The lawn mower stalls with an increase in gas. Rules for the operation and storage of a lawn mower

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.

  • 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.

Diagnosis of malfunctions

All the prerequisites why the lawn mower is not started can be systematized by the specifics of the operation of individual units. The service center is systematized:

  • Motor malfunction (piston wear, bearing malfunction, crankcase crack);
  • Fuel consistency supply malfunction. clogged pores of an air filter or a malfunction of a carburetor;
  • the ignition system does not work;
  • A malfunction of a mechanical disposition. a leak of hoses, broken wires under a braid, rupture of the tubes.

The user first needs to check if there is a fuel in the tank. Starting in agreement with annotation, putting the saw on the side. Set the air damper to the position “Closed”, pump up fuel, turn on the ignition and produce 3-4 sharp jerks by the starter. STIHL 250 chainsaw when pressed on gas stalls, stalls, she worked on gas. If the engine has earned, open the air damper. Stihl 250 chainsaw when pressed on gas stalls, what. The lawn mower is not started. we repeat the operations with a slightly open air damper.

If you are unsuccessful, we begin to find the reason for the refusal:

  • check the quality of fuel;
  • make sure the operability of the candle and the cleanliness of the candle canal;
  • check the cleanliness of the air filter;
  • Make sure that the fuel filter is not clogged;
  • Check the cleanliness of the bastard;
  • Clean the exhaust channel.

complex reasons will be detected in the diagnosis of a malfunction, leading to the overhaul of the carburetor. Such reasons include clogging of the internal channels of the carburetor, wear on it gaskets and violation of the tightness of internal halls with a vacuum loss. DIY lawn mowing repair, if it does not start, will require patience.

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 figure out the reasons why the lawn mower is not starting up will help

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 cover just clogged or stick.

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.

In recent years, a gasoline trimmer for the grass has made the status of one book from the main tools in the arsenal of summer residents. And such an environment is logical, because a motorized braid for grass allows you to quickly put a personal plot in order. But with the form.

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:

lawn, mower, stalls, increase

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.

At high speeds

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

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

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

Malfunctions leading to improper operation of the chainsaw

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

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

What to do if the engine does not start?

If the lawn mower fails is not possible, then the first thing is to check the presence of fuel in the tank and its quality. For refueling the tool, it is recommended to use high-quality gasoline purchased at gas stations, the brand of which should not be lower than the AI-92. Savings on cheap fuel can lead to a breakdown of the cylinder-piston group, for the repair of which a third of the cost of Motokosa itself can take. It is equally important and correctly preparing a fuel mixture of gasoline and oil. The proportional ratio of these components of the mixture is indicated by the manufacturer in the manual. Do not prepare the fuel mixture in large volumes, since during long storage its properties are lost. It is better to use a freshly prepared mixture.

When preparing the fuel mixture, pour the oil into gasoline using a medical syringe that allows you to accurately observe the necessary proportion of the components

Fuel filter pollution in the tank may also prevent the operation of the lawn mower engine. Therefore, when problems with the launch of the motor, check the condition of the filter. If necessary, replace the filter. It is forbidden to leave the incoming pipe without a fuel filter.

The air filter also needs to be in the test. During contamination, the part is removed, in the field is washed in gasoline and put in place. In the country or at home, the filter can be washed in water using detergents. After that, the filter rinses, squeezes and dries. The dried filter is moistened with a small amount of oil used to prepare the fuel mixture. Excess oils are removed by compressing the filter with hands. Then the part is installed in place. The removed cover is placed back and fixed with screws.

The air filter washed in the fuel mixture, squeezed and dried, is installed in place in the plastic case and covered with a lid

How this procedure is done in more detail you can look at

If all of the above procedures are carried out, and the engine is not started, then adjust its revolutions at idle, twisting the carburetor screw. In the video posted at the beginning of the article, attention is paid to this issue.

  • Put the tool on the side so that the air filter is at the top. With this location of the chainsaw, the fuel mixture is ensured exactly into the bottom of the carburetor. On the first attempt, the engine will start if you remove the air filter before starting and pour a few drops of the mixture into the carburetor, and then install the dismantled parts to the place. The method is tested in practice.
  • If the first advice does not give a result, then, most likely, the problem in the spark plug. In this case, unscrew the candle and check its performance, as well as dry the combustion chamber. A candle that does not show signs of life, replace the new.
  • If the spark plug is in good condition, the filters are clean and fuel mixture, then you can use the universal way of starting the engine. Close the carburetor air damper and pull the starter handle once. Then open the damper and pull the starter 2-3 times. Repeat the procedure from three to five times. The engine will surely start.

Some pull the pen with such force that it is necessary to repair the starter of the lawn mowed with their own hands. This is possible only in the case of a gust of a cable or breakdown of the cable handle. In other cases, it is recommended to replace the starter. This node is sold in the collection.

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. Why does a lawn mower or a lawn mower stall when you press gas, at idle, when heated and other causes of non.taxes of a gasoline trimmer for grass. The cost of repair will cost about 70% of the cost of the product. The lawn mower stalls or a trimmer for STIHL grass stalls when why Chinese. To figure out the reasons why the lawn mower is not starting up will help

Why the lawn mower is not started, we eliminate problems

When caring for a personal plot, summer residents at times are faced with the fact that the lawn mower is not started. There are many circumstances of the instrument failure. A trimmer for STIHL grass is poorly started. For proper diagnosis of interference, the owner of useful in the country’s divetor should know the device and mechanism of operation of its individual parts.

Since the gasoline trimmer for grass refers to complex devices, before work you need to closely study the annotation for operation. Very often it is simply ignored, or they get acquainted with it superficially. As a result, when the tool stalls or renounces the question, the question arises. “why the lawn mower is not started

?»A long seasonal break in work, improper storage and untimely maintenance of a trimmer for grass, will deliver a lot of trouble to the summer resident, to eliminate the reasons.

Additional tips

First of all, what you should remember when acquiring this kind of tool is that certain details of the saw must be changed to new ones after their service life (passport) is over. It is for this reason that the instruction should always be at your hand, since everything is described in detail there in detail.

Such details include: asterisk (leading), tire, part of the system (anti.vibration), as well as a chain. Since do not forget that if this “filling” is not changed at a new time, then these worn spare parts will negatively affect the rest of the chainsaw. It is for this reason that quite often make a check of the depth of direct production of teeth. Remember that it should not be higher than a week 0.5 mm.

Muffler, as the reason that the saw stalls at the load

Here is another reason why the chainsaw stalls when pressing the gas. muffler. It is this part that can interfere with the full operation of the tool in cases where it is contaminated with directly exhaust resinent sediments. To do this, you just just need to clean it on.
