The causes of breakdowns of gasoline and electric trimmers

Trammer for grass, both electric and with an internal combustion engine (ICE), is an indispensable tool in the summer and autumn period for owners of cottages and private houses. With its help, weeds, small shrubs are easily removed and the lawn is trimmed. But, like any technique, trimmers for grass fail at the most inopportune moment. To eliminate the malfunctions with your own hands, the user of this technique first needs to determine the reason for their appearance.

In the lawn mower and an electric trimmer for grass, if you do not consider breakdowns associated with the bar and the mowing head, the malfunctions mainly happen in the engine area.

Damage of gasoline trimmers

Typical breakdowns of a gasoline trimmer for grass, which are most often faced with the owners of this unit, are as follows:

  • engine breakdown;
  • problems with the carburetor;
  • problems with the supply of fuel;
  • muffler malfunction;
  • gearal breakdown;
  • The starter broke;
  • Air filter problems;
  • Broken a buckshot on a gas tank.

Malfunctions of electric trimmers

Since the device of an electric coser is much easier than a motirmer, then there are few reasons for its failure.

It should be noted that the elimination of some of them is best entrusted to the specialist.

Basically, the trimmer for the grass ceases to work normally in the following cases:

  • Electric cable malfunction;
  • The control button is faulty;
  • burned engine winding;
  • Contact joints break on the engine.

Why is the gasoline trimmer not starting for the grass

The reasons why the gasoline trimmer for the grass stopped starting is different, therefore, a phased diagnosis of the apparatus is required.

Fuel tank (fuel quality)

Remember that always before starting the unit, a check of the presence and quality of fuel is required. In this case, you should not be greedy and save, as well as “clever” about the amount of oil added. Everything must be done according to the management attached to the apparatus, since when the piston group fails, its replacement will cost about 70% of the total cost of the trimmer for the grass. Pour fuel due to the fact that you will fully conside it when performing work. After a while, the gasoline remaining in the tank loses its properties and can harm the engine. Therefore, do not prepare the mixture for the future and in large quantities. If the lawn mower starts poorly, try to drain the “old” fuel from the tank, and season it with a freshly prepared mixture.

Important! To refuel the device with fuel, the origin of which is unknown, fraught with negative consequences. Gasoline should be of high quality, bought at a gas station, and its brand should be not lower than AI-95.

Candle and candle channel

So, you changed the fuel, but nothing has changed, and the trimmer for the grass still does not start. In this case, it is worth checking the candle channel: whether it throws it with a combustible mixture. Often users transfer the air damper to the “OFF” position when starting, and when the engine started, they do not transfer it to the “ON” position, after which it stalls. Further, an attempt to start the internal combustion engine to again leads to the fact that it floods the candle with gasoline, and the start becomes impossible. To diagnose and eliminate the possible problem in this node, do the following.

  • It is necessary to unscrew the spark plug, wipe it well and dry it. When installing a candle in the ICE cylinder, it should be dry.
  • Draw from the combustion chamber the fuel accumulated there. This is done through the hole from which you twisted the candle.
  • In the presence of soot on the electrodes of the candle, it must be removed either with a thin file or a nail file.
  • Do not forget to put the gap between its electrodes before installing the parts in place. The gap on the candle should be 1 mm. As a probe to check the gap, you can use a coin.
  • Next, collect the block, read the start instructions and try to start the engine again.

If the engine does not start, then you will need to check the spark. For this:

  • unscrew the candle;
  • put on it a cap of a high.voltage wire;
  • Touch its metal part to the cylinder body (to provide contact, you can insert a tubular key) as shown in the figure below;
  • pull the launch cord so that several engine speeds occur.

Normally, with each piston roll between the electrodes, the candle should slip a spark. If there is a spark, then the reason that the internal combustion engine is not launched should be sought in other nodes of the device.

For a better understanding of the process, how to test the candle for the presence of a spark, you can use this video where the check is shown by the example of the Lawn Mushiel “Soyuz”.

If there is no spark, then in the beginning check the cable connecting the candle to the coil. perhaps the reason is in it. You can call it with a tester. In case of detection of the rupture of the chain, a high.voltage wire will require a replacement.

Also the reason that the spark has disappeared is a malfunction of the ignition coil (magneto). The figure below shows what the coil (magneto) looks like from the gasoline trimmer for Patriot grass (Patriot).

