When you press the gas engine, the motorcosa stalls. Ways to eliminate breakdowns

The reasons for the fall in the motorcycle. The lawn mower does not develop full power

Any person owning a country or land plot is well aware of the problems of the fight against excess vegetation. Now a trimmer for the grass has come to the rescue, which successfully replaced the usual braid in this field. This unit is very convenient in work, but it, like any mechanism, also, due to difficult working conditions or incorrect operation, is characterized by failing. Situations are quite common when a trimmer for grass does not gain momentum. To understand this problem, it is necessary to understand some aspects related to the functioning of the device.

All trimmers for grass are classified according to the type of power: gasoline or electricity (from the network or battery). It should be noted that gasoline mowers in many respects exceed their electric and battery analogues. Despite the fact that they all perform similar functions, the difference in performance, maneuverability and effectiveness is very noticeable. However, the general principle of operation of all types of manual braids is almost no different- the devices are equipped with engines (two- or four-stroke ICE or electric motors), which drive the cutting unit (reel with fishing line or metal disk). All elements are fixed on the line of straight or curved shape, including the handle for controlling the trimmer on which the main buttons are located.

Since the problem of weak revolutions is more characteristic of gasoline trimmers, they will be given more attention. So, the lawn mower is very comfortable in work and unpretentious in maintenance. over, most of its malfunctions are caused by ignorance by the user of elementary things, which are written in the instructions. Therefore, before starting the operation of the unit, it is necessary to carefully study the management of the manufacturer. In particular, in order to start the engine, it is necessary to do the following sequential actions:

  • turn on the ignition button;
  • press the silicone button for pumping gasoline several times;
  • close the air damper;
  • The gas lever is installed in a position for high speeds;
  • first make non.leaf with the starter handle to feel the engine resistance, then jerk sharply.

If the lawn mower started up, but stalled, you need to put the air damper in the middle position and repeat the attempt. When the engine works, you need to slow the gas and open the air damper, since the trimmer for the grass functions only on the leak.

Important! The mode of operation of the trimmer for the grass depends on the various environmental influences. In hot weather, the unit should be given more time to cool. When working in conditions of dense thickets or high vegetation, the engine also overheats strongly. It is necessary to take five-minute breaks every 15-20 minutes.

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.

Important! If the unit does not work due to breaking up the engine, serious problems may occur. In this case, the malfunctions that can be eliminated with your own hands include only the destruction of piston rings. With more serious problems with the motor, if there is no warranty, you should be prepared to visit the workshop.

Carburetor adjustment and configuration

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

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

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

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

Well, even if after such bullying your trimmer does not start for the grass, you can’t do without disassembling the carburetor. It may very well be that everything is to blame for the gathering of the needle in it. It stalls in idle. Когда нагреется ее триммер для травы сразу глохнет почему глохнет. Why is hot stalling ? Actually, if you take a hot one for a hot trimmer for grass? Hitachi. In any case, the disassembly and washing of this capricious mechanism certainly will not hurt.

In general, when a trimmer for the grass began to be capricious and stall, it is advisable to carry out complete prevention: to completely change the fuel mixture, try another oil, and also mandatory change the candle. Practice shows that in many cases, it is precisely cheap low.quality candles that are to blame.

We examined the most typical reasons why a trimmer is not started for grass. If the matter is something more “exotic”, do not pass the campaign in the service center. You will probably find smaller and obvious breakdowns yourself.

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.

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.

The gasoline trimmer for the grass starts and stalls

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

Recently, a gasoline trimmer for grass has acquired the status of one of the main tools in the arsenal of summer residents. And this is not surprising, because a motorized braid for grass allows you to quickly put a personal plot in order. However, sometimes it happens that the trimmer for the grass does not start hot and even on cold. In such situations, you have to independently establish the cause of the malfunction. Let’s find out what to do if a trimmer does not start for grass. The reasons that most often lead to such troubles will be considered further.

Diagnostics strategy

Where to start the diagnosis of malfunctions if a trimmer is not started for grass? In situations where the tool stalls immediately after starting, it is worth examining the following units:

It is the breakdown of the above locations that most often leads to the fact that a trimmer for grass is poorly started. Let’s look at how to eliminate such troubles.

Checking the fuel mixture

Suppose you don’t start a trimmer for grass. In this case, the first thing is to check whether the fuel is enough in the tank, as well as evaluate the quality of the fuel mixture. To refuel a motorized unit, it is necessary exclusively high.quality gasoline. It is recommended to use fuel, the brand of which is not lower than AI-95. Refueling a trimmer for grass with fuel of unknown origin, not bought at a gas station, is fraught with frequent failures in the work of the tool. This can cause a breakdown of the cylinder-piston system. Repair in this case often exceeds the cost of the device itself.

