The lawn mower at large revolutions stalls the reason. Diagnosis and elimination of electric motor problems
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.
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.
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.
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.
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 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.

Common Reason for Honda Lawn Mower NO START | GCV160 Engine Auto Choke Repair
Apart from time to time, from time to time, 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 to use the braid by loosening the gas tank cover. If in this mode the device is working on a dull way, clean the valve.
over, the lawn mower can stall due to the disgusting receipt of fuel in the carburetor. Nevertheless, repair t.e. It works normally at low speeds. Why then the device starts up, ask you? The reason for this is that at first, the fuel gradually runs into the carburetor and is enough to work at high power. The lawn mower does not work at idle. But then it is produced and at huge turns the engine begins to stall. As for the carburetor, here the problem may also consist in the fact that its body is very pulled.
In addition to everything else, do not forget to check the fuel intake hose. The inconsistent may be that it holds weakly or in general cracked.
These are the main prerequisites why the lawn mower can stall.
On the pages of the global network, you can find information that the chainsaw of the Stihl 180 can stall due to severe air filter pollution. I would like to refute this not absolutely true information, and say that the STIHL carburetor MS 180 is equipped with a compensator, which is designed and installed in order to make an air focus necessary for the usual operation of the Stihl 180 chainsaw, bypassing the dirty filter. Of course, the power with a clogged air filter will fall a little, but it will definitely not stall. Another capacity may fall due to the wear of the piston, here the repair of the piston chainsaw of the Stihl MS 180 will already be required.

- work of the sensor of the position of the trissellain;
- Injector or carburetor pollution
The grounds for breakdown can be completely different, therefore, when eliminating them, it will be necessary to operate with all kinds of actions and techniques. If your shoulders are considerable driver’s experience, and you know the features of the car’s work as your five fingers, regardless of the model, then the elimination of this kind of malfunctions will not cause you any problems. And all because such breakdowns are not complex or serious. It follows that you can establish the operation of the car without outside help. Well, if the level of awareness or lack of free time will not give you the opportunity to eliminate all defects yourself, it is better to seek help from knowledgeable people who can save you from unpleasant moments in the shortest possible time.
What could break
Problems with a benzocosa associated with the fact that this device is not started, specially classified by specialists of service services. They stand out malfunctions with subsequent nodes of the mechanism:
- the engine, in which the piston and bearings can be worn out or out of order, crack the crankcase;
- the fuel supply system, with all this, can be clogging the filter or difficulties with a carburetor;
- mechanical damage to wires, tubes, hoses;
- The ignition chain.
When working idle
Having launched a trimmer for grass or a motorcycle at idle, you find that the device is starting up. but it swallows, after working, say, 5-10 minutes. The prerequisites here can be subsequent:
- clogging, violation of carburetor adjustment;
- Initially, incorrect configuration of the valve mechanism of the carburetor;
- air filter clogging;
- reducing the speed of the gearbox (if any). the incorrect ratio of fuel.air consistency;
- clogging the throttle;
- penetration of excess air into the fuel system;
- The fuel ends in the tank (and oil in the tank, if the engine is four.stroke).
In the presence of troubles specifically with the carburetor, the machine will stop both after a cool start and after starting on the already worked engine.
The lawn mower stalls at high engine speeds
During operation, a situation arises when, when pressing the fuel supply key, the aggregate turnover begin not to increase, but to decrease. A malfunction of this nature can be caused:
Fuel hoses Motokos with filter
- etching of atmospheric air into the combustion chamber;
- problems with the circulation of a mixture of fuel;
- clogging the saapun in the lid of the fuel tank (cleaning the hole with a thin sewing needle);
- Incorrect carburetor adjustment.
When air sunses, when I operate ICE, it is necessary to check the tightness of the pipes and the integrity of the gaskets in the CPG. The problem with the circulation of the fuel mixture can be solved by the elimination of blockages in the fuel pipes leading to the carburetor. If a vacuum occurs in the tank and not receipt of the fuel mixture to the carburetor, it is enough to clean the soundtress with a thin needle and blow it with air.
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.

Huter gas mower adjustment of carburetor
Tuning the carburetor of the chainsaw of the chainsaw for an independent option of the carburetor, it is necessary to familiarize yourself with its device and understand the work order that is carried out to adjust the parts responsible for the correct functioning of the components of the device and the parts close to it. It is necessary to carefully handle objects for the option, also determine the compliance of the displayed characteristics of very acceptable values. About the device of the carburetor carburetor 
How to correct the fishing line for a trimmer to a gas station
A step.by.step annotation, how to wind a fishing line for a trimmer on a trimmer coil for grass with the advent of spring, you often spend your time in a dacha or a personal plot. From such a confusion as grass and weeds, you will be protected by a trimmer for grass. This tool without much work trims and mows grass in complex areas, where an ordinary lawn mower is not possible. Trimmer for grass. very effective and 
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.

The hole in the fuel cover (saepun) of a trimmer for grass
With a similar problem, it is worth paying attention to the fuel valve, which, when clogging, ceases to normally pass the fuel mixture. By solving this malfunction, it is weakening using a suitable tool. In addition, the problem with the circulation of the fuel mixture may cover in the contamination of the valve. To do this, just blow it with a stream of compressed air.
If you stalled when opening the damper
If the technique works properly at idle, but stalls when opening an air damper, this reports about the penetration of air into the system through cracks in the fuel supply hose or damaged oil seals. To fix the breakdown and establish the work of the tool without driving air from the atmosphere, it is necessary to replace damaged parts.
Another possible reason for the breakdown is the malfunction of the carburetor dosage system. To eliminate this problem, it is better to contact professionals.
Immediately after you started
The unit may stall immediately after starting, if the carburetor is shifted or incorrectly adjusted. This causes an uneven supply of fuel. As a result, the device vibrates clearly. To eliminate defects, the carburetor is reconfigured, following the annotations to the mechanism.
Apart from that, the engine stops when clogging the fuel supply valve. In such cases, it is quite easy to clean it. If the bureau at first earned, but later stalled immediately, then maybe the fuel with some difficulty falls into the carburetor knot. Weakening of the valve helps to solve the issue, which ensures free circulation of the consistency in the system.
The stop can also be caused by air leaks in the presence of mechanical damage to the hose (holes, cracks), taking fuel. In this case, increase the speed of the drive in order to resign more air from the system from the system.
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 comply with 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
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.
