Trimmer for grass does not jerk from the button reason. Benzotrimmer does not develop full power – which is wrong

Repair of an electric trimmer for grass

The electric trimmer for the grass replaced the usual spit. Today, most urban residents do not even know how to use a “rare” tool correctly. A modern person does not need this, because he has an electric counterpart. But if an ordinary braid had to just sharpen from time to time, then things are more complicated with the power tool. Equipment requires a certain care, and if a malfunction occurs, the repair can lead to big expenses. However, it does not always make sense to carry the failed tool in the workshop: often you can cope with the breakdown on your own.

To understand what exactly can break in an electric cost, first you should figure out how it is arranged.

Ethletric trimmer for grass usually consists of the following elements:

The current is supplied to the power unit through the connector on the case, to which the cable is connected. Inside the rod is hollow. it plays the role of a protective shell for a flexible shaft, transmitting torque from the motor to the coil of the trimmer for the grass. The handle located on the case has a button, when pressed on which the device turns on.

The described design is considered a classic. However, there are options for executing the tool in which the motor is located in the lower part near the coil, as well as the battery versions.

Repair of an electric trimmer for grass with your own hands: Frequent causes of breakdowns

One of the scenarios in which the tool is out of order is the mowing of a very neglected area. In this case, the equipment is affected by increased loads and often fails of the power unit. A breakdown of bearings or coils is also possible.

And when work is carried out in rainy weather, electrical equipment can simply close. Also, do not forget about a certain resource of individual assemblies of the tool, which are not designed for constant use. The device requires timely inspection with the replacement of worn parts.

Repair in some cases can be carried out independently, without the involvement of specialists, the cost of which is often considerable.

Repair of the launch button

If the tool does not respond to attempts to turn it on, two options for a malfunction are possible. a cable break inside the handle or the failure of the inclusion button.

Important! Make sure that the device is disconnected from the network if it is a stationary type. In the case of the battery version of the instrument, the power terminals should be first disconnected, and only then proceed to repair.

In order to understand what exactly the breakdown is, you need to disassemble the handle.

Having gained access to the inside, you should, armed with a multimeter, measure the resistance of the button. If it is absent after pressing, the button must be replaced.

You also need to check the contacts of the connection of the power cable with the contact group. Often the need for such a measurement disappears, t. to. The cliff can be found with the naked eye. In this case, it must be eliminated by soldering.

In the absence of a multimeter, the same work can be done using an indicator screwdriver. To do this, after disassembling the body of the power cable handle, it is connected to the network and the phase is checked by a screwdriver before and after the button. If zero comes to the button, the fork in the outlet can be turned and measured again.

Attention! You should be very careful when checking the presence of a phase in this way. There is a possibility of gaining electric shock!

Checking the electric motor

If the button and cable that feeds the tool will be serviceable, you should go to the diagnosis of a power unit. To do this, disassemble the case in which it is located. It is usually necessary to simply unscrew several bolts or screws and remove the lid.

First of all, you need to check the condition of the collector brushes. The wear of this node can lead to unstable operation or to a complete stop of the engine. If the brushes are in satisfactory condition, you should check the winding of the motor for a short circuit.

For this operation, it is necessary to completely remove the engine, and then check all the collector plates in the mode in the mode. The device should not show significant deviations in measurements.

The second check is the “ringing” of the rotor winding to the “mass”. To do this, you need to connect one of the multimeter contact to any collector plate, and the second to the “mass” of the rotor. In this case, the resistance measurement mode should be more than 1 MOM. If there is no short circuit, the device will show a very large meaning.

If, according to the results of these checks, all the parameters turned out to be normal, you need to measure the resistance of the stator winding. Indications should be similar, as in the case of the rotor. If not, then the malfunction lies in the stature.

If there is an interval circuit in the engine, it will not be diagnosed in this way. However, this problem can be identified by observing the trimmer for grass in action. An indirect sign of such a malfunction will be a decrease in the power of the work and overheating of the equipment.

When, as a result of diagnosis, it became clear that the engine was “burned out”, it would be easier to notice it on a new. In the vast majority of cases, repairs, consisting of rewinding, will cost as much as a new power unit.

If the engine is installed on the engine, then it will turn off the power when overheating. If the problem is the malfunction of the relay itself, this can be identified using the same multimeter or tester. With a cold engine in good condition, the relay should pass the current.

