Repair and lubrication of a trimmer gearbox for grass
With frequent, intensive use of motorcycles, the gearbox can start to heat up or make sounds uncharacteristic for its normal operation, for example, rattle. This indicates that the mechanism must be lubricated. If this is not done on time, then more serious problems will arise (for example, gears will be quickly worn out and you will need to replace them), up to jamming. Other breakdowns also arise with the transmission mechanism. Reducer repair and lubrication can be performed independently. for this you just need to familiarize yourself with the features of these work and stock up on some available tools.
The gearbox of a trimmer for grass is a node that transfers the rotational movement of the engine shaft to the knife or fishing line. It is located on the lower end of the motorcycle rod. The gear node is also designed to lower the engine speed of the trimmer for grass.
The mechanism consists depending on the model of the motokos of several gears rotating at a high speed. As a result of this, they heat up due to severe friction. If the lubricant is not enough, or it is not at all, then the process leads to a strong overheating and failure of the parts, and, accordingly, the need to carry out a difficult repair. So that this does not happen, lubricate the gear node in time. Misused gearbox is presented in the photo below.
The reducers of modern trimmers of different models from various manufacturers differ from each other by the design and the size of the seat. It happens:
The most common diameters of round seats are 24, 25.5 and 26 mm.
Motokos is equipped with gearboxes with different types of gears:
Drive shaft and gearbox are very loaded nodes of a trimmer for grass, which are largely susceptible to wear. Between them, the movement is transmitted due to the adhesion of the teeth of the gears located at different angles to each other. Effective gear works only if there are no mechanical damage. In this case, the mechanism should not overheat, otherwise its jamming may occur.
The main malfunctions of the gearbox and ways to eliminate them
With a gearbox of an electric or gasoline trimmer for grass, various breakdowns occur. The most frequent of them are presented in the table further. There you can also find the reasons for their occurrence and methods of elimination.
|Reducer malfunction||Possible causes of breakdown||The method of elimination|
|The gear node is heavily warmed up||the use of unsuitable (low.quality) lubrication or its absence||you need to replace or add lubricants|
|The gears are new and did not get sick||It should be worked for a short time for a time without strong loads with regular stops so that the mechanism manages to cool|
|shaking of the shaft during rotation, the appearance of backlash and knocking||destruction or significant wear of any of the bearings||replace the failed bearing with a new|
|The transmission mechanism flies from the rod of motorcycles or stagger||Damage to its body||It is necessary to replace the part|
|In some cases, with minor damage, a clamp made of metal, a place with a fault is carried out|
|not fixed on the pipe||wear of the docking area||you can make a winding from the insulating tape at the mounting site or change the bar|
|The output shaft with a knife does not rotate or stops in case of an increase in the load||wear of the teeth on the gears or one of them||It is required to replace the interacting pair of worn details|
Bearings are destroyed due to the use of inappropriate lubrication or due to its absence. Their damage is also caused by severe operating conditions of motorcycles and the ingress of extraneous particles of the material (for example, broken metal teeth of mechanical transmissions) due to the fact that the integrity of the anthers is violated.
To remove the bearing, you need to disassemble the gearbox and use a special puller. If it is not, then you can try to do it with a hammer with a mentor. In this case, work should be carefully so as not to damage the seat. Using the pre.heating method to shoot the bearing is not recommended. This is due to the fact that the metal may lose the required operational characteristics.
If the knife ceases to rotate under load or stands still, then this is accompanied by an uncharacteristic sound.
Most gearboxes can easily be eliminated with your own hands. Replaced details are recommended to purchase “relatives” designed for the used motorcosa.

Why is a trimmer not starting for grass gasoline? Reasons and their elimination
Recently, a gasoline trimmer for grass has acquired the status of one of the main tools in the arsenal of summer residents. And this is not surprising, because a motorized braid for grass allows you to quickly put a personal plot in order. However, sometimes it happens that the trimmer for the grass does not start hot and even on cold. In such situations, you have to independently establish the cause of the malfunction. Let’s find out what to do if a trimmer does not start for grass. The reasons that most often lead to such troubles will be considered further.
Where to start the diagnosis of malfunctions if a trimmer is not started for grass? In situations where the tool stalls immediately after starting, it is worth examining the following units:
It is the breakdown of the above locations that most often leads to the fact that a trimmer for grass is poorly started. Let’s look at how to eliminate such troubles.
