The trimmer starter is spinning hard for the grass

Repair of the starter of a gasoline trimmer for grass may be required at the most inopportune moment. In this case, you can solve the problem in two ways: replace the broken part or change the entire node. The latter option will cost more. To repair the device with your own hands in most cases, you need only a screwdriver with an appropriate tip from the tools. Repair work will not take much time and do not require special knowledge. It is enough to know the device, the principle of operation, the nuances of the assembly-disassembly of the starter on the trimmer in order to achieve the desired positive result.

The gasoline engine is, in principle, the main part of the motorcycles its power lies in the range of 0.5-2.5 liters.With. The movement from it is transmitted by the shaft located inside the hollow bar, and then through the gearbox, consisting of gears, already a fishing line or a knife (working body).

Also, the lawn mower has the following elements:

protective casing;
lever;
a belt designed for ease of use of the device;
Starter serving for launching a gasoline internal combustion engine.

All parts of the motorcycles are presented in the photo further.

The starter on the trimmer is an integral part, which performs the engine starting into operation. It is shown separately in two photos below.

The starter mechanisms of various models of the benzos work according to the same principle: during the launch of the ICE, the protrusions marked in the photograph above the number 1 are included in the hook with dogs 3. When the engine begins to work, they return to their previous position due to the effects of centrifugal. Similar role is also played by wires 2.

The process of returning to the initial position of the elements of the mechanism occurs due to the presence of a spring screwed around the axis. It unfolds when the rope is pulled. After releasing the cord, it is drawn and winding due to folding the spring. During the launch of the ICE of the lawn mower, the triggering mechanism turns its shaft until it starts to work (starts).

To date, gasoline motorcycles are equipped with two types of starter mechanisms:

The first option is much more common.

The starter on the trimmer can function without breakdowns for a long time. It is impossible to unambiguously indicate the deadline. Everything is determined by the initial quality of the device and compliance with the rules of handling it.

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.

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.

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.

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.

Dry and wet candle what it means and how affects the launch of the motor

Most of the owners of the tools immediately resort to checking the state of contacts of the spark plug. This is done in order to understand, by the state of the candle, what could be the reason for the impossibility of starting the engine of the lawn mower. According to the state of the candle contacts, you can draw the appropriate conclusions about what can be the cause of the malfunction. Diagnosis of the spark plug on the trimmer is performed in the following order:

The spark plug unscrews, after which it is subject to inspection. The ideal state of the electrodes. if they have a brown carpet (brick color). If the candle is wet, has a black or white fog, then this indicates the corresponding faults
If the candle is wet, then in the combustion chamber there is a portion of unbroken fuel, which does not need to be drained. Clean and dry the contacts of the spark plugs, then make sure of its serviceability. To do this, connect it to the immunity, and place it not the surface of the cylinder. Turn on the ignition and pull the starter handle easily. In this case, the candle should issue a quality and constant spark. If the spark is weak or it is not at all, then the spark plug should be replaced
A trimmer does not start for grass may not be started due to a large gap between the contacts of the candle. The gap between the electrodes of the spark plug should be in the range from 0.7 to 1 mm. Special probes are used to set the gap

It is interesting! Dry candle contacts by pumping it is strictly contraindicated, since this method will lead to damage to the details.

If there is a spark on the candle, but the trimmer for the grass does not start, then the reason is the supply of the fuel mixture in the combustion chamber. To make sure this, you should perform the following actions:

Dial in a cap made of PET bucks or in a syringe of 20 grams of fuel
Pour it into the combustion chamber through the candle hole
Twist the spark plug
Put on a candlestick and start the engine

If the engine of the lawn mower starts after the actions performed, then the cause of the malfunction should be sought directly in the fuel line and carburetor. If the motor does not start even after the actions done, then you need to check the serviceability of the high.voltage wire. The high.voltage wire, like the spark plug, refers to consumables. If there are suspicions of a malfunction of the armor of the trimmer for the grass, then it should be replaced. If, after the actions done, it is not possible to launch the engine of the lawn mower, then the following recommendations must be taken into account:

If there are doubts about the serviceability of the spark plug and high.voltage wire, then it is recommended to immediately replace them
Check the serviceability of sparking, and if there is no spark on the new candle, then the breakdown is associated with the ignition unit. the failure of the coil is out of order
The ignition coil is not repaired, but changes. If the diagnosis really indicates a malfunction of the ignition of the lawn mower, then it is not difficult to replace it with your own hands

If there is a candle on the spark, and at the same time it is dry, and the trimmer for the grass does not want to start, then we move on to check the next node. air and fuel filters.