Mechanical malfunctions

Such problems include a breakthrough of the flexible shaft. It is easy to recognize it. the motor works, and the coil with a fishing line does not rotate.

The reason for the breakdown is the unfair care of the tool, which consists in the timely lubrication of the inside of the bar. In the absence of the desired amount of lubrication, the shaft will be subjected to excessive friction and the cliff will become a logical result.

trimmer, grass, does, button

This breakdown is corrected by replacing the shaft, which can be removed by disconnecting the upper part of the trimmer for the grass from the bar. If the second part of the shaft is not extracted, disconnection and lower.

When installing a new shaft, it should first be lubricated.

Such a malfunction can occur only with a classic layout of parts. In devices where the power unit is located in the lower part, there is no flexible shaft. However, with such a layout, the role of the gear ratio is played by a bearing located on the engine shaft closer to the place of transmission of the moment. In this situation, the bearing must simply be replaced with a new.

The reasons why it is impossible to start a motorcycle

These are the reasons why the motor motorcycus cannot be made:

  • In the fuel tank, an old exhausted gasoline;
  • the engine starting procedure is disturbed;
  • short circuit of the wires going to the on/off button;
  • the ignition system is faulty;
  • clogged air filter;
  • Fuel filter clogged;
  • fuel hoses;
  • Board of the sapun;
  • Parus is a primer;
  • Cutted with mud or faulty carburetor;
  • The air damper drive broke;
  • The engine is faulty (rings lay down).

In the fuel tank, old exhausted gasoline

Despite the fact that in the instructions for the operation of each model it is recommended not only not to leave fuel in the gas tank, but also to carry out the conservation of the engine, some of the owners of such equipment neglects these recommendations.

If the gas tank cover is tightly closed and the buttonhole valve is serviceable, then gasoline evaporates minimally during the storage, but any leaks worsen the quality of fuel.

After all, volatile hydrocarbons evaporate, and the remaining liquid absorbs water from the air. As a result, the combustibility of gasoline in the tank is insufficient to ignore the spark of a candle, so it is impossible to start the motor.

To correct the situation, it is necessary not only to drain the old fuel from the tank, but also to remove it from the carburetor.

This can be done in two ways:

  • remove the carburetor, disassemble it and drain the remnants of gasoline;
  • To pump up new fuel with a primer, and then, tens of times twitching the starter cable, pump the old gasoline through the combustion chamber until the new fuel appears there, then dry the candle.

The first method is more difficult technically, because not everyone can correctly disassemble and assemble, as well as install a carburetor in place, and then connect it.

The second method requires high endurance and patience, because you have to pull the cable for more than one minute, while choosing a free move each time, because if this is not done, then you can damage the starter mechanism.

The engine starting procedure is broken

In the instructions for the operation of each model of a trimmer for grass, the engine starts the engine, both after winter storage or purchase, and during operation.

In addition, you will find universal instructions for launch in this article. Violation of the recommended order often leads to the fact that the owner of Motokos cannot start his device.

In this case, we recommend:

  • the instructions or an appropriate article;
  • dry the candle (often during the wrong launch it is filled with gasoline or fuel mixture);
  • start a trimmer for the grass in a regular way.

A short circuit of wires

To turn off the engine, the switch connects the wires suitable for it and shunts (closes) the ignition system for low voltage.

Under the influence of vibration and due to the use of wires with poor-quality isolation, the latter sometimes grows out, which can lead to a closure.

Such a short circuit performs the same function that the trimmer button for the grass is turned off the “turned off” position, so the manipulation of the button does not give any result.

To diagnose damage, remove the wire of the inclusion system button from the terminal terminal (on some models you will have to be cut or dropped out), then measure the resistance in the “inclusive” and “off” tester between this wire and engine body.

If the button and wiring are working, then in the “inclusive” mode the resistance will strive for infinity, and in the “off” mode will show a short circuit.

If the wiring is damaged, then:

  • disassemble the working handle;
  • Saving or cut the wires suitable for the button, as well as to the ignition system and the engine;
  • Pull the old wires and insert new instead;
  • Sold or connect new wires using terminals;
  • Collect the handle.

