What is the gasoline gasoline from what stalls. Motor

The causes of breakdowns of gasoline and electric trimmers

Trammer for grass, both electric and with an internal combustion engine (ICE), is an indispensable tool in the summer and autumn period for owners of cottages and private houses. With its help, weeds, small shrubs are easily removed and the lawn is trimmed. But, like any technique, trimmers for grass fail at the most inopportune moment. To eliminate the malfunctions with your own hands, the user of this technique first needs to determine the reason for their appearance.

In the lawn mower and an electric trimmer for grass, if you do not consider breakdowns associated with the bar and the mowing head, the malfunctions mainly happen in the engine area.

Damage of gasoline trimmers

Typical breakdowns of a gasoline trimmer for grass, which are most often faced with the owners of this unit, are as follows:

• engine breakdown;
• problems with the carburetor;
• problems with the supply of fuel;
• muffler malfunction;
• gearal breakdown;
• The starter broke;
• Air filter problems;
• Broken a buckshot on a gas tank.

Malfunctions of electric trimmers

Since the device of an electric coser is much easier than a motirmer, then there are few reasons for its failure.

It should be noted that the elimination of some of them is best entrusted to the specialist.

Basically, the trimmer for the grass ceases to work normally in the following cases:

• Electric cable malfunction;
• The control button is faulty;
• burned engine winding;
• Contact joints break on the engine.

Why is the gasoline trimmer not starting for the grass

The reasons why the gasoline trimmer for the grass stopped starting is different, therefore, a phased diagnosis of the apparatus is required.

Fuel tank (fuel quality)

Remember that always before starting the unit, a check of the presence and quality of fuel is required. In this case, you should not be greedy and save, as well as “clever” about the amount of oil added. Everything must be done according to the management attached to the apparatus, since when the piston group fails, its replacement will cost about 70% of the total cost of the trimmer for the grass. Pour fuel due to the fact that you will fully conside it when performing work. After a while, the gasoline remaining in the tank loses its properties and can harm the engine. Therefore, do not prepare the mixture for the future and in large quantities. If the lawn mower starts poorly, try to drain the “old” fuel from the tank, and season it with a freshly prepared mixture.

Important! To refuel the device with fuel, the origin of which is unknown, fraught with negative consequences. Gasoline should be of high quality, bought at a gas station, and its brand should be not lower than AI-95.

Candle and candle channel

So, you changed the fuel, but nothing has changed, and the trimmer for the grass still does not start. In this case, it is worth checking the candle channel: whether it throws it with a combustible mixture. Often users transfer the air damper to the “OFF” position when starting, and when the engine started, they do not transfer it to the “ON” position, after which it stalls. Further, an attempt to start the internal combustion engine to again leads to the fact that it floods the candle with gasoline, and the start becomes impossible. To diagnose and eliminate the possible problem in this node, do the following.

• It is necessary to unscrew the spark plug, wipe it well and dry it. When installing a candle in the ICE cylinder, it should be dry.
• Draw from the combustion chamber the fuel accumulated there. This is done through the hole from which you twisted the candle.
• In the presence of soot on the electrodes of the candle, it must be removed either with a thin file or a nail file.
• Do not forget to put the gap between its electrodes before installing the parts in place. The gap on the candle should be 1 mm. As a probe to check the gap, you can use a coin.
• Next, collect the block, read the start instructions and try to start the engine again.

If the engine does not start, then you will need to check the spark. For this:

• unscrew the candle;
• put on it a cap of a high.voltage wire;
• Touch its metal part to the cylinder body (to provide contact, you can insert a tubular key) as shown in the figure below;
• pull the launch cord so that several engine speeds occur.

Normally, with each piston roll between the electrodes, the candle should slip a spark. If there is a spark, then the reason that the internal combustion engine is not launched should be sought in other nodes of the device.

For a better understanding of the process, how to test the candle for the presence of a spark, you can use this video where the check is shown by the example of the Lawn Mushiel “Soyuz”.

If there is no spark, then in the beginning check the cable connecting the candle to the coil. perhaps the reason is in it. You can call it with a tester. In case of detection of the rupture of the chain, a high.voltage wire will require a replacement.

Also the reason that the spark has disappeared is a malfunction of the ignition coil (magneto). The figure below shows what the coil (magneto) looks like from the gasoline trimmer for Patriot grass (Patriot).

