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:

  • conical;
  • worm;
  • spiroid;
  • cylindrical;
  • planetary;
  • wave;
  • combined.

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.

Cycle: what mistakes of beginners lead to breakdown of the engine of the trimmer for grass and exclude its normal operation

6 common mistakes with fuel

The manufacturer in the instructions clearly indicates the brand of gasoline with an octane number, oil and their proportions.

The first three errors are that the user of motorcycles violates all or one of these requirements. The motor will most likely start and work, but its resource may decrease sharply.

A small amount of oil, like its absence, will lead to the fact that the walls of the cylinder will not grease normally, and the piston rings will scratch them, and not slide.

Excess oil will simply burn, forming soot. She will pollute everything, including the piston and cylinder.

Failure gets into the valve, blocks their work, after which the motor will not start.

Will have to disassemble and clean the carburetor, or even put a new. Of course, you can try to wash the piston and the cylinder: it may be possible to bring them into working condition, but it is better not to bring them to.

The fuel mixture must be prepared with high quality and in strict proportion. The repair of a spoiled engine is expensive, about 70% of the price for a new gasoline trimmer for grass.

For the preparation of high.quality fuel mixture, I have a special container with a factory division of divisions in a set of trimmer for grass. Gasoline is neatly poured into it to the level of 500 ml, and then the oil to the required label.

An alternative method is the preparation of a fuel mixture with filling gasoline into a calibrated container, for example, a liter canister or a plastic bottle to a label, and an additive of oil with a medical syringe according to its divisions.

The dosage with a syringe is more convenient, is considered the most popular way.

I recommend filling gasoline through a funnel with a narrow neck that has a filter: a metal mesh. protection against small garbage.

The prepared mixture should be well shaken and mixed until a uniform color appears. Only after that it can be poured into the tank.

If the mixture does not blame, then it will remain in the tank, and through the carburetor will enter the combustion chamber in portions with different ratios of gasoline and oil.

Fractions of clots of oil clog a candle. The motor stops, stalls, does not start. This is the fourth mistake of beginners.

It should be borne in mind that gasoline is hazardous. The risk of fire exists. Therefore, it is necessary to fill the mixture at a safe distance from the buildings, and in the case of the strait, which often happens to eliminate the causes of a possible fire. Violation of fire fighting measures. error

After pouring the fuel into the gas tank, the latter closes with a screw plug and the lack of leaks is checked. The trimmer for the grass is raised up so that the gasoline fills the cork. There should be no subterations from under the lid or from the fuel hoses.

Lack of such a check. an error can cause a fire.

There is one technical cunning that can cause a benzotrimer motor is not started due to the cessation of fuel supply. If you look carefully at the center of the traffic jam, then a round hole is clearly visible.

We turned Motokosa. Gasoline filled the cork, but does not flow through the hole: there is a sapphone inside. He is working.

On the inside, its design is clearly visible: a valve system of plastic and rubber is built.

In the usual state, the valve is pressed to the hole and the fuel does not flow. Когда бензомотор работает, то топливная смесь расходуется через карбюратор. A vacuum is created in the tank. The vacuum opens the valve of the saapon, the pressure is restored.

You should know the two consequences of a malfunction of the sapuna:

  • Constantly open hole. fuel pours out of the tank during its inclinations (excess consumption and the probability of fire).
  • Contamination or sticking of the valve channel is the reason that the lawn mower does not start or stalls.

Check the soundtress is easy: you need to blow it in both directions.

All about the gas tank cover, including the repair of the saapun, is shown in the video of Bogdan Shabanov.

3 additional advice associated with limited chemical resistance of a mixture of gasoline with a small one:

jammed, trimmer, motor, grass
  • Do not create an excessive fuel supply. Use freshly prepared fuel mixture. In a maximum of a couple of weeks, she will lose her useful qualities;
  • Prepare as much fuel as it will go to one mowing during the day. At the end of the work, drain the rest from the gas tank and burn the last drops from the fuel canal with a neglected engine;
  • It is especially dangerous to leave the mixture in the gas tank for a long time. winter. In the spring, you will make sure that the engine does not start without cleaning the carburetor (gasoline evaporated, the oil thickened and glued the valve).

In more detail, the technology for eliminating these malfunctions shows in its video video “Chinese lawn mower is not started” Sergey Lesnik. Pay attention to the fuel filter.

To adjust the work of the carburetor allows a special screw, but it is not worth it to twist it without need: the factory adjustment is accurately exhibited. It is better for novice users to contact the service center.

