TRAMMER Repair (Benzosos, Electros)

Our Servy service center repairs various trimmers with gasoline, electric, batteries of a large number of manufacturers. For gardeners, lawmakers and trimmers for grass are a necessary, useful and not replaced assistant in the struggle for a well-groomed summer cottage and adjacent territories in the spring-summer period. And it’s not for nothing, the trimmer for the grass comes from the English word, which means “put in order” or “trim”. And the first trimmer for the grass was invented by a businessman from Texas. George Bollas in 1972, in order to trim the grass and not damage trees, go around flower beds and paths. The design of the trimmers (benzos) is a working cutting tool of which is located at the end of the bar, equipped with an electric or gasoline engine that resembles an ordinary braid, which, in fact, came trimmers for grass.

The main malfunctions of gasoline trimmers

The most frequent are the breakdowns of the benzos associated with the following structural elements:

  • engine (in particular with a piston system);
  • carburetor;
  • bar;
  • starter (cliff of rope, breakdown or exit from the gearing of the spring);
  • with the ignition system or fuel supply;
  • transmission mechanism (gear);
  • filters and muffler.
  • the appearance during work of motorcycles of uncharacteristic sounds;
  • The lawn mower does not turn on, does not gain the required revolutions or stalls;
  • When operating the engine, the working part does not rotate or slip;
  • leakage of gasoline;
  • excessive heating of individual nodes.

Small breakdowns can also occur, which are found without any special diagnosis:

It is easy to fix minor malfunctions. Repair of a gasoline trimmer for grass in more complex cases will require preliminary diagnostics to clarify the exact reasons. If there are appropriate knowledge and skills of locksmith work, then problems can be eliminated independently, replacing the failed parts.

Dismantling of gasoline braids for grass, lubrication of its parts and replacing faulty elements

To disassemble the lawn mower to carry out repair work, in general, the following devices will be needed:

  • set of screwdrivers (with different tips) and wretched keys;
  • a small puller for removing bearings;
  • special candle key;
  • a hammer.

In each case, you need to disassemble individual nodes.

It should be borne in mind that the starter (start.up) in a number of models is non.devastated. in this case, with problems with it, only replacing the element is possible. If the node is disassembled, then it can be repaired by removing and replacing the rope and the spring, or by installing the latter in place (when it exit from the gearing).

Analysis and replacement of the bar

Quite often it is required to repair a trimmer bar for grass. It is a design from such parts:

  • a drive shaft of steel, which has multifaceted or square slots on the upper and lower ends;
  • aluminum tubes;
  • plastic sleeve designed to maintain a centralized position of the drive shaft in the tube (so that there is no vibrations);
  • shock absorber made of rubber required for connecting the bar with the motor;
  • steering wheel with a handle used to control, and a stand, belt.

In some models, the shock absorber is between the steering rack and the bar. All control elements (lock lever, ignition switch, gas button) are located on the handle.

A conical angular gearbox is connected to the lower end of the bar, but some light models are available without it. This is due to the fact that their bar has a curved shape, and the shaft is a flexible cable.

How to disassemble the bar and then collect it to lubricate the shaft or its replacement, in detail is placed in the video further. In the same way they change the broken bar for a new.

Often it happens that the multifaceted or square slots of the drive shaft “lick”, while the working mechanism does not rotate or does it with a feather. Then the shaft is changed.

When a knock appears in the tube, you should disassemble the bar and check the condition of the sleeve, and if necessary, replace it. How to properly assemble a gas handle on a trimmer, is considered in the video below.

If there is no rod, suitable for installation, then you can pull the broken place with a clamp or apply the likeness of the tire. Such a measure is temporary, so you should make a replacement as soon as possible.

Clutch repair

When a knife or fishing line for a trimmer when operating the engine at idle is almost constantly spinning, and uncharacteristic sounds come from the front of the motor, this indicates a clutch clutch breakdown. The reason is a bursting spring. At the same time, the technique mows normally.

If there is a slip, then in addition, the pads have worn out.

The traffic trimmer is repaired as follows:

  • Remove the lid from the silencer;
  • remove a metal stand;
  • After remove the lids of the cylinder and the starter to gain access to clutch;
  • unscrew the side screws to remove the shock absorber lid;
  • They take out the tube from it, having previously let the tightening bolts;
  • unwind the clutch (presented in the photo further);
  • examine the condition of the spring, pads and bearings;
  • They cling to a new spring, passing the hooks into the corresponding holes;
  • To replace the pads, you need to remove the spring, and then unscrew the bolts on them.

