Benzotrimmer poorly develops the moment. Features and best models

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.

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.

Reasons why the lawn mower does not develop momentum

There are five main reasons why the trimmer for STIHL grass does not develop turns:

Low quality fuel use

Benzotrimmer does not gain momentum in case of low quality fuel. He may stall or not start at all. To check the quality of the fuel, you need to inspect the candles. They are. The main indicators for problems with the combustion chamber.

In the presence of sediment, plaque formed on the candles, the old fuel is drained and flooded another, high.quality.

It must be remembered that a trimmer for grass or a lawn mower should be refueling good quality gasoline and those fuel brands that the manufacturer indicated in the technical passport of the device.

Note! Candles should be thoroughly cleaned of plaque, and only after that place again in the combustion chamber of fuel.

Air or fuel filter pollution

There is a lawn mower does not gain speed, the reasons may be polluted by the filter element: air or fuel.

When blocking the air filter, there is a lack of oxygen in the combustion chamber, so the fuel is not fully produced, which prevents the desired speed and power.

To check if the cause is really in the air filter, you need to remove it and turn it on. If the lawn mower still does not gain momentum, the reasons are not in it. So you should check the fuel filter element. Everything is similar here, only gasoline acts as oxygen. If this filter is damaged, there will be a lack of fuel, which inhibits the development of revolutions.

In one and another case, the output is simple: you just need to replace the filter. If there is a spare, to install it, if not, to purchase in any specialized store, is inexpensive.

Problems with ignition candles

When a benzotrimer is used often, you need to monitor the state. This part is susceptible to wear, so they need to be regularly examined: is there a Nagar on them.

You can solve the problem in two ways: clean the old candle from Gary or purchase a new one.

In the first case, you need to unscrew and swing with sandpaper, dry. The distance between the electrodes should be 1 mm. Trimmer for grass is collected and advanced.

In the absence of a spark between the electrodes, it is worth inspecting the quality of the connections of all the elements of the circuit. If in this case everything is fine, then 100% you need to change the candles.

Replacing them is easy and inexpensive. From the tools will be needed a key, supervisor.

Important! With frequent appearance of soot on the candlelights, it is worth looking for a reason a little deeper.

Candles should be carefully cleaned of plaque

Problems with the engine

Engine problems. Already more serious. There are several options for a malfunction:

In the case of the problem of the carburetor, you should first pay attention to the condition of the cable. It can be weakened, which led to a problem. A simple adjustment of the cable is required here.

If this did not help, then you need to check the use parameters. These operating standards can be found in the technical passport of the device. Sometimes it’s enough to disassemble the device: to wash and collect and assemble.

note! The solution to the problem with the carburetor may be the purchase of a new element or by contacting the service for professional services.

The trimmer drive is subjected to a full check only if the manipulations with the carburetor were not given the proper result.


The lack of fuel circulation in the system can also be the reason why the device does not gain momentum. There are several options for why this is happening:

You can eliminate problems yourself. For this you need:

  • remove blockages from the gasoline pump;
  • update hoses, pipes for fuel circulation;
  • Clean the muffler and mesh on it;
  • Reinching a new catalyst.

Do not worry when such problems arise. This does not mean at all that the unit of poor quality. If the Patriot trimmer does not gain momentum, it can be repaired with your own hands without contacting the service.

For what reason does an electric braid for STIHL grass do not develop full power

When using an electric trimmer for the grass, non.aviation problems may also occur. Here the reasons are completely different than that of fuel cos.

You can eliminate problems yourself

Eletric trimmer for grass does not develop the required power, because:

  • The voltage in the network is below the required minimum for the device more than 10%;
  • There was a failure on a smooth launch (if there is such a system);
  • there was a malfunction of the brush node;
  • The engine winding was burned;
  • rotating parts sometimes jamming.

To establish voltage, you should first check its power. If it does not meet the norms, it should be increased using a stabilizer.