To exclude the malfunction, it will be necessary to use a tester to check the Magneto trimmer for the grass, namely, its primary and secondary winding. On the primary winding, the resistance should be in the range from 0.4 to 2.0 Ohms. If the device shows 0. this means that there is a short circuit in the winding, and if infinity is a clear sign of a chain break. The resistance on the secondary winding should be in the range from 6 to 8 kOhm.

On some coils, it can reach the value of 15 kOhm.

Air filter

If your lawn mower does not start well or stalls immediately after starting, you should pay attention to the air filter, since it can be clogged, as a result of which the air does not enter the combustion chamber, and fuel ignition does not occur. To check if the filter is the case, remove it and try to start the engine. If he earned, then the reason was found. The filter needs to be replaced or rinse well and dry before installation. In the case when you find the oil in an air filter, it must be washed with gasoline, squeezed well and dry at least 2 hours before installing in place.

If the unit does not start with an air filter, it is still recommended to check the fuel filter.

Fuel filter

This filter cleans fuel of possible pollution. If it is scored, then gasoline does not enter the cylinder, and, accordingly, the unit does not work or stalls after starting. The fuel filter is located at the end of the fence hose, which is located inside the fuel tank. To get to the filter, it is necessary to extract a cork with tubes emerging from it.

When extracting traffic jams, a fence hose can disconnect and stay in a tank. It is extracted with a tweezer.

Next, remove the old fuel filter from the hose and put on it a new, pre.acquired. You can also clean the fuel filter if you do not have new. The filter must be fixed on the hose using a spring latch.

Install the fence tube on the cork and insert the last into the tank.

The reasons

Trammers for grass are reliable and durable (of course, subject to proper care). Most often, malfunctions arise due to contamination of structural elements.

If the engine of your lawn mower does not start, does not gain momentum, does not reach the power you need or suddenly stalls, it may be a reason:

• low.quality fuel (fuel mixture), it can be in long.term storage or in non.compliance with the recipe for the preparation of the mixture;
• The grass was wound on the shaft of the fishing/knife head;
• clogging of the air filter/muffler;
• Balance of the carburetor.

Ways to eliminate problems

The first three reasons are quite simple to eliminate. If the matter is the mixture, it is necessary to pour old fuel from the tank, prepare a new emulsion from high.quality gasoline and engine oil (if your motor requires a mixture) and pour it into a fuel tank. If a trimmer for grass works on clean gasoline, it’s still easier.

In the second case, it is necessary to carefully release the details of the trimmer for grass from the wound grass.

If the filter is clogged, you can try to rinse it. If this procedure has not brought the effect, replace it with a new.

The last reason why the lawn mower does not work properly will require you a little more knowledge and skills.

In order to properly adjust the carburetor of the lawn mower, it is necessary to observe a certain procedure. First of all, carefully clean the air filter. The easiest way to rinse it (it is advisable to carry out the filter with water regularly after 9-10 hours of operation).

After that, in the diagram of your trimmer for grass, which is in the instructions for the operation of the device, find the adjustment screws. Usually there are three of them: the first is responsible for the supply of fuel, the second. for idle, but the third is designed to limit the number of maximum engine speeds.

Next, you should turn on the unit and wait for the engine to warm up.

Slowly twist the first adjusting screw (fuel mixture). Catch the moment when the motor begins to stall, and turn the screw in the opposite direction 45 degrees. If you did not have time and the motor stalled, the screw should be turned 90 degrees. Open the throttle and see how the speed is going. Next, you should slowly unscrew the screw (each turn. the same 45 degrees) until the moment when, with full gas, the motor begins to firmly issue maximum revolutions.

The second screw, as mentioned above, controls the engine speed at idle. Weakening it, you reduce the number of revolutions, tighten. increase. The screw must be adjusted so as to ensure confident operation of the motor at small speeds. Accelerate the engine for better starting a little. At the same time, make sure that before the movement of the knives/coil with the fishing line, the motor makes several dozen revolutions. With poor starting the engine, screw the screw slightly.

After you have adjusted the first two screws, test the operation of the device at the maximum engine speed. If necessary, you can limit it (maximum). this will serve as protecting the motor from “boiling”. To do this, you need to do the third screw. Unscrew the fixation nut until the moment when the control screw can be calmly turned. To increase the maximum speed, the screw must be loosened to reduce. on the contrary, tighten. Fix the screw position with a nut. Test the work of the motor again.