If necessary, stop the crankshaft using, for example, ropes.

Repair of a gasoline engine, carburetor and gearbox

Malfunctions with the engine can be caused by problems with the piston system, seals, rings. To eliminate them, it is necessary to remove the drive motor.

To determine what exactly caused the breakdown is not easy. In the presence of a guarantee, the mechanism should be attributed to the service center for diagnosis and repair. If you turn to specialists for help, it should be borne in mind that the most commonly required to replace the piston rings. To do this, you need to disassemble the engine, get the piston. Do this in the following sequence:

  • Remove the lid of the plastic case, unscrewing the screws or pressing the clamps;
  • disconnect the bar with the crankshaft;
  • Remove the cylinder head;
  • take out the piston and rings;
  • if necessary, they are replaced;
  • carry out the assembly in the reverse order.

The rings should be installed carefully, because they are quite fragile.

How the piston is placed and the seals are replaced during the repair of the engine, it is clearly shown in the videos further:

With regular use of the lawn mower, a gearbox may break. Histers, bearings wear out in it (they can also break). For this to happen infrequently, this node should be regularly lubricated. The frequency is almost always indicated in the operational instructions for the model used (at least once per season). A video below can serve as a repair instructions.

To grease the gearbox, unscrew the cork and simply squeeze out a suitable lubricant inside the node, scrolling off the shaft.

Your own carburetor can only be removed and cleaned, and also replace the gasket between it and the engine. The tightness of the node at home is determined quite problematic. The main thing is to properly assemble equipment after repair, so that the trimmer for the grass works without problems.

Replacing a piston trimmer for gasoline grass

Trimmer repair is necessary when the device does not turn on or operates incorrectly. All owners of private houses and suburban areas are familiar with the problem of excessive vegetation, which is sometimes difficult to get rid of.

As you know, progress does not stand in one place and new developments and useful inventions appear in all areas. This was also affected by agriculture.

You no longer need to mow the grass with old uncomfortable devices, modern benzo.cosers came to the rescue, which can get rid of vegetation in the most inaccessible places.

A gasoline trimmer can be mowing grass even during cloudy weather. It is very simple to care for the personal plot with this unit, and any adult man can cope with this occupation.

Despite its multifunctionality, like any technique, trimmers for grass have the property of breaking and failing.

Not every person can do the repair of the lawn mower with your own hands, because for this it is necessary to repair electrical devices, but today we will try to figure out how to start a trimmer for grass without a starter and how to debug it with your own hands in general.

Breakdown of a trimmer for grass and methods for their elimination trimmer repairs of a 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.

replacing, seals, diold, installation

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.

I apologize, but I made a reservation. When lengthening the rings, if they are installed towards the exhaust, they will be intens.

How to change piston on a trimmer.

In this video I will show how to quickly change the piston on the trimmer. I will change on the trimmer. 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.

Replacing the ignition coil

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.

Other common breakdowns

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.

If you want your mower to work for a long time and without interruptions, then it needs to be provided constantly, you can contact the service centers or make diagnostics yourself.

DIY lawnies repair: main malfunctions and their elimination

The lawn mower is one of the main instruments of the summer resident used to quickly bring the land in order. The owners of private houses acquire this weapon for mowing grass in the personal territory. The period of active use of benzos and electric trimmers falls on the summer period.

Before starting operation, the tool is brought into working condition: the rubbing parts are lubricated, the cutting headset changes, the fuel mixture is poured into the tank. If the engine does not start or stalls quickly, without gaining enough revolutions, then you have to look for the causes of problems and eliminate the identified malfunctions.

To carry out the repair of the lawn mower with your own hands, you need to understand its device and the principle of operation of the main nodes. This information can be found in the operating instructions, which the manufacturer applies to garden equipment without fail. Check for such a manual when buying a chainsaw.

The import tool should be accompanied by instructions written in Russian.

How the household lawn mower arranges?

A long tubular bar is attached to the gearbox of a two.stroke internal combustion engine. Inside the rod passes a shaft transmitting torque from the gasoline engine to the cutting mechanism.

