The forward of the forward stalls when you gas. The trimmer stalls for grass at idle – the causes and their solutions

Why does a trimmer for grass stall at idle

If the lawn mower stops when pressing the gas, then the prerequisites may be subsequent.

• The more increased option is a carburetor adjustment failure that appears with significant load loads after a long.term inaction of the mechanism or when using it in languid criteria.
• The clogging of the fuel valve, which relieve it with a 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. There may also be a stretch of the fuel hose right to its gap, caused by the action of a significant load.
• The clogging of the soundtress (revolutionary valve), as a result of which fuel does not enter the tank.

If the inconsistent is associated with the carburetor node, then it can be recognized by the appearance of vibrations of the lawn mower. When the hose bursts or the cable stretches, the devices are replaced.

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 could break

Malfunctions with a benzocosa associated with the fact that this device is not started, in a certain way are classified by specialists of service services. They stand out malfunctions with the following nodes of the mechanism:

• the engine in which the piston and bearings can be worn out or fail to crack the crankcase;
• the fuel supply system, while it is possible to clog the filter or problems with the carburetor;
• mechanical damage to wires, tubes, hoses;
• The ignition chain.

To correctly determine the knot where the breakdown occurred, it is necessary to pay attention to the circumstances of the trimmer stalls for the grass.

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.

Not starting a chainsaw on hot

There are no unnecessary phrases in the operating instructions, everything that is proposed is aimed at the trouble.free operation of the lawn mower. Cleaning all parts after each cycle of work contributes to the light removal of not hardened residues and dirt. You need to clean only cooled nodes. This technique contributes to the quality of the air cooling of the engine and the gearbox.

For refueling, it is necessary to use fuel with oil recommended in the instructions. If you leave the combustible mixture in the fuel tank, the oil will float and dies on the damper when starting, worsening its adjustment. The mixture can give a sediment and score fuel supply in the carburetor.

When preserving equipment for the winter, make an audit, grease the gearbox and the piston system, wrap the entire saw in the oiled rags and store in a dry place.

Carburetor adjustment and configuration

The maximum and minimum engine speeds, even idle is regulated by the carburetor. The stable operation of the lawn mower depends on the amount of fuel mixture and air. The lawn mower is not started with disturbed adjustment of the carburetor. The procedure for setting up the device for supplying fuel at low speeds (L), high speeds (H) and idle (T) is regulated by the same vints:

• The chainsaw should work for at least 10 minutes, since the adjustment is carried out in hot.
• The screw n is flooded smoothly to maximum speed, then turning on ¼, counterclockwise, reducing the speed of rotation of the engine shaft.
• The idle stroke is regulated by the screw T, ensuring that the braid for the grass does not rotate.
• The screw l is regulated, first opening the throttle as much as possible, and then smoothly reducing the speed to stable minimum.

After adjustment, a proper carburetor with cleaned filters should ensure the operation of the engine. In the event of a malfunction of the carburetor, after its repair, it will again need to configure the supply system before starting the lawn mower.

Rare breakdowns that prevent the operation of the lawn mower can be:

The most important malfunction, the elimination of which is associated with the replacement of the engine may be the failure of the piston group of the engine. The cost of repair will cost about 70% of the cost of the product. To figure out the reasons why the lawn mower is not starting up will help

The gasoline trimmer for the grass starts and 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. 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.

A trimmer does not start for the grass for cold reasons

To begin with, we will analyze the situation when it is impossible to start the engine of the lawn mower to a cold. What does this mean? Surely Kosari came across a situation where a trimmer for grass starts on hot just perfectly, but you just have to make a short break, as the problem arises. This problem with the start of the engine after it cools. What could be the reason? Of course, no one excluded all the above factors, but if the situation is constantly found, then there is no need to check them. If a hot lawn mower starts well, and problems arise on the cold, then you should look for the reasons inside the CPH (cylinder-piston group).

To identify a malfunction, you will need to use a compressometer. We screw the compressometer into the hole instead of a candle, and after that we drive the starter handle. Measure the pressure inside the cylinder. compression. The amount of compression should be at the level of about 8-12 atmospheres. After the tool has warmed up (it is enough to work for 15-20 minutes), you should repeat the verification procedure. If the compression on the hot engine is below 8 atmospheres, then the CPH fault is appropriate. This means that the rings, the piston and the walls of the cylinder are worn out.

