Why is a trimmer vibration for electric grass with a knife. Repair of a trimmer for grass for grass with your own…

Why is the vibration on the trimmer

Suppose you don’t start a trimmer for grass. In this case, first you need to check whether the fuel in the tank is enough, also evaluate the quality of the fuel consistency. It is necessary to refuel a motorized unit only with high.quality gasoline. It is recommended to use fuel, the brand of which is not lower than AI-95.

In the near future, the gasoline trimmer for the grass acquired the status of the 1st of the main tools in the arsenal of summer residents. And this is logical, because a motorized braid for grass allows you to quickly put a personal plot in order.

But from time to time it happens that it does not start hot even on a cool. In such situations, it is necessary without the help of others to establish the cause of the malfunction. Let’s find out what to do if a trimmer is untangled for grass.

The reasons that most often lead to such troubles will be considered further.

Electric trimmer for grass vibrates

Many mowing users noticed that some time after the start of the apparatus, it begins to vibrate very much.

On some trimmers, mainly in models more expensive, an anti.vibration system was installed in the form of shock absorbers seized between the engine and the bar. But in some cases, even she does not save from strong vibration.

The reason that strong vibration appears in the trimmer, there may be a small amount or complete absence of lubrication on a hard or flexible shaft located inside the rod of the apparatus.

Replacing the lubrication of the hard shaft is as follows:

unscrew the gearbox located at the bottom of the bar;

After removing the gearbox, you will see the end of the shaft, for which you need to pull to extract 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 lubrication to the shaft and evenly smear it along the entire length of the part, including the slots at the ends of the rod (if they worked, the shaft will have to be replaced);
• After lubrication, insert the shaft back into the bar and put the gearbox in the same place.

The lubrication of the flexible shaft is as follows:

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

This is done like this: first you need to lubricate the end of the cable, and then insert it into the bar, after which, as it moves into the pipe, you should apply grease to the part and evenly distribute it on the surface. Then insert a bar with a flexible shaft into an electric engine and fix it.

In the event that the lubricant did not help, and the vibration continues to appear, you will need to change the flexible shaft.

Sapun and graduation channel

Often, “delicate” branded models of benzos are not launched and stall due. The main function of this element is to align the pressure in the gas tank. When clogging this node, a vacuum is created in the tank that prevents the supply of fuel. Eliminate the malfunction can be cleaned by cleaning the sounds. You can use a regular needle for cleaning.

The normal operation of the cos with internal combustion engines can be disturbed due to the entry of dirt into the exhaust channel or clogging of the muffler grid. There is such a problem on the models of the older generation. You can solve the issue with traditional cleaning and removal.

Electric trimmer for grass vibrates

Many mowing users noticed that some time after the device began to work, it begins to vibrate very much. On some trimmers, mainly in more expensive models, an anti.vibration system was installed in the form of shock absorbers located between the engine and the bar. But in some cases, even this does not save from strong vibrations. The cause of strong vibration in the trimmer can be a small amount or complete absence of oil on a hard or flexible shaft located inside the rod of the device.

Replacing the hard lubrication of the shaft it looks like this:

Unscrew the gearbox located at the bottom of the bar;

Having removed the gearbox, you will see the end of the shaft, which needs to be pulled to remove the part;

After removing the shaft, it must be lubricated with a large amount of special oil “CV Joint-4” or usual. “Litol-24”;

• Apply a small amount of oil to the shaft and grease it evenly along the entire length of the part, including the grooves at the ends of the rod (if they work together, the shaft will need to be replaced);
• After lubrication, insert the shaft again into the stem and replace the gearbox.

Flexible lubrication of the shaft is as follows:

• Unscrew and remove the mowing head;
• Remove the stem from the engine by unscrewing a couple of bolts;
• Pull out a flexible cable from the bar;
• Lubricate the cable along its entire length.