To exclude the malfunction, it will be necessary to use a tester to check the Magneto trimmer for the grass, namely, its primary and secondary winding. On the primary winding, the resistance should be in the range from 0.4 to 2.0 Ohms. If the device shows 0. this means that there is a short circuit in the winding, and if infinity is a clear sign of a chain break. The resistance on the secondary winding should be in the range from 6 to 8 kOhm.

On some coils, it can reach the value of 15 kOhm.

Air filter

If your lawn mower does not start well or stalls immediately after starting, you should pay attention to the air filter, since it can be clogged, as a result of which the air does not enter the combustion chamber, and fuel ignition does not occur. To check if the filter is the case, remove it and try to start the engine. If he earned, then the reason was found. The filter needs to be replaced or rinse well and dry before installation. In the case when you find the oil in an air filter, it must be washed with gasoline, squeezed well and dry at least 2 hours before installing in place.

If the unit does not start with an air filter, it is still recommended to check the fuel filter.

Fuel filter

This filter cleans fuel of possible pollution. If it is scored, then gasoline does not enter the cylinder, and, accordingly, the unit does not work or stalls after starting. The fuel filter is located at the end of the fence hose, which is located inside the fuel tank. To get to the filter, it is necessary to extract a cork with tubes emerging from it.

When extracting traffic jams, a fence hose can disconnect and stay in a tank. It is extracted with a tweezer.

Next, remove the old fuel filter from the hose and put on it a new, pre.acquired. You can also clean the fuel filter if you do not have new. The filter must be fixed on the hose using a spring latch.

Install the fence tube on the cork and insert the last into the tank.

Settings Motokos Tatra

Fundamentally! To refuel the device with fuel, the origin of which is incomprehensible, fraught with negative consequences. Gasoline owes high quality, acquired at the gas station, and its brand may not be lower than AI-95.

What you need, you changed the fuel, but nothing has changed, and the trimmer for the grass does not start in any case. It is worth checking the candle channel here: whether it throws it with a combustible consistency. Often, users transfer the air damper to the “OFF” position when starting, and when the engine started, they do not transfer it to the “ON” position, after which it stalls. Further, an attempt to start the internal combustion engine again in order to fill the candle with gasoline, and the start becomes impracticable. To diagnose and remove the likely deed here, do the following.

  • You need to turn out the spark plug, wipe it perfectly and dry it. In the process of installing a candle in the ICE cylinder, it is desirable to dry.
  • Drain the combustion of the combustible fuel from the combustion chamber. This is done through the hole from which you turned the candle.
  • In the presence of a carrier on the electrodes of a candle, it must be removed either with a narrow suprafil or a nail file.
  • Do not forget to put the gap between its electrodes before installing the part to the area. The gap on the candle should be equated with 1 mm. A coin is used to check the clearance for a probe.
  • Next, collect the block, read the launch annotation and try to start the engine again.

If the engine does not start, then it will be necessary to check the spark. For this purpose:

    ;

  • put on its surface a cap of a high.voltage wire;
  • Touch its iron part to the cylinder body (to provide contact, of course to stick a tubular key) as shown in the figure below;
  • pull the launch cord so that several revolutions of the motor.

Normally, with each piston rolling between the electrodes of the candle, the spark should skip. If there is a spark, then the reason that the internal combustion engine is not launched should be found in other nodes of the device.

For the best awareness of the process, how to test the candle for the presence of a spark, use this video where the check is shown on the example of the Lawn Mushiel “Soyuz”.

If there is no spark, then first check the cable connecting the candle with the coil. it may be the reason specifically here. You can call it with a tester. If the passage of detection of the rupture of the chain, a change of high.voltage wire will need.

Also, a prerequisite for the fact that the spark has disappeared is a malfunction of the ignition coil (magneto). The figure below shows how the coil (magneto) looks from the gasoline trimmer for Patriot grass (Patriot).

To exclude the malfunction, it will be necessary to use a tester to check the Magneto trimmer for the grass, and specifically, its primary and secondary winding. On the primary winding, the resistance must be made from 0.4 to 2.0 Ohms. If the device indicates 0. this means that a short circuit was released in the winding, if infinity is an obvious sign of a chain break. The resistance on the secondary winding should be within the framework of 6 to 8 kOhm.