You can fix the situation by replacing CPG

When replacing it, it is important to take into account such a recommendation as abundant smearing of parts with motor oil inside the cylinder. This is necessary so that in the first minutes of starting a new cylinder with the piston, no formation of

With a decrease in engine compression, fuel consumption increases, and the productivity of the tool falls. You can work with such a tool, however, with each subsequent hour of work, wear increases. One day, the lawn mower will not be completely launched even with warming up.

It is interesting! You can warm up the engine of the lawn mower with low compression by pulling the starter handle. When warming up, the metal is expanded, thereby the compression increases.

Problems in electronics

In a modern car, all the processes that occur in the engine are controlled by a special computer computer. This system independently selects optimal modes and the ratio of gasoline and air in the fuel mixture.

For the mixture to be prepared correctly, the ECU collects data from a large number of sensors. So, if the car stalls when you press the gas (injector), then the throttle position sensor could fail, DMRV or coolant temperature. Determine whether sensors work correctly, you can use special diagnostic devices.

The trimmer for grass stalls. how to eliminate the problem

A gasoline trimmer for grass is a useful tool for cleaning from unnecessary grass of house territories and large area lawns. The design of this technique is quite complicated, therefore, if the device breaks, there may be several reasons. The most likely factors that have caught a breakdown are usually described in the user guide. Knowing why a trimmer for grass stalls, you can try to independently eliminate the defect. The most common malfunctions provoking the motorcycle stops, and the ability to repair them with your own hands is in the material further.

In order to most accurately determine the cause of the trimmer malfunction for grass of any brand (for example, echo) and find out the possibility of eliminating it, you need to install, when performing what action the device stalls. The engine can turn off both at idle and at high speeds, heated under load or immediately after starting and t.D.

If you stalled after gas supply

Owners of gasoline braids often mention that the lawn mower stalls when you press the gas. Usually such a breakdown occurs due to problems in the carburetor. A failure in his work can occur due to long-term storage, use in difficult conditions, significant overload of the motor. The symptom of such a breakdown will be vibrating movements of the device during operation.

On a note! Users familiar with the repair of a car carburetor can try to restore this important node of the trimmer for the grass on their own, using the instructions for operating. Otherwise, the correct decision will be to seek help from the service center representatives.

Sometimes a trimmer for grass stalls when you give gas because the fuel valve is clogged. This interferes with the supply of gasoline. To eliminate the problem, it is enough to loosen the valve. Thus, normal supply of carburetor fuel will be restored.

Another possible reason why the lawn mower stalls when gas is supplied is pollution of the soundtress (check valve). This detail prevents the appearance of a vacuum in a gas tank. If it is clogged, the air does not flow, which means that fuel does not go to the carburetor. To eliminate the problem, it is necessary to clean this element.

If it stalled at high speeds

If the carburetor stalls at high speeds, this means that in idle and small there are enough incoming fuel, and to work on high is not enough. Then it is necessary to check the serviceability of the following nodes of the trimmer for the grass.

• Fuel hose. its integrity could be violated as a result of cracking. In this case, you need to replace the part. Or maybe you just need to tighten the clamps.
• A filter network between a carburetor and a hose for supplying a gasoline mixture-it could clog. In this situation, it is necessary to clean the detail.
• The valve on the gas tank cover. he could stick or clog with garbage. Cleaning is also necessary.
• Carburetor. perhaps as a result of constant vibration, it was resolved. This is usually characteristic of cheap Chinese details. To eliminate the problem, it is necessary to set up according to the instructions. In some cases, it is enough to only weaken the tightening of the carburetor case. If the adjustment is not possible, it is necessary to install a new element.
• Additionally, check the air filter. Perhaps it will need to be washed and cleaned or replaced with a new one, as he could clog with dirt and particles of grass when tilted technology, when the user mowed in hard.to.reach places.

If you stalled during work idle

If the lawn mower stalls, working idle, there may be several factors reasons.

• First you need to check the prepared fuel solution, when it comes to a four-stroke trimmer working on a gasoline-oil mixture. There is a chance that it is made incorrectly. the proportions are not withstanded. Because of this, the gearbox is warming up, and the revolutions on the drum are lowering.
• Another probable cause is blockage of elements such as a throttle, air filter or carburetor. You need to clean the indicated details.
• Another possible factor is to resolve or incorrectly carried out carburetor adjustment. You need to adjust the setting according to the instructions.
• Observe this problem mono and when opening the air damper. In this situation, the lack of fuel for a trimmer for grass occurs through the fault of the air flow.

