The trimmer for the grass works but does not mow the reason
If the lawn mower stops when pressing the gas, then the reasons may be the following.
- The most common option is a fuss of adjusting the carburetor, which occurs with significant loads on the drive, after a prolonged inaction of the mechanism or when it is used in severe conditions.
- The clogging of the fuel valve, which eliminates it with the message, as a result of which gasoline according to the system begins to flow normally.
- The weakening and hanging of the cable in the carburetor. Also, a tensile of the fuel hose can occur up to its rupture, caused by the action of a significant load.
- Clogging of the saapun (check valve), as a result of which fuel does not enter the tank.
If the problem is associated with the carburetor node, then it can be recognized by the appearance of vibrations of the lawn mower. Когда лопается шланг или растягивается трос — выполняют замену данных комплектующих.
Checking the ignition coil on the spark
It is necessary to pull the wire out of the trambler. After that, the wire must be brought to a metal element and rotate the engine with a starter. If there is a spark, then the ignition breeder is out of order. If it is not visible, you need to proceed to check the coil.
If the problem is in the trimbler, you need to start checking with its contacts. Problems can cause oxidation, probes in the insulating layer or rotor malfunction. If you notice problems with the rotor, it must be replaced with a new element.
During the diagnosis of the ignition coil, check the state of the winding. Typically, the absence of a spark is caused by a short circuit inside this part. If you find its signs, we advise you to buy a new coil and install it on the car. Also, the ignition coil can damage overloads caused by faulty high.voltage wires or spark plugs.
The coil check is performed as follows:
- The car should be in a dry room;
- It is necessary to remove the dirt from the lid of the spark plug-distributor and remove it;
- crank the crankshaft of the motor so that the contacts of the trambler are in a closed position;
- turn on the ignition and bring the high-voltage wire of the distributor to the metal part of the motor by 3-7 mm.
It will also tell you whether the ignition coil in the replacement needs. The most suitable option is to test the coil on special equipment in workshops. This procedure checks the work of the coil in different modes.
To check the spark on the candles, they must be unscrewed
Pay attention to the state of contacts, the presence of soot or oil. All mud elements must be removed even before the diagnosis. Do not forget about the correct gap between the electrodes
Do not forget about the correct gap between the electrodes
If a discrepancy has been discovered, the side electrode carefully bends. Like the coil, the spark plugs can be checked qualitatively only on special equipment

Why is the hydraulic distributor
Ring grooves cannot create 100% tightness. Also, dials of working fluid create conditions for normal lubrication of spools during operation! That is, in the design of any distributor, permissible leaks along the spools are laid. Someone has more, someone has less. Depends on the manufacturer. This is fine. That is, to “keep” the pressure of the working fluid (oil) under pressure in the g/c when locked the line associated with the working cavity of the hydraulic cylinder, the distributor will not be able to.
Therefore, in the g/system, where this is necessary according to the working conditions, the water.hazard is additionally installed.
For example, in the hydraulic systems of the KMU, the locks are installed on the g/cylinders of the autrigers (paws), g/c raises of the arrow, on the g/c nmings of the arrows.
Then if the hydraulic system is additionally installed in the hydraulic machine and the cylinder “sags” under load, the hydraulic distributor has nothing to do with. It can simply be excluded as a probable cause of falling.
Hydro.cylinder malfunctions: Causes and repair
Modern special equipment: bulldozers, excavators, lifts, taps, manipulators are equipped with hydraulic equipment. As it is operating, it wears out and fails. Although the hydraulic cylinders themselves are relatively simple, it is important that the repair is carried out correctly. Poor repair work will lead to damage or destruction of equipment, injuries or the death of people working nearby.
Electric trimmer for grass vibrates
Many mowing users noticed that some time after the start of the apparatus, it begins to vibrate very much. On some trimmers, mainly in models more expensive, an anti.vibration system was installed in the form of shock absorbers seized between the engine and the bar. But in some cases, even she does not save from strong vibration. The reason that strong vibration appears in the trimmer, there may be a small amount or complete absence of lubrication on a hard or flexible shaft located inside the rod of the apparatus.
