Trimmer for grass Elitek stalls at large speeds. STIHL trimmer stalls when pressing gas

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.

Asseting device and common malfunctions

The easiest way to give the lawn mower for repairs, allocating a certain amount of funds from the family budget, operational and high.quality repair with your own hands is no less simple and convenient to understand the design of the lawn mower and fix all the problems.

The massive and piece manufacture of trimmers is based on the use of generally accepted technology, the typical design scheme consists of certain elements and parts, it is important to know them when carrying out independent repair work:

• top part. The basis of the entire structure, where all important elements are collected, such as the starter, carburetor and the engine of the lawn mower;
• middle part. Hollow rod, inside it is a cable connecting the engine and gearbox, which sets the cutting fishing line for the trimmer. In this part there are mounts for the distribution of weight of the entire structure and a belt for fixing a trimmer for grass on a belt of a person using a trimmer for grass for its intended purpose;
• Bottom part. It has a gearbox and cutting elements that are hidden under a practical casing, which protects the user. The casing provides an increased level of safety, preventing large fractions of garbage, pebbles and glass in a person while working with a gas station.

The most common and often encountered, subject to independent correction of the breakdown of the unit can be called the following problems:

• engine malfunction, due to which the lawn mower is not started and does not work;
• enhanced vibration of the bar motorcosa, which complicates its targeted use;
• increased overheating of the gearbox, its accelerated heating during operation;
• slow and weak functioning of the cutting fishing line at insufficient speeds;
• the clogging of the starter grill causing the engine overheating and its refusal to work;
• rapid and frequent clogging of the carburetor due to the use of poor.quality fuel;
• clogging of the air filter in case of non.compliance with measures to care for the device.

All these problems can lead to the fact that the device will lose its ability to work before ordering the necessary spare parts for non.bosomeds should be carried out by a visual inspection and diagnosis of the device.

Special attention is required by individual spare parts and assemblies of the device, to verify them, you will not have to turn to a professional master, a complex of diagnostic measures will help to identify a consequence of the occurrence of a loss of performance.

The lawn mower stalls

When purchasing a lawn mower, you need to be prepared for the fact that, as in all other similar tools, it may also have breakdowns that will require repairs.

However, do not immediately run to the service center and pay a lot of money to the masters who convince you of a serious malfunction in the device.

The lawn mower stalls at high speeds

Perhaps the most common complaint related to gasoline trimmers sounds like this: “The lawn mower stalls”.

Of course, the reason for this may be a rather serious malfunction. However, most often the situation is much simpler than it seems at first glance.

To cope with such a problem, first of all, try to deal with its causes on your own, because, having found out the reason, it is much easier to fight the problem, and sometimes it is even self.destructive.

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

Another, this is the presence of malfunctions in the power system.

In this case, the lawn mower will stall at idle. The problems with the power system may lead to a drainage or incorrect carburetor adjustment.

Vibrations that take place in the process of operation of the lawn mower can lead to a reservoir.

Incorrect adjustment of the lawn mower can be fixed by simply adjusting it in accordance with the requirements specified in the operating instructions.

In addition, sometimes gasoline trimmers for grass can stall due to the fact that the valve located in the gas tank lid just clogged or sticks.

To find out, try using a braid by loosening the gas tank cover.

If in this mode the device works properly, clean the valve.

over, the lawn mower can stall due to poor fuel flow into the carburetor

Why then the device starts up, ask you?

The reason for this is that at first the fuel gradually falls into the carburetor and is enough for work with increased power.

However, then it is produced and at large speeds the engine begins to stall.

As for the carburetor, here the problem may also be that its body is too pulled.

The reason that the lawn mower stalls at high gas speeds may also be an air leak.

We are talking about the possible presence of a place through which air can pass during the heating process of the engine.

Among other things, do not forget to check the fuel intake hose. The problem may be that it is weak or cracked at all.

These are the main reasons why the gas mowl can stall.

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.