Why is a trimmer not starting for grass gasoline? Incorrect preparation of the fuel mixture may also lead to this, which consists of oil and gasoline. The proportions in which the specified components are connected are indicated by manufacturers in the guide for the operation of a trimmer for grass. Preparing the fuel mixture is extremely not recommended in large volumes, that is, for the future. Indeed, with prolonged savings, there is a loss of the determining properties of the substance. Therefore, if a trimmer for grass does not start, it is worth draining the old fuel and use freshly prepared fuel mixture.

Read which trimmer for grass is better than rotary or vibration

Diagnosis of the candle channel

What to do if the used fuel mixture is in perfect order, but a trimmer for grass is still not started by gasoline? The reasons for the refusal of the mechanism may lie in excessive moisture of the candle channel. To diagnose and eliminate the problem, it is necessary to do the following:

  • To twist the candle. Wipe it thoroughly, and then dry it.
  • Drain excess fuel in the chamber through the corresponding candle hole.
  • Clear the old candle if there is a dozen on its surface. Cope with the task will allow the use of a conventional ladies’ nail file or file.
  • When installing the element in place, set a gap of 1 mm. To check the parameter, it is enough to place any coin in the lumen.
  • Collect a functional block back.
  • Try to start a trimmer for grass.

It is recommended to perform a candle channel to dry for at least half an hour. However, in no case should you resort to the calcination of its elements. After all, heating the spark plug can lead to its final corruption. Что предпринять, если обслуживание функционального блока было выполнено в соответствии вышеуказанным рекомендациям, но триммер для травы не заводится, искра есть при этом? In this case, it should be treated with gasoline threaded connection. The latter does not need to be saturated abundantly fuel. It should only be slightly moisturized. Resort to such actions should be to ensure the ignition. After all, no matter how much the candle gives a strong spark, in an absolutely dry chamber there simply will not be something to ignite.

Even more information about the repair and choice of tools on our website www.Looktool.Ru, we are happy for everyone.

If even in this case a trimmer for grass does not start, it is worth evaluating the quality of the contact between the high.voltage wire and the candle. In the absence of a spark (in the presence of a reliable connection between the indicated elements), most likely, the problem is caused by breakdown of the ignition unit. In this situation, you will have to turn to the services of masters who will reinstall the knot.

Checking filters

Another common cause, due to which a trimmer for grass does not start, is the presence of a blockage in the filter area. To confirm the conjecture, just dismantle the indicated block and try to start the unit without it. If the engine of the trimmer for the grass has launched, most likely you will have to replace the air filter or at least perform a thorough purge of the old. In the presence of abundant contaminants on the surface of the filter element, it is necessary to use a new grid. Relying to such actions, you should not leave a suction pipe at all without a filter. After all, rush in this case can lead to the need to repair the entire piston group of the unit engine.

Cleaning the soundtress

Often the engine of branded models of trimmers stalls as a result of clogging of the soundtress. The main task of the specified component is to align the pressure in the fuel tank. In the case of contamination of the node, a vacuum is formed here, which significantly complicates the supply of fuel. Eliminating the malfunction allows the cleaning of the saapon using a conventional sewing needle.

Diagnosis of the graduation channel

The stable functioning of a trimmer for grass can be impaired as a result of laying dirt in the graduation canal or the formation of a blockage on a muffler grid. This problem most often occurs during the operation of older generation trimmers. The issue is being solved by dismantling the anti.diploma mesh and its cleaning.

How to prevent sudden breakdowns during the operation of a trimmer for grass?

So that the unit is always in a functional state, it is worth observing several simple rules:

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.

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.

The lawn mower does not develop speed.Another reason

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

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

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

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

In this case, the problem may be as follows:

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

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

The gasoline trimmer for grass stalls at idle

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

Gasoline trimmer for grass stalls at idle

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

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

Problems in electronics

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

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

Carburetor adjustment and configuration

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

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

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

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

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

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 idle

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;

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

A hot engine stalls on the go or on idle

To begin with, the symptoms and signs of the indicated malfunction can manifest themselves in different ways. Quite often, the power unit can stall in idle mode, and unstable operation and a complete stop of the ICE often occurs after heating the motor.

First of all, diagnostics should begin with checking the spark plugs and their condition. In parallel, the high.voltage armored pipelines should be checked. This must be done due to the fact that weak sparking or complete absence of a spark on candle electrodes is possible. Interruptions with a spark lead to serious malfunctions in the operation of the motor, as a result of which both a cold unit and after warming up the engine stalls. Solving the problem is often helped by replacing spark plugs and high.voltage wires.