The repair of the smooth start system is carried out only in the service center.

note! With wear of brushes, you just need to replace them. When installing new ones, it is recommended to clean all the surfaces with which they contact.

To establish voltage, you should first check the power.

When burning engine windings, you need to change the electric motor.

Jamming of parts of rotation can occur for various reasons. To eliminate them, you should review the entire drive unit.

Note! The last problem may also arise in another unit of this company. STIHL secateur, and the sharpening of the disk on the scissors will be its solution.

Maintenance of a trimmer for grass using the example of Husqvarna 333r to prevent the repair of a trimmer for grass

T.O. We make trimmers for grass (lawn mowers) so that:

  • In the heat and at any load, the trimmer engine for the grass did not overheat;
  • ensure accurate adjustment of the carburetor and, accordingly, optimal operation of the motor motorcycles;
  • identify possible defects, seeping fuel and other malfunctions to avoid repairing a trimmer for grass;
  • Timely change the spark plug, unreliable bolts, gaskets and other consumables;
  • so that a trimmer for grass (lawn mower) has a good appearance;
  • so as not to carry a trimmer for grass to the service center.

T.O. We carry out trimmers for Husqvarna grass after rolling out every 40. 60 liters. gasoline

(depending on the heat, dusting and severity of work).

Serving the air filter of a trimmer for grass

I wash the air filter after a engine rolling out every 20 liter of gasoline and before making the repair of a trimmer for grass or maintenance of a trimmer for grass.

To serve the air filter, you need to: remove the foam element of the air filter and wash it with soap in clean and warm water, squeeze and dry (or replace if the foam filter element is old or damaged).

Note: Air filter can be “washed” and more often in order to prevent power drop, increased fuel consumption, launch difficulties, as well as the vain wear of the engine of the lawn mower.

Note: If you adjust the carburetor of a trimmer for grass with a dirty air filter, then after cleaning the air filter, the air, the engine will enter the more and the fuel mixture will become much poorer, which will lead to poor operation or even to break the engine and, as a result, repair of the trimmer for grass.

Preparation for the maintenance and repair of a trimmer for grass

  • Provide (buy and dilute) the fuel mixture usual for the work of your trimmer (for example-A-95 “Mustang” gasoline with a WOG gas station and the Husqvarna two-stroke oil, in a ratio of 1:50) and leave 1.5 liters of clean (without oil) gasoline for washing engine parts;
  • Buy a new spark plug: only Champion RCJ6Y. according to the instructions of the manufacturer Husqvarna;
  • Prepare water-wide accessories for t.O. and repair of a trimmer for grass (~ 7);
  • Prepare benzo-musical accessories (~ 5);
  • buy the necessary Bolts and screws of Husqvarna for repairing motorcycles (new fasteners);
  • prepare a thin paronyte for a gasket for a carburetor of a trimmer for grass, a fishing line for a “round” trimmer 2.7-3 mm, gear lubrication, clamps, fuel filter;
  • ensure good lighting, cleanliness of the room and a workplace for the repair of a trimmer for grass (a baking sheet for laying out parts and spare parts, a stand for the motor, lining for keys and tools);
  • ensure personal performance (if necessary);
  • To allocate one free day specially for maintenance and repair of a trimmer for grass (lawn mowers).

The start of maintenance and repair of a trimmer for grass

  • Add grease to the gearbox of a trimmer for grass. Remove a metal knife or trimmer head and clean the leash cartridge inside of lubrication and earth.
  • Wash with warm water and brush everything on the steering wheel, everything is on the bar and both protection (the protection of the lawn mowers, as a rule, overgrown with a dried mixture of the ground and juice of grass, so it is advisable to clean the plastic protection with a brush for metal, and then with washing powder and brush. Rinse and dry everything.
  • Inspect everything on the trimmer for the presence of cracks, bent, scuffs, distortions, tears (especially metal knives at the base of the teeth and at the holes and both protection). Reliably eliminate all the malfunctions identified on the motorcycle. Remember!. The thickness of the metal is calculated on the computer, because the tightening of the fasteners should be carried out only in the service center on a special mash tightening of fasteners with a dynamometric key. If the fastener is tightened by yourself, then do not pull!, since with strong warming up (for example.- gearbox) in the heat with a large load, the metal expands, and the stock is not enough and the body can burst (give a crack).
  • Install a trimmer head (T-35) with a cord of 2.7 mm or 3 mm of standard length (to a cutting knife in additional protection) to load the engine to adjust the needle of high speeds, that is, the trimmer carburetor’s left screw for grass.
  • Remove and drain the fuel from the tank into the bottle.

