Braid having petrol drive- This useful thing for owners personal plots, lawns, and when the trimmer suddenly stalls, the work of clearing the grass from the area stops. The device itself is a rather complex mechanism, so there are many different reasons for its breakdown. The most frequently encountered problems are contained in the operating instructions. You should know the reasons why the trimmer stalls in order to effectively repair the device yourself.

Problems with a lawn mower, related to the fact that this device does not start, are classified in a certain way by service specialists. They highlight faults with the following mechanism components:

• an engine in which the piston and bearings may wear out or fail, or the crankcase may crack;
• fuel supply system, in which case the filter may become clogged or problems with the carburetor;
• mechanical damage to wires, tubes, hoses;
• ignition circuit.

To correctly determine the unit where the breakdown occurred, you need to pay attention to the circumstances under which the trimmer stalls.

When you press the gas

If the lawn mower stops when you press the gas, the reasons may be as follows.

1. The most common option is carburetor adjustment failure, which occurs when there is significant load on the drive, after prolonged inactivity of the mechanism or when it is used in difficult conditions.
   
2. Fuel valve clogged, which is eliminated by relaxing it, as a result of which gasoline begins to flow normally through the system.
3. Looseness and hanging of the cable located in the carburetor. It may also occur fuel hose stretching up to its rupture, caused by the action of a significant load.
4. Breather clogged(check valve), as a result of which fuel does not flow into the tank.

If the problem is related to the carburetor unit, then it can be recognized by the appearance of vibrations from the lawn mower.. When a hose bursts or a cable stretches, these components are replaced.

Carburetor trimmer

At high speeds

When the scythe stalls at high speeds, this is due to the following problems:

• clogged or stuck valve located on the gas tank cap;
• the carburetor has become misregulated due to vibrations that occur during operation of the mechanism;
• circulation problems fuel mixture;
• atmospheric air suction;
• the fuel intake hose is cracked or loosely connected.

The carburetor is adjusted, relying on the operating instructions for the trimmer. To adjust it, it is often enough to loosen the tightening of its housing. If there are problems with the circulation of the fuel mixture, then it can gradually enter the carburetor. After it is exhausted, the engine stalls when high speed.

At idle

On idle speed Common reasons why the trimmer stops are:

• contamination, misadjustment or incorrectly adjusted carburetor adjustment;
• air filter clogged;

Replacing the air filter of a brush cutter

Trimmer air filter

• reduction in gearbox speed when it heats up, which is a consequence of using an unsuitable fuel mixture;
• throttle valve clogged;

• air entering the system;
• There is not enough fuel to operate the trimmer.

If the problem area is the carburetor, then the equipment will stop both during a “cold” and “hot” start.

Immediately after starting

The unit may stall immediately after starting if the carburetor is misadjusted or was incorrectly configured - this causes uneven fuel supply. The result of this is that the device begins to vibrate distinctly. To troubleshoot problems, the carburetor is reconfigured following the instructions for the mechanism.

Also the engine stops when valve clogged supplying fuel. In such cases, simply cleaning it is enough. If the lawn mower started working at first, but then immediately stalled, then perhaps fuel enters the carburetor unit with some difficulty. Loosening the valve helps solve the issue, which ensures free circulation of the mixture in the system.

The stop can also be called air leak in the presence of mechanical damage hose (holes, cracks) that collects fuel. In this case, you should increase the drive speed to quickly expel air bubbles from the system.

When heated

The brush cutter often stops when it gets hot. At the same time, it starts, works “with jerks” and gradually stops. This process happens when gasoline boils in the carburetor or the damper is installed in it of a rotary rather than a disk type. In the latter case, the part is changed.

It happens that the trimmer gets hot if Ignition wire is damaged or a coil. In order for the device to start working normally, parts are replaced.

When opening the air damper

It happens that the unit stalls when the air damper is opened, idling normally. This is due to air leaks from the system caused by the presence of cracked fuel hose or problems with seals. The carburetor metering system may also malfunction, and the lawn mower will stop after opening the damper.

All possible reasons why the lawn mower stalls and how to eliminate them are contained in the following video

There are many reasons why a lawn mower stops, but the most common are malfunctions associated with its carburetor. They can arise in any case. The most problematic option is when a serious breakdown occurs and you will need to purchase new parts or replace the lawn mower.

For the trimmer to work properly for a long time, you must strictly follow the instructions for use. It is necessary to refuel the unit with a fuel mixture suitable for its composition; the device must operate under moderate load.

Why does the chainsaw stall when I press the gas: premises and solution

There are often cases when owners of chainsaws are faced with their breakdown and it does not matter at all what model of this type of equipment, because the nature of breakdowns is almost the same for everyone. Well, the chainsaw has stalled, so what next? Of course, you can take the equipment to special services that will repair your “iron friend” for a fee. But as they say: why pay more?

After all, you can personally disassemble the tool and repair it, because the damage may be insignificant, but in the service you will pay a lot for it. The car stalls when you turn it on, press the gas pedal once, petrol trimmer?. But naturally, in order to bring a tool back to life yourself, you need to be able to understand the reasons for its breakdown and methods for eliminating defects. So let's educate ourselves! In this article you can find answers to questions regarding situations when the tool simply stalls after a specific press on the gas. So let's get started.

Basic elements of chainsaws

Before we begin to delve into the issues of tool breakdowns and repairs, let’s first understand what a chainsaw actually consists of. First, I would like to note that this tool belongs to the category of equipment whose operation directly depends on the gasoline engine.