Another common situation is when the engine stalls on hot or cold immediately after its launch. In this case, on many modern cars with an injector power system, checked the idle sensor. The output of this element of the electronic engine control system often leads to the fact that the motor in idle speed is simply incapable of working.

Rocket engine cycles: How do you power a rocket engine?

In some cases, cleaning the XX regulator helps, in others the device should be replaced. On machines with carburetor, clogging of idle jacket and other malfunctions of the carburetor can be clogged. Injector engines also require additional verification of the synchronization sensor (wood-polymer composit), possible problems with the gasoline pump should not be excluded. One way or another, if the engine stalls on a hot or it constantly happens with a cold unit, then an in.depth diagnosis will be required.

If we talk about why the machine stalls in idle when the engine warms up, then the reasons can be similar to those cases when a warmed unit stops directly in the movement. This happens as a result of heating certain elements of the engine, after which the temperature expansion occurs and the failure occurs.

On carburetor cars with a mechanical ignition distributor, a situation arises when the runner ceases to perform its functions. Often often after warming up the ICE, the central wire on the ignition coil may leave, there are problems of the ignition unit capacitor, etc.D. A well.known problem of cars with a mechanical gas pump is that the engine stalls in the heat. This is due to overheating, since the high temperature overboard and a significant heating of the engine compartment do not allow the pump to cool normally.

At the same time, attention should be paid to the state of fuel filters. If the filter element turns out to be clogged, then during the growth of the load and set of revolutions to the engine through the contaminated filter does not receive the desired amount of fuel and the motor stalls

press, engine, motorcosa, stalls

We add that usually before a significant decrease in the capacity of the filter and a complete stop of the motor, the malfunction progresses. At first, the car may not gain speed, it starts poorly, failures appear when you press the gas pedal, the engine is unstable or twitches when you press the accelerator, in transition modes, etc.D.

Modern cars with an injector have an electronic control unit (ECU, ECU), the indicated unit is rare enough, but still fails. In this case, the motor may stall on the go, and the problem itself is manifested in different situations, including after warming up the ICE. In this case, as well as if it is necessary to check the individual squad sensors, it is necessary to conduct computer diagnostics of the car. The system will display existing errors in the form of codes, after the decryption of which it is possible to localize the malfunction. If the problem is “floating”, that is, it occurs periodically, then it is recommended to purchase a compact device that allows you to read information about the engine operation through the OBD connector. Thanks to the subsequent output of the data on the screen of a smartphone, tablet or laptop with a pre.installed program, the specified solution will make it possible to fix failures in real time.

When opening an air damper

It happens that the aggregate stalls at Air opening

shutters, 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.

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.

Карбюратор регулируют , опираясь на эксплуатационную инструкцию к триммеру. Для настройки часто бывает достаточно ослабить затяжку его корпуса. Если существуют проблемные моменты с циркуляцией топливной смеси, то она может понемногу поступать в карбюратор. После ее выработки двигатель глохнет при больших оборотах.

Диагностика неполадок

Все причины, почему не заводится газонокосилка, можно классифицировать по специфике работы отдельных узлов. В сервисном центре неисправности классифицируют:

  • неисправность двигателя (износ поршня, неисправность подшипника, трещина картера);
  • неисправность подачи топливной смеси – забитые поры воздушного фильтра или неисправность карбюратора;
  • не работает система зажигания;
  • неисправность механического характера – протечка шлангов, сломанные провода под оплёткой, разрыв трубок.

Пользователю в первую очередь нужно проверить, есть ли в баке горючее. Запуск проводить в соответствии с инструкцией, положив пилу на бок. Воздушную заслонку установить в положение «закрыто», подкачать топливо, включить зажигание и произвести 3-4 резких рывка стартёром. Если двигатель заработал, открыть заслонку воздуха. Не заводится газонокосилка – повторяем операции при слегка открытой воздушной заслонке.

газонокосилка не может работать долго. Перегреется редуктор и двигатель. Косит можно не более 15=20 минут, делая пятиминутный перерыв. В знойный полдень время работы сокращается вдвое. При скашивании бурьяна, осоки время работы требуется сократить.

При неудачном запуске, начинаем искать причину отказа:

  • проверить качество топлива;
  • убедиться в работоспособности свечи и чистоте свечного канала;
  • проверить чистоту воздушного фильтра;
  • убедиться, что топливный фильтр не забит;
  • проверить чистоту сапуна;
  • прочистить выпускной канал.

Более сложными причинами станут, обнаруженные при диагностике неисправности, приводящие к капитальному ремонту карбюратора. К таким причинам относят засорение внутренних каналов карбюратора, износ на нём прокладки и нарушение герметичности внутренних холлов с потерей вакуума. Ремонт газонокосилки своими руками, если она не заводится, потребует терпения.