Dismantling a trimmer for Husqvarna 333R grass (engine disassembly for T T.about. and repair of a trimmer for grass

Remove the muffler cover. one bolt.

Turn the trimmer for the grass on the table and remove the metal pallet (three screws).

Remove the block starter (this is the air intake of the engine cooling system for grass)-three screws and two elastic bands!

Unfasten the air filter cover and remove the cylinder cover (it directs cold air to the cylinder). one bolt.

Wrap three bolts in the air filter housing (one short and two long).

Carefully disconnect the gas cable from the carburetor.

Inspect everything dirty so far. a carburetor on a trimmer and its gaskets, hoses, a tank, a cork for leaking fuel (cracking and leaks).

Remove the fuel tank with two hoses (disconnected by the screwdriver very carefully) and four supported elastic bands (do not lose).

Remove the Zama C1Q carburetor along with the air filter housing and gasket.

Remove the leaks button with a screwdriver (there you need to make a label for the subsequent installation).

Turning the carburetor on the trimmer, remove it from the thrust of the air damn on the housing and then from the other traction.

In the new spark plug champion rcj6y (for Husqvarna), set a gap of 0.5 mm. Unscrew the old light of the ignition and install a new candle in the trimmer cylinder for the grass! (an old candle. either immediately throw it away, or clean, put a gap and cook to wash to hide in the reserve).

Possible causes of malfunctioning in electric braids

When operating a trimmer for the grass on which an electric engine is installed, there are also problems with a speed set. But they are called by completely different problems compared to fuel braids. The electric motor does not develop the required rotation speed in such cases:

  • if the voltage operating in the supply network is below the nominal value for an electric motor by more than 10 %;
  • in case of problems in the system of smooth start (if this unit is installed);
  • when there are problems with the brush knot;

In order to exclude The problem with the tension. It is required to check its size in a rosette by a multimeter or tester, from which power.cockers are taken. If it is less than the minimum acceptable value, then to increase it will need to turn off all electrical appliances or install a stabilizer.

A prerequisite necessary for the normal operation of a trimmer for grass is the use of an extension cord with a section of cores corresponding to the power of the braid engine for grass.

For repair of a smooth start unit You will need to have appropriate knowledge in electronics, so it is better to contact the service center. There will be determined with its maintainability or the need to replace. You can check the button on your own or find the block diagram and try to figure it out.

Щетки могут износиться, в результате будет пропадать контакт, что приводит к остановкам электродвигателя. Щетки заменить несложно. Особенности процесса определяются применяемой моделью мотокосы. Попутно также понадобится почистить все контактирующие поверхности.

В случае подгорания обмоток. если продолжать косить траву или кустарник, электродвигатель быстро сгорит. Это будет сопровождаться появлением запаха гари, вплоть до расплавления отдельных деталей. Понадобится провести замену электромотора.

Подклинивание вращающихся частей происходит по разным причинам. Для их выявления и устранения понадобится перебрать приводной узел. Встречаются модели, у которых количество оборотов автоматически регулируется в зависимости от нагрузки, увеличиваясь при ее возрастании — у них на холостом ходу скорость вращения падает.

На видео показан алгоритм действий по выявлению наиболее часто встречаемых причин, по которым триммер для травы не набирает требуемые обороты:

Что делать если не заводится двигатель?