It is also important that chainsaws are equipped with a single cylinder engine, and whose work is done on such fuel as gasoline. It should be noted that, despite the similarity with other tools, it does not have a gearbox. And it is replaced by a typical single-stage chain transmission, the means of which is the movement of the chain (saw) itself.

In fact, the chainsaw is quite conventional design, but this does not prevent it from being reliable, convenient and fully capable of ensuring specific uninterrupted and cyclic operation even in rather difficult conditions. This tool consists of a huge range of certain parts “vital” for its correct and productive operation. This is a carburetor, a specific chain tension device, a tire equipped with a chain and other elements.

Before purchasing a chainsaw, be sure to explore all the options and choose the brand of chainsaw that is right for you.

To make your choice easier, we have compiled a rating of chainsaws based on reliability.

If you have a limited budget, then read the article about Russian chainsaw manufacturers.

Characteristics and possible causes of failure. Fixing the problem yourself

Chainsaws are fairly reliable and lightweight designs. Therefore, if you properly care for them and handle them based on the manufacturer’s advice, then they fail very rarely and various types of breakdowns are quickly eliminated. But if you are faced with this situation and want to repair your own instrument yourself, without resorting to the help of experts, then delve into the information presented below.

In fact, it is impossible to clearly and accurately determine the reason why the tool does not start. or it stalls when you press the gas, because there are quite a few reasons that influence this. It starts up, idles for a while, or stalls itself, or when you press the gas, it also stalls. But we should not forget that, starting from the fact that the chainsaw is armed with a conventional two-stroke engine, such conditions as lubrication, fuel, spark and air are important for its effective performance.

Chainsaw fuel tank

As follows, it is the carburetor that produces the fuel-air mixture, the filter cleans the air from dust, the ignition unit and spark plug produce a spark, and the gasoline contains lubricant.

That is why it is necessary to search for the circumstances of this kind of breakdown in order, starting specifically from the easy ones and gradually moving on to the complex ones. And this is a fundamental factor proper repair, because the person who, without thinking it through, begins to disassemble the carburetor, brings her to risk. Because that kind the unit must be repaired or adjusted directly in special workshops(read about carburetor adjustment).

1. An important fact is that for trouble-free operation of the tool, it is necessary to be quite attentive to the fuel itself. Because at idle the trimmer stalls due to stihl chainsaw ms 180 stalls at. Since if this kind of mixture is not prepared correctly, then most chainsaws simply will not start. Consequently, not every owner will think to look for the cause of the breakdown in the fuel. That is why, in order for your tool to always work correctly, you need to use only high-quality gasoline for the mixture.

TRIMMER STIHL STALLS when you press the gas

TRIMMER petrol STIHL stalls when full throttle CAUSES DISEASES!

Benzonase trimmer Stalls when the throttle

Trimmer Petrol mower Stalls when adding gas. Trimmer doesn't pull. Trimmer loses momentum at load.

And also use only the oil that is made by the manufacturer of your tool. In addition, it is important to prepare this kind of mixture in the amount that you will definitely use in one or two weeks, but no more (see the proportion of gasoline and chainsaw oil).

Because otherwise, overexposure of the mixture directly in the canister will lead to it losing all its octane properties and this will lead to significant problems with the instrument.

The cause of the breakdown may also be a direct pouring the mixture into the candle at the moment when the mechanism is started. In order to solve this problem, you need to turn out and dry the candle, but remember that it should not be heated under any circumstances. Excess fuel must be drained through the hole (spark plug), wait 20-30 minutes, then put it back in place and try to start the tool again.

The chainsaw stalls when you press the gas because no spark. This can happen when there is no good contact between the tip of the spark plug and the wire (high voltage). However, if this kind of connection works correctly, but there is still no spark, then the ignition unit (electronic) is the cause. It is important to note that these types of spare parts cannot be repaired, so they can only be replaced.
Spark plug inspection

Do not forget that by examining the spark plug you can obtain significant information regarding the breakdown of the chainsaw. Since if its surface is dry, then the reason for this is the cylinder, into which fuel is not directly supplied. If the lawn mower stops when you press the gas, it runs at idle speed. That is why you will have to check the entire range of its supply step by step. If the spark plug is covered in black soot, this means that the carburetor is not working properly, that is, it supplies either a lot of fuel or pours oil directly into gasoline.

If the chainsaw stalls when adding gas, this means that fuel is supplied in insufficient quantities for full operation of the chainsaw. The reason for this may be either a clogged carburetor (its jet) or contamination of the filter itself (fuel). Remember that the first unit should be checked exclusively by professionals, but you can clean the second one yourself.

In addition, the cause of failure may be filter (air) if it is contaminated with dust. But do not forget that each model has its own easily removable and characteristic features. It is for this reason that do not hastily start disassembling and repairing the instrument, but it is best to “walk” through the forums, where there are a huge number of reviews from various owners, so as not to make things worse.

Since, for example, a calm chainsaw stalls when you press the gas for a simple reason, namely a simple clogging of the direct breather.

In order to solve this kind of problem, all you have to do is disconnect the (fuel) hose from the carburetor and pay attention to whether fuel is leaking out of it. Since if the mixture flows in a full stream, this means that the breather is not contaminated, but if on the contrary, then the cause of the breakdown has been found.