Replacing the lubrication of the hard shaft is as follows:
- Apply a small amount of lubrication to the shaft and evenly smear it along the entire length of the part, including the slots at the ends of the rod (if they worked, the shaft will have to be replaced);
- After lubrication, insert the shaft back into the bar and put the gearbox in the same place.
The lubrication of the flexible shaft is as follows:
- unscrew and remove the mowing head;
- remove the bar from the electric motor by unscrewing a couple of bolts;
- Pull out a flexible cable from the bar;
- Lubricate the cable with grease along the entire length.
This is done like this: first you need to lubricate the end of the cable, and then insert it into the bar, after which, as it moves into the pipe, you should apply grease to the part and evenly distribute it on the surface. Then insert a bar with a flexible shaft into an electric engine and fix it.
In the event that the lubricant did not help, and the vibration continues to appear, you will need to change the flexible shaft.
The trimmer for the grass is very hot
Overheating of a trimmer for grass can occur for many reasons:
- Gasoline has not the same octane number indicated in the instructions for the unit;
- the proportions of gasoline and oil during the preparation of the fuel mixture are not observed;
- A mixture of fuel with butter has long been prepared (the mixture cannot be stored for more than 2 weeks);
- The trimmer for the grass works more than the time instructions;
- A low.power trimmer for grass on thick and hard grass is used, the device works with overload and quickly heats up;
- shifted towards the bar or the cassette lid clutched.
The latter occurs if you install a mowing head inappropriate for this unit, or when the axis shifts inside the bar. These changes make it difficult to rotate, the load on the engine increases, and it overheating.
Trimmer repair for grass for grass with your own hands: Frequent causes of breakdowns
A trimmer for grass may fail when working in conditions of increased loads. This situation may arise when the processed area is overgrown with high grass.

When working in such areas, the engine may fail, a breakdown of bearings occur, as well as the coil of the electric ships to collapse. When working in rainy weather or in conditions of very fog, a trimmer for grass can “burn” as a result of a short circuit formation.
Damage to this electrical device can occur as a result of frequent use. If the household appliance is used in this mode, then after the development of a certain number of motorcycles, it will be necessary to carry out mandatory repair and preventive setting of many parts of the electrical device.
Repair of the launch button
If the electric coser does not show signs of life, then perhaps there was a break in the electric cable inside the hull handle, or the button for turning on the electric motor is faulty.

In order to diagnose electricians, you need to disassemble the electrical appliance handle. The work is performed in the following sequence:
When access to the inner part of the electric ships is provided, using the multimeter, measurements of the resistance button for turning on the electrimmer are made. If there is no resistance after pressing, then this

In the absence of a multimeter, diagnostic work can be done with an indicator screwdriver. For this purpose, you should include a fork in an electrical network and using this diagnostic tool

Why does the lawn mower stall after starting?
After starting, the motor may stall if the carburetor is incorrectly configured or it has been resolved. On what signs can be understood that the reason really lies in this? Very simple, by vibrations that will be clearly felt during the work of a gas station. You can adjust the fuel supply with your own hands by completing everything that is written in the instrument operation instructions.
The motor can stall due to clogged fuel valve. The reason is eliminated by cleaning it. If the lawn mower started up, and then stalled sharply, then it is difficult to supply fuel to the carburetor. Weaken the valves of the carburetor to ensure the free approach of the fuel to it in the right amount.
With excessive air leaks, the engine may also stall. Add the engine speed so that air bubbles come out faster from the fuel system of the unit. Be sure to check the integrity of the fuel hose. In case of mechanical damage (cracks, punctures, etc.P.), replace the part.
How to clean and store a tool?
During the operation of the lawn mower, monitor the state of the engine cooling system. The channels available in the starter housing, as well as the cylinder ribs, should always be clean. If you ignore this requirement and continue to operate the motorcycle, then you can disable the engine due to overheating.
Competent care of gasoline scythe during operation allows you to use it for several seasons in a row without serious repair
Before cleaning, let the engine cool down. Take a brush with a soft pile and clean the outer surface from dirt. Cleaning plastic parts is carried out by solvents, including kerosene, or special detergents.