Если не удается завести газонокосилку, то первым делом надо проверить наличие топлива в баке и его качество. Для заправки инструмента рекомендуется использовать качественный бензин, приобретенный на автозаправочных станциях, марка которого должна быть не ниже АИ-92. Экономия на дешевом топливе может привести к поломке цилиндро-поршневой группы, на ремонт которой может уйти треть от стоимости самой мотокосы. Не менее важно и правильно готовить топливную смесь из бензина и масла. Пропорциональное соотношение данных компонентов смеси указано производителем в руководстве. Не стоит готовить топливную смесь в больших объемах, так как при долгом хранении теряются ее свойства. Лучше использовать свежеприготовленную смесь.

При приготовлении топливной смеси масло заливаем в бензин с помощью медицинского шприца, позволяющего точно соблюсти необходимую пропорцию компонентов

Загрязнение топливного фильтра в баке может также препятствовать работе двигателя газонокосилки. Поэтому при возникновении проблем с запуском мотора проверьте состояние фильтра. При необходимости произведите замену фильтра. Запрещается входящий патрубок оставлять без топливного фильтра.

Также в проверке нуждается и воздушный фильтр. При загрязнении деталь снимается, в полевых условиях промывается в бензине и ставится на место. На даче или дома фильтр можно промыть в воде, используя моющие средства. После этого фильтр прополаскивается, отжимается и сушится. Высушенный фильтр смачивают небольшим количеством масла, используемого для приготовления топливной смеси. Излишки масла удаляются путем сжатия фильтра руками. Затем деталь устанавливается на место. Снятая крышка ставится обратно и закрепляется винтами.

Воздушный фильтр, промытый в топливной смеси, отжатый и высушенный, устанавливают на место в пластмассовый корпус и закрывают крышкой

Как делается данная процедура более подробно вы можете посмотреть на

Если все вышеперечисленные процедуры проведены, а двигатель не заводится, то отрегулируйте его обороты на холостом ходу, подкручивая винт карбюратора. В видеоролике, размещенному в начале статьи, этому вопросу уделяется внимание.

  • Инструмент положите на бок таким образом, чтобы воздушный фильтр находился вверху. При таком расположении бензопилы обеспечивается попадание топливной смеси точно в низ карбюратора. С первой попытки заведется мотор, если вы перед запуском снимите воздушный фильтр и зальете в карбюратор несколько капель смеси, после чего установите демонтированные детали на место. Метод проверен на практике.
  • Если первый совет не дает результата, то, скорее всего, проблема в свече зажигания. В этом случае выкрутите свечу и проверьте ее работоспособность, а также просушите камеру сгорания. Свечу, не подающую признаков жизни, замените новой.
  • Если свеча зажигания находится в исправном состоянии, фильтры чистые и топливная смесь свежая, то можно воспользоваться универсальным способом запуска двигателя. Закройте воздушную заслонку карбюратора и дерните ручку стартера один раз. Затем откройте заслонку и дерните стартер еще 2-3 раза. Повторите процедуру от трех до пяти раз. Двигатель обязательно заведется.

Некоторые с такой силой дергают ручку, что приходится производить ремонт стартера газонокосилки своими руками. Это возможно только в случае порыва тросика или поломки ручки троса. В других случаях рекомендуется проводить замену стартера. Данный узел продается в сборе.

Как правильно заменить свечу зажигания?

Как видите, ничего сверхсложного в данной процедуре нет.

Новая свеча зажигания для двухтактного двигателя внутреннего сгорания бензиновой косы для травы устанавливается взамен старой детали, вышедшей из строя

При открытии воздушной заслонки

Случается, что агрегат глохнет при открытии воздушной заслонки, нормально работая на холостом ходу. Это связано с подсосом воздуха системой, вызванного наличием трещин топливного шланга

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.

Low quality fuel use

The benzotrimer does not gain speed in case of poor.quality fuel. He may stop or not start at all. To check the quality of the fuel, you need to inspect the candles. They are the main indicators for solving problems with the combustion chamber.