Check the fuel pump relay

often there is a breakdown of a tanosa relay. To check it, you need to turn the ignition lock on a broken engine. A click should be heard in the relay area, and the operation of the gasoline pump will begin within a few seconds. If there is a click, but the pump does not work, perhaps contacts are burned in the relay. This can be checked by an oh.energized relay and after supply to its voltage winding 12 V with the battery terminals. Obstrated contacts should show infinity, and closed. resistance in a fraction of OM. If the relay is regular, you need to check the connection of the mass to the gasoline pump.

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.

Immediately after you started

The unit can stall immediately after the launch, if the carburetor is cesspool or was incorrectly configured. this causes Uneven fuel supply

The result is that the device begins to vibrate clearly. To eliminate problems, the carburetor is reconfigured, acting according to the instructions for the mechanism.

The engine also stops when Clotting of the valve

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

The stop may also be called Air suction

In the presence of mechanical damage to the hose (holes, cracks) that fuel fuel fuel. In this case, the drive should be added to the drive to quickly drive air bubbles from the system.

When opening an air damper

It happens that the unit stalls when opening an air damper, working normally at idle. This is due to the air leaks of the system caused by the presence Cracks of the fuel hose

or problems with seals. The carburetor dosing system can also work malfunctioning, while the lawn mower will stop after the opening of the damper.

All possible reasons that the lawn mower stalls, and the methods of eliminating them are contained in the next video

There are many reasons for stopping Motokos, but the most commonly occur in work related to its carburetor. They can arise in any case. The most problematic option is when there is a serious breakdown, and you will need to purchase new parts or change the lawn mower.

So that the trimmer for the grass works normally for a long time, you should strictly comply with the requirements of the operating instructions. It is necessary to refuel the unit suitable for it in the composition with a fuel mixture, the device should work with a moderate load.

At high speeds

When a braid for grass stalls at high speeds, this is due to the following problems:

• clogging or clutching a valve located on the gas tank lid;
• The carburetor was diluted under the influence of vibrations arising during the operation of the mechanism;
• problems with the circulation of the fuel mixture;
• atmospheric air
• The hose intended for fuel fuel cracked or slightly connected.

The carburetor is regulated by relying on the operational instruction to the trimmer. For configuration, it is often enough to weaken the tightening of its body. If there are problematic issues with the circulation of the fuel mixture, then it can gradually enter the carburetor. After its production, the engine stalls at high speeds.

Malfunctions leading to improper operation of the chainsaw

There are a number of malfunctions that must be taken into account in diagnosis, t. to. They can lead to the interruptions of the saw.

• Damage to the crankshaft bearings. With worn crankshaft bearings, the appearance of a beating on the main shaft is inevitable, where the flywheel is attached. In such a situation, it is impossible to adjust the gap between the flywheel and the ignition coil, which entails interruptions in sparking, and unstable work of the chainsaw.
• Pollution of the pulse channel. The pulse channel serves to ensure the operation of the fuel pump, respectively, its pollution leads to improper operation of the pump, which will make it impossible to operate the saw (it will be launched and immediately stall).
• Wear of the CPG. As a rule, with increased wear of CPH, a decrease in compression in the chainsaw engine is observed, which is necessarily affecting its ability to develop momentum.
• Fuel and air filters pollution.

At high speeds

When a braid for grass stalls at high speeds, this is due to the following problems:

• clogging or clutching a valve located on the gas tank lid;
• The carburetor was diluted under the influence of vibrations arising during the operation of the mechanism;
• problems with the circulation of the fuel mixture;
• atmospheric air
• The hose intended for fuel fuel cracked or slightly connected.

The carburetor is regulated by relying on the operational instruction to the trimmer. For configuration, it is often enough to weaken the tightening of its body. If there are problematic issues with the circulation of the fuel mixture, then it can gradually enter the carburetor. After its production, the engine stalls at high speeds.

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.

Why stalls the lawn mower | Benzotrimmer | when pressing gas ? We solve this problem /al-ko FRS 4125

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.

If you stalled when heated

The lawn mower often stalls when heated. It looks like this. the tool starts, works “jerking” (not smoothly) and stalls quickly. This situation occurs due to boiling of fuel in a carburetor or incorrectly selected damper, which should not be disk, but rotary. In the latter case, if an error is detected, the part must be replaced.