Fishing line for a trimmer or knives rotate with a frequency of 10,000 to 13,000 revolutions per minute. In the protective case of the gearbox, the presence of holes is provided, into which a lubricant is introduced using a syringe.

For the convenience of using the tool, the manufacturer equips it with a special adjustable belt thrown over the shoulder.

The cutting headset is attached to the gas codes:

  • Lines for a trimmer, the thickness of which varies from 1.6 to 3 mm, is located in a trimmer head. During the mowing of the grass, the fishing line for the trimmer is worn out. The fishing line is replaced quickly and easily in two ways: by winding the fishing line of the same diameter on the bobbin or by installing a new coil with an already wound fishing line.
  • Steel knives with bilateral sharpening a lawn mower to cleanse the site from weeds, small shrubs, hard herbs. Knives differ in shape, as well as the number of cutting surfaces.

On the U-shaped, D-shaped or T-shaped handle attached to the bar, there are tanosa control levers. The cutting mechanism is fenced with a special casing.

Domestic motorcycles are refueling with a mixture prepared from gasoline and oil, which is poured into the fuel tank. The device of semi.professional and household motorcycles equipped with a four.time gasoline engine is slightly different.

The gas station is also different: the oil is poured into the crankcase, and gasoline is in the tank.

A measured piece of fishing line is folded so that one end is longer than the second by 15 cm. We put the loop into the slot on the coil, and begin to wind up in the direction indicated by the arrow

What to do if the engine does not start?

If the lawn mower fails is not possible, then the first thing is to check the presence of fuel in the tank and its quality. For refueling the tool, it is recommended to use high-quality gasoline purchased at gas stations, the brand of which should not be lower than the AI-92.

Savings on cheap fuel can lead to a breakdown of the cylinder-piston group, for the repair of which a third of the cost of Motokosa itself can take. It is equally important and correctly preparing a fuel mixture of gasoline and oil. The proportional ratio of these components of the mixture is indicated by the manufacturer in the manual.

Do not prepare the fuel mixture in large volumes, since during long storage its properties are lost. It is better to use a freshly prepared mixture.

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

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

The air filter also needs to be in the test. During contamination, the part is removed, in the field is washed in gasoline and put in place. In the country or at home, the filter can be washed in water using detergents.

After that, the filter rinses, squeezes and dries. The dried filter is moistened with a small amount of oil used to prepare the fuel mixture. Excess oils are removed by compressing the filter with hands. Then the part is installed in place.

replacing, seals, diold, installation

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.

Tips for quickly launching the unit

  • 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.

Repair of the bar motorcosa. Primary diagnosis of a trimmer for grass.

The proper operation of the engine and the lawn mower in general is affected by a huge number of factors that are usually interconnected. If you fail to determine the malfunction, contact the proven service center.

I would like to note that before proceeding with disassembly and serious repair, you should check elementary consumables. These “little things” often affect work and, perhaps, repair of a trimmer for grass will cost “small blood”, so to speak.

Spend of the ignition-lack of soot, electrode clearance (0.5-0.6mm-or according to the instructions), good spark

Fuel filter. lack of pollution, mechanical damage, good throughput. Periodic replacement according to the maintenance schedule in the operating instructions

Air filter. lack of sawdust and pollution. Periodic cleaning in soapy solution and purge under high pressure. Replacement of the air element according to the instructions for the expulsion

Let’s get acquainted with other possible malfunctions:

It is worth noting that many owners confuse air leaks with a malfunction of the carburetor. Symptoms for air dsos into the engine are a strong oversuance of revolutions, both short and constant. Or a braid for grass simply refuses to start.

The main causes of air leaks on the Chinese trimmer:

  • Passes the crankshaft oil seal (12227mm small). from the side of the starter
  • passes the crankshaft oil seal (15307mm large). from the side of the flywheel
  • wear of the gaskets of the carburetor
  • Carburetor adapter

Actually, it is possible to understand what exactly from this list caused an air leak on a gasoline mower can only be examined by a detailed examination. Unscrew, shoot and be tormented in any case, so further in order.

Replacing the seals of the Chinese trimmer for grass.

One of the main causes of air leaks into the engine are crankshaft oil seals. In general, this problem is the most common on Chinese trimmers, and in some cases, seals begin to pass the air in the first year of service. All the fault of low.quality rubber products of such mowers, well, no one has canceled natural wear.

