Trimmer for grass stopped working at idle. Reasons why a new trimmer is not started for grass

Trimmer for grass gasoline works only at idle speeds

The lawn mower is a mobile high.performance tool for ennobleing personal plots and adjacent territories. With prolonged operation due to wear of parts or production marriage, there are malfunctions that lead to the fact that the trimmer for the grass stalls or does not start. Since this tool is a rather complicated mechanism, because the reasons why the lawn mower stalls can be several.

There are two main ways to eliminate problems: transmitting braids for grass to a specialized center or solving the issue with your own hands. The first option is suitable for those who are ready to lay out a “round” amount to restore the performance of the unit, and the second for someone who has basic locksmith skills and can independently deal with the causes of breakdowns and ways to eliminate them.

It is currently customary to classify breakdowns by which the lawn mower stalls in the following categories:

• mechanical damage to the ICE crankcase, malfunctions of the cylinder.piston group (CPG);
• breakage associated with the supply of fuel mixture (air filter, carburetor);
• problems due to damage to tubes, hoses, cables or ignition circuits.

Why is the lawn mower stall at idle

Why does the lawn mower stall when you press the gas: the prerequisites and their solutions. The lawn mower stalls (trimmer for grass):. On idle, users have repeatedly ask about stopping braids for the grass “on hot”, that is, when the mechanism started, worked a little, and then took it. and stopped, stalled stalled. The reasons for this situation are the following:

• problems with the carburetor damper;
• Gasoline in a carbe can even boil;
• If the ignition is damaged, then the trimmer for the grass will also heat up and stall.

In each of the situations, check the details for strength, and if they have already outlined their own, order new ones from specialists. We will call one of the most popular situations: the lawn mower stalls at idle. This happens for reasons:

• The carburetor was diluted himself, or was illiterately adjusted;
• the carburetor is contaminated;
• The air filter is very contaminated;
• The use of inappropriate fuel can cause a reduction in the gearbox revolutions;
• At idle, your trimmer for grass can stall if the throttle closed;
• Air fell into the carba system;
• The lawn mower receives a missing portion of gasoline to work fully, and therefore stalls.

Why is a trimmer not starting for grass gasoline? Reasons and their elimination

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 the trimmer for the grass does not start hot and even on cold.

Often, when reducing the speed, the motor motorcycles stalls and does not support idle speed when re.starting. The main reasons for the occurrence of such a breakdown include pollution or the dumping of the carburetor, as well as clogging of the air filter.

Gasoline trimmer for grass stalls at idle

In case of violation of the optimal settings of the carburetor, it is necessary to clean it and repeated adjustment. You can cope with clogging the air filter of a trimmer for grass by placing it for several hours in a solution with a conventional domestic detergent. If independent cleaning has not helped to cope with the blockage, it is better to purchase a new filter element in accordance with the operating manual.

After the measures, the user will not encounter a situation for a long time when a trimmer for grass stalls in idle and functions only when gas supplies.

A braid braid with a gasoline drive is a useful thing for owners of personal plots, lawns, and when a trimmer for grass suddenly stalls, the work on cleaning the territory stops from the grass. The device itself is a rather complex mechanism, so there are many different causes of its breakdowns.

At single speeds, the common reasons for stopping a trimmer for grass are as follows:

• reducing the speed of the gearbox when heating it, which is a consequence of the use of inappropriate fuel mixture;
• clogging of the throttle;

• air entering the system;
• not enough fuel for the operation of the lawn mower.

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

Subsequent work is likely on the carburetor:

• cleaning and adjustment of the fuel supply valve;
• similar work with a valve producing redesigned gases and pairs (after burning fuel);
• replacement of the spring more weak 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.

Immediately after the start

Smelting Motokos or a trimmer for the grass after starting is justified by subsequent reasons:

• impressive of previously adjusted valves;
• first the wrong settings of the valve mechanism;
• clogging with deposits of the fuel supply valve;
• the hose is worn or poorly annexed.

Due to the violated method of injection of a fuel, a lawn mower or a trimmer for grass is very vibrated in work.

When pressing gas

If the lawn mower stops when pressing the gas, then the reasons may be the following.

• The most common option is a fuss of adjusting the carburetor, which occurs with significant loads on the drive, after a prolonged inaction of the mechanism or when it is used in severe conditions.
• The clogging of the fuel valve, which eliminates it with the message, as a result of which gasoline according to the system begins to flow normally.
• The weakening and hanging of the cable in the carburetor. Also, a tensile of the fuel hose can occur up to its rupture, caused by the action of a significant load.
• Clogging of the saapun (check valve), as a result of which fuel does not enter the tank.