The mower does not develop revolutions and stalls, causes and repairs

In the presence of sediment, a raid, plaque, the old fuel merges, and another, high.quality.

or gasoline cutter should be filled with good quality gasoline and the fuel brands that the manufacturer indicated in the technical passport of the device.

For your information! Candles should be thoroughly cleaned of plaque, and only after that they are again placed in the combustion chamber.

Engine starting problems

It is very important to determine the cause of the failure correctly, because otherwise we simply cannot eliminate it. If there are no extraneous sounds when trying to set up a chainsaw (knocking down, grinding, etc. D.), It often turns out that in fact there are no problems

For example, if you put the chainsaw and pull the fork for a long time, the engine simply pours and starts very much

D.), It often turns out that in fact there are no problems. For example, if you put the chainsaw and pull the fork for a long time, the engine simply pours and starts very much.

To properly start the engine saw engine, set the lever or switch to the “flap” position. Then you need to pump the mixture into the carburetor if there is a fuel pump in stock. Pull out the starting handle until the engine resistance becomes noticeable, and energetically extend the amplitude, taking your hand to the side. After two. Three such movements, the engine must first start, and then decay. If this does not happen, then it is necessary to transfer the lever to the position of half.gas or simply to the working position, and then continue to work the chainsaw in this mode. Many Pologaz chainsaws are recorded automatically when the air damper is pulled

Some models have an ignition with the key, it is important to make sure that it is turned on

If the engine does not start, the first thing to do. unscrew and check the spark plug. There are times when the plant fills the burner with fuel in the cold season. Then you also need to unscrew the candle, dry the combustion chamber with one plant, clean the spark plug, screw it up and repeat the start. It is advisable to immediately check the presence of a spark. On a twisted candle, we put on a cap with a high.voltage wire, we put it on a cylinder, and we pull the starter. Visually observe a frequent blue spark. OK. We twist the candle in place and launch it. If there is no spark, change the candle and repeat the attempt. Again, no. Check the connection of the high.voltage wire to the spark plug, coil and ignition system.

In general, the condition of the candle can be used to determine the type of malfunction.

  • Dry. Most likely, the fuel mixture is not included in the cylinder. This is not a ignition system, so the candle is screwed and checked.
  • Wet, strongly sprinkled with fuel. The cause of the excessive fuel mixture is to violate the launch rules, as described above, or if the carburetor is incorrectly set up.
  • Covered with black carbon. This may indicate the use of poor.quality oil, an incorrectly configured carburetor or an incorrectly calculated ratio of gasoline and oil. The candle should be washed, cleaned of carbon deposits with a sharp object (awl or needle), rub the electrodes with a fabric and installed in place.

When checking the light of the ignition, it is necessary to pay attention to the gap between the electrodes: Normal is considered from 0.5 to 0.65 mm. Damaged or worn gasket should be replaced. Correctly adjusted carburetor chainsaw provides its effectiveness at full capacity with the most economical fuel consumption

Correctly adjusted carburetor chainsaw provides its effectiveness at full capacity with the most economical fuel consumption.

The need for tuning a carburetor chainsaw is infrequent, since adjustment is originally performed by the manufacturer to achieve the optimal mode of operation. Adjusting screws are designed for a more accurate adjustment of the carburetor chainsaw, if necessary.

Among the causes of violation of fixing the adjusting screws are the most common:

  • Strong vibration or damage to a protective cap. This rarely happens, but still happens.
  • Serious engine wear (piston). Of course, in this case it is better to take care of repairing a chainsaw, but at the same time, adjusting the carburetor can improve its functionality for some time.
  • Litter in a carburetor because of the low quality of gasoline or due to the formation of scale. In this case, in addition to adjusting the carburetor, it can be avoided.

The lawn mower stalls

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

But do not immediately run to the service center and pay big funds to the craftsmen who convince you of the presence of severe malfunctions in the device.

The lawn mower stalls at high speeds

Perhaps more and more a widespread complaint associated with gasoline trimmers sounds like this: “The lawn mower stalls”.