Suppose you don’t start a trimmer for grass. Breakdown of a trimmer for grass and methods for their elimination. 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. In this case, the first thing is to check whether the fuel is enough in the tank, as well as evaluate the quality of the fuel mixture. To refuel a motorized unit, it is necessary exclusively high.quality gasoline. It is recommended to use fuel, the brand of which is not lower than AI-95. Refueling a trimmer for grass with fuel of unknown origin, not bought at a gas station, is fraught with frequent failures in the work of the tool. This can cause a breakdown of the cylinder-piston system. Repair in this case often exceeds the cost of the device itself.
Why is a trimmer not starting for grass gasoline? Incorrect preparation of the fuel mixture may also lead to this, which consists of oil and gasoline. The proportions in which the specified components are connected are indicated by manufacturers in the guide for the operation of a trimmer for grass. Preparing the fuel mixture is extremely not recommended in large volumes, that is, for the future. Indeed, with prolonged savings, there is a loss of the determining properties of the substance. Therefore, if a trimmer for grass does not start, it is worth draining the old fuel and use freshly prepared fuel mixture.
What to do if the used fuel mixture is in perfect order, but a trimmer for grass is still not started by gasoline? The reasons for the refusal of the mechanism may lie in excessive moisture of the candle channel. To diagnose and eliminate the problem, it is necessary to do the following:
- To twist the candle. Wipe it thoroughly, and then dry it.
- Drain excess fuel in the chamber through the corresponding candle hole.
- Clear the old candle if there is a dozen on its surface. Rating of the best models of gasoline trimmer for grass: reviews, which one to choose better. Many owners of suburban and summer cottages are asked what is better to choose a gasoline trimmer for grass for grass. Cope with the task will allow the use of a conventional ladies’ nail file or file.
- When installing the element in place, set a gap of 1 mm. To check the parameter, it is enough to place any coin in the lumen.
- Collect a functional block back.
- Try to start a trimmer for grass.
It is recommended to perform a candle channel to dry for at least half an hour. However, in no case should you resort to the calcination of its elements. After all, heating the spark plug can lead to its final corruption. Что предпринять, если обслуживание функционального блока было выполнено в соответствии вышеуказанным рекомендациям, но триммер для травы не заводится, искра есть при этом? In this case, it should be treated with gasoline threaded connection. The latter does not need to be saturated abundantly fuel. It should only be slightly moisturized. Benzotrimmer. malfunctions and their elimination. Resort to such actions should be to ensure the ignition. After all, no matter how much the candle gives a strong spark, in an absolutely dry chamber there simply will not be something to ignite.

The video presents one of the common breakdowns of Chinese benzosos is associated with poor.quality assembly.
If even in this case a trimmer for grass does not start, it is worth evaluating the quality of the contact between the high.voltage wire and the candle. In the absence of a spark (in the presence of a reliable connection between the indicated elements), most likely, the problem is caused by breakdown of the ignition unit. In this situation, you will have to turn to the services of masters who will reinstall the knot.
Another common cause, due to which a trimmer for grass does not start, is the presence of a blockage in the filter area. To confirm the conjecture, just dismantle the indicated block and try to start the unit without it. If the engine of the trimmer for the grass has launched, most likely you will have to replace the air filter or at least perform a thorough purge of the old. In the presence of abundant contaminants on the surface of the filter element, it is necessary to use a new grid. Relying to such actions, you should not leave a suction pipe at all without a filter. After all, rush in this case can lead to the need to repair the entire piston group of the unit engine.

The main malfunctions of the starter of the trimmer for grass
It is not difficult to determine the cause of the breakdown of the starting device. There are several main options:
These details are shown in the photo below.
It may happen that the starting mechanism will be accidentally broken. The consequences will turn out to be deplorable if the ragged rope is wound around the flywheel of a working internal combustion engine: then the spring bursts, the pulley will tear off. But such cases when a complete replacement of the starting node is required, they rarely occur. In most cases, to fix the mechanism, it is enough to put a new spring or replace the cord.
Removing and disassembling the starter, replacing broken parts
To repair the starter of the trimmer for the grass, you will need to disassemble it first, and then collect it. This process is not a particularly difficult occupation. For work, you will need a screwdriver with the tip of the desired shape.
Everything should be done carefully, observing safety precautions, mainly that the spring does not injure the master if an accident.