Here is another reason why a chainsaw stalls when you press the gas - muffler. It is this part that can interfere with the full operation of the tool in cases where it is directly contaminated with exhaust resinous deposits. To do this, you simply need to clean it.

Quite often the chainsaw partner stalls when pressed and the reason for this is cylinder-piston group. Since by examining them, namely the piston and cylinder, you can easily determine the cause of the tool malfunction by directly replacing them. You can also directly bore the cylinder itself relative to the dimensions of the new piston.
Chainsaw piston

But if after inspection you find that there is no damage on both the piston and the cylinder, then the reason may lie directly in the rings (piston). To the table of contents ^ causes of breakdowns and repair methods. If, for example, the tool stalls immediately after starting or does not start at all, then pay attention to the ignition system. To do this kind of check, you need to insert a piston into the cylinder and carefully begin to rock it using a connecting rod. If you suddenly feel play, then the rings need to be replaced, as they are already worn out.

Many people wonder: why does the chainsaw stall when I press the gas? The answer may also lie in insufficient chain lubrication(see chainsaw oil), since the oil line may be leaking, or the direct channels may simply be clogged. That is why pay attention to the chain, because if it is dry, then without delay, start cleaning the channels that supply oil directly to the tool tire. Then inspect in detail the parts where the oil pump fittings are connected to the pipes. But if you notice that oil is leaking at the joints, or you find cracks in the tubes themselves, then in the first case, seal the leaks with sealant, and the tubes will have to be replaced.

First of all, what you should remember when purchasing this kind of tool is that certain parts of the saw need to be replaced with new ones after their service life (passport) has expired. It is for this reason that the instructions should always be at your fingertips, since everything is described there in detail.

These types of details include: sprocket (drive), tire, part of the system (anti-vibration), as well as a chain. why does the lawn mower stall when you press the gas: reasons and (trimmer): - on hot. Since we should not forget that if this “filling” is not replaced with a new one at the required time, then these worn-out spare parts will negatively affect the remaining parts of the chainsaw. It is for this reason that check the depth of the immediate cutting of the teeth quite often. Remember that it should not be higher than 0.5 mm a week.

To sum it up...

Definitely, every item we buy has its own expiration date and sooner or later it breaks, and it becomes a shame when the degree of its breakdown is so great that it cannot be repaired. But you must admit that quite often we are simply negligent in our technology, and when it stops working, then we try to find ways to fix the breakdowns, contacting great amount services.

But remember that even though the equipment breaks down, we can extend its “life”. All you need to do is simply take care of it and keep its parts clean and tidy. And then, undoubtedly, it will serve for many more years. It is also important to use exclusively high-quality spare parts and “additives” (see attachments for chainsaws). Then your equipment will work smoothly, and you will simply forget what repairs are.

A petrol mower is one of the main tools of a summer resident, used to quickly put a plot of land in order. Owners of private houses also purchase this tool for mowing grass in their gardens. The period of active use of lawn mowers and electric trimmers occurs in the summer. Before using the tool, bring it into working condition: rubbing parts are lubricated, the cutting set is changed, the fuel mixture is poured into the tank. If the engine does not start at all or stalls quickly without gaining enough revolutions, then you have to look for the causes of the problems and eliminate the identified problems. To repair a lawn mower with your own hands, you need to understand its structure and the operating principle of its main components. This information can be found in the operating instructions supplied with the manufacturer garden equipment without fail. Check for such a manual when purchasing a chainsaw. An imported tool must be accompanied by instructions written in Russian.

A long tubular rod is attached to the gearbox two stroke engine internal combustion. Inside the rod there is a shaft that transmits torque from the gasoline engine to the cutting mechanism. The line or knives rotate at a speed of 10,000 to 13,000 rpm. IN protective housing The gearbox has holes into which lubricant is injected using a syringe. For ease of use of the tool, the manufacturer equips it with a special adjustable strap that is thrown over the shoulder.

The cutting accessories are included with the lawn mowers:

• The fishing line, the thickness of which varies from 1.6 to 3 mm, is located in the trimmer head. When mowing grass, the line wears out. Changing fishing line is done quickly and easily in two ways: by winding fishing line of the same diameter onto a spool, or by installing a new spool with already wound fishing line.
• Steel knives with double-sided sharpening for trimmers for clearing the area of ​​weeds, small bushes, and coarse grass. Knives differ in shape and number of cutting surfaces.

A U-shaped, D-shaped or T-shaped handle attached to the bar contains the trimmer control levers. The cutting mechanism is protected by a special casing. Household brush cutters are fueled with a mixture prepared from gasoline and oil, which is poured into fuel tank. Device for semi-professional and household lawn mowers equipped with four-fold gasoline engine, slightly different. The refueling scheme is also different: oil is poured into the crankcase, and gasoline into the tank.

The measured piece of fishing line is folded so that one end is 15 cm longer than the other. We insert the loop into the slot on the reel and begin to wind in the direction indicated by the arrow

What to do if the engine does not start?

If you cannot start the lawn mower, then the first thing you need to do is check the presence of fuel in the tank and its quality. To refuel the tool, it is recommended to use high-quality gasoline purchased at gas stations, the grade of which must be at least AI-92. Saving on cheap fuel can lead to breakdowns cylinder-piston group, the repair of which can take a third of the cost of the lawn mower itself. It is equally important to properly prepare the fuel mixture of gasoline and oil. The proportional ratio of these mixture components is indicated by the manufacturer in the manual. You should not prepare the fuel mixture in large volumes, as its properties are lost during long-term storage. It is better to use a freshly prepared mixture.