On some coils, it sometimes reaches the value of 15 kOhm.

If the passage, if your lawn mower is poorly starting in different ways after starting immediately stalls, pay attention to the air filter, since you will like it, under the influence of which the air does not enter the combustion chamber, and fuel ignition does not occur. To check if the filter is the case, remove it and try to start the engine. If he earned, the reason is found. The filter needs to be replaced or washed and dried perfectly before installation. For which the design is intended when you found oil in an air filter, it must be washed with gasoline, perfectly squeezed and dry for two or more than 2 hours before installing in the area.

In that case, when the air filter is removed, the unit does not start in any case, it is recommended to check the fuel filter.

This filter cleans the fuel of probable pollution. If it is scored, then gasoline does not enter the cylinder, and, accordingly, the unit does not work as it is also called stall after starting. The fuel filter is located at the end of the fuel hose, which is located in the fuel tank. To get to the filter, you need to extract a cork with tubes emerging from it.

When extracting traffic jams, a fence hose can disconnect and stay in a tank. It is extracted with a tweezer.

Next, remove the old fuel filter from the hose and put on it a new, in advance acquired. You can also clean the fuel filter if you do not have new. The filter must be fixed on the hose using a spring latch.

Install the fence tube on the cork and stick the last one in the tank.

It must be emphasized that in some models of trimmers, the fence hose is not on the traffic jam, but the snuffle of the tank. You can extract it with a tweezer in other words of the hook bent from the wire.

Sapun is a circular valve that is designed to level pressure in the gas tank. If it scores, it does not let air towards the tank, then a vacuum appears snitches for fuel, and the fuel ceases to enter the carburetor. To check the valve serviceability, remove the hose that comes from the tank to the carburetor. If gasoline from the tank does not follow, it means that the saopan is clogged.

Trimmeres users are often asking themselves: where is the sapun? This valve is usually in the gas tank cover and looks as shown in the next figure.

It is easy to clean the bacon painful: disassemble the valve and wash our clients remains to our client. In some gas troops, this valve can be placed directly on the fuel tank. It is impossible to find it immediately, since it is covered from the eyes under the starter case. It is cleaned with such a saapun using an ordinary needle.

The prerequisite that the trimmer for the grass significantly lost its power, and when trying to grow the engine speed, it gains them slowly, is often clogging of the exhaust channel through which exhaust gases emerge from the combustion chamber.

It is necessary to remove the muffler so that the bar does not get inside the cylinder. Next, clean the exhaust channel from a car.

This must be done very neatly, avoiding the inception of soot in the combustion chamber.

After this procedure, the weak power of the unit and a leisurely set of speed of rotation of the mowing head will not just not upset you.

Fuel overspending. Where does he come from in Motokos?

Probably, the users of the braids noticed that after a certain period after the start of the device, he begins to vibrate very much. On some trimmers, mainly in models more expensive, the anti.vibration system is installed in the appearance of shock absorbers, seized between the engine and bar. However, sometimes even she does not help from strong vibration. A prerequisite that a powerful vibration occurs in the trimmer, and perhaps a small amount is also called the complete absence of lubrication on the hard, as it is also called a flexible shaft, which is snot of the rod of the apparatus.

A change in the lubrication of a hard shaft occurs as follows:

  • unscrew the gearbox located at the bottom of the bar;
  • After removing the gearbox, the end of the shaft is visible, for which it is necessary to pull the part;
  • after extracting the shaft, it must be abundantly lubricated with a special lubricant “Shrus-4” or ordinary-“Litol-24”;
  • Apply a small amount of grease on the shaft and moderately spread it over the entire length of the part, including the slots at the ends of the table (if they worked, the shaft will have to be replaced);
  • After lubrication, stick the shaft back into the bar and put the gearbox in your former place.

Lubrication of the flexible shaft is carried out in this way:

  • unscrew and remove the mowing head;
  • remove the bar from the electric motor by unscrewing a couple of bolts;
  • remove a flexible cable from the bar;
  • Lubricate the cable with grease over the entire length.

This is done like this: at first you need to lubricate the end of the cable, and then stick it into the bar, after that, during the progress of it inside the pipe, you should apply a lubricant to the part and moderately distribute it over the surface. Then stick the bar with a flexible shaft into the electronic engine and fix it.