Parsing the starting node
They disassemble the launch mechanism in order to install new parts instead of broken in the following sequence:
- spin a screw with a screwdriver, fixing the pulley with a starter lid;
- take out a spring and antennae;
- Remove carefully with the pulley (you need to unscrew the head or work, having dressed the glasses and gloves before);
- determine why the launch mechanism has broken;
- If the spring collapses almost completely, then it is replaced;
- When the spring exits from the hook, it is installed in the original place, bending the antennae before this (the photographs show the laying process);
To change the spring, you should work carefully and accurately: it can, under the influence of the effort caused by the installation of it in place, accidentally burst. Even if you carefully remove the video, then the spring strip flies very quickly from the coil and can injure your hand with its sharp edges.
Immediately putting a springy plate in the same place does not always work. It often slips, so attempts are required to repeat until the desired result is achieved.
The assembly of the starting node is carried out in a number of stages:
When making the stated manipulations, it is necessary to lay two goals. If this is not done, then the spring over time damage the plastic cup, and when it is pulled. Because of this, a feeling appears, as if the spring had flown. To eliminate such a drawback, you need to install this part of a larger length or an additional goal.
When such spare parts are absent, you can just unscrew the screw a little, and the starter knot will begin to work without shaken. But this option is temporary. it is better to repair qualitatively as quickly as possible.
After installing the spring, it should be pulled. The following actions are performed for this:
- Remove the handle from the starter cord;
- Then the rope is inserted into the coil groove;
- They stretch the spring, rotating the coil in the direction opposite to the clock of the clock arrow (reviews);
- make the desired number of revolutions specified in the instructions for the use of the trimmer model used and the corresponding length of the cord used;
- At the very end, the rope is threaded into a hole designed for this, located in the starter cover;
- put the handle in place, fixing it with a node.
If after the repair the spring continues to fly, then you can get rid of this in the following ways:
- Squeeze the suitable piece of the plate into the groove at the location of the spring hook;
- drill holes on two sides of the groove in the coil, into which the spring hook is inserted and fix it using a wire.
Replacing a torn cord
A torn rope is replaced in the following sequence:
- The old cord is removed;
- choose a suitable rope (thickness and length);
- Having reached it through a special hole in the coil, a knot is tied;
- Sprinkle a spring, producing the required number of revolutions;
- Fix the pen.
It is better to stretch the spring plate along with the partner so that the edge of the cord does not hit the starter mechanism.
It is easy to assemble a starter on a trimmer and wound a spring, only you should do it carefully and with caution. For different models, the gas tanks of the launching mechanisms are the same, so they are repaired in a similar way. In this case, there are some nuances associated with their constructive features.
How to independently disassemble and repair an electric braid
Before disassemble and repair an electric braid, you should check the condition of the outlet and the voltage in the network. If its value deviates from the norms specified in the instruction manual, then you should not even try to work as a device without a stabilizer designed for appropriate power. Otherwise, the electric motor may fail. Only after determining the fact that the cause of the trimmer refusal is directly connected with it, we can begin to analyze the mechanism with the repair goal.
Dismantling and repair of the electric part
Dismantling of electric cosmos for the repair of its electric part is carried out in such a sequence.
- Put a trimmer for grass on a flat surface (for example, a table) that does not contain extra objects.
- Spin the screws of the lids located on one side.
- Remove the unscrewed half of the case, getting access to the start button, electric motor, brush unit, bearings, electrical connections (these elements are shown in the photo below).
Brush and bearing nodes are presented in the photo below.
The braid for the grass will work without a thermorele, you will only need to constantly check the temperature of the electric motor, periodically let it cool down. You can also install a new similar sensor.
The button for starting the electric motor can be checked by the jumper by the jumper of its contacts. If the trimmer for the grass works, then the problem is clear. But this option is unsafe. Everything should be done carefully so as not to get an electric shock. To change the button, you should use the screwdriver to extract it from the seat and attach the wiring from the old to the new. After replacement, you need to assemble an electric shout, and then check its performance.
Replacing brushes is required if they are destroyed. At the same time, it is enough to pull out the old ones from the grooves, and set the new ones in their place.
The connecting terminals on different models of trimmers are practically identical, so the connection-reference of the wires is equally performed.
Replacing the bearing is a rather complicated operation, because it can boast and not be removed from the engine shaft. Tighten or hit it carefully so as not to damage the rotor or seat.