If the problem is associated with the carburetor node, then it can be recognized by the appearance of vibrations of the lawn mower. Когда лопается шланг или растягивается трос — выполняют замену данных комплектующих.

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 that extend 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.

About the reasons why the lawn mower stall when you press gas, watch in the next video.

The lawn mower does not develop speed.Another reason

The analogue of Husqvarnana develops the reason, the reason was very simple (watch in the video)

If you have done operations with the filter, but the work of a trimmer for grass working from gasoline remains the same, the benzotrimer does not gain momentum what to do?

Then you should try to extract the filter from the device in order to provide the so.called “relief” of the trimmer for grass. Why is a Chinese lawn mower not developing speed, the cause of Husqvarna. Should help.

The next and rather common problem when working with a gasoline trimmer is that it simply stalls and does not give any signs of life.

In this case, the problem may be as follows:

The last and most common cause of the breakdown of a gasoline trimmer for grass is that the cable that is located in the carburetor department was just sleeping.

Therefore, make sure that it will be well pulled, but not to the limit, otherwise with too much load on the gasoline trimmer for grass, this small cable can crack and then you will definitely have to contact the service center, and then also throw out many money into the wind.

The gasoline trimmer for grass stalls at idle

Often, when reducing the speed, the motor motorcycles stalls and does not support idle speed when re.starting. The main reasons for the occurrence of such a breakdown include pollution or the dumping of the carburetor, as well as clogging of the air filter.

Why stalls the lawn mower: reasons and solutions

The reason why your tool abruptly stops working, namely the engine does not gain revolutions, breaks them off, or “stalls” in popularity, there may be more than one. Often this is to blame not only the engine itself, but also the adjacent systems, unit nodes, completely different details related to the preparation of the fuel-air mixture, its quality, transportation to the tool of the tool. Consider the most typical situations:

• He is not gaining momentum. The engine drive mechanics may be damaged or there were problems with the carburetor, but the main reason should be considered clogging of the air filter. To change the situation, it must be removed, cleaned, and if it is no longer subject to the latter, then change for a new one, promptly making an order on our website. Also, there will not be a turn of the braid for grass, if the cable from the carburetor constantly flies. disassemble the unit and firmly fix it, or buy a new one if cracks are found on the element, other types of deformations.
• At high speeds. The lid on the gas tank is clogged. it needs to be cleaned or new. often the reason is a sipped carb. We submit information on the correct adjustment of all screws in information articles. Check the quality of the fuel hose and change it to a new one if necessary.
• When heated. It occurs in moments when the fuel in the carburetor literally boils. It can also appear in the options if the carba damper is more rare, rotary type (not disk). The only option would be to replace the carburetor with a new. There is another option for a broken wire or ignition coil. In this case, change the element of the latter.
• Starts and stalls (immediately after launch). Solved or incorrectly adjusted carburetor is the main reason for this situation. Calm vibration will indicate an uneven supply of fuel, and competent adjustment of the node will help to correct the situation.

We hope you found the right answer to the question: why the lawn mower stalls, and all the proposed catalog details today, as always, are at your service. You need a piston trimmer for grass, a new carburetor, or the elements accompanying the operation of these systems. you will find everything in the open spaces of the Benzo SIP store.

What to do if the lawn mower stalls when you press the gas

Most often during the periods when the lawn mower stalls when the gas is added, the cause will be the air damper, more precisely, its condition: it clogged. Structurally, the part is located in the place where the resulting fuel is sprayed behind it, and, accordingly, the product collects all inclusions in low.quality gasoline. To eliminate the problem, you just need to clean it. The same situation can occur with a filter clogged, but it is eliminated similarly. Total, we specify the reasons for which the tool is led to the gas to the stalled state:

• a clogged air damper;
• The clogged filter is fuel, and when you give gas, this is especially noticeable;
• the air of the crankshaft shaft occurs;
• damaged gasket between the cylinder and the carb.

When you cleared, washed and blowing the elements, but again the lawn mower stall when you press the gas-replace them with new ones, check the quality of the fuel, as well as the literacy of the proportions of the cooked mixture. When opening the air damper, the tool will stall for the following reasons:

• Dosage carburetor.
• The appearance of cracks on the fuel hose caused air leaks.
• The occurrence of problems with the oil seals.