If the passage, when the lubricant did not help, and the vibration continues to appear, you will need to change the flexible shaft.

The trimmer for grass is overheated for many reasons:

  • Gasoline has not the same octane number indicated in the annotation to the aggregate;
  • The proportions of gasoline and oil are not observed at the time of the manufacture of fuel consistency;
  • 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 above the time due to the annotation;
  • A low.power trimmer for grass on a thick and hard grass is used, the device works with overload and heats up rapidly;
  • shifted towards the bar as it is also called the cassette cover.

The latter occurs if you install a mowing head inappropriate for this unit, in other words, when the axis moves inside the bar. These configurations make it difficult to rotate, the load on the engine increases, and its overheating occurs.

Repair of a trimmer for grass Husqvarna 333r

Husqvarna 333R grass faults for 3.5 seasons of active commercial operation (required replacement):

  • The gearbox of the Husqvarna grass is assembled: a piece of the aluminum case broke off after a strong blow about a piece of steel pipe sticking out of the ground (I, together with the gas station, deployed 180, and the Windsor 300-3 2 mm (1 ″ metal knife was bent “bowl”). What did: made a steel temporary clamp.
  • The aluminum engine of the engine. both the front ear of the mount broke off. Such a trimmer malfunction for grass.
  • One bolt of the muffler mount (the edges of the Husqvarna bolt head smoothed out).
  • It is advisable to change the muffler (they rivet and a little inside the “overgrown” by the haul). Or at least clean the sparkling grid if they were not removed at the beginning of the operation of a trimmer for grass.
  • The steering rack to the trimmer pipe for Husqvarna grass (one ear from two) broke off.
  • Weak thread for a candle in the cylinder head (try not to twist the candle unnecessarily).
  • The axial backlash of the crankshaft appeared.
  • Husqvarna lawn mowing Zama C1Q gaskets for the Zama C1Q carburetor.
  • Still regarding the repair of a trimmer for grass: in the second season (somewhere after 170 bedrooms of gasoline) it was necessary to add paper to two long screws of the Zama C1q carburetor (in the intake plastic collector, the carving was smoothed out) to eliminate the air leakage due to the weakened. screws.
  • Also, in the second season, the thread was disconnected-“impatient” from the cork of the tank (a ball of ball knot).
  • The rear screw of attaching the aluminum trailer for the grass for the grass Husqvarna replaced the larger one (thread smoothed in the plastic case).
  • A plastic loop broke, for which a trimmer for Husqvarna grass is suspended on a hook of a strap. Made a metal loop.
  • Replaced both side screws on the lid of the shock absorber of the trimmer for the Husqvarna 333R grass. the body was “sawn” in the aluminum cushion of the shock absorber (drilled both in the shock absorber and in the pipe).
  • Replaced the screwing of the wire on the ignition coil (the thread was smoothed in the aluminum case).

Note: I read somewhere that the production of two-stroke engines for refusal is no more than 500 hours, and I have burned in 3.5 seasons

370 liters of gasoline, t.e. if 0.35 l. per hour, already the operating time is more than 1000 hours! Husqvarna 333r grass trimmer. a very reliable trimmer for grass (lawn mower).

REPAIR OF THE LAW: How to Replace the Gearbox bearings

Trimmer malfunction for grass: tell me how the gearbox is analyzed on a trimmer to replace the bearing (Husqvarna). And whether he understands at all?

Answer: Husqvarna lawnies gearbox can be disassembled to change spare parts such as bearings, conical gear gear, housing (t.to. Reducer assembly for a trimmer for Husqvarna grass costs about 150.) It is necessary to remove it by sending the tightening bolts below, be sure to wash (for example, gasoline), then reduce the ends of the locking spacer ring (there are two of them on the gearbox) and pull out bearings with a small shooter of the bearing. They should easily go, since the upper bearing is no longer tightened by the case, and the drive shaft of the trimmer for the grass of Husqvarna comes out from the bottom.

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.

Possible causes of malfunctioning in electric braids

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

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

To exclude the problem with the voltage, it is required to check its size in the outlet with a multimeter or tester, from which power.cocked power is taken. If it is less than the minimum acceptable value, then to increase it will need to turn off all electrical appliances or install a stabilizer.