When a trimmer electric motor for the grass fails, and it must be replaced with a new one, you should carefully remove the fan and bearings, and then install them in the same place. In terms of expenses, replacement is almost comparable to the acquisition of a new mechanism. Its implementation in the absence of experience with electric motors is best entrusted to specialists.
Instructions for assembling the electric part of the motorcycles are as follows:
- install the engine, tightening the fasteners;
- connect an electric circuit;
- The wires are placed neatly between the individual compartments into existing recesses;
- close the top cover, snapping the locks and screwing it with screws.
After assembly, check the performance of the device.
There are a lot of possible breakdowns in gasoline and electric trimmers. So that the device is working for a long time, it should be kept clean, in a dry place. An important point is regular preventive measures (for example, reducer lubrication) and compliance with operation rules set forth in the instructions for the device. Buying equipment is better than high quality from well.known manufacturers.
Disassembled the mechanism, it is recommended to take pictures of the process in stages so as not to forget anything, and when assembling, not to miss a single part. When replacing parts, you should pay attention to the choice of suitable components: it is better to use original spare parts.
In some models, the rod consists of two parts. a coupling is used to connect them. Such devices are convenient during transportation.
Malfunctions and their elimination
Electric and gasoline trimmers have typical breakdowns and malfunctions. For devices running from an internal combustion engine, this is:
- problems in the carburetor;
- engine breakdown;
- problems with the fuel system;
- breakdown of the gearbox, starter, muffler;
- Air filter breakdown;
- Problems with ignition coil.
Electric units have specific breakdowns:
With simple problems, you can make a trimmer repair for grass with your own hands.
Why is a trimmer not starting for grass
The most common reason that the unit does not start is the use of poor.quality fuel. The choice of gas stamps below AI-92 can disable the lawnical mower. If high.quality fuel is used, you need to look for other reasons. To do this, carefully check all nodes and systems. The checks are subject to:
The device may not start after prolonged downtime. Before turning on a trimmer for grass, you need to study well the instructions for operation. The solution of many problems is indicated in it.
If it stalls when you press the gas
There are several reasons why a trimmer for grass stalls when gas is pressed:
- The first reason is the dumping of the carburetor.
- Fuel valve.
- Fur valve blockage.
- The weakening and sagging of the carburetor cable or sagging of the fuel intake hose.
So that the described problems with the lawn mower do not arise, you need to carefully monitor the condition of the device and its blocks. Timely cleaning, washing of the unit and spare parts allow you to increase its life.
The most difficult breakdown of the starter occurs when the rope is broken and winding it into the flywheel of the operating engine. As a result, the spring may burst and the pulley plunges. In this case, only a complete replacement of the spare part will help. This breakdown rarely occurs. often:
In this case, it is easy to fix the starter yourself. The manufacturer has prepared a step.by.step instruction for this.
Caring for the motorcade gearbox consists in the timely lubrication of the unit. The absence of one can lead to rapid wear of the gear and jamming of the gearbox module.
The main malfunctions of the trimmer gearbox for grass:
- severe heating of the gear component due to the use of low-quality lubrication or its absence;
- shaking of the shaft during the rotation of worn bearings;
- staggering or flowering from the bar of the gear ratio as a result of damage to the case;
- Lack of rotation of the output shaft with a knife due to wear on the teeth on the gears.
Most of the malfunctions in the gearbox are associated with the destruction of bearings.
This happens due to the use of low-quality lubrication or its complete absence. Another reason for the failure of the gearbox is the operation of a trimmer for grass at the limit of its capabilities and the hit of foreign objects. To replace a faulty bearing, a gearbox is disassembled.
Features of the repair of electric models
Electric models of trimmers operating from the network have several main blocks:
Each electrimmer block has specific problems. In the mechanical part, they depend on the presence of a fishing line used as a cutting element. Reasons for the termination of work:
You can identify the problems of the electrical part of the electrocos using special tools:
To eliminate problems, a soldering lamp is needed.
How to adjust the carburetor
The module adjustment is carried out by the manufacturer. During the operation of the device, after repairing or cleaning the module, it becomes necessary to adjust the carburetor.
Carburetor setup does not require replacement of spare parts. Debugging is done with the help of 3 screws that are available in the design:
- L. controls the supply of fuel at low speeds;
- H. controls the fuel consumption and temperature, and is also responsible for supplying gasoline at high speeds;
- T. is responsible for the idle engine.