When preparing the fuel mixture, pour oil into gasoline using a medical syringe, which allows you to accurately maintain the required proportion of components.

A dirty fuel filter in the tank can also interfere with the operation of the trimmer's engine. Therefore, if you have problems starting the engine, check the condition of the filter. If necessary, replace the filter. Do not leave the inlet pipe without a fuel filter.

Also needs checking air filter. If the part becomes dirty, remove it field conditions washed in gasoline and put in place. At the dacha or at home, the filter can be washed in water using detergents. After this, the filter is rinsed, wrung out and dried. The dried filter is wetted a small amount oil used to prepare the fuel mixture. Excess oil is removed by squeezing the filter with your hands. The part is then installed in place. The removed cover is put back and secured with screws.

The air filter, washed in the fuel mixture, wrung out and dried, is installed in place in a plastic case and closed with a lid.

You can see how this procedure is done in more detail in the video:

If all of the above procedures have been carried out, but the engine does not start, then adjust its idle speed by tightening the carburetor screw. The video posted at the beginning of the article focuses on this issue.

So, in order:

1. Place the tool on its side so that the air filter is at the top. With this arrangement of the chainsaw, the fuel mixture reaches exactly the bottom of the carburetor. The engine will start on the first try if you remove the air filter before starting and pour a few drops of the mixture into the carburetor, then install the dismantled parts in place. The method has been tested in practice.
2. If the first tip does not work, then most likely the problem is in the spark plug. In this case, unscrew the spark plug and check its functionality, and also dry the combustion chamber. Replace a spark plug that shows no signs of life with a new one.
3. If the spark plug is in good condition, the filters are clean and the fuel mixture is fresh, then you can use in a universal way starting the engine. Close the carburetor choke and pull the starter handle once. Then open the throttle and pull the starter 2-3 more times. Repeat the procedure three to five times. The engine will definitely start.

Some people pull the handle so hard that they have to repair the lawnmower starter with their own hands. This is only possible if the cable breaks or the cable handle breaks. In other cases, it is recommended to replace the starter. This unit is sold assembled.

How to properly replace a spark plug?

The work order is as follows:

• Stop the engine and wait until it cools down.
• Disconnect the high voltage wire from the spark plug.
• Unscrew the part using a special key.
• Inspect the spark plug for replacement. The part is replaced if it is faulty, heavily soiled, or has a crack in the body.
• Check the gap between the electrodes. Its value should be 0.6 mm.
• Tighten the new spark plug inserted into the engine with a wrench.
• Complete the installation high voltage wire to the central electrode of the spark plug.

As you can see, there is nothing super complicated in this procedure.

New spark plug for two-stroke internal combustion engine gasoline spit is installed instead old part, out of order

Why does the lawn mower stall after starting?

After starting, the engine may stall if the carburetor is incorrectly configured or misadjusted. By what signs can we understand that the reason really lies in this? It’s very simple, based on the vibrations that will be clearly felt when the mower is operating. You can adjust the fuel supply yourself by following everything that is written in the operating instructions for the tool.

The engine may stall due to a clogged fuel valve. The cause can be eliminated by cleaning it. If the lawn mower starts up and then suddenly stalls, it means that the supply of fuel to the carburetor is obstructed. Loosen the carburetor valves to ensure free flow of fuel in the required quantity.

Excessive air leaks may also cause the engine to stall. Increase engine speed so that air bubbles leave the unit's fuel system faster. Also be sure to check the integrity of the fuel intake hose. If mechanical damage is detected (cracks, punctures, etc.), replace the part.

How to clean and store the instrument?

During operation of the lawn mower, monitor the condition of the engine cooling system. The channels in the starter housing, as well as the cylinder fins, must always be clean. If you ignore this requirement and continue to use the brush cutter, you can damage the engine due to overheating.

Proper care of a gasoline scythe during operation allows you to use it for several seasons in a row without major repairs.

Allow the engine to cool before cleaning. Take a soft bristle brush and scrub away any dirt. outer surface. Plastic parts are cleaned with solvents, including kerosene, or special detergents.

At the end of the summer season, the lawn mower must be prepared for long-term storage. To do this, the fuel mixture is drained from the tank. Then the engine is started to exhaust any remaining fuel in the carburetor. The entire instrument is thoroughly cleaned of dirt and sent to “hibernate.”

As you can see, you can repair malfunctions of a household lawn mower entirely on your own. You should contact service departments in case of serious breakdowns. In this case, you should compare the cost of repairs with the price of a new lawn mower. It may be better to buy a new tool.

In this article we will look at the problem why does a lawn mower stall and how to deal with this problem.

Even a very good brush cutter can have problems starting. For example, it starts and stalls. Most likely, this indicates problems with the filters - air or fuel. If it stalls at idle, then most likely the brush cutter has problems with the carburetor, which overheats too quickly and can no longer cope with the formation of a high-quality air-fuel mixture.

If the trimmer stalls when you press the gas, that is, when the engine starts to run at high speeds, then this indicates problems with the carburetor or fuel filter.

Problems with a lawn mower with an air filter will be indicated by the fact that it stops working when the air damper is opened.

Please note that the Well Part online store offers you for the most wide range and according to favorable prices.

What to do if the lawn mower starts and stalls?

Now let's look at all the problems described above in more detail.