If the device does not have enough fuel, it works properly at high speeds or when they increase, but stalls at idle. If the root of the problem consists in the carburetor, the lawn mower will be disconnected both with cold startup and hot.

If you stalled after starting

If the technique starts and stalls immediately after starting, this indicates the wrong settings or deducting the device. As a result of this, the fuel enters the engine unevenly, which leads to significant vibration and disconnecting the trimmer for the grass. To fix the breakdown, it is necessary to reconfigure the device according to the user management.

Another probable problem is the blockage of the valve supplying the gasoline mixture. It must be cleaned.

On a note! If the trimmer for the grass starts, but immediately stalls, it may also mean that the fuel is moving to the carburetor with difficulty. Weakening the valve will help to eliminate the problem. this will provide uniform and free circulation of fuel in the device.

Another possible reason is the damaged fuel intake hose. Air can penetrate through cracks and holes into the system. To solve the problem, you need to increase the engine speed in order to get rid of air bubbles that have penetrated the device.

If you stalled when opening the damper

If the technique works properly at idle, but stalls when opening an air damper, this reports about the penetration of air into the system through cracks in the fuel supply hose or damaged oil seals. To fix the breakdown and establish the work of the tool without driving air from the atmosphere, it is necessary to replace damaged parts.

Preventive measures and operating rules

So that the lawn mower does not work and does not stall when starting, it must be correctly stored and operated. Compliance with the following simple recommendations will forget about problems.

• When begging the grass, you need to monitor the state of the cooling system. It is also necessary to regularly clean the channels in the case and starter’s ribs.
• To clean the tool, you should use kerosene, solvent, or other washing tools.
• You can not clean a hot tool. it must cool before washing.
• It is important to observe the recommended working mode. this will avoid overheating of the engine.
• If a braid for grass is not used over the next thirty days, the fuel must be drained, otherwise it will fall into heavy components that can score the channels of the carburetor.
• After the fuel is merged, the trimmer for the grass should work at idle for some time until it turns off. This will allow you to completely get rid of the rest inside the working mixture.

To store the tool in cold weather, you need:

• completely drain the fuel;
• disassemble the lawn mower, wash and clean all available components;

• inspect the condition of the parts, eliminate all defects that can be corrected;
• pour the required amount of oil into the gearbox;
• Clean the air filter;
• perform partial disassembly of the engine, wash all moving parts, blow and lubricate thoroughly;
• To lubricate the piston, unscrew the candle, then raise the piston to the upper dead point by the starter, pour a small amount of oil into the hole for the candle and do the crankshaft several times.

Important! If there is no way to store a trimmer for grass in a warm dry room, you must first wrap the motor with an embarrassed rag.

Only by observing these rules, you can be sure that the lawn mower will work properly and will not stall for a number of seasons.

As you can see, stopping the work of a trimmer for grass can be caused by many reasons. Most of them can be fixed independently using the user instructions. In cases where there is no self.confidence, the equipment is recommended to be attributed to repairs. It is worth remembering that incorrect actions can cause even greater harm to the trimmer. As a result, the repair of Motokos will cost a much larger amount than it would be initially, and in the worst case, it may be necessary to buy a new unit.

What to do if the engine does not start?

If the lawn mower fails is not possible, then the first thing is to check the presence of fuel in the tank and its quality. For refueling the tool, it is recommended to use high-quality gasoline purchased at gas stations, the brand of which should not be lower than the AI-92. Savings on cheap fuel can lead to a breakdown of the cylinder-piston group, for the repair of which a third of the cost of Motokosa itself can take. It is equally important and correctly preparing a fuel mixture of gasoline and oil. The proportional ratio of these components of the mixture is indicated by the manufacturer in the manual. Do not prepare the fuel mixture in large volumes, since during long storage its properties are lost. It is better to use a freshly prepared mixture.

When preparing the fuel mixture, pour the oil into gasoline using a medical syringe that allows you to accurately comply with the necessary proportion of the components

Fuel filter pollution in the tank may also prevent the operation of the lawn mower engine. Therefore, when problems with the launch of the motor, check the condition of the filter. If necessary, replace the filter. It is forbidden to leave the incoming pipe without a fuel filter.