The reason for heating the trimmer for the grass may be damaged ignition circuit or faulty coil. The broken node will need to be replaced with a new.

Restoring the performance of electrical equipment

Mowers, inside of which electric motors are located, most often begin to be capricious due to oxidation of contacts. The terminals are covered with a layer of scale from excess humidity in the room or in another place of storage. It is also worth checking the absence of a break in wires in problem areas. For this operation, a multimeter or other tester type is used.

When a set of garden equipment contains a brush engine, we identify the performance. Brushes can wear out quickly, leading to a lack of contact. The reptity of them costs relatively little, and it is easy to find it in specialized stores, where they sell spare parts for such a technique.

Asynchronous engines are also in wait for the malfunctions. They refuse phase.drive capacitors. A similar situation is diagnosed at home is problematic. It can be detected by indirect symptoms:

• The sound of a buzz is heard;
• When starting, the case twitches slightly;
• significant heating of the motor occurs even at a slight load;
• Reduces are reduced.

It is worth diagnosing the condition on the tolerance/button and the voltage supply to the electric motor.

Then you will have to use the services of the corporate service.

At high speeds

The hole in the fuel cover (saepun) of a trimmer for grass

With a similar problem, it is worth paying attention to the fuel valve, which, when clogging, ceases to normally pass the fuel mixture. By solving this malfunction, it is weakening using a suitable tool. In addition, the problem with the circulation of the fuel mixture may cover in the contamination of the valve. To do this, just blow it with a stream of compressed air.

• etching of atmospheric air into the combustion chamber;
• problems with the circulation of a mixture of fuel;
• clogging the saapun in the lid of the fuel tank (cleaning the hole with a thin sewing needle);
• Incorrect carburetor adjustment.

When air sunses, when I operate ICE, it is necessary to check the tightness of the pipes and the integrity of the gaskets in the CPG. The problem with the circulation of the fuel mixture can be solved by the elimination of blockages in the fuel pipes leading to the carburetor. If a vacuum occurs in the tank and not receipt of the fuel mixture to the carburetor, it is enough to clean the soundtress with a thin needle and blow it with air.

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.

When a braid for grass stalls at high speeds, this is due to the following problems:

• clogging or clutching a valve located on the gas tank lid;
• The carburetor was diluted under the influence of vibrations arising during the operation of the mechanism;
• problems with the circulation of the fuel mixture;
• atmospheric air
• The hose intended for fuel fuel cracked or slightly connected.

The carburetor is regulated by relying on the operational instruction to the trimmer. For configuration, it is often enough to weaken the tightening of its body. If there are problematic issues with the circulation of the fuel mixture, then it can gradually enter the carburetor. After its production, the engine stalls at high speeds.

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.

• 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.

The gasoline trimmer for the grass stalls when you press the gas

Why is the chainsaw stall when you press the gas?

Hello! If you are on this page, then, apparently, your chainsaw stalls when pressing gas, and you want to know why this is happening and what to do with it.

Why does the lawn mower stall after starting? And Husqvarna sins. As a result, when pressing gas.

Well, I will try to help you with this problem, having examined the most common reasons for such an adversity, as well as methods for their elimination.

To begin with, I will immediately write for new users that many chainsaws before work requires the engine heating at idle for about one minute. Until the engine is heated, the saw can stall when gas is added.

So, if a heated chainsaw can work at idle, but stalls at a load, this means that:

• The carburetor is incorrectly configured or clogged. the most common case;
• She lacks air, the consumption of which increases sharply with an increase in revolutions. this means that the air filter is contaminated (the case is rare, since the filter pollution occurs gradually, so the user first notices power loss);
• She lacks fuel, the consumption of which also increases with an increase in revolutions. this means that the fuel filter (also an infrequent case) is contaminated;
• Well, the most unpleasant case, if there is excessive friction between the piston and the cylinder wall associated with the lack of oil in the fuel mixture. after such a chainsaw you are most likely, you will fly to the repair of the piston group, since bunches that prevent the piston and walls of the cylinder that impede the piston and walls of the cylinder work of saws.

Little oil in the fuel mixture

First we will analyze the most unpleasant case. Why? Because before you do manipulations with filters, it is better to make sure that your oil and gasoline are mixed in the correct ratio.