1. The lawn mower stalls when you press the gas.

In principle, there can be a huge number of reasons why the engine of a brush cutter stops working when you press the gas. Here we will consider only the most common ones.

Perhaps the air damper is simply clogged. And to eliminate the problem, it will be enough to simply clean the air damper. Also, the engine stalls due to a clogged air filter. To clean it, the filter should first be washed in a solvent and then blown with a stream of compressed air.

A similar procedure should be carried out with a clogged fuel filter, which prevents the flow of fuel in the required volume when the engine speed increases.

The engine may stall for other reasons. Firstly, the spacer located between the cylinder and the carburetor has worn out, and secondly, the oil seals crankshaft started to suck in air.

2. The brush cutter stalls when it gets hot.

We have already indicated that in this case the problem is in the carburetor. Due to increased temperatures, gasoline begins to boil in it, which is why the air-fuel mixture ceases to form or its quality critically decreases.

Besides, this problem may occur due to the fact that the carburetor is equipped with a rotary valve rather than a disc valve. If the problem has become chronic, then it should be solved radically - by purchasing a new carburetor with a disc valve.

3. The brushcutter starts and stalls.

Most likely, access to the fuel tank is difficult or completely absent, which is why a zone of low pressure is formed in it, due to which the engine stops receiving fuel in required quantity and because of this you stop working.

4. The brush cutter stalls at idle speed.

The engine may stall at idle for the following reasons:

• Gearbox overheats

  got ready and began to prepare a not quite normal gasoline solution, which is why the speed on the drum began to drop;

• The carburetor is clogged;
• The carburetor is not adjusted correctly;
• The throttle valve is dirty;
• An open choke causes too much air to enter the carburetor, making the air-fuel mixture lean;
• The air filter is clogged.

To fix most problems you will need spare parts, and Well Part is ready to provide them to you at the best price.

What should I do if the trimmer stalls when I press the gas?

So, Why does the trimmer stall when you press the gas?? There may be several reasons for this problem.

1. The carburetor is out of adjustment after an unsuccessful winter or after too much intensive use brush cutters. Gasoline trimmer works on the air-fuel mixture, which is prepared for it by the carburetor. If adjusted incorrectly, this mechanism prepares a lean mixture, which is not capable of providing the engine with sufficiently high speeds. You can tell about a problem with the carburetor by the characteristic vibrations of the lawn mower.
2. You will know that the fuel filter is clogged by the fact that the trimmer starts and stalls. In other words, the flow of fuel is enough to start the lawn mower, but not enough to keep the engine running. It may be possible to solve the problem by loosening the valves on the filter. If not, you should wash the filter in solvents and blow it out compressed air. If after this the problem is not solved, then you should purchase a new fuel filter.
3. If the engine stalls at speeds close to maximum, then there may be a problem with the breather, which regulates the flow of air into the gas tank. When fuel is consumed too quickly, which is typical when you step on the gas, a rarefied pressure forms in the gas tank, which reduces the flow of fuel to the engine.
4. The engine stalls when the throttle is opened. The problem, again, is related to the carburetor, which, due to excess air, prepares a lean air-fuel mixture, which is not capable of ensuring engine operation.

Does your lawn mower stall when it's hot? There is a solution!

The lawn mower stalls when it is hot - this means that there is already a certain amount of fuel in the engine to start the engine, but after 5-10 minutes of operation, it stops working. This behavior of the engine indicates problems with the fuel filter.

A brush cutter is the most important tool for those who prefer to store their land in order and beauty. This type The equipment copes well with almost all types of grass and weeds. After using this device, a plot of land overgrown with weeds will look as it should.

However, any tool is subject to failure. Sooner or later, the lawn mower produces various types of malfunctions. How to solve emerging problems with gasoline scythes will be discussed in this material.

1 The most common causes of failure of lawn mowers

Obviously, the more reputable the manufacturer, the more reliable his products are often - this is the most main criterion determining the reliability of an ordinary buyer. The second criterion can be called cost, the third - reviews of owners who have tested the operation of the tool in their own practice. By the way, high cost often does not mean high quality, durability and resistance to breakage. It is better to conduct a more detailed market analysis before buying a lawn mower, and then choose the “golden mean”.

Before we move on to the list of the most common causes of mower breakdowns, we note that very often inexperienced owners of lawn mowers do not know, for example, what ratio of gasoline to oil should be poured into the fuel tank, what kind of gasoline is best to add to the device, how much oil to pour into gasoline and so on.

Some also do not know what lubricant to use for the gearbox, how to sharpen the disk or knife, and many other nuances. Due to these and other reasons, unfortunately, in large quantities cases and breakdowns occur various equipment, including trimmers and gasoline mowers. Users simply do not take proper care of their equipment.

However, there are a number of the most common reasons that arise as a result of the specifics of the functions performed and other external and internal factors that lead to breakdowns:

• The cutting cord does not feed or breaks too quickly. This occurs due to the lack of fishing line, or the cutting line has become tangled in the reel;
• the engine does not start. Inexperienced users are not always able to start the unit the first time due to the “Start” button being turned off. But there are other factors: clogged air filter; the spark plug gap is not set, or it is out of service; a gasoline carburetor can often overfill the fuel mixture; insufficient amount of fuel has been pumped;
• Often, lawn mowers do not develop speed, which can be caused by four factors: a clogged air filter, a clogged shaft with a cutting reel with mowed grass, an incorrectly adjusted carburetor, or bad fuel poured into the tank;
• the engine does not idle. If the engine itself is working properly, but stalls at idle, then there may be three reasons: a clogged air supply filter; the carburetor is not adjusted; bad gasoline or lawn mower oil is used;
• Also, a problem such as lack of spark occurs regularly. Reasons: bad blockage, broken spark plug, faulty or oxidized contacts of the supply armor line.