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

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

Brushes can be worn out, as a result, contact will disappear, which leads to stopping the electric motor. The brushes are easy to replace. Features of the process are determined by the Motokosa model used by the model. Along the way, you will also need to clean all contacting surfaces.

In the case of burning windings, if you continue to mow grass or shrub, the electric motor will quickly burn. This will be accompanied by the appearance of the smell of Gary, up to the melting of individual details. You need to replace the electric motor.

Braining rotating parts occurs for various reasons. To identify and eliminate them, you will need to sort out the drive knot. There are models in which the number of revolutions is automatically adjusted depending on the load, increasing when it increases. they idle speed drop.

The video shows an algorithm of actions to identify the most common reasons why a trimmer for grass does not gain the required speed:

The market presents a wide selection of trimmers from various manufacturers. They are characterized by general reasons why the moment. Also, each unit is equipped with operating instructions. In it, the corresponding section contains the necessary recommendations on this issue regarding the applied model.

If, in the process of independently eliminating problems, it was not possible to achieve a positive result, then it is better to seek help from specialists. It should also be involved in solving the problem of professionals in the absence of minimum experience and skills in such a case as not to harm. The most difficult node is the engine. Only experienced masters are permissible to work with him. When the lawn mower is under warranty service, the best option is to contact the service center where they will diagnose and repair technology.

What to do if the lawn mower stalls when you press the gas

Most often during the periods when the lawn mower stalls when the gas is added, the cause will be the air damper, more precisely, its condition: it clogged. Structurally, the part is located in the place where the resulting fuel is sprayed behind it, and, accordingly, the product collects all inclusions in low.quality gasoline. To eliminate the problem, you just need to clean it. The same situation can occur with a filter clogged, but it is eliminated similarly. Total, we specify the reasons for which the tool is led to the gas to the stalled state:

  • a clogged air damper;
  • The clogged filter is fuel, and when you give gas, this is especially noticeable;
  • the air of the crankshaft shaft occurs;
  • damaged gasket between the cylinder and the carb.

When you cleared, washed and blew elements, but again the lawn mower stall when you press the gas

  • Dosage carburetor.
  • The appearance of cracks on the fuel hose caused air leaks.
  • The occurrence of problems with the oil seals.

In the process, situations arise when the lawn mower at high speeds is subject to a similar sharp stop. It occurs for the following reasons:

  • due to problems with the circulation of the fuel mixture;
  • with air leaks;
  • The fuel intake hose is poorly connected or cracked and cannot be used;
  • stab or clogged the valve of the cover of the gasoline tank;
  • The carburetor was resolved.

Cutting the cutting nodes of the lawn mower

The saw settings are stupid over time or wear out. Working with the tool becomes intense, the load increases, the quality of the crook deteriorates. Metal saw canvases are pulled, plastic changes.

If a cutting tool for a trimmer serves as a cutting tool, it gradually wears out, and new material is installed in the reel. The principle of operation of the cutter with a fishing line is concluded in the gradual promotion of the coil under the influence of centrifugal force. When in contact with the grass, the fishing line for the trimmer is abrasion, from the coil is served gradually. A special winding is needed so that two cutting elements come out at the same time and do not get confused with each other.

The figure shows how to correct the fishing line for a trimmer to the reel of a lawn mower. Before winding a new fishing line for a trimmer is necessary:

  • Taking the nozzle, carefully remove the lid, holding the spring with your hand;
  • From the coil, remove scraps of the old fishing line;
  • measure 5 meters of a new string and fold it in half;
  • in the coil guides at 2 ends, hook the middle part for the recess and wind up in the direction of the shooter for each half of the string;
  • The remaining 20 cm draw through special recesses at the opposite ends of the coil;
  • Install a spring and washers, take the ends of the fishing line outside, close the drum with a lid.

DIY repair trimmer rod

Details: a trimmer bar for the grass with your own hands from a real master for Olenord.com.

Trimmer repair is needed when the device does not cut or it works incorrectly. All owners of personal houses and suburban areas are familiar with an unnecessary vegetation, which is sometimes difficult to get rid of. As clear, progress does not stand in one place and new developments and useful inventions arise in all areas. It hurts agriculture. You no longer need to mow the grass with old ill.wing devices, modern benzo.cosers came to the rescue, which are able to get rid of vegetation in the most inaccessible places.