The ignition system is faulty

Here are the main malfunctions of the ignition system:

The wrong gap between the magneto and the ignition coil

Two magnets were inserted into the aluminum flywheel of the engine. When the motor works, the flywheel rotates and the magnets pass by the ignition coil, forming in it the pulses of the electric motor (EMF), and two magnets provide 2 times more energy than one.

This energy is stocked in the condenser inside the ignition unit and after the passage of the second magnet the accumulated energy in the form of a single pulse enters the transformer, which is the ignition coil.

The effective exposure of magnets is possible only at a small distance, so the ignition unit is fixed reliably, but the flywheel is installed in the high temperature zone, and its ribs create an air flow, blowing the motor.

Therefore, many motos models provide for the possibility of adjusting the gap between the flywheel and the block.

If the ventilation holes of the casing are clogged, then the temperature of the flywheel becomes too large, which leads to a stronger temperature expansion and the flywheel begins to cling to the ignition unit.

This leads to the appearance of a much stronger vibration, which is why the block is moved away from the flywheel under the influence of strikes, which leads to an increase in the clearance in the cold state.

And the larger the gap and less the speed of the coil through the magnetic field, the lower the EMF, which means less spark energy, which leads to a difficult or impossible launch “for cold”.

The optimal gap between the core of the coil and the flywheel magnets is 0.2 mm, about the same thickness at the wall of plastic bottles of sweet or mineral water.

Therefore, for diagnosis, make a probe from such a bottle, cutting it down, then the probe will curl and tighten the flywheel, or you can use a probe to adjust the heat clearance of valves.

Other malfunctions and their causes

In this section you will find recommendations that will help you determine and eliminate the problem if the trimmer for the grass has stopped starting.

We have collected here the most common malfunctions, as well as a list of possible reasons that lead to them.

This will help you quickly conduct a check and determine the real reason why the lawn mower stopped starting.

There is a spark, and a candle is dry

If you checked the spark with a discharge and it pierced a distance of 1 cm, then change the candle, and if this does not help, look for why the fuel does not enter the combustion chamber.

After all, if it had been received, then the motor would work, and with an excess of fuel, the candle would be wet.

If there is a spark, and the candle of the lawn mower is dry, then to establish the cause, do the following:

  • Check the fuel hoses and filter;
  • Check the primer valve;
  • Check if the carburetor is clogged;
  • Look for air leaks.

Having discovered the problem, repair or replace the damaged part.

There is a spark, and the candle is wet

If the discharge showed that there is a spark of sufficient power, but the candle is wet, then there is too much gasoline or too little air in the combustion chamber of the lawn mower.

These are the possible causes of such a malfunction:

  • faulty candle;
  • exhausted gasoline;
  • Dirty air filter;
  • a layer of soot on a candle;
  • Air damper jam.

Conduct diagnostics as described above, then eliminate the problem.

The candle is wet

If there is nothing to check the spark, then to all the possible malfunctions described in the previous section, add the problems of the ignition system. Then conduct a full check of all the trimmer systems and devices for the grass, because the reason may be anywhere.

Do not start “on hot”

If a benzotrimer is poorly started or not started “on hot”, then possible reasons:

  • Dirty air filter;
  • the ventilation holes from the hand of the manual starter are clogged;
  • The wrong gap between the flywheel and the ignition coil.

Check all systems and details as described above, and also adjust the gap between the flywheel and the ignition unit.

Not starting “on cold”

These are the possible reasons why the benzotrimer is poorly started or not started by the “cold”:

  • fault of the air damper drive;
  • air leakage;
  • Primer faulty;
  • too much gap between the flywheel and the ignition unit;
  • scored sapunes;
  • Piston rings lay down.

Check everything as described above, then eliminate the cause.

Badly starts in all modes

  • Dirty Sapun;
  • old fuel;
  • air leakage;
  • dirty candle;
  • The wrong gap between the flywheel and the ignition unit.

Check everything as described above, then eliminate the cause.

There is no spark

If there is no spark, then the possible causes of the malfunction are the following:

Starts and stalls immediately

Check everything as described above, then eliminate the cause.

We suggest watching a video that describes the reasons why the electric trimmer for the grass does not turn on and recommendations on what to do if the device does not work:

If an ethletric trimmer does not work or disconnects during operation, then there may be many reasons for this.