In addition to the listed most discussed breakdowns of gasoline mowers and the reasons for their occurrence, you can find a lot of other complaints and reviews about this tool on the Internet. However, how to solve the problems listed above is the subject of the next chapter.

1.1 Troubleshooting methods

Cord breakage occurs regardless of the quality of fishing line in the reel. To correct this problem, it is enough to rewind the cord into a reel if it is tangled, or wind a new one if it is missing.

How to start a lawn mower if the engine does not start? Check whether the Start button is turned on, whether the oil is pumped sufficiently with the supply button, and whether gasoline is poured into the tank. If the engine still does not start, wash the gas filter (sometimes it should be replaced if a large blockage is detected), check the spark plug for functionality, and clean the air filter.

It did not help? Adjust the carburetor choke to position C, this solves the problem of fuel overflow. If the engine is stubborn, simply drain all the fuel from the system and fill in new fuel, making sure that it has proper quality. Carrying out all these processes solves the problem of starting the engine in 80-90% of cases.

If the engine refuses to idle, first adjust the carburetor and wash the air filter of the device - this solves the problem in most cases. If the situation repeats, then most likely you poured bad fuel into the fuel tank, then drain it and fill the tank with new one.

How to start a lawn mower and make it work if the engine speed does not pick up and it stalls? First, check to see if the cutting shaft is clogged with grass and weed waste. If everything is fine with the shaft, wash the air filter or replace it with a new one if the first one seems too dirty to you. By the way, you should wash the air supply filter detergent and gasoline, which makes the gasket more elastic and prevents the material from drying out.

If, after completing these procedures and pressing the starter for the lawn mower, the lawn mower stalls again, then the problem lies in an incorrectly adjusted carburetor device. Read the last section of this article, it tells how to adjust the carburetor on a lawn mower.

If there is no spark, install a spare spark plug to check what exactly is wrong. When the spare spark plug also does not produce a spark when setting the correct gap, then the problem is with the scythe equipment. Repairing a lawn mower in the event of a malfunction begins with checking the wire leading to the spark plug.

Clean the contacts, you can also clean the contacts of all nearby wires, make sure that all wires are intact. After completing these steps, pressing the starter button on the lawn mower should result in a spark appearing at the spark plug. Remember that when testing a spark, the spark plug must be in contact with a metal surface to create an electrical mass. We emphasize that the reduction in speed (engine damping) is often affected by contamination of the lawn mower gearbox.

2 Carburetor adjustment

This aspect is always needed when setting up a lawn mower. A properly tuned carburetor is the key successful work engines for lawn mowers.

Despite the fact that the question of how to adjust the carburetor on a lawn mower seems incomprehensible to beginners, repairing a lawn mower often ends with this procedure, since the reasons lie in incorrect adjustment, and the repair of a lawn mower and how to eliminate them are included in the setup procedures. By the way, running in a lawn mower also involves adjusting the carburetor part.

To understand How to properly set up a gasoline carburetor for a lawn mower, you need to know:

1. The device contains three screws: right (L), bottom (T), left (H).
2. A correctly configured carburetor idles evenly and without fluctuations when the engine is cold and hot, as well as during a sharp descent or increase in speed. Screw T is responsible for idling.
3. Screw L is responsible for how much fuel mixture will enter the combustion chamber at low speeds. When adjusting, the screw is turned counterclockwise a quarter turn.
4. Fuel adjustment at high speeds occurs via screw H. To adjust, apply full throttle by opening the throttle. Turn the screw clockwise until you hear the RPM drop. Then turn the screw to reverse side so that the engine runs unevenly, then begin to slowly turn the screw again clockwise until you begin to hear a smooth and uninterrupted operation motor.

The correctness of the adjustment is determined even by the color of the working part of the candle. If the carburetor is adjusted correctly, the spark plug will be clean and free of carbon deposits.

For a 2-stroke unit, 2-stroke engine oil must be used.

2.1 How to sharpen a knife or disk for a lawn mower?

To sharpen a blade or mowing blade, know that good disc or the knife must be sharpened so that the edges become sharp, but the metal is not overheated. Sharpened cutting element will ensure easier removal of the grass surface. Also, the sharpness of the disc or knife affects the number of plants that will be removed with one grip.

In general, servicing a gasoline scythe involves constant cleaning of the equipment after work, checking the quality of oils and gasoline, as well as a properly adjusted carburetor. Do not put questionable additives or the like into your lawn mower. Regularly lubricate the gearbox and lubricate the moving elements to prevent problems. It is recommended to renew the lubricant at least every 1000 operating hours.

Before you figure out why any of the tools of a gardener or a professional working with a lawn mower stall, it is worth distinguishing between two main situations when this happens. The first is when the tool does not start after you have just made the purchase, and the second is when it is in operation. So, let's look at both.