It is interesting! If the candle electrodes have a red or pink color, then this suggests that the composition of the fuel used contains a large number of additives. You should abandon such fuel by changing a gas station or a brand of gasoline.

If the trimmer for the grass does not start, we check the serviceability of the filters

You will need to resort to checking the air filter, through which the incoming air is cleaned into the carburetor. The clogging of the cleansing element leads to the fact that the air enters in a smaller quantity or its supply to the carburetor is completely stopped. Find out whether the air filter is the reason that the trimmer for the grass is not started is in a simple way:

Remove the air filter and inspect it. The presence of clogging is already a reason to blame this detail in everything
If there are no clogs visually, then you must try to start the motor without a filter. If a trimmer for grass starts without a filter, then it is definitely necessary to replace this part
The air filter can be cleaned with a stream of compressed air, but if it has not changed for a long time, it is advisable to replace it with a new

It should be noted that a trimmer for grass can not start due to a blockage of an air filter, but these are extremely rare cases. Often, air filter clobs affect the stability of the engine, and also contribute to a decrease in performance.

It is interesting! If the chainsaw began without an air filter, then working as a tool without a filter element is contraindicated, since pollution will fall into the cylinder, and thereby the operational resource will decrease.

The real reason why the gasoline trimmer for grass is not started is to clog the fuel filter. This part is located in the tank of the tool, and if the spit is already more than 2 years, then it is time to check the serviceability of the fuel element. If the filter is clogged, then the fuel mixture will not enter the carburetor accordingly, which means that the trimmer will not start the grass.

There are no difficulties with the replacement of the fuel filter, since for this it is enough to extract this part from the tank, and to replace it. If you are going to clean the fuel filter with a compressor, it is recommended to abandon this venture. It is better to buy a new filter for cleaning the fuel of the lawn mower, since clogs will still remain inside the old element. Below the video shows the process of replacing the fuel filter on the Oleo-Mac brand gasoline.

If you are not sure that the reason for the impossibility of launching a trimmer motor for grass is a cleansing element of fuel, then the following actions should be done:

Remove the fuel filter
Run the lawn mower
If she got started, and quickly, then the problem is really in the fuel filter

The filter is clogged through the following reasons:

With prolonged operation of the tool
If low.quality gas or oil is used
With prolonged storage of fuel in the tank of the tool
If you pour fuel into the tank, which was stored for a long time
When dust and small particles get into the tank of the tool. This usually happens during the tooling

It is interesting! If the fuel filter is working, and the lawn mower is not started, then it is worth making sure that the fuel hose is placed in the fuel. After all, there are times when the hose, along with the filter, is simply disconnected from the trunk tube, which leads to the impossibility of starting the engine engine.

Check the fuel supply

In order to check if gasoline enters the cylinder, you need to unscrew the candle and look at its electrodes. If the candle is dry, then petrol

Apparently does not act, but if it is wet, it means acting.

Sometimes it happens that the candle “throws” the fuel during the factory. That is, there seems to be a spark, but for some reason it was not possible to immediately start the engine, and at the same time petrol

I acted during the twitching by the starter, the candle became raw and through the fuel on the electrode the spark no longer breaks through. In this case, the electrodes can simply be wiped.

Useful information for those who do not have a trimmer for grass after winter

Why does a trimmer not start for the grass after wintering ? What are the main reasons for this problem?

Benzotrimmer may not start due to the fact that the fuel remained in the tank last year, which, simply put, was exhausted. Two signs may indicate this: the candle is dry and there is a spark. To eliminate this problem, you just need to replace the fuel.

In addition, a gasoline trimmer for grass after winter starts a little differently. Open the damper and pump up a little gasoline into the carburetor, and then take the handle until you feel some resistance. After that, you can launch.

With a long simple, an air filter can clog. Evidence of it may be the launch of “hot”, after which the trimmer for the grass immediately stalls. Perhaps in the cold season the filter managed to clog with dust. Two options are possible here: first you need to clean it, and if this does not help, then you need to purchase a new filter.