This is done as follows: first you need to lubricate the end of the cable, and then insert it into the rod, then, moving inside the pipe, grease the part and evenly distribute it on the surface. Then insert a flexible motor into the motor and fix it.

complex reasons for the failure of the bush

If a step.by.step algorithm for eliminating problems does not work, and your braid is still not starting and not delayed, you should inspect the carburetor and the engine itself. The cut carburetor may be one of the reasons for the instrument unstable operation. There are three main problems:

• Clogged channels or nozzles. All this is cleaned with special shells or blown by a powerful stream of compressed air from the compressor. Do not use needles or wire, since the passage sections can be damaged;
• The carburetor laying is worn out. Exit. Replacement of faulty gaskets;
• Leaks. To check this indicator, you can use a regular household tonometer by replacing the pressure gauge with the corresponding. Follow the testimony: if they do not change, everything is in order, and if the pressure begins to fall, then some part of the carburetor is faulty. It will be necessary to find it and replace it with a new.

If the carburetor is in order, the gas trimmer for the grass may not start due to wear of the piston group. If chips, scratches or nests are found on the piston or cylinder, they should be replaced. Piston rings are subject to mandatory inspection. A small piston loop while swinging the connecting rod indicates that the time has come to change the rings. This procedure is best entrusted to the specialists of the service center.

Diagnosis and elimination of electric motor problems

Electrimmer malfunctions can be as follows:

To cope with these breakdowns, you do not need to disassemble the entire device.

On a note! Before you start repairs, it is important to prepare the necessary tool: a set of screwdrivers, a tester, a soldering iron, indicator, a set of keys. With serious engine failures, you will have to disassemble it

To do this, you need to unscrew a few screws. Having gained access to the motor details, you need to carry out the following actions:

With serious engine failures, you will have to disassemble it. To do this, you need to unscrew a few screws. Having gained access to the motor details, you need to carry out the following actions:

• Checking the degree of wear of brushes. unsuitable details will need to be replaced with new ones;
• Rall the engine winding. the resistance should be high;
• Check the stator and rotor. to test the rotor winding with a multimeter, measure the resistance: large deviations from the norm indicate a malfunction, the absence of resistance on the stator winding also indicates a breakdown (the same way is diagnosed with the stator case).

Advice! The solution to problems associated with faulty electric nodes are associated with great difficulties. Often it is easier to replace them with new details than to take time for rewinds.

Low.speed problems are a common phenomenon for cheap trimmers. However, with improper maintenance, such manual mowers as Huter, Patriot 3055, Echo also suffer from this.

Filters

Blocking air filter ─ another reason for the unreliable operation of the device. To check the involvement of this element in the malfunction, you need to start the lawn mower without it. The contaminated filter can be washed in gasoline, dried or replaced with new.

The clogged fuel filter does not let the fuel into the cylinder, and the engine with full gas stalls due to elementary lack of gasoline. This element is located inside the tank on a fence hose. To eliminate the problem, instead of the old filter, put on the new hose or rinse carefully the one that was removed.

Advice! When trying to pull out a cork in the tank, the hose along with the filter can fall into the tank. You can get them with tweezers.

technical issues

The technical problems of the lawn mower mainly occur in the fuel and ignition system. You can cope with them yourself.

• Когда ручная косилка не заводится или глохнет, проблема может быть связана со свечой. The dark cargo speaks of poor carburetor adjustment and low gasoline quality.
• The reason for the incorrect operation of the trimmer for the grass may be clogged fuel hose. Filters are also often clogged.
• Another internal problem. the muffler is covered with soot. From this, the turnover of the grass for the grass falls strongly. Output. you need to clean the muffler.

Important! If the unit does not work due to breaking up the engine, serious problems may occur. In this case, the malfunctions that can be eliminated with your own hands include only the destruction of piston rings

With more serious problems with the motor, if there is no warranty, you should be prepared to visit the workshop.

Then insert a bar with a flexible shaft into an electric engine and fix it.