1. After launch. The lawn mower stalls if the carburetor is configured incorrectly or is misaligned. Fuel is supplied unevenly, and accordingly, distinct vibrations occur.
2. When heated. A situation when the mechanism starts up and works, but gradually “chokes” and stalls while driving - when gasoline boils in the carburetor, or the damper in the carburetor is not a disk type, but a rotary one. In such cases, it is better to replace the carburetor itself. There is an option for air leaks - when the coil or wire in the ignition is broken.
3. At high speeds. This also occurs from a misaligned carburetor or a clogged cap on the gas tank. It is worth trying to work with the valve slightly open. Be sure to check the fuel intake hose - it may be cracked or poorly attached to the base.
4. Not gaining momentum. The main reason why the engine does not pick up speed is a clogged air filter. It is possible that the cable in the carburetor may fall off, the carburetor may break down, and problems may arise with the mechanics of the engine drive.

There are times when a mechanism part requires mandatory replacement, so we are always happy to offer. It is important to understand that sometimes saving on minor elements can lead to the breakdown of such global components as a carburetor or engine. Therefore, proper operation and timely replacement of the necessary particles will ensure you full-fledged work with pleasure.

The lawn mower stalls when you press the gas, how to fix the problem

Reasons why the brush cutter stalls– there can be a huge number, we offer the most common of them, and we hope that you will find yours and, of course, eliminate it. So, one of the situations is a clogged air damper, the hole behind which fuel is sprayed. If something gets into it, it can most often be quickly and easily removed. This is the simplest reason, just like a clogged filter. It needs to be washed in a solvent and then blown well with compressed air. If it cannot be repaired, then order a new one in spare parts from the KosiKosa store.

Likewise, when you press the gas, the tool stalls because the drive is clogged. The following option is also possible: the fuel does not enter in full, so you need to check or replace the fuel filter. Other possible reasons for a lawn mower stalling when you give it gas include:

1. The crankshaft seals suck in air;
2. The spacer that is located between the carburetor and the cylinder in a “problematic” situation;

To all these reasons why the mechanism stalls when gas is added, we will add a few useful recommendations on handling a brush cutter. First of all, before starting to work with any equipment, you need to read the instructions. In this case important role The consistency of gasoline and oil plays a role, it is properly prepared by you, and also do not overheat the unit, and do not leave gasoline for the winter when you simply will not use the car.

In the full operation of any instrument, the coordinated work of all its components plays an important role. And if in one it is this, then in the other there is a piston or a carburetor. Owners of brush cutters who want to use their tools to their full potential need to understand that under a load for which the machine’s capabilities are not designed, the entire mechanism or its individual parts may simply break. Therefore, only competent and moderate operation presupposes long-term effective operation of any gas-powered tool.

The trimmer stalls at idle - causes and solutions

To common situations, why trimmer stalls or brushcutter, it is worth considering its operation at idle speed. Let's get straight to the reasons:

• heating of the gearbox and a decrease in speed on the drum as a result of the fact that the gasoline solution is not prepared quite correctly. The required proportion is 1:4;
• carburetor contamination;
• the throttle valve is clogged;
• when the damper is opened (if such an experiment was carried out), the air flow makes the mixture “lean”;
• carburetor adjustment;
• air filter clogged;

An insufficient amount of fuel, which is needed for the operation of a gas-powered tool, will lead to a situation where at high speeds, when increasing, the trimmer works, but stalls at idle. In a situation with a carburetor, the device will stall on a cold start and on a hot start. For any user of a lawn mower - professional or amateur - it is important to understand that any problem with the tool may depend on a minor part coming off, a fastener coming off or clogging, as well as a global breakdown of an important part of the mechanism.

Despite all sorts of problems, your device still needs such an essential component as, without which the operation of the scythe is simply impossible!

Those who have lawns on personal plot, they know that a trimmer is a rather useful thing that will help you quickly and efficiently tidy up or clear weeds from a heavily overgrown area. And, like any mechanism, it also often fails due to various breakdowns. One of the most common complaints from device owners is that the trimmer stalls when pressing the gas. We propose to understand the main reasons for this phenomenon and identify ways to solve the problem.

Why does the trimmer stall when you press the gas?

1. Unfortunately, a situation in which the engine stalls when you press the trimmer gas can occur in many cases. Most often, the “culprit” of the problem is the carburetor. This is the most common reason why the trimmer stalls. As a rule, troubles occur when the carburetor is misadjusted, which is possible after long-term storage, after operation in adverse conditions, heavy loads on the engine. It is easy to recognize the “fault” of the carburetor by the appearance of vibrating movements of the trimmer. If you have experience repairing a car carburetor, it makes sense to try to repair it yourself using the owner's manual. Although it is much safer to give the part for repair to professionals at a service center.
2. Another reason why the trimmer stalls when you give gas may be a clog in the fuel valve, which interferes with the normal fuel supply. It is easy to solve the problem by loosening the valves, after which normal delivery of gasoline to the carburetor is possible.
3. If a similar problem arises, you should pay attention to check valve- breather Located in the gas tank, the check valve prevents a vacuum from forming in the tank. If the breather is contaminated, air does not flow, as a result of which the fuel supply stops.
4. Often, without gaining momentum, the trimmer stalls under heavy load. This happens if the cable located in the carburetor is weakened and hanging down. It also happens that an over-tensioned fuel intake hose stretches greatly under load, cracks and eventually bursts. If such a problem occurs, you will have to replace this component.

As you can see, there are many reasons why the trimmer may stall when you press the gas. That is why it is important to monitor the condition of your assistant and timely check the condition of all mechanism systems.

Causes and repairs

Sometime in early June, I began to notice that my GT22GES trimmer (manufactured by ECHO) began to lose its former power.