Additionally, it is worth considering that the fuel system malfunctions can occur in hinged equipment when the throughput is disturbed:

Hello. Question to the masters, to those who are in the know, tell me how many revolutions per minute the native collection engine of the minimum of the Huter W105-AR minimum, and the like with the same engines. The engine burned down, and I don’t want to buy a new one, which also burns. The asynchronous engine of 1.1 kW 2900 revolutions was striking to the driven gear of the pump. The pressure appeared, but some kind of weak, the other day, the manometer is so thrust and see how much it presses. When the trigger is released, it turns off, the start-stop valve immediately works. And in the working mode weak. Huter said that the manufacturer does not give information such. I need to find out how much revolutions in my native engine in order to calculate by the transfer number, how much the speed is reduced on the driven six. How the sinks with asynchronics work the same. Thanks

P.S. I already ordered a laser tachometer to measure the momentum of the collector engine on an approximately the same device. Just wait until the package comes for a long time, maybe someone knows how much revolutions there.

Carburetor Carburetor

If you need advice on professional cleaning the carburetor, check out this article. In it you will learn how to clean the carburetor of a two.stroke engine and under what circumstances you may need to clean it. The carburetor of a small engine is usually cleaned when the carburetor is restored, but there are a number of reasons why you may need only to clean it.

Proper cleaning of a two.stroke engine carburetor implies a complete disassembly and assembly of the device. The steps are explained below how to disassemble, clean and assemble the carburetor of the two.stroke engine.

Advice! There are many small details in the carburetor. Keep the details in a convenient manner for you to make assembly quickly and accurately.

Unscrew two screws that attach the lower cover to the carburetor body. On some models, the lower cover is attached by four screws.

Remove the diaphragm and layout of the diaphragm and divide them if necessary.

The diaphragm will be easily disconnected after you remove the lower cover.

The diaphragm laying often adheres to the diaphragm, therefore, if they are glued, they must be divided for subsequent careful cleaning.

Remove the needle valve mechanism.

The needle valve mechanism consists of three parts: needles, lever, and springs. It will be seen after extracting the diaphragm.

The mechanism of the needle valve holds a ktykvetzhny screw. Unscrew the needle valve screw to extract the mechanism from the carburetor housing.

jammed, trimmer, motor, grass

Make sure that the spring remains in place after you remove the screw. She can fly out and you will lose several important valve details with her.

Do not forget to fold the carburetor parts in order during disassembly.

Disconnect the primer and the plate holding it.

The primer holds the plate screwed with two screws in the case. Unscrew two screws that hold the plate.

Remove the base of the primer and the plate valve of the carburetor.

By unscrewing the screws, you will free the base of the primer from the carburetor housing.

Put it aside for cleaning. Look at the thin plate valve between the base of the primer and the carburetor body. Carefully disconnect it: it is very important for the proper operation of the device and requires careful handling. If you damage it, then most likely you will have to change the entire carburetor completely.

That’s all! You completely dismantled the carburetor of the two.stroke engine and all parts of this device are now ready to clean.

You will need the following to clean your carburetor:

The cleaning procedure for each part of the carburetor is approximately the same and consists of the same steps:

Clean the outer part. 2. Clean the inner part. 3. Dry the parts. four. Be very careful with sensitive parts.

Start with the carburetor case and do not be afraid to use a lot of cleaner.

Clean all holes in the case and the paths along which fuel passes.

Dry the body thoroughly with compressed air (if available) and put it on a towel to continue drying.

Go to other parts of the carburetor.

The internal holes of the primer require cleaning, as well as the holes on the carburetor body.

There are several parts of the carburetor that need additional consideration and specific cleaning, including a plate valve, a mesh filter on the case, and the diaphragm. The plating valve must be cleaned very carefully. Use less cleansing unity so as not to damage the details.

Quickly dry the plate valve and put on a clean towel. Many carburetor designs include a small mesh filter on the case. This filter is easily damaged when removing. It is better to leave it in place if there are no replaceable filters. The diaphragm is another part that requires delicate cleaning. The diaphragm is made, as a rule, of rather thin rubber, so if there is no spare at hand, it is better to clean it only with extreme necessity.

The needle valve has a bifurcated shape. The upper part of the needle should enter the bifurcated part of the valve, as shown in the figure below.

Replace the needle valve spring.

Just place the spring back in its slot in the carburetor case.

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);

Engine Teardown. Another One Bites The Dust!

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.

Starter assembly

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.

Spring tension

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.

Useful videos

Below we bring to your attention several videos about the reasons why the lawn mower is not started, and about the ways to eliminate them.