Repair of the carburetor

During the inspection of the carburetor, it is worth paying attention to the possible course of the fuel used, to identify the problems of the carburetor, the following measures must be carried out:

• fuel hose purging to eliminate the possible clogging of the element;
• checking and replacing the gasket located between the engine and the carburetor;
• determination of tightness and maintaining constant pressure in the unit.

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.

The main malfunctions of gasoline and electric trimmers

If you do not take into account damage associated with the bar and mowing head, the bush and electric trimmer for grass usually cause malfunctions in the engine.

Damage to gas trimmers

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

• Engine breakdown;
• Problems with the carburetor;
• Fuel supply problems;
• Muffler malfunction;
• Gear breakdown;
• The starter is broken;
• Air filter problems;
• Cut the fan on the gas tank.

Defective electric trimmers for grass

Since the device of an electric mower is much easier than a trimmer for engine grass, there are little reasons for its failure.

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

• Electric cable malfunction;
• Faulty control button;
• Winding of the burned engine stator;
• Open contact on the engine.

Features of the work of a trimmer for grass

All trimmers for grass are classified according to the type of power: gasoline or electricity (from the network or battery). It should be noted that gasoline mowers in many respects exceed their electric and battery analogues. Despite the fact that they all perform similar functions, the difference in performance, maneuverability and effectiveness is very noticeable. However, the general principle of operation of all types of manual braids is almost no different- the devices are equipped with engines (two- or four-stroke ICE or electric motors), which drive the cutting unit (reel with fishing line or metal disk). All elements are fixed on the line of straight or curved shape, including the handle for controlling the trimmer on which the main buttons are located.

Since the problem of weak revolutions is more characteristic of gasoline trimmers, they will be given more attention. So, the lawn mower is very comfortable in work and unpretentious in maintenance

over, most of its malfunctions are caused by ignorance by the user of elementary things, which are written in the instructions. Therefore, before starting the operation of the unit, it is necessary to carefully study the management of the manufacturer. In particular, in order to start the engine, it is necessary to do the following sequential actions:

• turn on the ignition button;
• press the silicone button for pumping gasoline several times;
• close the air damper;
• The gas lever is installed in a position for high speeds;
• first make non.leaf with the starter handle to feel the engine resistance, then jerk sharply.

If the lawn mower started up, but stalled, you need to put the air damper in the middle position and repeat the attempt. When the engine works, you need to slow the gas and open the air damper, since the trimmer for the grass functions only on the leak.

How to disassemble a gearbox of a trimmer for grass

In order to disassemble a trimmer gearbox for grass, you need.

• Remove the gearbox from the pipe, loosening two conjugate bolt under the gearbox.
• Wash the gearbox with a brush, for example, in gasoline without oil and dry.
• Run the ends of the locking ring and take it out.
• The second stop ring and the second.
• Then it is necessary to heat the trimmer gearbox for grass, the motorcosa gearbox or the reducer of the lawn mower by an industrial (technical) hairdryer at the temperature of the outgoing air at 600 ° C.
• After that, strong blows of a wooden bar on the upper part of the gearbox, knock out a driven shaft with a bearing and a gear (first you should try to knock out bearings without heating). It is only necessary to hit a wooden bar, since a metal, for example, with a hammer, can be broken down by the case.
• In the same way we remove the leading shaft with a bearing and a gear (we strongly heat the place where the bearings are sitting and with the blows of the wooden bar on the body of the shaft, we knock out the shaft with two bearings and the gear). How to disassemble a trimmer gearbox for grass, gearbox gearboxes and gearbox motokos. In order not to heat, you can try to use the set.

The assembly of the gearbox of a trimmer for the grass is carried out in the reverse order of disassembly (assembly after buying and replacing spare parts). It is much easier to collect a gearbox than to disassemble. everything is going, literally, with fingers. Sometimes you need to gently take up something, install stop rings and check whether the driven shaft is spinning by hand.