Spend the position of the screws regularly. a high level of vibration characteristic of benzocoses can cause their involuntary shift.

Remember that carburetor adjustment is not the final procedure. During operation, Motokos, most likely, you will have to mess with it more than once, because an unbalanced carburetor is both an increased fuel consumption and a quick failure of the candles, not to mention reducing the power and productivity of the device.

Main reasons

The following reasons are possible why the lawn mower or trimmer for grass stalls when trying to re.start and continue the interrupted work:

• malfunctions in the engine;
• refusal to supply gasoline and oil;
• damage to pipelines (capillaries, hoses, pipes);
• malfunctions in the ignition system.

General description of problems with a scythe or trimmer is not enough here. Clear and immediate repair, high.quality maintenance is impossible without specifying the identified cause.

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.

With an increase in speed

If the lawn mower (or a trimmer for grass) has stalled when the engine speed is added, check the device according to the following signs:

• clogging or sticking a valve built into the gas tank cover;
• valve adjustment violation;
• A failure in the work of pistons and cylinders. from vibration during the work of a braid for grass or a trimmer for grass, random blows directly in the session of the mowing of grass;
• violation of the supply of fuel mixture;
• excess air pumping into the motor;
• cracking of the fuel intake hose, weakening its compounds.

When the fuel.heating mixture is served with the right portions to the engine in a timely manner. it burns the amount that has managed to enter from the moment of the last gallpling, and he stalls again.

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.

Immediately after the start

The stalling of motorcycles or a trimmer for the grass immediately after the start is due to the following reasons:

• impressive of previously adjusted valves;
• Initially incorrect setting of the valve mechanism;
• clogging with fuel supply valve;
• the hose is worn or poorly attached.

Due to the violated fuel injection algorithm, a lawn mower or a trimmer for grass is greatly vibrated in work.

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.

When opening an air damper

A lawn mower or a trimmer for grass stalls when raising the damper for the following reasons:

Ways to eliminate breakdowns

The following works are possible by carburetor:

• cleaning and adjustment of the fuel supply valve;
• similar work with a valve producing spent gases and pairs (after fuel burning);
• replacement of the spring weaker on the entrance valve;
• restoration of the tension of the carburetor cable;
• replacement of the fuel leaks hose, verification and strengthening of a weakened connection;
• changing the rotor damper disk;.
• Change of faulty wire or ignition coil.

The list of work on the work may also include the cleaning of the nozzles (in a 4-stroke engine), replacement of the valve washer, gaskets in tanks and so on.

The lawn mower starts and stalls

The constant operation of lawn mowers leads to wear of some parts, as well as breakdowns. This usually happens at the most inopportune moment. How to repair a lawn mower with your own hands? In what cases the situation can be corrected independently, and when the help of a specialist is required?

When the lawn mower does not start

Depending on the area of ​​the lawn and the growth of grass on it, the owners choose the optimal technique in characteristics. It is several types:

Also, the restoration of lawn mowers with your own hands will be required if the conditions of winter storage are inappropriate. For example, after use, there were no cleaning surfaces or there was no off.season preventive maintenance. As a result, various problems are manifested:

• frequent sharpening of the lamp of the lawn mower is required;
• just does not start a lawn mower;
• The motor starts up, but through a short gap the lawn mower stalls;
• malfunctions of the carburetor appear, which requires not only disassembly, but also cleaning with repair;
• Do.it.yourself renovation of the lawn mower is required with a significant reduction in power during operation.

You should not go to an expensive service center. Many problems can be solved with minimal costs and repairs on your own.

After each use of the tool, it is necessary to clean the cutting elements. Change the oil regularly and perform a minimum risk.

Problems with the mechanical part

The mechanical system in lawn mowers with different drives consists of the following structural elements and nodes:

• knife (rotary or cylindrical type) or fishing line;
• transmission mechanism;
• grass collector and grass emission devices;
• wheels, handles and housings.

The failure of the cutting element

The most commonly damaged (for example, bend) or knives are blunt, the fishing line for the trimmer ends. This is easily detected with a simple visual inspection.

The fact that the cutting nozzles have become swept away is evidenced by uneven cutting of herbal stems when the lawn mowed.

Over time, knife fastening can weaken. Their balancing during rotation is disturbed, and vibration, whistle, rattling appear. If the knives are damaged, then during operation the mechanism will begin to perform unguided, sudden, sudden movements. To eliminate the malfunctions of this kind, the cutting elements are set to the right position, replaced with new ones or repaired. If possible, then the blades are pulled again.