The reasons why the lawn mower is not started or poorly starts “hot”, and what to do:

The analysis of the situation when there is a spark, and the gasoline trimmer for the grass does not start:

How is a trimmer for grass equipped with a disk?

To determine the reason why the gear circle does not rotate, although the electric or a lawn mower is turned on, it is necessary to consider how a trimmer is arranged for grass that can work with such a cutting tool.

The basis of any device is the engine.

It can be electric or gasoline, but the principle of its operation is the same. after turning on, it begins to rotate the shaft with a certain speed.

Most of the electric models are equipped with a button (key) on/off, and the revolutions are determined by the design of the motor and the driver feeding it.

Gasoline devices are equipped with an internal combustion engine, the revolutions of which depend on the load and position of the gas key.

To the motor directly (electric) or through centrifugal clutch (gasoline), the shaft of the bar is connected, which can be both solid and collapsible.

The opposite end of the shaft is connected to the gearbox that turns the axis of rotation so that the disk spins parallel to the ground, and the device itself is located as convenient for the operator.

A reliable connection of the shaft with the engine and the gearbox is provided by square.shaped tips.

If the shaft is collapsible, then the same tips provide reliable adhesion to both parts of this element.

We also recommend that you carefully read these articles:

The causes of the malfunction

Since all the trimmers for grass that can work with the disk are arranged the same way, the reasons why the gear circle does not rotate with the motor turned on are also the same, that is:

  • The fixer in the gearbox is forgotten;
  • licked slots of the protective washer of the gearbox;
  • the engine is turned on, but does not work;
  • clutch on gasoline devices;
  • the shaft tips were erased;
  • The shaft burst or broke;
  • Reducer is destroyed or jammed.

The fixer in the gearbox is forgotten

This is not even a malfunction, but a consequence of the inattention of the operator, who for any reason was removed by one and put the other cutting tool. Inspect the gearbox, if it has a latch, then you forgot to pull it out.

Remember, the inclusion of an electric engine with an installed latch can lead to an inter.flip circuit, although the launch of a gasoline power unit is safe, because at idle speed the clutch turns it off from the shaft.

Licked slots of the gearbox protective washer

If the disk rotates at least a little, but stops from any load, while the clutch of a gasoline trimmer for the grass is completely regular, then remove the cutting tool.

Then remove the protective washer of the gearbox, which is also called the lower slotted plate.

Inspect the slots on it and on the gearbox shaft. If their faces are licked, then the puck needs to be changed, and the gearbox is repaired. If the edge of the slots is clear, then the problem is in some other.

The engine is on but does not work

The owners of the electric focus are faced with this problem, because their engine works much quieter than a gasoline power unit.

To make sure of the electric motor, turn it off, and then turn it on again, while the trimmer for the grass should jerk a little around your shaft.

In addition, an air flow should come out of the ventilation windows. If all this is, then the power unit works normally, which means that the problem is not in it.

The main sign of the operation of the gasoline engine is a characteristic sound that appears after starting the unit.

Clutch clutch

The lawn mowers are equipped with a centrifugal clutch, which works when the engine reaches certain speeds.

The pads are attached to a rotating basis with one side, the second edge is held by a spring, the elasticity of which determines the speeds at which the clutch will work.

When the friction pads of the pads are worn out, they do not transmit the torch of the bar to the fullest, which is why the disk either does not spin at all, or spins very slowly and stops at any load.

If the cutting tool is spinning and does not stop during the mowing of the grass with an increase in speed, then everything is in order with the clutch.

If the tooth circle does not rotate at any engine speed, then the problem is not in the adhesion.

After all, even with completely erased friction lining, it transfers to the shaft at least a little energy, so that the cutting tool, albeit slowly, but rotates.

The shaft tips were erased

This is the most common problem, because when working with the disk, the tips experience huge loads, and incorrect assembly after service accelerates their wear.

To check the condition of the tip, disassemble the shaft, disconnecting it from the engine and taking off the gearbox, as well as dismantling it, if it is provided for by the design.

Inspect the tips. If the faces are clear and they are deeply included in the clutch and gearbox, then the problem is not in them.

Burst or torn the shaft

Devices with a twisted shaft are not designed to work with a knife or disk, but their owners sometimes neglect this requirement.

To make sure that the shaft is working, separate the bar and start the engine if the tip rotates, then everything is fine.

Then remove the gearbox and check the second part of this part. If the rod is indispensable, then immediately remove the gearbox. The lack of rotation of the tip, as well as its torn movements with a change in revolutions indicate that with the shaft of the problem.