Essle for different sizes were installed on both sides of the crankshaft (12227mm small and 15307mm large). You can safely sin on the seals if it begins to “snot”. Another indicator of their malfunction is floating turnover when working for “hot”. Next, we will consider in detail the process of replacing.

Replacing the omentum of the Chinese trimmer for grass from the side of the starter:

We unscrew the spark plug, block the movement of the piston with a stopper. Remove the starter (p.31). 13mm with a head of 13mm we unscrew the starter ratchet (p.35). Traces of a gas mixture on the omentum indicate its necessary replacement. With a thin flat screwdriver (awl, or any similar object that is at hand) we remove the old oil seal (p.36), pry it with a screwdriver from the side of the crankshaft and remove it.

We apply a small amount of oil on the inner surface of the new omentum before installation (you can use oil, which is used to prepare a gas station)

We blow out and degrease the seat under the oil seal, evenly install a new oil seal.

Replacing the oil seal of a gasoline trimmer for grass from the side of the flywheel:

We unscrew the spark plug, block the movement of the piston with a stopper.

For convenience, remove the crankcase cover (p.58) unscrewing 4 screws (p.61)

Unscrew 2 clutch mounting screws (p.57) with washers (p.56), remove the clutch assembly and the washers under it (p.53)

Unscrew the nut (p.52) flywheel (p.51), but not to the end. Not a strong blow to the nut “knock him off the crankshaft”. Unscrew the nut, remove the flywheel and the veneer. We will examine the surface of the oil seal. traces of moisture, or wet pollution, scuffs and other damage on it are a signal to its replacement.

With a thin flat screwdriver (awl, or any similar object that is at hand) we remove the old oil seal (p.50), pry it with a screwdriver from the side of the crankshaft and remove it.

We apply a small amount of oil on the inner surface of the new omentum before installation (you can use oil, which is used to prepare a gas station).

Replacing gaskets and a carburetor adapter on a Chinese trimmer:

Another reason for the air leaks can be a carburetor adapter.

Device motorcycles. Gasoline trimmer device for grass

Numerous models of manual motorcycles that are available on the market today differ in power (and, as a result, in their capabilities), weight, the presence of certain additional functions that increase the ease of use, but the fundamental scheme of the instrument device remains unchanged.

As a power drive in any gasoline trimmer, an internal combustion engine is used. By means of a hard or flexible shaft, rotation from it is transmitted to a cutting element. a coil with a cord (fishing line) or a special knife. The shaft is placed inside the metal rod, on one end of which the engine and the fuel tank are fixed, on the other there is a cutting head.

replacing, seals, diold, installation

In the middle part of the rod, the handle is attached. Most often, it is precisely on it that keys, buttons and switches are placed, with which the work of the trimmer for grass is controlled.

The layout of the control elements can differ slightly depending on the model of the tool, but, as a rule, this includes a button for jamming the engine, the gas key, which allows you to control the throttle darling of the carburetor, and the stopper of this key in the pressed state, facilitating control with large volume of work.

Determination of the causes of the malfunction

If the trimmer engine for grass does not start or stalls immediately after starting, when overheating or during the functioning of the device, extraneous noises are heard and vibration is clearly felt, it is important to perform a visual inspection and identify a non.working node.

  • the presence of fuel in the tank and lubrication in the main nodes;
  • serviceability of the spark plug and its performance;
  • the purity of the fuel and air filter motorcycles;
  • Clutching the exhaust channel and the device’s cabin;
  • The quality of the used fuel and lubricants.

To determine the functional performance of the ignition of the lawn mower, you should determine whether the candle works by testing the appearance of a spark in contact with the body of the functional device.

The spark plug itself can be changed to a new one, after driving the candle canal, if necessary, the old element is also dried, cleaned with special devices and returned to place.

Repair of the carburetor

If necessary, it is possible to disassemble and thoroughly clean the node with your own hand, using gasoline, cleaning the nozzle and channels is used by compressed air.

Gear lubrication of a trimmer for grass

Lubrication of gears must be carried out regularly in accordance with the recommendations set forth in the operational instructions of the model used. You need to do this also if:

In addition to the gearbox, it is also necessary to regularly lubricate the shaft of a trimmer for grass. This is the norm of proper care of the device.

With the constant use of a trimmer for grass, its gear mechanism experiences a load from grass, dirt sticking on knives, or due to a change in torque. Lubricants must be selected high.quality to extend the service life of the gearbox.