A gasoline trimmer can be mowed grass even during cloudy weather. It is easy to care for a personal plot using this unit painfully, and to cope with this occupation will be able to at least some adult man.

Despite its multifunctionality, as it doesn’t matter what kind of technique, trimmers for grass tend to break and fail.

Not every person will be able to repair the lawn mower with your own hands, because for this we need the ability to repair electronic devices, but now we will try to figure out how to start a trimmer for grass without a starter and how in general you can debug his work with your own hands.

Do.it.yourself trimmer repairs of a do.it.yourself grass implies the elimination of all malfunctions, which interferes with the normal functioning of the unit. Among the most common, the following can be noted:

  • CPG breakdown (cylinder-piston group) of the engine;
  • The trimmer for the grass fails when trying to increase the speed of work;
  • ignition coil breakdown;
  • There is no connection between the engine and the gearbox;
  • There are extraneous sounds during work;
  • the engine cannot develop the desired speed.

The breakdown of the engine CPG can occur due to the low quality of the fuel or wear of the motor parts. As you know, the lubrication of the piston group is carried out due to the clock, which is added to gasoline. In the old oil, the lubricant falls in the form of a sediment, which makes the oil unsuitable. If you continue attempts to launch a trimmer for the grass, you can ruin the motor in a matter of seconds, and this will entail additional costs of repairing a trimmer for grass. This breakdown is considered the most expensive. To eliminate it, it is necessary to replace the piston group assembly, to be more precise, it may be necessary to replace the cylinder, rings, pistons and seals. In such cases, it is unlikely that you can do without additional help, unless you yourself are a master and know how to handle a similar technique.

The video considers the most common breakdown of the benzos and how to fight it works 100% verified

Please forgive me for the quality of the video. There was a problem with a video editor. But I hope. What will happen to you

Do.it.yourself lawnies can be repaired with your own hands if it starts and works at idle, but then it bursts when you try to increase the speed of work. To eliminate this breakdown, the carburetor repair or cleaning the muffler or gasophilter is required. At first glance, everything is quite simply solved, but if, after you clean the clogging details of the trimmer for the grass, it has not earned, then additional diagnosis may be required.

The main sign that the ignition coil failed and the repair of the trimmers is required is the lack of sparks on the candles. It is very important in this breakdown not to rush with the replacement of the coil, in most cases the cause of the breakdown is the absence of contacts, in the switch button, which may have broken down, or if the problem is in the candle itself. It is required to check it, perhaps somewhere breaks the current or there are gaps or soot.

If the trimmer engine for grass cannot develop the desired speed, it is likely that an air filter has closed or garbage in the engine itself is present. The solution to the problem is clear at once. to clean the engine and filter, in some cases it may be necessary to replace the filter.

In the process of work, most users of trimmers are faced with constant noise. If you hear a characteristic knock, as if on metal, it is likely that the engine in the trimmer has overheated or does not pass fuel. To eliminate this sound, you need to pour gasoline or turn off the mower for a short time.

Do not exhaust the unit: if it constantly works for wear, then its service life is dreamed of several times. If the knock is felt in the engine itself, then the reason lies in the malfunction of the piston, piston ring, in a worn cylinder or crankshaft bearing. In order for the knock to disappear, you need to replace the failed part in the trimmer.

Sometimes it happens that the engine in the trimmer works fine, but at the same time the output shaft rotates very weakly or does not rotate at all. This is displayed that when a trimmer for grass touches the grass, it completely stops working and turns off.

To resume the normal operation of the mower, it is required to check the 3 main components, namely:

The gearbox is a very important component, therefore, the repair of the trimmer for grass in this case should be carried out by an experienced master, and so that in the future there is no such breakdowns, the gearbox needs to be provided with appropriate maintenance.

In addition to the above breakdowns, other malfunctions occur, for example, the power button is sunk or the limiter disappears from the mowing head. You can replace the power button using a soldering iron, and the limiter can be wrapped with copper wire. You noticed that the fishing line for the trimmer was torn or ended? It is enough to buy a new skein of the same fishing line diameter and, having dismantled the drum, wind it on a bobbin.