The air filter also needs to be in the test. During contamination, the part is removed, in the field is washed in gasoline and put in place. In the country or at home, the filter can be washed in water using detergents. After that, the filter rinses, squeezes and dries. The dried filter is moistened with a small amount of oil used to prepare the fuel mixture. Excess oils are removed by compressing the filter with hands. Then the part is installed in place. The removed cover is placed back and fixed with screws.

The air filter washed in the fuel mixture, squeezed and dried, is installed in place in the plastic case and covered with a lid

How this procedure is done in more detail you can look at

If all of the above procedures are carried out, and the engine is not started, then adjust its revolutions at idle, twisting the carburetor screw. In the video posted at the beginning of the article, attention is paid to this issue.

• Put the tool on the side so that the air filter is at the top. With this location of the chainsaw, the fuel mixture is ensured exactly into the bottom of the carburetor. On the first attempt, the engine will start if you remove the air filter before starting and pour a few drops of the mixture into the carburetor, and then install the dismantled parts to the place. The method is tested in practice.
• If the first advice does not give a result, then, most likely, the problem in the spark plug. In this case, unscrew the candle and check its performance, as well as dry the combustion chamber. A candle that does not show signs of life, replace the new.
• If the spark plug is in good condition, the filters are clean and fuel mixture, then you can use the universal way of starting the engine. Close the carburetor air damper and pull the starter handle once. Then open the damper and pull the starter 2-3 times. Repeat the procedure from three to five times. The engine will surely start.

Some pull the pen with such force that it is necessary to repair the starter of the lawn mowed with their own hands. This is possible only in the case of a gust of a cable or breakdown of the cable handle. In other cases, it is recommended to replace the starter. This node is sold in the collection.

Carburetor adjustment and configuration

The maximum and minimum engine speeds, even idle is regulated by the carburetor. The stable operation of the lawn mower depends on the amount of fuel mixture and air. The lawn mower is not started with disturbed adjustment of the carburetor. The procedure for setting up the device for supplying fuel at low speeds (L), high speeds (H) and idle (T) is regulated by the same vints:

• The chainsaw should work for at least 10 minutes, since the adjustment is carried out in hot.
• The screw n is flooded smoothly to maximum speed, then turning on ¼, counterclockwise, reducing the speed of rotation of the engine shaft.
• The idle stroke is regulated by the screw T, ensuring that the braid for the grass does not rotate.
• The screw l is regulated, first opening the throttle as much as possible, and then smoothly reducing the speed to stable minimum.

After adjustment, a proper carburetor with cleaned filters should ensure the operation of the engine. In the event of a malfunction of the carburetor, after its repair, it will again need to configure the supply system before starting the lawn mower.

Rare breakdowns that prevent the operation of the lawn mower can be:

The most important malfunction, the elimination of which is associated with the replacement of the engine may be the failure of the piston group of the engine. Why does a lawn mower or a lawn mower stall when you press gas, at idle, when heated and other causes of non.taxes of a gasoline trimmer for grass. The cost of repair will cost about 70% of the cost of the product. The lawn mower stalls or a trimmer for STIHL grass stalls when why Chinese. To figure out the reasons why the lawn mower is not starting up will help

What in the end

It is worth noting that the inconsistency of the idle move on the engine with the injector is diagnosed by the method of checking the main systems that are responsible for the flow of air in the internal combustion engine, also a change in the composition of the consistency, taking into account the number of incoming air. It turns out that it should also be taken into account that the failure of individual sensors of the ESUD can lead to an increase or floating turnover of xx.

The lawn mower stalls at high speeds

Perhaps a more common complaint associated with gasoline trimmers sounds like this: the lawn mower stalls.

Naturally, a rather formidable malfunction may be a prerequisite for this. How to adjust the carburetor at idle does not work. On the Forward Boistorose, even at idle (the benzotrimmer shaft always turns even on. The lawn mower stalls at idle. The Benzotrimmer system and the lawn mower system does not work. But almost always the situation is even easier than it seems in the 1st look.

To cope with such an inconsistency, at first, try to deal with its causes without the help of others, because, having found out the reason, it’s even easier to fight with the inconsistency, and at times it is even self.destructive.

