctness of the clearance between them, conducting the wire to the candle and the candle itself. A method of checking the spark. to unscrew the candle, connect the wire to it, attach the candle sideways to the casing of the engine and pull the lawn.mower as if starting the starter several times, while you need to look at the corner and contact of the candle, the spark should run between them. If there is no sparks, take a new candle to do the same procedure, if the spark is not traced, the problem in the wire or contacts means it, it is better to replace them.
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.
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.
Another all-produced prerequisite, due to which a trimmer for grass does not start, 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 an air filter substitution or at least perform a painstaking blowing of an old. In the presence of abundant contaminants on the surface of the filter element, you need to use the latest grid. Relying to similar actions, you should not leave an absorbing pipe completely without a filter. After all, rush in this case can lead to the need to repair the entire piston group of the unit engine.
Cleaning the soundtress
Often the engine of branded models of trimmers stalls as a result of clogging of the sapun. The main task of the designated component is the leveling of pressure in the fuel tank. In the case of contamination of the node, a vacuum appears here, which greatly complicates the supply of fuel. The lawn mower is not started or the reasons for the malfunction of the lawn mower are not started on a hot. Removing a malfunction allows the cleaning of the cabin using an ordinary sewing needle.
The measured functioning of a trimmer for grass may be impaired as a result of laying dirt in the final channel or the formation of a blockage on a 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.
The lawn mower starts poorly? Adjust Magneto’s gap
As the experience of operating benzos, in particular Chinese production shows, they often have problems in the launch system, so they are often difficult to start. Problems are usually related to the flywheel magneto.
For those who are unfamiliar with this unit, we remind: this system consisting of ignition coil, spark plugs and flywheel with magnets. We have to deal with the clearance of Magneto, more precisely, with the gap of the ignition coil and its guaranteed exhibition. It is because of it that problems arise in Chinese units, which for several years were operated in domestic conditions or in the conditions of the Housingire. But it happens that even in new products it is difficult to start, especially for cold. And in this case, usually problems with the launch are related to the gap of magneto. Most people who operate the lawn mowers expose the Magneto gap of 0.4 mm, as recommended by many manufacturers. What will happen if this gap is adjusted and set 0.25 mm? It turns out that when it is reduced, the electric spark becomes thinner, smaller and practices every beat even with slow speeds of the Magneto flywheel.
That is, consciously reducing the gap, we thereby increase the likelihood of a normal launch of the lawn mower without any excessive physical exertion and shortness of breath even when starting a cold engine.
Gap and procedure for its exhibition in different cases
As a template, a strip of the required width and length carved from a conventional plastic bottle, for example, from under Pepsi-Cola, can be successfully used to put a gap of magneto.
It is only necessary to install it last, so as not to damage when carrying out repair work, using the same hair dryer for any purpose. After all, if it is crumpling from the effects of hot air, then there is no need to talk about the accuracy of the gap of Magneto. It is with the help of a spacer carved from a plastic bottle that you can with high accuracy set the Magneto gap 0.25 mm, since its thickness is exactly the same. To make sure of this, it is enough to fold the strip four times and measure its total thickness with a caliper, which will be exactly 1.0 mm. We put a spacer cut from a plastic bottle on the magnets of the Magneto flywheel, set the ignition coil in place and fix it with strong bolts of 8 by 8, after filling the holes with a thread on the case with a threaded latch.
We apply it on the bolts, twisting which, you must not forget to fix the terminal of the mass. It is better to use an electric screwdriver at the same time. We squeeze the bolts with a regular hand screwdriver with a hexagonal bat to the limit, since the use of a M-shaped hexagon can lead to a breakdown of the faces of bolts.
Замена масла в бензиновой газонокосилке\боковой выброс\мульчирование\ VLOG
It remains, turning the flywheel with magnets, remove the plastic spacer and, continuing to rotate it, check the quality (uniformity) of the clearance when it turns from 0 to 360 degrees, which, with this approach, is ideal. Some use the Magneto’s gap folded by half a photochex leaf, which is also permissible, but the use of a spacer from a plastic bottle gives the best result. over, it can be used reusads dozens of times.
It remains only to install body parts and you can run the engine to test how it starts and works. Sometimes during operation, the ignition reel reels are deformed to the magneto housing, which does not allow you to reliably install it, since the holes in the coil and on the engine body do not coincide.You can, of course, try to straighten out the defect, but it will be more reliable to put a new coil, especially since it is not too expensive.All further actions are similar to the above case, unless the heads of fastening the spark plots can not be under the hexagon, but for the wrench and the cross.shaped screwdriver. But this does not change the essence of the matter: the tightening of these bolts should be guaranteed to be reliable, as in the first case. To evaluate the quality of the work done, it is necessary to make sure there is a spark between the electrodes of the candle visually after the final assembly of the engine. To do this, we connect it to the mass and begin to turn the engine using the starting device of manual or electric. The check for the spark has one nuance. If you sharply pull behind the kicks starter, then the spark will appear even with slightly faulty magnets of magneto and even completely non-working ignition coils. In this case, the presence of a spark is not yet an indicator of the serviceability of the ignition system.The quality of sparking can only be judged by its appearance, when the flywheel Magneto does not rotate too quickly, for which the kicks starter should not be pulled, but evenly and not to pull.
Only in this case, the engine of the benzotrimer or chainsaw will be started without problems, both in the morning and throughout the entire working day (respectively, the so.called hot or cold launch). If there is no spark with a slow movement of the starting device, then, most likely, you will have to change the ignition coil, set the gap of magneto or change the candle.The practice of putting a gap on benzos and chainsaws described above for five years has justified itself completely. There have never been complaints from users after such a repair. This really helps when starting not only Chinese gasosos, but also European and even branded. At all units, regardless of the manufacturer, putting the Magneto clearance 0.25 mm instead of 0.40 mm recommended by manufacturers, gives excellent results. Some people offer gaps 0.10-0.15 mm, but this. After all, there is a certain thermal expansion of the parts of the ignition system, the housing itself, the gas mower or chainsaw crankcase, and such a small gap can disappear altogether, which can lead to breakdowns (burning out), first of all, the ignition coils. Therefore, a gap of 0.25 mm is from all points of view optimal.