In the process, there are situations when the lawn mower at high speeds is subject to a similar sharp stop. It occurs for the following reasons:

• due to problems with the circulation of the fuel mixture;
• with air leaks;
• The fuel intake hose is poorly connected or cracked and cannot be used;
• stab or clogged the valve of the cover of the gasoline tank;
• The carburetor was resolved.

In most cases, nevertheless, the cause will be a carburetor and related filter, hoses. If you need cutting gear or trimmer heads, then our site will also offer them to buy them with gasoline tools and components for them.

Features of diagnosis

A well.posed question is already half the answer. The fact that the gasoline trimmer for the grass or the lawn mower stalls, namely, will significantly accelerate the search for a solution

• immediately after the start;
• when it works for some time idle. after one or several minutes;
• when pressing the gas button (or handle). or shortly after the start of work at high, submasymal speeds;
• under an enhanced load (for example, to cut the bushes, mow thick and high weeds);
• when warming up in the cold, it heats out excessively (the lawn mower stalled around overheating);
• After the opening of the air damper.

Depending on which of the circumstances was clarified during the pre.diagram, the exclusion method is looking for a more specific reason for the malfunction of motorcycles or a trimmer for grass.

In the process of warming the engine

If the engine heats up too fast, overheating. a lawn mower or a trimmer for grass works unevenly, as if jerking. After which she stalls. The reason may be as follows:

• boiling gasoline;
• The ignition wire was damaged (poor insulation);
• The coil in the ignition system has noticeably burned out, inter.seal circuits appeared.

The same heating is observed when using rotary (not disk) damper.

With gazeaming

You click on gas. and the trimmer for the grass stops working, does not develop momentum. The following alleged reasons are possible:

• The tuning of the carburetor was lost, which appears with an increasing load on the drive itself. after its long downtime or when working in extreme conditions;
• The fuel valve is clogged with deposits;
• The carburetor cable is weakened and sag;
• Excessively stretched, possibly torn off the fuel supply hose;
• The check valve (sapun) clogged with deposits. fuel does not enter the tank with fuel.

Important! Problems in the carburetor itself give themselves out the vibration of the lawn mower

When working idle

Having launched a trimmer for grass or a motorcycle at idle, you find that the device is starting up. but it swallows, after working, say, 5-10 minutes. The reasons here may be as follows:

• clogging, violation of carburetor adjustment;
• Initially incorrect configuration of the valve mechanism of the carburetor;
• air filter clogging;
• reducing the speed of the gearbox (if any). the incorrect ratio of the fuel mixture;
• clogging the throttle;
• penetration of excess air into the fuel system;
• The fuel ends in the tank (and oil in the tank, if the engine is four.stroke).

If there are problems directly with the carburetor, the machine will stop both after a cold start and after launch on the already worked engine.

Checking performance

Before the diagnosis of Magneto, you need to make sure that the problem is actually in this node. To do this, check the entire chain and make sure that there are no other reasons for the breakdown of the trimmer for the grass.

• First, you should carefully examine the coil for the presence of cracks and other external defects on the case. Next, you will need to study all the elements and nodes conducting the current and make sure that they are clean.
• The next step is the inspection of high.voltage wires. They must be working and reliably attached to the contacts, without traces of rust and with intact insulation.
• The next action will be checking the candle cap. As a result of careless actions, the user often tears it off from the high.voltage wire, and then improvises and creates a home.made mount. You need to understand that any poor.quality connection in this place significantly reduces the power of the electric arc of the candle.
• Then you should make sure that the candle itself is working. If you refuel a low.quality motorcycle with gasoline, the service life of this part is significantly reduced. In addition, it can be flooded or have a large incapacitance that prevents work. Sometimes the candle even takes up and does not unsc.
• Next, you need to inspect the circuit switch. On trimmers and chainsaws of Chinese.made, it very often breaks.

Replacing the seals of the Chinese trimmer for grass.

One of the main causes of air leaks into the engine are crankshaft oil seals. In general, this problem is the most common on Chinese trimmers, and in some cases, seals begin to pass the air in the first year of service. All the fault of low.quality rubber products of such mowers, well, no one has canceled natural wear.

Essle for different sizes were installed on both sides of the crankshaft (12227mm small and 15307mm large). You can safely sin on the seals if it begins to “snot”. Another indicator of their malfunction is floating turnover when working for “hot”. Next, we will consider in detail the process of replacing.