If you decide to replace the trimmer gearbox for the grass with not original, then in the new gearbox you should pay attention to the diameter of the pipe for which the gearbox (more than 25.4 mm or 26 mm) is intended, the diameter of the drive shaft (more than 8 mm), the size of the square shaft square (more often 5 mm or a star for 9 teeth) and security mounting on the gearbox, as well as on a nut (with left thread, more often M10x1.25).

Law out.handies malfunctions and ways to eliminate them

At least what type of benzos has a half bar, in which the binding cable between the motor shaft and the lower gearbox is placed, which transfers rotation to the tool with cutting inventory. In the highest part there is a carburetor and a motor, a gearbox and a working tool closed by a casing are placed on the bottom. In the middle part there is a transverse handle when the control buttons are placed. To unload the hands, there is an unloading belt holding the bar with a torso of the operator.

In the process of choosing a lawn mower, a device with a two.stroke engine is better than a four.stroke. Two.stroke engine is more maneuverable and easier to repair. With a four.stroke node below the level of vibration.

This follows, repair of the lawn mower is to eliminate defects;

• the engine does not start;
• The cutting mechanism does not develop;
• the engine stalls;
• the gearbox is heated;
• a third.party knock, powerful vibration of the bar is heard.

For now, eliminate the malfunction, it is necessary to diagnose, find a non.working node.

Know the point of lubrication of the tool in principle. Unchanged care, cleaning the device after work will allow you to extend its service life. Before starting work, you need to tighten the fasteners, cook fuel and season the tank.

DIY lawnies repair: analysis of malfunctions and methods for 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 comply with 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. 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.

The trimmer is very hot for the grass causes

The gearbox of a trimmer for grass. malfunctions, prerequisites and methods of elimination

Reducer Trimmer for grass (lawn mower gearbox, motorcade gearbox) is a mechanical device located in the lower part of the trimmer for grass (lawn mowers or motorcycles) and created to transmit the rotational moment from the engine to cutting equipment at an angle of 30 °, ensuring the operation of the cutting equipment in horizontal planes (parallel to the surface of the earth), also reducing the angular speed and increasing the torque of the output shaft in a ratio of 1: 1.40 (for example, if the engine operates by 12 thousand. rpm., then the knife will spin at a speed of 8.6 thousand. rpm).

Possible malfunctions of a trimmer gearbox for grass, a gas mowing gearbox, and gearbox Motokos

• Malfunction. the gearbox of the trimmer for the grass is very heated. The malfunction of the reducer of the lawn mower and the gearbox Motokos is the same as that of a trimmer for grass.The causes of the malfunction are the lack of lubrication in the gearbox, the inappropriate lubricant or the unwell of the new gearbox (when the details have not yet grown off). Trimmer repair for grass with your own hands. add a lubricant to the gearbox of a trimmer for grass, change the lubricant or run up to a trimmer for grass in a sparing mode (develop three fuel tanks with small loads and with repeated stops for natural cooling).
• The trimmer malfunction for grass is a knock, free course and sequeling when rotating the shaft of a trimmer gearbox for grass, gearbox Motokos or a reducer of a lawn mower. The causes of the malfunction are the destruction of the 1st of the bearings in the gearbox of the trimmer for the grass due to the lack of lubrication in the gearbox, an inconsistent lubrication, the hard criterion for the operation of the grass for the grass, damage to the anthers on the bearings when installing them. Repair of a trimmer for the grass with your own hands. order bearings from the dealer and change them (there are two or three closed bearings). for more details see. Below “How to disassemble the gearbox of the trimmer for grass / Gearbox gearbox / Reducer Motokos”.
• The trimmer malfunction for grass. the gearbox staggering or flies from the trimmer pipe for grass. The causes of the malfunction are mechanical damage to the gearbox body. for example, if a piece of housing is broken off when a knife is severely hit on a heavy metal or stone (or if the gearbox is destroyed, for example, a hammer during repair). Do.it.yourself trimmer repair. change the gearbox body. Or, if you have broken off a small piece, make an iron clamp tightening the place of fault. Do.it.yourself renovation of a trimmer for the grass is repaired with your own hands.
• The trimmer malfunction for grass. the gearbox on the pipe is not clamped. As practice indicates, completely gearbox does not fly off the pipe, but at the theoretical level. it can fly off the pipe, coupled with a rotating knife. A lawmaker’s malfunction is like a trimmer.The causes of the trimmer malfunction for grass are the wear of the gearbox planting place on the pipe (the aluminum of the pipe is expired under the gearbox). Do.it.yourself trimmer repair is repairs. to drain a cloth isolet to a pipe under a gearbox or change the pipe.
• The trimmer malfunction for the grass. the trimmer knife for the grass did not spin at all (with the corresponding iron sound) or stops spinning at large loads (with hard blooming sound). The causes of the malfunction are the wear of the teeth on the conical gear in the gearbox of the trimmer for grass. Trimmer repair for grass with your own hands. change the pairs of conical gears (a pair is replaced) in the gearbox. for more details see. Below “How to disassemble the gearbox of the trimmer for grass / Gearbox gearbox / Reducer Motokos”.