Reducer is destroyed or jammed

If all other reasons are excluded, then the problem lies in the gearbox that is destroyed or jammed. Remove the gearbox and pull the shaft from the bar, then insert it into the gearbox and cram it several times, holding the output shaft with your fingers.

If the rotation is transmitted normally, without jerks, then bring a trimmer for the grass home and there completely disassemble this mechanism.

This is the only way to check its real state and evaluate the degree of wear. Remember, even if you recently smeared it, it is better to rinse all the details in diesel fuel and lay a new lubricant, this will extend the service life of parts.

If the gearbox is serviceable, but the disk still does not spin, then you need to check everything new, because somewhere you missed something.

Benzotrimmer loves cleanliness. It is necessary to monitor the purity of the air filter and fuel. It is better to defend gasoline bought at a gas station for 2 days and pass through the simplest filter. a piece of bike matter.

We check the electrical equipment as follows:

We unscrew the candle, examine the gap between the electrodes. We set the right gap between the electrodes can be a “grandfather” way. We take a blade from a razor, scraps in half and insert a home.made probe between the electrodes. If the blades enter tightly, then the gap is perfect.

We put on a candle cap of a high.voltage wire and lean the candle against the metal surface of the engine. Twist several times by the starter. If the spark beats well at one point, then the gap is adjusted correctly. If not, the spark is weak or “wanders”, then it is necessary to re.adjust the gap between the electrodes.

Also, the ignition coil can be broken in electrical equipment. In this case, the lawn mower will not start or start and works with interruptions, and then stalls, or “hot” does not start at all.

You can check the serviceability of the coil in the same way as when checking the spark: we unscrew the candle, lean it against the trimmer body for the grass. If there is no spark with a jerk of the starter, or it appears through time. you need to change the coil.

Why the motor stalls?

We made a brief review of situations when the lawn mower stalls in certain conditions, as well as a list of possible reasons.

In the vast majority of cases, it is possible to eliminate the causes of an unplanned stop of motorcycles only in the workshop, even if it is located in your garage, but even understanding the correct order of action will help to quickly find the source of the problem.

When pressing gas

To determine the reason why the benzotrimer does not start or stall when you press the gas, act like this:

  • Check the condition of the saapun;
  • Check the condition of the fuel hoses and filter;
  • Try to adjust the fuel supply at high speeds using the corresponding screw.

If all this did not help, it is necessary to disassemble and rinse the carburetor, as well as look for an air leak.

At high speeds

To determine the reason, act like this:

  • Make sure the soundtress works fine;
  • Check the hoses and the fuel filter, perhaps they are clogged with dirt;
  • Increase the fuel supply using the corresponding bolt on the carburetor;
  • Check the condition of the candle;

If these actions did not help find the cause, look for air leaks and check the carburetor, maybe it works incorrectly or clogged with dirt.

On idle

If a trimmer for grass stalls in idle, but gains momentum and mows grass, then there are only two possible reasons:

To check and exclude the first malfunction, try to increase the fuel supply with an idle screw, if the adjustment does not give a result, remove the carburetor and look for the air leakage site.

Does not gain momentum and stalls

Here is a list of possible reasons that the device is not gaining momentum:

  • old exhausted gasoline;
  • Dirty air filter;
  • clogged sapun;
  • clogged fuel hoses and filter;
  • faulty or dirty candle;
  • Air suction between the carburetor and the engine.

Starts and stalls immediately

The reasons that the benzotrimer starts up and stalls immediately: can be:

  • Dirty fuel filter;
  • clogged sapun;
  • clogged with mud or damaged carburetor;
  • damaged vacuum hose connecting the engine carder or carburetor.

After warming up

If the lawn mower stalls a few minutes after the start of work, then most likely the reason is:

Under load

Sometimes the lawn mower stalls under load, that is, in the process of work, here is a list of possible reasons for such a malfunction:

  • clogged gasoline hoses or fuel filter;
  • Dirty air filter;
  • Coopy covered with soot;
  • exhausted fuel;
  • air leakage;
  • clogged with mud or a resolved carburetor.

How to avoid breakdowns of motorcycles?

The only way to avoid situations when the gasoline trimmer for the grass stalls spontaneously is the proper maintenance of the apparatus, which we talked about in this article.

Make Your Lawn Tractor Look New Again With A Good Clean!. Video

Timely carry out all the regulatory work, and during the inspection and check of the trimmer for grass, be as meticulous as possible, this will find the problem before it begins to influence the operation of the apparatus.

Remember. all gasoline motors that are installed on motorcycles are arranged so that they cannot stop working without a serious reason, so after even a single spontaneous engine stop, do complete diagnostics.