Here, however, it is worth noting that if your drank was already repeatedly (for ten times) has been opened by you, but continues to start, and then stall again with increasing speed, then with fuel, apparently everything is in order. Otherwise, she would just stop starting at all.

But still, I recommend that I immediately dispel the slightest doubts about the quality of the fuel, as soon as I drank you stalled when the revolutions for the first time.

Because if the cause is in fuel, then, as already mentioned above, you can get to expensive repairs. And so, it can still do.

Dispel doubts is to drain the old fuel from the tank and pour freshly prepared, in which oil and gasoline are mixed in the correct proportion.

The correct ratio is better to watch in the instructions for the saw. If you are lost, then we look at the ratio on the oil packaging. Usually it happens 1:50 or 1:40. If the oil is used “non.native” (well, for example, for the stihl “native” there will also be few Stihl), I recommend using a 1:40 proportion, even if 1:50 is written on the packaging with oil.

Trimmer for grass The lawn mower stalls when adding gas / Benzonase Trimmer Stalls When The Throttle

trimmer for grass The lawn mower stalls when gas added. trimmer for grass does not pull. Trimmer for grass loses momentum at load.

For an accurate dosage, I personally use a medical syringe and a measured capacity in which one liter of gasoline can clearly measure. I pour a liter of gasoline into a container, type in a syringe 25 (at 1:40) or 20 (at 1:50) oil cubes and add it to gasoline.

After preparing a new mixture, drain the previous mixture from the tank, in which we are insecure, and fill the freshly cooked.

Now that you have done everything to dispel any doubts about the quality of fuel, we proceed to further actions.

As I already wrote above, with a lack of oil on the piston and walls of the cylinder, scuffs can form. and almost always form. If you are lucky, and the bullys did not appear, then with a new fuel mixture prepared in the correct ratio, the chainsaw should begin to work normally.

If the bullying appeared, then the saw can start and stall several times, after which it will stop starting up. In such a situation, I sympathize with you, since, most likely, now you will need to make a replacement for a piston group that will cost a lot.

If the saw, as before, starts and stalls at high speeds, then we carry out manipulations with filters.

The air filter is contaminated

Moving in the contamination of the air filter is quite easy. You just need to remove it and start a chainsaw without it. if the saw works normally, then then the matter is in it and it just needs to be changed or washed, depending on its type. And do not be afraid that the chainsaw will work for a while without protection against dust. if there is no dust cloud around you, then everything is in order.

So, remove the air filter. Husqvarna ”and“ Stihl ”and ending with a click on gas, stalls on. To do this, you need to remove the lid from the back of the chainsaw, which is attached either with screws, or just with some kind of fixer that you just need to turn or jerk off.

If when the filter is removed after the drain, the saw works normally, then it means it is contaminated.

Air filter is felt or nylon. The first resembles cotton wool or synthetic winterizer, and the second looks like a small mesh of nylon threads stretched on a plastic case. The gasoline trimmer for the grass does not start? Reasons and solutions on the example of Elitech T750. The felt should be changed to a new one, but the nylon can simply be washed in soapy water, dried and put in place.

Well, then we calmly use the chainsaw.

The fuel filter is contaminated

If the option with an air filter did not suit you, then try to change the fuel. It is located in a gas tank and attached to the hose through which fuel is taken from the tank.

Any tool is able to break and the stihl ms 180 chainsaw is not an exception. Today we’ll try to understand such issues as: why the chainsaw stalls with increasing speed, as well as at idle and at full. Consider the options for diagnosing and eliminating faults associated with this behavior of the Stihl 180 chainsaw.

Why is the chainsaw stall when you press the gas

Suppose a chainsaw work normally at idle, but with a sharp press on the gas stalls. What could be the reason? It is immediately clear that the matter is not in the ignition (lack of spark), t. to. If the ignition is malfunction and the lack of a spark, the tool would simply not start. So the fuel system remains.

There are a lot of malfunctions of the fuel system and to determine the exact reason why the Stihl 180 chainsaw is stalling when the gas is pressed, it is necessary to carry out its full diagnosis. We recommend reading about the common malfunctions of the Stihl 180 chainsaw and their elimination.