How to disassemble a gearbox of a trimmer for grass

In order to disassemble the gearbox of a trimmer for grass, you need.

• Remove the gearbox from the pipe, loosening two conjugate bolt under the gearbox.
• Wash the gearbox with a brush, for example, in gasoline without oil and dry.
• Run the ends of the locking ring and pull it out.
• Extract the 2nd stop ring in the same way.
• Then you need to very much heat the trimmer gearbox body for grass, gearbox Motokos or gearbox of the lawn mower by a factory (technical) hairdryer at an outgoing air at 600 ° C.
• After that, the strong blows of the wooden bar on the highest part of the gearbox body, knock out the driven shaft with a bearing and a gear (at first it is worth testing the bearings without heating). It is necessary to hit only from the woods, because with iron, for example, a hammer can be broken by a hammer.
• In the same way we remove the leading shaft with a bearing and a gear (we are very heated by a place where the bearings are seated and the wooden bars on the body of the shaft are seated, we knock out the shaft with 2 bearings and gears). How to disassemble a trimmer gearbox for grass, gearbox gearboxes and gearbox motokos. In order not to heat, you can experience the setting.

lawn mower. He stalls hot. Possible reason and elimination.

I immediately draw your attention that it is not a carburetor to chagrin. (My website

Eliminate overheating on the chainsaw

For the sake of experience but the continuation should be tested in front.

The assembly of the gearbox of a trimmer for the grass is done in the order of the revolutionary disassembly (assembly after the purchase and replacement of spare parts). It is much easier to collect a gearbox than to disassemble. everything is going, practically, with fingers. From time to time, you need to take up something lightly, install stop rings and check whether the driven shaft is spinning by hand.

If you decide to replace the trimmer gearbox for the grass with not original, then in the new gearbox you should pay attention to the diameter of the pipe for which the gearbox (more than 25.4 mm or 26 mm) is intended, the diameter of the drive shaft (more than 8 mm), the size of the square shaft square (more often 5 mm or a star for 9 teeth) and security mounting on the gearbox, as well as on a nut (with left thread, more often M10x1.25).