Adjustment of the carburetor of the trimmer for grass is carried out after the engine warms up. For this, 10 minutes of operation of the device at idle will be enough. The rotation of the mowing head at idle allows you to start directly to debug the screw t. It is turned counterclockwise to the cessation of rotation. Then the screw h is scrolled to the right and left to find the position in which the idle speed will be maximum. The screw is turned off on ¼ full turnover counterclockwise from the found point, this will be the working position.
According to the same technique, the screw l. After repairing the carburetor, the module is necessarily tuned so that the device works correctly.
How to make repair of the lawn mower with your own hands?
Those who have land are very familiar with what struggle is weed.
Especially when it often rains and the grass grows not by the day, but by the hour. Earlier, and sometimes even now, this issue was resolved with the help of a good old braid for grass.
But technologies are not standing still and now in this case, assistants such as electric and gasoline lawn mowers help.
The gasoline mower has several significant advantages over electric, such as mobility and lack of danger of electric shock. But there are many drawbacks, for example: high price, a lot of noise, expensive fuel and significant weight.
Electric mowers are cheaper, easier, work on inexpensive energy, and are not difficult to maintain and repair. These advantages become the main reason for their great popularity among buyers of this type of technique.
But despite the pretty good quality, improper operation and a lot of load, they can disable the device. In such cases, you should not immediately carry the device to the repair shop, but try to find and eliminate the cause of the breakdown yourself. over, as mentioned above, electric lawnmands do not have as many nodes and details as gasoline.
The main thing is to have some tools and faith in yourself. In this article, I will just show you how I did my own repair.
AL-KO, the lawn mower of the company, has serious problems in work, namely: the engine stop without load and its strong overheating, was taken as an example. The motor stops, buzzes and start it again, only repeated pressing the Start button helps. The button has to restart almost every 30 seconds, and with further work and more often.
Of course, you can work, but it is very annoying and gives the feeling that somewhere the problem is. Therefore, I wanted to figure out where?
After the mower was working within an hour, the engine temperature was measured. It was impossible to touch him with a finger. He directly radiated heat. If you continue to pay attention and continue to work on such a mower, an electric motor will inevitably fail.
It is necessary to determine the cause of the motor overheating. To do this, remove the top cover of the case, under which the engine is located and its power chains.
The lid is held on six screws with a hat under a cross screwdriver.
Unscrew these screws and remove the lid. upward.
Having removed it, you can see the impeller, the capacitor, two connectors and the engine itself.
At first glance, no special problems are invisible. The engine winding darkened slightly from the temperature, but so far it is not critical.
To more carefully inspect the capacitor, it is necessary to unscrew the mount and pull it out.
The capacitor of some external damage did not show.
To check it, you need to disconnect the capacitor and feed the engine for a short time. If he did not start and began to buzz, then the capacitor is intact, because the engine was launched with him. Disconnect the power and connect the container connector back to the engine circuit.
Next, try to twist the impeller. It is mounted on the axis of the rotor and rotates rather tight.
And the reason for such severe rotation is a mechanical brake, which for safety stops the engine rotation when the power is turned off.
It looks like a sleeve that moves freely from top to bottom, along the rotor axis.
Когда напряжение на двигатель не подано, эта втулка прижимается верхней частью о крышку, на которой приклеено две резиновые полосы. Thus, the knife is inhibited on the rotor shaft.
When feeding, the brake sleeve under the influence of the magnetic field is drawn to the center of the rotor and provides free move.
With a careful examination, this sleeve with the brake noticed that at the time of turning on the engine, the brake is retracted and gives the shaft free rotation, but after 2-3 seconds it is released again and begins to slow down the motor. This should not be. Hence the stop of the knife during operation and overheating of the engine.
To find out what is the reason for this work, you need to remove and disassemble the engine.
To do this, disconnect the connectors and put the device on the side to get to the clamping screws. Access to them closes a knife with mounting elements.
To remove it, first you need to unscrew the knife bolt (cm. Figure below).
Direction of rotation, like a regular bolt, and not with left thread. That is, unscrew it counterclockwise, and tighten the clock.
The head of the bolt is plastic, so using the key, it must be well planted so as not to “lick” the edge.
After extracting the bolt, the knife and its plastic disk are removed.
Under it is a height sleeve. With its help, you can slightly lower the knife.
Powerworks 40V Trimmer/Brushcutter
Adjustment is carried out by the washers put under the sleeve (see. drawings below).
We remove everything, only the engine shaft and the hexagonal screws of its fasteners remain.