After the summer season, the lawn mower should be prepared for long.term storage. To do this, the fuel mixture is drained from the tank. Then the engine is launched in order to develop fuel residues in a carburetor. The entire tool is well cleaned of pollution and sent to “hibernation”.
As you can see, it is possible to repair the malfunctions of the household lawn mowed on their own. Service services should be contacted in case of serious breakdowns. In this case, the cost of repairs with the price of a new lawn mower should be correlated. Perhaps it will be more advisable to buy a new tool.
Why the lawn mower is not started: frequent reasons
The most common problems that can be eliminated with your own hands are:
- a malfunction of the power unit, as a result of which it will not start;
- Vibration of the bar, complicating normal work with the tool;
- overheating of the gearbox leading to emergency shutdown;
- a decrease in revolutions, as a result of which a braid for grass will cease to perform its functions;
- pollution of the starter grille, causing an increase in the temperature of the power part and the engine is turned off;
- clogging of the carburetor, leading to the early exit of the device;
- clogging an air filter, due to which the engine will constantly stall.
The above breakdown can be eliminated independently during the inspection of the tool.
REPAIR LABING THE LAW: What can be done with your own hands
Когда силовой агрегат не заводится, глохнет сразу же после запуска, в процессе работы слышны посторонние звуки, ощущается вибрация или перегрев, нужно понять, какая часть инструмента находится в нерабочем состоянии. Diagnostics can be performed independently. There is nothing complicated about it. The inspection process is divided into stages, during which it is checked:
- lubrication of working elements and the presence of gasoline in the tank;
- serviceability of the spark plug;
- the condition of the fuel and air filters of the unit;
- graduation collector and sapunes;
- gasoline and lubrication quality.
Further, depending on the results of the diagnosis, you can either independently start repairing or call the master.
Checking and repairing the spark plug
If the fuel tucked into the tank is not in doubt, and the tool refuses to start when starting, possible, the cause of the breakdown is a candle.
- We twist and wipe the candle, then you need to dry it;
- We drain excess fuel from the chamber through the hole formed after twisting the candle;
- We dry the camera (about 40 minutes);
- we clean the twisted element from the carbon (for this you can use the file);
- We set a gap of 1 millimeter;
- Twist the candle in place and try to start the motor.
If after that the candle gives out a spark, but the engine does not want to start, you need to lubricate the thread of the candle with gasoline a little. If this does not help, then the cause of the breakdown is something else.
In the absence of a spark, there is a high probability of failure of the ignition unit. With such a breakdown, it will not work to carry out repairs, so you have to change the whole knot.
Filter malfunction
The lawn mower can also stall due to the clogged air filter. To identify this reason for the failure, you need to pull out the cartridge itself from the filter housing and start the tool. If a braid for grass works as usual, then the filter is subject to replacement or thorough cleaning.
In addition to air, the fuel filter can be closed. The check process is similar: we take out the cartridge and for a short time we start the tool.
Important! The work of a power unit without a filter element is fraught with an expensive engine repair. Such a check can only be carried out in exceptional cases and for the minimum periods.
Correction of problems with the saapoon and graduation channel
The saapun is designed to align the pressure in the gas tank. The most common breakdown of this element is clogging, as a result of which the tool begins to stall. Its repair is banal cleaning. For these purposes, you can use a regular needle.
The muffler is also at risk of clogging, which is often clogged due to dirt. In this case, the exhaust manifold is subject to cleaning, in which you can also remove an anti.icter net.
Repair of the carburetor
When checking the carburetor, you need to pay attention to its tightness. Diagnosis of this node is carried out in three stages:
- To exclude possible blockage in the fuel hose, it needs to be blown;
- In the case of a leakage of the unit, the replacement is subject to laying between the engine and the carburetor;
- Then the assembly and testing of the tightness of the system follows.
You can also disassemble the knot and clean all its elements with gasoline and compressed air.