Checking the filter

The first thing you need to check is the fuel filter.

In some cases, a filter clogged with dirt, it is unable to pass through the fuel mixture through sufficient quantities.

Accordingly, a deficiency of fuel occurs in the system, which leads to the fact that when pressing the gas is pressed, the fuel burns out, and the new one still does not have time to act as a result of which the Stihl chainsaw is stalling.

Also, with a clogged fuel filter, there may be a noticeable drop in the power of the chainsaw at maximum speed, but this is with slight contamination.

Air filter

On the pages of the World Wide Web, you can find information that the chainsaw of the Stihl 180 can stall due to severe air filter pollution.

I would like to refute this not entirely correct information, and report that the STIHL carburetor MS 180 is equipped with a compensator, which is designed and installed in order to make the air of the STIHL 180 chainsaw, bypassing the contaminated air filter.

Of course, the power with a clogged air filter will fall a little, but it will definitely not stall. Another capacity may fall due to the wear of the piston, here the repair of the piston chainsaw of the Stihl MS 180 will already be required.

Carburetor

One of the reasons why the chainsaw does not develop momentum when pressing gas, but on the contrary, stall, these are malfunctions of the carburetor. Suppose the STIHL 180 saw worked properly, and then it was put for a long time and did not use it.

After it was brought up, and it works well on idle, and when you press the gas, it can stall. Why stalls? The reason for the sticking valve-comps of the carburetor. Of course, this is not 100%, but the probability of such a malfunction is high.

We recommend reading an article about the device and repair of the STIHL 180 carburetor.

In order to check the nozzle, you need to remove the carburetor and disassemble it. To remove, it is necessary to unscrew two nuts of fastening of the air filter and carburetor, and then remove the air filter and the engine control lever, disconnecting the air damper control traction from the carburetor. Next, you need to pull the carburetor a little on yourself, and disconnect the fuel supply hose.

Having removed the carburetor, it needs to be blown and cleaned of dirt, only after that the carburetor can be promoted.

It is necessary to promote the cover of the main camera of the carburetor, this is the one on which a compensator is installed on top. Further with a bolt by 8 mm and a length of at least 50 mm. We knock out the valve.

After the nozzle is removed, you can blow it with a compressor. The valve must pass air in only one direction, if you can freely blow the valve in both directions, then it is faulty and it is necessary to replace it with a new. Assemble a chainsaw after the valve is repaired, it is necessary in compliance with the reverse sequence of disassembly.

Look clearly how the carburetor repair is repair, or rather how to correct the valve record from the carburetor case, you can watch the video.

Another frequent reason why the saw can stall with an increase in revolutions, air leaks to the carburetor.

It is possible to check this only by having a special tool, but it is worth noting that if preventive work with the carburetor has not been carried out for a long time, then you can install a new set of gaskets in the carburetor. In some cases, this helps to solve the problem with its depressurization.

Disassembled the carburetor to replace the gaskets, you need to carefully inspect its needle valve, press the rocker and control its raising.

Sometimes, especially after the stihl chainsaw stood for a long time with fuel in the carburetor, the needle can burn to the carburetor body and not perform its functions.

Simply put, the needle valve will not pass the fuel mixture. In this case, the saw will not work.

Why stalls idle

The first and most common cause of this malfunction is the wrong carburetor adjustment. You can adjust the idle speed yourself, for this you need to have a STIHL adjustment screwdriver, which comes with the unit. The adjusting hole is located on the right side of the STIHL 180 saw on the handle and is indicated by the symbols “-” and “”.

If the Stihl chainsaw does not hold turns and stalls at idle, you can almost 90% be sure that it has violations in the system of the fuel pump, as a rule, it is an air leak into the crankcase through the lining of the pallet, or, much more often, through the seals crankshaft. The air leaks reduces or even completely stops the impulse, which is supplied through special channels to the fuel pump of the chainsaw. As a result of this, the Stihl 180 chainsaw does not receive the required amount of fuel and stalls at idle.

Diagnose, you can use a special device called a vacuummeter.