In general, a similar conversation should begin with the fact that after the purchase of a garden benchmain tool it would be better to get to know the instructions attached to it initially. Then many problems could have been avoided. But since this happened a gasoline trimmer for the grass does not start, you need to look for sources of inoperability. And in this article we will consider the main reasons why the trimmer for the grass is not started by the example of the Elitech T750 model, as well as tell the general recommendations for such a tool.

Start with banal! We will figure out how to properly start a gasoline trimmer for grass. Maybe such that the reason lies here.

First you need to bring a red toggle switch on a trimmer bar for grass to position “i”. This means the inclusion of power supply. Then you need to switch the fuel supply lever on the carburetor and use the fuel “suction” button (looks like a pipette, is on a carburetor). This is necessary to supply gasoline to the engine. Fuel supply lever to return to its original position. At the end, sharply pull the starter handle on yourself. The trimmer for the grass should earn. Try it several times if the first time does not work. If after such manipulations the situation has not changed and a gasoline trimmer for grass does not start, then it is worth it to inspect it on your own first before you lead to the service center. There are two main reasons why the garden trimmer is not started:

The second reason why the garden tool does not work is the fuel ended. On Elinech T750, a fuel tank is located near the motor, but on most trimmers it is there. We unscrew the cap from the tank and pour gasoline there (the most optimal version of the AI-92, it is inexpensive and does not clog the carburetor as AI-76). Do not forget to add special oil for engines to the tank, 50 grams on the gas tank is enough, without it the motor will begin to “sneeze” and quickly become unusable. After cover the tank with a cap, wipe the surface of a trimmer for grass with a dry rag and our hands. We also make the above manipulations to include a garden tool.

If the gasoline trimmer for the grass does not start as before, then it makes sense to give it to repair. And the reason for such a solution is simple. if you do not have appropriate skills, the repair of equipment is practically impossible.

In order for the tool to serve as long as possible and do not arise such malfunctions, you should first get acquainted with the instructions for the operation of a trimmer for grass

Also, pay special attention to the engine time for the grass for the grass. make a short break every 15 minutes of work and, finally, take care of the tool correctly, wipe it after work, lubricate with graphite lubricant. Observing such simple rules, you can significantly increase the life of the tool and it is quite possible that you will not have to look for the reasons why the gasoline trimmer is not started for grass.

petrol? Prerequisites and their elimination

In the near future, a gasoline trimmer for grass

I got the status of the 1st of the main instruments 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 a trimmer for grass does not start hot and even 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 prerequisites, which more often lead to such troubles, will be considered further.

Why is a trimmer not starting for the grass: the main malfunctions and their elimination

As already noted, such situations are characteristic of trimmers who were inactive for a long period of time. Therefore, after detecting the problem, you need to immediately take up the search for a malfunction.

Fuel as source of problems

The first stage is checking the presence of fuel and its quality. First of all, they are convinced that there is a fuel in the tank. Those who have acquired the unit recently, often forget that the trimmer for the grass needs refueling. If there is no fuel, then the equipment simply cannot work.

If there is a fuel in the tank, but the trimmer does not start for the grass, then the owner needs to check whether he is acting correctly. In this case, it is recommended to study the instructions. If the launch is made correctly, then the malfunction can cause the inappropriate quality of the mixture.

Oil. It should be special. intended for two.stroke engines. It is not recommended to save on the product, since the life of the equipment depends on the mixture. Trammers for grass with a four.stroke engine require pure gasoline, it is not mixed with butter.
It is necessary to use not only high.quality gasoline, but also the brand that is recommended by the manufacturer of a particular model. If it is not possible to find out what fuel is necessary, then it is recommended to choose either AI-95 or AI-92, and the last gasoline is a favorite, since the first has additives that react with two-stroke oil. Other brands do not advise using.
The correct preparation is shifted for a benzotrimer. It is noted that at first this stage is paid to maximum attention, but over time, kosari begin to mix the composition “by eye”, and this is already a serious mistake. The correct ratio of gasoline and oil is 25: 1. For a liter of the first, 40 ml of the second, two.stroke. Motor oil intended for a car is an inappropriate option, since at high temperatures the liquid loses (partially) lubricating properties.