After all, the normal functioning of this device is provided by:

  • mechanisms and electrical equipment inside electrocos;
  • Udlier cable;
  • socket;
  • house wiring;
  • Local line for power transmission (power transmission line).

Therefore, it is necessary to look for the causes of the inoperability of the tool both inside it and the rest of the participants in the electric circuit, in which it is the end consumer of electricity.

At idle

At single speeds, the common reasons for stopping a trimmer for grass are as follows:

  • reducing the speed of the gearbox when heating it, which is a consequence of the use of inappropriate fuel mixture;
  • clogging of the throttle;

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

Immediately after you started

The unit can stall immediately after the launch, if the carburetor is sipped or incorrectly configured. this causes an uneven supply of fuel. The result is that the device begins to vibrate clearly. To eliminate problems, the carburetor is reconfigured, acting according to the instructions for the mechanism.

The engine also stops when the valve supplies fuel clogs. In such cases, it is enough just to clean it. If the lawn mower at first earned, but then immediately stalled, then possible fuel to the carburetor unit enters some difficulty. The weakening of the valve helps to solve the issue, which provides free circulation of the mixture in the system.

The stop can also be caused by air leaks in the presence of mechanical damage to the hose (holes, cracks) that fuel fuel fuel. In this case, the drive should be added to the drive to quickly drive air bubbles from the system.

If the lawn mower suddenly stalled, but there is gasoline in the fuel tank, then there is a problem that violates the operation of the motor and leads to its stop.

Understanding the principles of the work of such technology and knowledge of the main reasons leading to the stop of the power unit will help you quickly determine why the motor has stopped functioning.

In addition, you can eliminate part of the reasons at home, because now you understand what and how it affects the operation of the motor, as well as how to carry out repairs.

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.

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.

trimmer, grass, does, button

The starter of the starter is 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 causes of the malfunction

In the first case, you will need to replace the case, handles, knives and wheels with lawn mowers. When the blades are blocked, the block stops mechanically. Such damage is associated with an attempt to mow hard or high grass. Repair of the lawn mower. This is to free the cylinder from stuck grass and scroll it the other way.

When using a lawn mower with a blunt or damaged knife, the grass is mowing unevenly. In this case, the device can vibrate or stop abruptly.

For the proper operation of the device, it is recommended to sharpen the knives with a file (angle 30 °). Otherwise, an abrasive tape is used. The gap should be between 2 blades regarding the strip. The device turns on periodically (within 15 seconds). If the blades are sharp, the strip is removed, the gap is regulated.

If the knives are not in the correct position, the law mower of a cylindrical shape makes sharp and uncontrolled movements. Typically, the gap between cutting elements should be thinner than a piece of paper. Otherwise, the clearance is regulated. It is recommended to first read the instructions for the operation of the device and disconnect the fork. If the connection is lost, a whistle will appear. The device vibrates and buzzes. Repair of a lawn mower means adjusting butt bolts.

If the belt breaks or stretches, it must be replaced. To do this, unscrew the screws. Then the pulley moves, the belt is removed. The new part is put on a small, and then a large pulley. The gear returns to its original position. The next step is to check the tension of the new belt. The deflection should not exceed 4 mm.

Faulty electrical models

The reasons for disconnecting the lawn mower are associated with a cord break or power outlet. In the first case, it is recommended to check the presence of a cable. To replace the power cord, disconnect the fork from the outlet, open and remove the circuit breaker cover.

Before unscrewing the cable clamping plate? You must remember the scheme for its connection to the switch. Use a hexagon (1 mm diameter) to disconnect the cord. The clip is released, the conductors are dismantled. The multimeter is used to check the presence of a cable. If necessary, install a new cord. In this case, the reverse sequence is observed.

In the second case, it is recommended to connect another device to the mains. Electric devices may not work if the fork is damaged. You will need to disassemble the fork for repair. To do this, use a screwdriver and tester.

Problems with the engine arise when overheating of the mower:

In the first case, it is recommended to wait a few minutes so that the engine cools down. In the second case, you must remove the stuck object. The effectiveness of the cooling system depends on the state of the air filter. Dirty device does not pass air, which helps to turn off the device. Experts advise cleaning and changing the filter every 3 months (with constant use of the lawn mower). If the engine fails, the corresponding smell and noise appear. In this case, you will need to replace the disk.

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.


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.

trimmer, grass, does, button

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!