Sounds and vibration during work

Uncharacteristic sounds, vibration, rattling appear during the operation of the unit, when the fasteners of its structural elements are weakened: body, engine. These phenomena are more often found in gasoline models, because their motor fluctuates more strongly than the electric motor. To eliminate these phenomena, check all the connections, pulling up the bolts if necessary. It happens that the whistle during the operation of the unit arises due to the entry into an outsider that blocks the video in the aerator. In this case, it is enough just to get it so that the sound stops.

Cutting nozzles do not rotate

Often, when mowing a high herbal cover or hard herbal, cutting nozzles cease to rotate due to grass clogging. This problem in most cases (if it has not led to more significant negative consequences) is easy to solve with your own hands, just picking out a stick with a stick.

Damage to constructive details

Damage to the wheels, handles and housing rarely happen. If they are significant, then they change these structural elements. Methods of repair, with its possibility, in each case, depend on the material of broken parts. they can be plastic, aluminum, steel.

Brand break

With prolonged operation, the mower wear out, stretches, and then the belt breaks off. At the same time, the device’s gasoline engine works, but the knives do not rotate. Self.propelled models can also break off the wheel drive belt: then they stop and do not go. Sometimes the clutch cable simply stretches and it needs to be adjusted.

The most common breakdowns

Any technique sooner or later fails. It is important to know how to repair mowers, because not in all cases you need to contact the service center.

The braid does not cut the grass

In most cases, the cause is dumb or severely damaged knives. To achieve the best results, just change the knife every year. Choose a knife suitable for your model. When the knife is swept away, you can sharpen using electrofig or file. When sharpening, be sure to use goggles and gloves. Angle of sharpening on both sides. about 30 degrees.

Simple sharpening devices can be purchased in stores. Before installing them, it is necessary to turn off the mower from the network and adjust the cylinder positions in such a way as to highlight the maximum cutting gap.

In cylindrical braids, the gap between the knife and the cylinder should be less than the thickness of the sheet of paper. Some of the most modern models have built.in regulators with notches. In other cases, you will have to use keys and screwdrivers to carry out the necessary adjustments. Follow the uniformity of the gap along the entire length of the cylinder. To check the adjustment, insert a sheet of paper between the cylinder and a knife, slowly rotating with your hand. Gradually adjust on both sides until the paper begins to cut purely at each point of a motionless knife.

It is difficult to move the mower

• When the mower hardly moves along the lawn, you may try to remove too high grass and you will have to adjust the level of mowing. When seizing rollers or wheels, they need to be inspected to make sure that there are no scraps of grass and garbage. Most likely, they need to be removed and cleaned.
• If an interference for air is formed, then the lifting force will decrease on the mowing air pillow, and it will become difficult to move it. Air lack leads to overheating of the engine. Disconnect the power and remove the remaining grass from the air intake grilles.

Frequent breakdowns of the lawn mower: review and solution to problems

Using a gasoline lawn mowing for cutting the lawn, you need to be careful and follow the operating rules exactly. After completing the work, the device must be cleaned, since even a small clogging can block a moving mechanism. If frequent breakdowns of the lawn mower occur: the review and solution of the problems can be found by reading this article.

The reasons

The main reason for the malfunction in the work of the mechanism can be called the application for other purposes. Possessing knowledge about the principle of work and mechanisms of garden equipment, it is possible to eliminate problems with your own hands. But it is still better to contact a specialist, especially with serious breakdowns. Among the breakdowns that are most often found, the following can be distinguished:

The reasons for the weak.speed trimmer for grass

If users complain to the trimmer for grass, which does not gain momentum, this means that it works normally on idle, and when pressing gas does not develop the necessary power. This can happen as a result of a long downtime of the apparatus without activity. These problems are typical for gasoline devices, including the Husqvarna 128R, STIHL FS 38 and Hitachi different modifications.

Working with a trimmer, you need to monitor its behavior all the time. a drop in revolutions and unusual noises signal the malfunctions in the aggregate. Sometimes you give gas, and the trimmer for the grass swims. In such cases, the work should immediately be suspended, let the mechanism cool and start searching for possible problems. They can be of a different nature of both the technological plan and external factors related to the conditions and features of the operation of the device.