Why does the car stall at idle and what to do?

Car owners often fall into a situation where the engine suddenly stalls. the car does not go or work at idle. From this article you will learn about the reasons for stopping the motor, diagnostic methods, repair methods

Diesel does not hold idle speed

To understand why the engine stops at idle, it is necessary to study the principle of operation of this system slightly. The diesel engine works as follows: under high pressure, the fuel is injected into the cylinder, while the air in the cylinder is compressed 16-25 times. High temperature helps to compress small particles of diesel fuel, from which these particles are ignited and the burning of diesel fuel occurs. Gases expand the piston, it falls down, that is, it makes reciprocating movements. The reasons for stopping the diesel engine at idle can be:

• not the intake of fuel in the fuel pump of high pressure;
• lack of a signal of the operation sensors of the position of the crankshaft entering the control unit.
• There is no way to regulate high pressure in the specified limits (the most common cause of engine stop).
• depressurization of a high.pressure system. the elements of the nozzle wear out and the fuel, which is dumped into the return, increases. It reaches volumes in which the system is not able to maintain the necessary pressure in the rail;
• mechanical wear of the parts of the high.pressure fuel engine;
• Docking in the internal pressure valve filter.

The stop of a classic engine operating on diesel fuel occurs for the same reasons as in modern engines.

For what reason does an electric braid for STIHL grass do not develop full power

When using an electric trimmer for the grass, non.aviation problems may also occur. Here the reasons are completely different than that of fuel cos.

You can eliminate problems yourself

Eletric trimmer for grass does not develop the required power, because:

• The voltage in the network is below the required minimum for the device more than 10%;
• There was a failure on a smooth launch (if there is such a system);
• there was a malfunction of the brush node;
• The engine winding was burned;
• rotating parts sometimes jamming.

To establish voltage, you should first check its power. If it does not meet the norms, it should be increased using a stabilizer.

The repair of the smooth start system is carried out only in the service center.

With wear of brushes, you just need to replace them. When installing new ones, it is recommended to clean all the surfaces with which they contact.

To establish voltage, you should first check the power.

When burning engine windings, you need to change the electric motor.

Jamming of parts of rotation can occur for various reasons. To eliminate them, you should review the entire drive unit.

The last problem may also arise in another unit of this company. the STIHL prisoner, and the sharpening of the disk on the scissors will be its solution.

Immediately after you started

The unit may stall immediately after starting, if the carburetor is shifted or incorrectly adjusted. This causes an uneven supply of fuel. As a result, the device vibrates clearly. To eliminate defects, the carburetor is reconfigured, following the annotations to the mechanism.

Apart from that, the engine stops when clogging the fuel supply valve. In such cases, it is quite easy to clean it. If the bureau at first earned, but later stalled immediately, then maybe the fuel with some difficulty falls into the carburetor knot. Weakening of the valve helps to solve the issue, which ensures free circulation of the consistency in the system.

The stop can also be caused by air leaks in the presence of mechanical damage to the hose (holes, cracks), taking fuel. In this case, increase the speed of the drive in order to resign more air from the system from the system.

Where to look for a reason or where to start checking

All chainsaws have the same design, and work according to one principle. The device of the chainsaw can be found in this material. It does not play much meaning which brand of the tool. Stihl, Husqvarna, Echo, Champion, Partner, Sturm and others. A malfunction manifested in the form when a chainsaw is stalling when pressed on gas can arise the same both on expensive and high.quality tools and on budget Chinese devices. If the problem has arisen, then it needs to be solved.

A chainsaw is a system of mechanisms consisting of details. Any detail in the mechanism can fail, which will lead to a partial or complete failure of the tool. If the tool engine starts, then this does not mean that the chainsaw is completely serviceable. Когда при повышении оборотов происходит прекращение работы двигателя, значит на то имеются соответствующие причины. With this malfunction, you need to pay attention initially to a number of the following tool mechanisms:

• Gas tank. make sure of the presence of fuel. If fuel is in sufficient quantity, you should also check the serviceability of the fuel filter, the presence of a connection of the supply hose with the carburetor, and also make sure that the operability

These are the main details and mechanisms that should be checked first if there is a malfunction when the chainsaw stalls when the accelerator is pressed. There are other reasons why the chainsaw engine stall when the gas trigger presses. What else can contribute to this malfunction, as well as features of elimination of breakdowns, we will find out later.
