The lawn mower began to start poorly. With gazeaming

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.

Air filter

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.

How a two.stroke engine works: briefly, but it is important to know for a clear launch of a lawn mower

Lawn mowers are produced with two.stroke or four.stroke internal combustion engines. The difference in the design is significant, but each model starts on the general principle. I show on the example of the Chinese trimmer for Eco grass.

The engine is called two.stroke because the full.time cycle is two tacts: the stroke of the piston from the upper dead point of the VMT to the lower NMT. In this case, the launch occurs with the second achievement of the upper position.

Similarly, chainsaws, boat engines and gasoline tools of another similar technique work. Consider the procedure. We are supposed to figure it out.

To start a trimmer motor for grass, we pull the starter’s cord. Its stretching is spinning a crankshaft with a flywheel creating the moment of inertia. The rotation of the crankshaft shaft is converted into the reciprocating movement of the piston.

The two.stroke motor has 4 working cycles:

  • The first movement of the piston from the VMT to the NMT is accompanied by the injection of the fuel mixture (gasoline with butter and air), when the carburetor inlet valve opens under the influence of the created vacuum;
  • The movement of the piston from NMT to the VMT: the intake and exhaust valves are closed, and the working mixture is compressed in a sealed volume;
  • Both valves remain closed. At the upper dead point of the piston through the contacts, the spark slides through the contacts.There is an explosion of compressed gases. Its strength with an impulse throws the piston down and rotates the crankshaft through the connecting rod;
  • The force of inertia of the flywheel directs the piston from the NMT up: the exhaust valve opens and through it the combustion products are pushed into the exhaust pipe.

All stages are performed automatically, but they are prepared by a person with his actions. When making errors it is made, the benzotrimer does not start and may break.

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.

Symptoms

The first thing the user may notice. This is a deterioration in the quality of the device. The grass is not mowed smoothly, there are no spots on the lawn. This is because the engine begins to doze, its power is reduced. TOP 5 symptoms that indicate a malfunction:

  • Increased fluctuations in the device.
  • Increased noise when working.
  • The lawn mower starts and goes out.
  • The device turns off.
  • The car whistles.

3 The main causes of the mower are worth. Incorrect work, overload, long.term operation (engine overheating). The system is cooled by an air filter and should be checked every time the garden technique is used. What to do so that the mower does not hold. Before turning on the device, check the presence of gasoline in the tank for the presence of oil. It is recommended to clean the filter after each mowing.

How to run a lawn mower when the engine is at home

It is especially difficult to launch a mower after a long time of downtime, what to do to the user, when the garden equipment refuses to work:

  • If the device was not cleaned for a long time, it is necessary to rinse the air engine, it is cleaned with gasoline (preferably every 24 hours). You can remove the filter from the device and start the unit if the mower is working, this is the reason.
  • After winter, the remaining old gas in the tank can interfere with the work of the device. The problem is easily solved if you replace the fuel with a new.
  • The deficiency of oil in the crankcase may also be the cause of the lawn mower does not start. Check the fuel for the presence of fuel in the tank.
  • Incorrect position of the throttle at the first launch. At a temperature of ≥ 30 ° C. It should be in an average position or close. After rebooting. open.
  • Jamming of the crankshaft, piston. can be removed by slightly shifting these details. The main thing is to do it carefully so as not to break the mechanism.
  • Respiratory pollution. Fuel supply is stopped, the part must be cleaned.
  • Dry threaded connection. In this case, the factor does not have a spark of ignition, lubricate the connection of gasoline.
  • Faulty spark plug. Oil accumulation on it, plaque. The candle is twisted, well dried, peeled with a nail file. Excess fuel is drained, dried for at least 30 minutes. Candle hole. If it cannot be cleaned, it may be necessary to replace the part.
  • The contact of the high.voltage wire and a candle for the presence of a spark is also checked. If the latter does not occur, the ignition system malfunction will be identified and eliminated only by the service center.

The lawn mower began to start poorly

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 ”.

Immediately after you started

The unit can stall immediately after the launch, if the carburetor is sipped or incorrectly configured. this causes an uneven supply of fuel. The result is that the device begins to vibrate clearly. To eliminate problems, the carburetor is reconfigured, acting according to the instructions for the mechanism.

The engine also stops when the valve supplies fuel clogs. In such cases, it is enough just to clean it. If the lawn mower at first earned, but then immediately stalled, then possible fuel to the carburetor unit enters some difficulty. The weakening of the valve helps to solve the issue, which provides free circulation of the mixture in the system.

The stop can also be caused by air leaks in the presence of mechanical damage to the hose (holes, cracks) that fuel fuel fuel. In this case, the drive should be added to the drive to quickly drive air bubbles from the system.

When heated

The lawn mower often stops when heated. In this case, it starts, works “with jerks” and gradually stops. This process occurs when gasoline in a carburetor boils or a damper in it is installed by a rotary rather than a disc. In the latter case, the part is changed.

It is found that the trimmer for the grass is heated if the ignition circuit or the coil is damaged. To start working normally, the device is replaced by details.

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.

Also, the ignition coil can be broken in electrical equipment. In this case, the lawn mower will not start or start and works with interruptions, and then stalls, or “hot” does not start at all.

You can check the serviceability of the coil in the same way as when checking the spark: we unscrew the candle, lean it against the trimmer body for the grass. If there is no spark with a jerk of the starter, or it appears through time. you need to change the coil.

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.

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