In fact, events are when the lawn mower stalls at high speeds, there are quite a lot of these events.

Another is the presence of flaws in the power system.

In this case, the lawn mower will stall at idle. For what reasons Stihl 100 eighty stalls idle or complete gas at least some kind of tool can break and the Stihl MS 100 chainsaw is not an exception. The lawn mower does not work at idle. The problems with the power system may lead to a drainage or incorrect carburetor adjustment.

If the chainsaw of STIHL MS 100 eighty stalls at idle, does not gain power when pressed on gas or completely stalled at full speed, you need to diagnose the fuel system and inspect the crankcase for density. You can do this without the help of others, but you need to have certain abilities. If you are not familiar with two.stroke saws, it is better to turn to specialists, t. To. This technique is quite capricious and any errors are expensive.

The lawn mower stalls at high speeds

Perhaps a more common complaint associated with gasoline trimmers sounds like this: the lawn mower stalls.

Naturally, a rather formidable malfunction may be a prerequisite for this. I can’t get a trimmer for grass why when working a motor for but saw, with all this, it does not revolve? It works only when it is worth opening its trimmer for the grass does not work right away. On the suction. It works only when opening an air damper for one mm I do not think that a trimmer for grass but. But almost always the situation is even easier than it seems in the 1st look.

To cope with such an inconsistency, at first, try to deal with its causes without the help of others, because, having found out the reason, it’s even easier to fight with the inconsistency, and at times it is even self.destructive.

In fact, events are when the lawn mower stalls at huge turns, there are quite a lot of these events.

Another is the presence of flaws in the power system.

In this case, the lawn mower will stall at idle. Works only at idle. trimmer for grass actually new. This may be exclusively in case I can’t start a trimmer for grass Craton works on a sucker. Stalls, mm for two. And she doesn’t work. If the engine at idle why the motor works. The problems with the power system may lead to a drainage or incorrect carburetor adjustment.

Why does the lawn mower stall when you press the gas: the causes and their solutions. The lawn mower stalls (trimmer for grass): on idle.

• Idle sensor failure;
• Clogging of the throttle;
• The failure of the throttle position sensor;
• Injector or carburetor pollution

The grounds for breakdown can be completely different, therefore, when eliminating them, it will be necessary to operate with all kinds of actions and techniques. If your shoulders are considerable driver’s experience, and you know the features of the car’s work as your five fingers, regardless of the model, then the elimination of this kind of malfunctions will not cause you any problems. And all because such breakdowns are not complex or serious. It follows that you can establish the operation of the car without outside help. Well, if the level of awareness or lack of free time will not give you the opportunity to eliminate all defects yourself, it is better to seek help from knowledgeable people who can save you from unpleasant moments in the shortest possible time.

Why the lawn mower is not started, we eliminate problems

When caring for a personal plot, summer residents at times are faced with the fact that the lawn mower is not started. There are many circumstances of the instrument failure. A trimmer for STIHL grass is poorly started. For proper diagnosis of interference, the owner of useful in the country’s divetor should know the device and mechanism of operation of its individual parts.

Since the gasoline trimmer for grass refers to complex devices, before work you need to closely study the annotation for operation. Very often it is simply ignored, or they get acquainted with it superficially. As a result, when the tool stalls or renounces the question, the question arises. “why the lawn mower is not started

?»A long seasonal break in work, improper storage and untimely maintenance of a trimmer for grass, will deliver a lot of trouble to the summer resident, to eliminate the reasons.

Additional tips

First of all, what you should remember when acquiring this kind of tool is that certain details of the saw must be changed to new ones after their service life (passport) is over. It is for this reason that the instruction should always be at your hand, since everything is described in detail there in detail.

Such details include: asterisk (leading), tire, part of the system (anti.vibration), as well as a chain. Since do not forget that if this “filling” is not changed at a new time, then these worn spare parts will negatively affect the rest of the chainsaw. It is for this reason that quite often make a check of the depth of direct production of teeth. Remember that it should not be higher than a week 0.5 mm.

Muffler, as the reason that the saw stalls at the load

Here is another reason why the chainsaw stalls when pressing the gas. muffler. It is this part that can interfere with the full operation of the tool in cases where it is contaminated with directly exhaust resinent sediments. To do this, you just just need to clean it on.