Electric trimmer for grass vibrates

Many mowing users noticed that some time after the start of the apparatus, it begins to vibrate very much. On some trimmers, mainly in models more expensive, an anti.vibration system was installed in the form of shock absorbers seized between the engine and the bar. But in some cases, even she does not save from strong vibration. The reason that strong vibration appears in the trimmer, there may be a small amount or complete absence of lubrication on a hard or flexible shaft located inside the rod of the apparatus.

Replacing the lubrication of the hard shaft is as follows:

  • Apply a small amount of lubrication to the shaft and evenly smear it along the entire length of the part, including the slots at the ends of the rod (if they worked, the shaft will have to be replaced);
  • After lubrication, insert the shaft back into the bar and put the gearbox in the same place.

The lubrication of the flexible shaft is as follows:

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

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

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

The trimmer for the grass is very hot

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

  • Gasoline has not the same octane number indicated in the instructions for the unit;
  • the proportions of gasoline and oil during the preparation of the fuel mixture are not observed;
  • A mixture of fuel with butter has long been prepared (the mixture cannot be stored for more than 2 weeks);
  • The trimmer for the grass works more than the time instructions;
  • A low.power trimmer for grass on thick and hard grass is used, the device works with overload and quickly heats up;
  • shifted towards the bar or the cassette lid clutched.

The latter occurs if you install a mowing head inappropriate for this unit, or when the axis shifts inside the bar. These changes make it difficult to rotate, the load on the engine increases, and it overheating.

Repair of the lawn mower. (changed, added).

So, dragged a benzo-cos, with symptoms: grasps but does not work.They pulled, her seals for about an hour. I say: Well, if, the maximum of the 5th time did not start, then the matter is clearly not in Babin, rather in the gasket.))).Sent deer behind beer. He said the repair price, they were compiled, although they twisted with nozzles for a long time))).

So. Disassembled. He made the Rotor’s shooter. Why do you need the Rotor’s shooter, but at least in order to remove the rotor normally. Those who write from “” Bat and nah shooter, I do not advise doing this: break the case, or the rotor will crack, bite the tsapfu or kill the tsapt carvings to death))).The procedure for detecting malfunctions in any benzoca or chainsaw:. check whether the spark is present. Should be strong and with smooth scrolling by the starter. If there is no spark, check the wires (on \ off), the candle itself and of course the short circuit itself. Often, due to broken bearings, the magnetic part of the coil sensor clings the rotor. When installing the ignition coil back, between the rotor and the coil magnet, put a piece of strip with a cut plastic bottle (to hold the gap), it should be in the rayon from 0.8 to 1 mm. But again, you need to look so that it does not catch the sensor. If even with a 1mm gap there is a shorting, then we change the bearings or the rotor itself (maybe a curve).Further, if the candle is constantly wet, this says that the carburetor shimmers! It is not advisable to climb into it (without knowledge). Everything is very fragile there and you can finally break firewood. It is better to replace with a new.

Do not start, grasps: often air leaks! We look at the intake pipe, he has it, almost from plastic! He is spinning over time, he cracks. Also pay attention to the integrity of the gasket, filter and the container itself, the case (there may be cracks).But the most common cause is the wear of the seals! It is not difficult to check: there will always be oil leak or finally everything in oil as in the photo above! You can check (whoever has a compressor) shut up the intake \ graduation channels to pass by spraying the seals with a soap solution and supply compressed air to the crankcase.You can change the oil seals without disassembling the housing, just lift the old special-hard-hardened or stiff bent wire.Do not score a new one, do not shove a screwdriver, or God forbid the sledgehammer. Having smeared the outer edge with a sealant with a slight effort, he must go. If we are tightly selected by the appropriate mandrel and with light blows in the area of ​​the metal clip, we sit in the place.Well, since they removed it, it is advisable to check the backlash of the bearings.If you removed the crankshaft, it is also not cost.effective to change the bearings on it! Better to change everything assembly! And save your nerves and a mower)))).If the mower is weakly drawn (does not have a power), it is advisable to look into the piston. To remove the piston, you need a specification (long hexagonal screwdrivers).Look like that’s it. Who does not know what, we will not be shy.In the course of disassembly, a flaw was revealed, namely a broken oil seal (punched through).The seals were replaced. Installed on additional sealant (window, very expensive and reliable). All gaskets are replaced.All threaded joints “sat down” on anaerobic sealant (Loquetay is popularly) blue.Everything was adjusted and wound up.And people already wanted to throw out))).Do not lose hope))).Good luck and good.