The key for these bolts has a distance between faces of 6 mm. Unscrew them counterclockwise. Removing the last screw, with one hand, hold the engine.
Next, put the mower on the wheels, and clasping the engine with our hands. we raise it.
To disassemble the motor, you need to free tightening studs. We unscrew them all.
Remove the impeller with two screwdrivers.
We proceed to the removal of the back cover. A wooden block and a hammer will help this.
But first you need to mark the position of the covers with something sharp to the engine body.
Put the engine on the side and hit with a hammer, through a wooden gasket, on the rear shaft.
The motor at that moment should hold another person.
We hit until the axis comes out of the bearing to the end.
The engine is faulty
All breakdowns that are possible in the engine are divided into two main categories. The first can be attributed to those that are not possible to fix it independently. For example, it can be a marriage that can only be fixed by replacing the tool. And there is another group of breakdowns that are subject to even non.professional.
So, if the lawn mower operates for more than 15 minutes, then the engine may start overheating. You can fix this by turning off the tool for several minutes.
Qualcast Strimmer GHT600A1 Electric Motor Bushes Replacement
Also, overheating can be initiated by another reason, for example, by the fact that the starter’s grille was clogged, namely, parts of grass and shrub fell into it.
It is extremely important to use only fuel, which is indicated in the technical description for the tool, otherwise, the problems of the carburetor will be overtaken very soon.
When using poor.quality or inappropriate raw materials, it will at least be clogged, and even rust may appear as a maximum. And, therefore, it will not be possible to ignition of the lawn mower and will have to contact specialists.
In some cases, during operation, fuel leakage may be observed. This should not be, since the consequences can also lead to a more serious breakdown. Most often, fuel follows due to the fact that the corresponding hose has clogged, which can simply be blown.
Do.it.yourself trimmer repair
Details: repairing a chamber for Champion grass with your own hands from a real master for Olenord.com.
Modern technologies and technology allow you to produce the best and optimal technical solutions that become effective assistants when arranging a summer cottage or personal plot. Green lawn and other stands can grow rapidly, to put the house mowl is used to put in order and haircuts of lawns, which is differently called a motorcycle or a trimmer, a benzo-core.
Traditional braids for grass are inconvenient and unsafe in use, require significant expenditures and their own forces that will help to save law mowers that combine functionality and practicality in their design. In the photo Benzosos, you can see various high.tech devices that have a complex of operational characteristics, including parameters such as increased performance and long service life.
A convenient and reliable trimmer for grass is a technical device consisting of individual mechanisms, details and elements that can be worn out, become unusable and damaged during intensive operation.
Even when conducting a regular technical inspection, care and care procedures, such devices and their individual parts require repair and even replacements, all repair procedures can be carried out independently.
The easiest way to give the lawn mower for repairs, allocating a certain amount of funds from the family budget, operational and high.quality repair with your own hands is no less simple and convenient to understand the design of the lawn mower and fix all the problems.
The massive and piece manufacture of trimmers is based on the use of generally accepted technology, the typical design scheme consists of certain elements and parts, it is important to know them when carrying out independent repair work:
- top part. The basis of the entire structure, where all important elements are collected, such as the starter, carburetor and the engine of the lawn mower;
- middle part. Hollow rod, inside it is a cable connecting the engine and gearbox, which sets the cutting fishing line for the trimmer. In this part there are mounts for the distribution of weight of the entire structure and a belt for fixing a trimmer for grass on a belt of a person using a trimmer for grass for its intended purpose;
- Bottom part. It has a gearbox and cutting elements that are hidden under a practical casing, which protects the user. The casing provides an increased level of safety, preventing large fractions of garbage, pebbles and glass in a person while working with a gas station.
Knowing the internal device and the principle of operation of the trimmer for grass, you can independently carry out repair measures for the design or replace individual unusability of the nodes using the repair instructions.
The most common and often encountered, subject to independent correction of the breakdown of the unit can be called the following problems:
- engine malfunction, due to which the lawn mower is not started and does not work;
- enhanced vibration of the bar motorcosa, which complicates its targeted use;
- increased overheating of the gearbox, its accelerated heating during operation;
- slow and weak functioning of the cutting fishing line at insufficient speeds;
- the clogging of the starter grill causing the engine overheating and its refusal to work;
- rapid and frequent clogging of the carburetor due to the use of poor.quality fuel;
- clogging of the air filter in case of non.compliance with measures to care for the device.