Launcher of the starter and gearbox
The purpose of the gearbox is the transfer of the rotational moment from the shaft to the working part of the tool. The mechanism should be kept in complete cleanliness, as well as in a timely manner. It is possible to diagnose the correctness of this node if you check the tension of the cord, which is in the coupling with teeth of the gear ratio of the starter coil mechanism. These teeth tend to collapse at a sharp start.
The starter of the starter is not.free and must be replaced. From such situations in most cases, timely inspection and lubrication of the rubbing parts can save. To put such events is enough once a season.
Also, special attention should be paid to cutting elements. After completing the work, they need to be cleaned of dirt and grass. Regular inspection of the tool before use will maintain its performance for a long time.
The reasons that the trimmer for the grass does not develop momentum
External signs
The reasons are that the lawn mower is not gaining momentum, vary. Some are not even related to the breakdown of the device, for example:
- Getting on the filter of dirt or dust.
- Pouring low.quality fuel mixture.
- Using poor gasoline or overdue oil.
- Pollution of the engine components, which does not allow the instrument to gain momentum.
In the case of pollution on the carburetor, he sees a lot of soot. It is the reason that the trimmer for the grass does not gain momentum.
Internal problems that the gasoline trimmer for grass does not develop momentum
Technical malfunctions are manifested in both old and new devices. Do not be surprised. even a new trimmer engine for grass may not develop revolutions. Check the ignition system and supply of the mixture for serviceability:
- Когда коса для травы заводится и тормозит или даже не заводится, то проблема может быть в свече. A dark carrion appears on it. a sign of poor.quality gasoline and poor carburetor work.
- A flooded fuel hose is another problem due to which STIHL is not gaining momentum.
- With prolonged work without cleaning parts, a muffler can clog. Check the system for the presence of dark particles and clean the pipe, then the motor will start and start working as a new.
If the problem is in the motor itself and you do not know what else to do, be sure to take it to any master. You are unlikely to do something inside the motor, all the more right. And you will always have time to harm the device.
Serving parts of a benzotrimmer to prevent a problem
In order not to in vain to disassemble the motokos, it is worth diagnosing each zone separately. the problem can be in both one and several parts. Where to look and what to check.
Carburetor
One of the main nodes of the correct work of the trimmer for grass. So that the part functions as necessary, adhere to the conditions:
- Each month to remove and clean the part;
- Configure idle, according to the manufacturer’s instructions;
- If you yourself cannot set up. take the master.
One of the popular reasons for the breakdown of the motor. the carburetor cable is not pulled. To eliminate the problem, you need to disassemble the carburetor first, clean it, and only then tighten the cable. Just do not overdo it so that it does not pull like a string.
It is worth checking additionally: an intake needle, a membrane, a setting lever, a damper and other components of a carburetor. They may also have problems that interfere with the correct work of motorcycles.
Spark plug
Even if you don’t know what a normally working candle should look like, just remove it, dry it and clean it with sandpaper. Return the part to the place.
You can also check the distance on the main part. Maximum. 1 mm gap between parts of the fabric.
If the candle is too black, then there is no point in cleaning it. just buy a new one and install it on the motor. Then the whole system will work with new forces.
Filtering system
The blocking of an air filter can sometimes affect work even more than problems with the candle. To check if it is a problem. run the engine with the filter removed. If you started, rinse the filtration sponge in gasoline or other moisture. And you can buy a new one. this will only benefit your trimmer.
The clogged filters do not let the fuel mixture into the motor, so it stalls or does not start. The lack of gasoline can be fixed with banal cleaning: both a filter under the lid and the filter of the fuel hose (located inside the plastic tank for fuel).
Motor malfunctions
Internal combustion engine. the basis of the operation of the gasoline apparatus. What may be wrong with him if the motor does not gain power:
- The fuel mixture is incorrectly prepared, or its expiration date has long been released;
- The piston rings broke;
- Cylinder or piston in scratches and cracks;
- The device is used without breaks.
With the repair of the motor should be careful. This is because if you incorrect all the details, then you can stay like without a trimmer for grass, and also with injuries. Trust the case to a specialist!