External factors

Several factors that are not related to its breakdown affect the reduction of revolutions:

• filter pollution due to the hit of particles of dirt and dust in it;
• use of poor.quality fuel;
• incorrectly prepared mixture (relevant for trimmers with two.stroke gasoline engines);
• pollution of the muffle of muffler particles of vegetation, soil elements and other objects.

In this case, in the second and third cases, the formation of a soil in the combustion chamber is formed, and the elements of the carburetor are clogged.

technical issues

The technical problems of the lawn mower mainly occur in the fuel and ignition system. You can cope with them yourself.

• Когда ручная косилка не заводится или глохнет, проблема может быть связана со свечой. The dark cargo speaks of poor carburetor adjustment and low gasoline quality.
• The reason for the incorrect operation of the trimmer for the grass may be clogged fuel hose. Filters are also often clogged.
• Another internal problem. the muffler is covered with soot. From this, the turnover of the grass for the grass falls strongly. Output. you need to clean the muffler.

What to do if a trimmer for grass stalls when you press the gas?

So why is a trimmer stall for grass when pressing for gas ? There may be several reasons for this problem.

• The carburetor was resolved after an unsuccessful wintering or after too intense use of motorcycles. The gasoline trimmer for the grass operates on the air-fuel mixture that the carburetor prepares it. With improper adjustment, this mechanism prepares a depleted mixture that is not capable of providing the engine with quite high speeds. You can understand about the problem with the carburetor by the characteristic vibrations of the lawn mower.
• You will learn about the clogging of the fuel filter by the fact that the trimmer for the grass starts and stalls. In other words, the flow of fuel is enough to start a motorcycle, but is no longer enough to maintain the engine in work. It may be possible to solve the problem with weakening valves on the filter. If not, you should rinse the filter in solvents and blow it with compressed air. If after and this is not solved the problem, then you should purchase a new fuel filter.
• If the engine stalls at speeds close to maximum, then perhaps the problem with the saope that regulates air access to the gas tank. If the fuel consumption is too fast, characteristic when you give gas, rarefied pressure is formed in the gas tank, due to which the fuel flow into the engine is reduced.
• The engine stalls when opening the damper. The problem, again, is associated with a carburetor, which, due to an excess of air, prepares a depleted air-fuel mixture, which is not capable of ensuring engine operation.

The lawn mower stalls at high engine speeds

During operation, a situation arises when, when pressing the fuel supply key, the aggregate turnover begin not to increase, but to decrease. A malfunction of this nature can be caused:

• 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.

How to get a lawn mower when the engine stalled at home

It is especially difficult to start a lawn mower after a long downtime. What to do to the user when a gardener refuses to work:

• If the device has not been cleaned for a long time, you need to rinse the air engine, it is cleaned with gasoline (it is advisable to do this every 24 hours of work). You can remove the filter from the device and start the unit, if the mower is working, then the reason lies in this.
• After winter, the remnants of old gasoline in the tank can interfere with the work of the device. The problem is easily eliminated if you replace the fuel with a new.
• Insufficient amount of oil in the crankcase. can also be the reason why the gasoline lawn mower is not started. Check its presence, is there a fuel in the tank.
• Incorrect location of the air damper during the first launch. At a temperature of ≥ 30 s. it should be in the middle position or closed. With repeated launch. open.
• Jamming the knee shaft, piston. you can eliminate if these details are slightly moving. The main thing is to do it carefully so as not to break the mechanism.
• Boarding of the Sapun. the supply of fuel stops, you need to clean the part.
• Dry threaded connection. while the factor does not have a spark of ignition, the connection of the gasoline should be lubricated.
• Failure of spark plug. accumulations on it oil, plaque. The candle is twisted, well dried, cleaned with a file. Excess fuel merges, dries at least 30 minutes. candle hole. Perhaps the part will have to be replaced if it fails to clean it.
• The contact of the high.voltage wire and a candle for the presence of a spark is also checked. If the latter does not arise, the ignition system is not allowed to determine and eliminate only in the service center.

The lawn mower is not started after winter

In such cases, it is necessary to conduct maintenance of the unit. Remove the fuel system, including filters (air, fuel), disassemble the carburetor, clean each node, rinse. Pour the filters with air. Pay attention to the quality and octane fuel number.

It must be taken into account that the products of such well.known companies as Stihl, Husgvarna and other brands will not work on a cheap octane number of gasoline. For them, suitable fuel from the AI ​​brand. 92 and higher with car gas stations and that, with well.proven ones, since gas stations are also bad gasoline. On the use of highly octane and high.quality gasoline, it will depend on how long the lawn mower will be used and how much it will last.