Used types of lubrication

When choosing lubrication, it is necessary to take into account the following factors:

Famous manufacturers, for example, STIHL, Husqvarna and others, in addition to trimmers, produce lubrication for them. Such products not only reduces wear, but also protects the metal of gears from corrosion. Therefore, for motorcycle from these brands, it is better to use their lubricants.

If the composition used for lubrication has good adhesion, then it is practically not squeezed out of the gearbox through the gaps.

For different models, lubrication is consumed in different ways. This is determined largely by the intensity of the use of motorcycles and heating the transmission mechanism. It is believed that the lubricant is enough if the temperature of the gearbox during operation does not exceed 40 ° C.

By consistency, lubricants for a trimmer for grass can be:

In terms of composition, the following types of lubricants are in demand:

  • graphite, significantly reducing friction, as a result of which the rotation of the gear improves;
  • lithium, which are also an excellent anti.corrosion composition, saturated with increasing the wear resistance of metal with additives without harmful substances;
  • universal, containing mineral oils and improving operational characteristics components.

An example of suitable lubricants are: Champion EP-0, Gear Grease Oregon, Oleo-Mas, Azmol 158, Litol.24. You should also pay attention to the advice of manufacturers on this issue and use the materials they offer. You can buy them at specialized retail outlets.

The algorithm for self.lubrication of the gearbox

To make lubrication of the gear ratio, its preliminary disassembly is not needed. A special hole for these purposes has already been laid in the device (it is shown in the photo below). In addition to gears, when lubrication, you need to pay attention to such elements of the mechanism:

Pour oil or apply solid grease through a tavniper closed by a screw. At the same time, they perform actions in the following sequence:

  • The gearbox body is cleaned of dirt and adhering grass, especially thoroughly the plot around the plug so that the garbage does not get inside the mechanism;
  • Using the appropriate tool (often it comes with a trimmer), the cork is unscrewed;
  • The selected lubricant is introduced from the tube into the open technological hole, or using the syringe, as shown in the photo further;
  • screw the cork in place.

When making lubrication, you need to rotate the knife so that it is evenly distributed through the teeth of moving gears.

If for any reason the gearbox needs to be disassembled, then the old lubricant must be completely removed from the entire surface of the gears and housing, shaft, and only then use the new. The disassembled mechanism is conveniently lubricated with solid compositions.

The entire reducer lubrication process is demonstrated in the video:

Lubricating the gear node is required at least once during the year, but it is recommended to do this every 20 hours of intensive use of motorcycles. If the first signs of malfunctions with the mechanism appear, then you need to make lubricants as quickly as possible.

How to replace a trimmer gearbox for grass: an algorithm of action

To replace the gearbox with a similar part from the same manufacturer, it must first be disassembled and removed from the bar. At the same time, they act according to the following algorithm:

  • weaken the fitting bolts located under the transfer mechanism;
  • Using round.drawers, remove two corkscrew rings;
  • Applying the puller, pull the bearings from the driven and the leading shafts;
  • Then collect the mechanism, in the reverse order by installing all spare parts.

The disassembled transmission mechanism is shown in the photo below.

If the puller is not at hand, then you can try to gently knock down the bearings. When they have stuck and do not move at all, you can heat them using an industrial hair dryer (at a temperature of 600 ° C) and remove.

Collecting a gear node is easier than disassemble it. Only a light tapping with a hammer for planting parts in place may be needed. After assembly, it is imperative to check that the driven shaft turns out by hand.

Когда есть необходимость замены передаточного узла неоригинальной деталью, тогда следует учитывать их взаимозаменяемость. At the same time, it should be taken into account:

  • the diameter of the bar (this parameter often is 25.4 or 26 mm);
  • The parameters of the drive shaft. the shape of the docking space and the diameter (its common value is 8 mm);
  • option of consolidation of protection.

If the considered parameters coincide, then it will be possible to set a part from other models.

Timely lubrication of the gearbox will ensure its prolonged operation without repairs. In addition, modern materials protect the metal from corrosion well, increase its wear resistance. When choosing, preference should be given a lubricant recommended by the manufacturer of the operated trimmer for grass. If such compositions are not possible to purchase, then the analogs considered or other suitable in properties should be applied. When it is necessary to disassemble the mechanism during the repair, this should be done carefully so as not to damage individual parts.