Naturally, a rather harsh fault may be a prerequisite for this. A two.stroke trimmer engine for grass does not develop turns stalling. lawn mower FS 130 give gas stalls. But in most cases, the situation is even easier than it seems to be the 1st gaze.

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

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

Why is a Chinese lawn mower not developing momentum?

The trimmer for grass does not gain momentum, a very common inconsistent and of course does not always have a common solution.In this.

The lawn mower is not gaining momentum, the cause of the malfunction and eliminate it

1st launch of the latest lawn mower.Removed the grid from the silencer, began to work.

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

In this case, the lawn mower will stall at idle. At speed stalls a trimmer for Champion grass. GAPHOLLOSKALL GOODLUCK 4300 stalls video revolutions. The lawn mower stalls when you press the gas. At high speeds, the lawn mower stalls. 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.

Carburetor device Motokos Chinese

Today, the question is relevant and open, what is briefly formulated as follows: carburetor motorcosa device. And if European and American production professional lawnmands in their instructions contain statements about setting up a carburetor, then the scheme of this element of a braid of Chinese.made grass is not yet available to a wide circle of users. In this article we will try to figure out: what is the special carburetor of the lawn mower, the country of which is China and how it differs from those, for example, which stand on the original Husqvarna, Stiles and, for example, Oleo-Mac, produced not in the PRC, but purely in Italy.

This unit will optimally paint by individual elements, and here we will indicate the difference from other types of carburetors of this copy:

  • Fuel pump of a membrane type.
  • Adjusting system with atmospheric membrane.
  • Idle system.
  • Dosage system with quality screw.
  • Primer (popularly “podok”). helps to develop all fuel from the tank, and also facilitates the launch if you have not used the tool for a long time.
  • The main detail is an elastic plate of complex shape, it contains two valves.
  • The needle valve similar to the car. this is the adjustment system. When the pressure decreases, it closes with a special membrane. In the first photo. the second connector from the body, on the left.

Features of the device of the carburetor of the Stihl lawn mower

The diagram of the carburetor motor.cooker manufactured by the German company StiHL differs from the Chinese similar mechanism already in that it provides for manual tuning by the user. For this, screws L, h, t are installed here. If the protective cap of motorcycles is damaged, then they can unscrew and then the work will become disarmed. Problems can be quickly eliminated by returning a certain screw to the previous position. The same situation comes from excessive vibrations of the entire gas.trimmer apparatus. On the carba of a Chinese mowing, as a rule, only one screw is to regulate the idle.

Almost, any correction of the work of the carburetor of the braid for the grass of the Stihl FS 55 brand can be carried out independently using your hearing or a special device. a tanometer. You need to check only after the engine warms up. From the cognitive video, you will draw a useful information about the carburetor. For productive operation of the braid mechanism for grass, we will always offer high.quality, but cheap oil for the compressor, as well as any other accessories and spare parts.

The principle of operation of the carburetor of the lawn mower

The throttle dashes determines the amount of air for supply, and the engine power directly depends on this.

Fuel is sucked into the carburetor system (its membrane). Then passes through the fitting in the carburetor. Next, the liquid moves through the intake and exhaust valve of the pump. Filtered with a net. The needle valve moves into the membrane chamber.

  • Air supply to the tube with an air septum (damper). The partition regulates the intensity of the air flow.
  • The fuel supply system is necessarily narrowed by a diffuser to increase the flow rate.
  • Gasoline through the float chamber and nozzle with narrowing. The chamber with a float regulates the temporary volume of gasoline. In the float chamber, the pressure level is neutral, and in the tube with narrowing is already low. Thanks to the pressure drop, fuel penetrates through the jetler.
  • Air flow acceleration contributes to the transfer of fuel (gasoline) and its spray. As a result, the air-fuel mixture of the necessary proportion or density is formed.
  • The air-fuel mixture penetrates the engine cylinder through the fuel tube.

The level of air density in the system depends on the area of ​​the open air damper. The wider the damper is, the greater the fuel consumption and power.