During work when cutting grass, even with slight magnification loads (the grass is taller and thicker), the speed dropped and the work efficiency was no longer what it was before.

Previously, the trimmer did not notice such obstacles at all. When I sharply pressed the trigger without load, the speed increased slowly, as if reluctantly.

I took the user manual for the trimmer and found the “Faults and Troubleshooting” section in it. I selected a suitable malfunction in the table, which is described something like this: “The engine accelerates poorly or fades out.”

Among possible reasons- dirty air filter, fuel filter, clogged fuel tank drain hole, spark plug, carburetor, clogged cooling system, clogged exhaust channel or muffler.

As it turns out, the list of possible reasons is extensive – where to start?

First I looked visually at the air filter, drain hole, air radiator, all this turned out to be in normal condition.

Then I decided to look from the end of the list, that is, check the exhaust system - exhaust duct and muffler.

To do this, I removed the spark plug tip, unscrewed 3 screws and removed the plastic protective cover of the muffler (in the drawing in the Manual under No. 15). Then, unscrewing two long screws, I carefully removed the muffler, so as not to damage the two gaskets that are present there.

My premonition did not deceive me. The exhaust channel of the engine cylinder (through which exhaust gases exit the cylinder) was 30 - 40 percent clogged with carbon deposits.

So this was the reason for the malfunction of my trimmer!

This is what the exhaust channel looks like

Carefully, so as not to damage the surface of the piston and to prevent foreign products (in other words, that same carbon deposit) from entering the cylinder, I completely cleared the exhaust channel of carbon deposits and carefully blew out the channel using a pump.

I used a knife as a tool (but only at the edge of the channel), and in the depths of the channel, a wooden and plastic spatula of suitable sizes.

The muffler turned out to be quite clean both inside and out.

After assembly, I started the trimmer, warmed it up a little and tried to mow - the engine started working like new, the power increased noticeably, it didn’t actually mow the grass, but chopped it (3 mm fishing line).

It’s nice that the device began to work perfectly and it’s doubly nice that I was able to find the problem myself and fix it.

It is likely that this problem can arise in other models of trimmers, because they all have approximately the same design and all trimmers have an exhaust duct and a muffler.

To understand this, you need to know the operating principle of the unit as a whole. It also happens that a new saw that has just been purchased does not start, and running around begins. service centers, in such cases it is recommended:

Reasons for the malfunction of the lawn mower:

The quality of gasoline is poor;
incorrect proportion of gasoline and oil;
filter clogged fine cleaning;
the spark is gone.

Petrol mower won't start after winter

In such cases, the unit must be serviced. Take off fuel system, including filters (air, fuel), disassemble the carburetor, clean and rinse each unit. Blow out the filters with air. Pay attention to the quality and octane number of the fuel.

It must be taken into account that products such famous companies like STIHL, Husgvarna and other brands, will not work on cheap low-octane gasoline.
For them, suitable fuel is from the AI ​​brand - 92 and higher from car gas stations, and even then from well-established ones, since gas stations also have bad gasoline. The use of high-octane and high-quality gasoline will determine how long the lawn mower will be used and how long it will last.

One more fact must be taken into account that when a diluted fuel mixture is stored for a long time, its performance decreases, which also leads to consequences in which the lawn mower does not start. Therefore, it should be diluted in portions, that is, the amount of mixture that is produced at a time.
The operating instructions clearly describe and explain the mixing ratio of gasoline and oil. Strict compliance correct proportions At a minimum, it will save you from several questions about why the lawn mower won’t start and what to do in such cases.

The lawn mower starts and stalls. What to do?

1. There is a spark, and everything seems to be normal, but the lawn mower does not start; in such cases, you should check the air access valve into the fuel tank. A clogged valve leads to the creation of a vacuum in the tank, in which the carburetor does not receive enough gasoline, so the lawn mower will start, but then stall. To eliminate this cause, you need to clean the valve and try to start the lawn mower with the tank cap not fully tightened.
2. If the lawn mower does not start, you should remove and clean the fuel filter, and also check all carburetor parts, and then try to start it. The mower won’t start again, the air filter is disconnected, try starting it without it, if the mower starts up, the reason is in the air filter, replace it.

The lawn mower won't start, no spark

Loss of spark entails checking the contacts and the correctness of the gap between them, the conductive wire to the spark plug and the spark plug itself.
The way to check the spark is to unscrew the spark plug, connect the wire to it, place the spark plug sideways on the engine casing and pull the starter several times as if starting a lawn mower, while looking at the coal and the contact of the spark plug, a spark should run between them.
If there is no spark, take a new spark plug and do the same procedure; if even then there is no spark, then the problem is in the wire or contacts, it is better to replace them.

Petrol mower won't start when cold

When starting a cold engine, it is not recommended to press the gas. Having tilted the lawn mower so that the air filter is on top, press the fuel suction button 5-6 times, set the function switch lever to the “start” position, pull the starter cord several times until the engine starts. After a few seconds of engine operation, turn off the starting system.

The lawn mower does not start when hot

If the lawn mower has recently been in operation and has not yet had time to cool down but does not want to start, press the gas trigger, sharply pull the starter cord several times until the engine starts and only then release the gas trigger. If enough time has passed and the lawn mower has had time to cool down, then you need to start it as if it were cold.
If the methods described above did not help, and the lawn mower does not start, then you should contact a service center.