How to lubricate a trimmer gearbox for grass / Gearbox gearbox / Reducer Motokosa

Lubricate a trimmer gearbox for the grass at least once a year, but it is better to inspect the lubricant after every 20-25 hours of work or when the gear noise in the motorcade gearbox appears. How to lubricate the gearbox gearboxes. For lubrication, at first you need to clean the cork itself and the place around the traffic jam and the remnants of the grass, so that they do not fall inside the gearbox when filling it with grease. Then you need to turn out the cork for the lubrication of the gearbox (for example, the Echo lawn mower is a key for “17”, in Husqvarna-a 6-garnet on “5”, for Chinese lawn mower-the key on “12”). It is better to use the same manufacturer as your trimmer for grass or just from world-famous brands, such as Oleo-Mac, Stihl, Husqvarna, Oregon, Liquimoly, Litol-24, Azmol 158 and T.D., If only it was not a fake! The tube, if new, print, removing with your fingers a cork or piercing the cover with the back of the lid in the nose of the tube. Then we put a trimmer for the grass on the left side, and rotating the knife with one hand (so that the gears are smashed and the entire volume is filled), squeeze the lubricant from the tube with the 2nd hand through the hole inside the gearbox before its full filling. Then we twist and clamp the trimmer gearbox for the grass and a tube plug with a lubricant. If the lubricant is not in the tube (and, for example, in the jar), take a honey syringe without a needle, take out the piston, fill the lubricant (with your finger) in the syringe, and then fill the gearbox of the trimmer for the grass from the syringe from the syringe.

Law out.handies malfunctions and ways to eliminate them

Any type of benzos has a half rod in which the connecting cable is placed between the engine shaft and the lower gearbox transmitting rotation to the working organ with a cutting tool. At the top there is a carburetor and a motor, below is a gearbox and a working tool closed by a casing. In the middle part there is a transverse handle in which the control buttons are located. To unload the hands, there is an unloading belt holding the bar with a torso of the operator.

This follows, repair of the lawn mower is to eliminate malfunctions;

• the engine is not launched;
• The cutting mechanism does not gain momentum;
• the engine stalls;
• The gearbox is heated;
• an extraneous knock, strong vibration of the bar is heard.

Before eliminating the malfunction, you need to diagnose, determine the non.working node.

It is important to know the points of the tool lubrication. Constant care, cleaning the device after work will allow you to extend its operation

Before work, it is necessary to tighten the fasteners, cook fuel and season the tank.

Engine mount, pillow check

During the diagnosis, it is necessary to pay attention to the support, which is a kind of gasket between the motor and body details.

The support can be hydraulic or rubber.metallic, it is necessary in order to soften vibrational vibrations that appear during the operation of the power plant, are transferred to the body and far from the best effect on comfort while driving.

In the vast majority of cases, the engine is attached using 4-5 supports, and if at least one of them is faulty, this immediately manifests itself in the appearance of excessive vibrations. As a rule, the breakdown boils down to a break in a part made of rubber and metal.

How to check the pillows

To do this, you can use one of two methods. The first is the simplest, but also the least informative. It boils down to the following: you need to open the hood, ask someone to start the motor and slowly move the car from the place, drive about 10 meters at the minimum speed, then turn on the rear gear and drive back.

If a change in the position of the power plant is detected during the change in the direction of movement, as well as if the vibration intensifies, its cause lies precisely in the pillows. The described verification method is most informative if there is a breakdown of the upper (right) support. When failing at once, several pillows at once or to detect defects in the lower work, it is advisable to use the second diagnostic method:

• The part of the car where the engine is installed is raised to the jack.
• Reliably fix the structure using pads or other supports.
• Hang the engine, removing the load from it from the supports.

In this case, special attention must be paid to the seams, the places in which the metal parts are connected to the rubber. If defects were found during diagnosis, most likely you will have to replace the engine pillows

On idle

When the engine works fine, the vibrations are minimal. It should also be taken into account that in the cold season, when “overboard” the minus temperature, “shaking” is more noticeable.

It is especially noticeable immediately after starting the motor. After a few minutes of work, after warming up, it almost completely disappears. At the same time, there should also be no talk of any failures, jerks, as well as the appearance of extraneous sounds.

The trimmer for the grass is very hot

Overheating of a trimmer for grass can occur for many reasons:

• Gasoline has not the same octane number indicated in the instructions for the unit;
• the proportions of gasoline and oil during the preparation of the fuel mixture are not observed;