One more fact must be taken into account that with the long storage of diluted fuel mixture, it falls working qualities, which also leads to the consequences in which the lawn mower will not start. Therefore, it should be diluted with portions, that is, the amount of a mixture that is produced at a time. The operating instructions clearly describe and are given clarifications on the proportion of mixing gasoline and oil. Straighten compliance with the correct proportions will at least save you from several questions, why the lawn mower will not start and what to do in such cases.

The lawn mower starts and stalls. What to do?

There is a spark, and everything seems to be normal, but the lawn mower is not started, in such cases, you should check the air access valve into the fuel tank. Clogging of the valve leads to the creation of a vacuum in a tank, in which the carburetor does not receive gasoline, so the lawn mower will start, but then it will die out. To exclude this reason, you need to clean the valve and try to get a lawn mower with a not fully twisted tank traffic jam. 2. If at the same time the lawn mower is not started, you should remove and clean the fuel filter, as well as check all the parts of the carburetor, and then try to start. The lawn mower is not started again, the air filter is disconnected, try to get without it if the gas station has started to mean the reason in the air filter, replace it.

The loss of the spark entails a check of contacts and the correctness of the clearance between them, conducting the wire to the candle and the candle itself. A method of checking the spark. to unscrew the candle, connect the wire to it, attach the candle sideways to the casing of the engine and pull the lawn.mower as if starting the starter several times, while you need to look at the corner and contact of the candle, the spark should run between them. If there is no sparks, take a new candle to do the same procedure, if the spark is not traced, the problem in the wire or contacts means it, it is better to replace them.

Why is the lawn mower stall at idle

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

Users have repeatedly ask about stopping the braids for the grass “on hot”, that is, when the mechanism started, worked a little, and then took it. and stopped, stalled. The reasons for this situation are the following:

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

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

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

We are sure that you received the maximum of useful information, and found a way out of your individual situation through our technical councils. Any spare parts, like a starter, motorcycles, its components and accessories are located at the lowest value in the country. Hurry up!

Recently, a gasoline trimmer for grass has acquired the status of one of the main tools in the arsenal of summer residents. And this is not surprising, because a motorized braid for grass allows you to quickly put a personal plot in order. However, sometimes it happens that the trimmer for the grass does not start hot and even on cold.

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

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

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

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

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

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

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

If a carburetor is a problem place, then the technique will stop at the “cold” and with a “hot” launch.

Main reasons

The following reasons are possible why the lawn mower or trimmer for grass stalls when trying to re.start and continue the interrupted work:

• malfunctions in the engine;
• refusal to supply gasoline and oil;
• damage to pipelines (capillaries, hoses, pipes);
• malfunctions in the ignition system.

General description of problems with a scythe or trimmer is not enough here. Clear and immediate repair, high.quality maintenance is impossible without specifying the identified cause.

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.

With an increase in speed

If the lawn mower (or a trimmer for grass) has stalled when the engine speed is added, check the device according to the following signs:

• clogging or sticking a valve built into the gas tank cover;
• valve adjustment violation;
• A failure in the work of pistons and cylinders. from vibration during the work of a braid for grass or a trimmer for grass, random blows directly in the session of the mowing of grass;
• violation of the supply of fuel mixture;
• excess air pumping into the motor;
• cracking of the fuel intake hose, weakening its compounds.

When the fuel.heating mixture is served with the right portions to the engine in a timely manner. it burns the amount that has managed to enter from the moment of the last gallpling, and he stalls again.

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.

Immediately after the start

The stalling of motorcycles or a trimmer for the grass immediately after the start is due to the following reasons:

• impressive of previously adjusted valves;
• Initially incorrect setting of the valve mechanism;
• clogging with fuel supply valve;
• the hose is worn or poorly attached.

Due to the violated fuel injection algorithm, a lawn mower or a trimmer for grass is greatly vibrated in work.

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.

When opening an air damper

A lawn mower or a trimmer for grass stalls when raising the damper for the following reasons:

• swinging excess air due to the cracked fuel suction hose;
• sealing oil seals;
• improper functioning of the fuel and air dispenser when mixing them.

Stop motokos in this case is immediately.

When heated

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

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

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 of fuel hose cracks or problems with the oil 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.