The correct storage conditions of the fuel mixture are important. To save time, some owners prepare it for the future to use it in the coming weeks. This option is contraindicated, since the prepared fuel mixture quickly becomes unsuitable. The reason is the precipitation of oil loss. With this change, both oil products lose their properties. Even repeated stirring is not able to restore the initial quality of fuel. Therefore, they recommend preparing a certain volume: 2 liters, no more.

If everything is in order with gasoline and oil, then they start diagnostics. to check the spark plug.

Candle and its condition

At this stage of diagnosis, you need to stop in more detail. Most experienced owners who are already familiar with the question of why a trimmer for grass does not start, first of all check the state of contact contacts. Diagnosis of this element is carried out as follows:

First, the spark plug is unscrewed, then inspect. If the electrodes are in perfect condition, then they should have a carpet whose color resembles a brick. Wet element, or white, black plaque on contacts indicates the presence of any malfunction. Pink and red electrodes. proof of a large number of additives in fuel. Such a mixture must be replaced.
In the event that the spark plug is wet, this means that the combustion chamber has unbroken fuel. It is left in place. Candle contacts are cleaned, then dried (calcination is prohibited). After this stage, the candle is connected to the nurser.
Then the ignition is turned on, the frontier handle is pulled. When everything is in order with the element, it must issue a constant spark. If it is weak or completely absent, then the verdict is one. you need to replace the spark plug.

There is another reason why a trimmer is not started for grass. This is a big gap that appeared between the contacts of the candle. A distance of 0.7-1 mm is considered normal. To correctly adjust the gap between the electrodes, use special probes.

If there is no such device, then the folk method is used. A razor blade breaks, folds its parts together. Then this “probe” is inserted between the contacts. Ideal. blades that enter tightly.

The problem is in the fuel and the carburetor

If there is a spark, and a trimmer for grass still does not show signs of life, then nuisance can lie in the fuel supply to the combustion chamber. To make sure that this node is to blame, they perform such actions:

They are typed in a syringe or poured into a lid from a plastic bottle of about 20 ml of fuel.
Then, through the candle hole, the fuel is neatly poured into the combustion chamber.
The candle is returned to the place, put on the imminent, the engine is launched.

In the event that the trimmer has started for the grass, the problem may be in the fuel and carburetor. Когда эффекта от проделанных манипуляций нет, диагностику продолжают — проверяют высоковольтный провод. At the slightest suspicion, this consumption element is replaced by a new.

What to do if the engine is a trimmer for grass still refuses to work? In this difficult case, you can follow the following recommendations:

In doubt about the candle and the high.voltage wire, it is better to immediately replace them.
If, when checking the new sparkling candle, it was not possible to achieve a spark, then it is almost possible to say with complete confidence that the ignition unit is faulty. the coil came out of the system.

Check its serviceability simply: they twist the candle, then it is led to the trimmer body for grass. If there is no spark when the starter jerks, or it does not appear every time, then a new coil is required. This element can also be replaced independently.

How to avoid most problems?

The work of this seasonal equipment is very affected by its proper storage. over, this applies not only to a long “rest” in the winter, but also of short intervals of inaction. To protect yourself and the technique from problems, you need to adhere to a few simple recommendations.

Before sending on a well.deserved rest, a tank trimmer for grass is freed from fuel remnants. To remove the entire mixture, the lawn mower is launched and allowed to work until the engine is stalled.
The first operation after “winter hibernation”. pouring a small amount of oil into the candle hole. Before that, the piston is moved to the extreme position. Such a lubricant will facilitate the launch and prevent premature wear of the details.

Before starting working with a motorcycle, they must check the candle and all the main equipment components.

Reasons why the trimmer for grass does not start is quite a lot. But most of them can be detected and fixed independently. The main thing is the correct diagnosis, attentiveness and sequence of actions. And about how you can cope with problems, the master from the next will tell in detail

Why is the gasoline trimmer not starting for the grass

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

Fuel tank (fuel quality)

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

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

Candle and candle channel

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

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

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

I LOVE! Milwaukee M18 Battery Powered String Grass Trimmer / Weed Eater 2825 REVIEW

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

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

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

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

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

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

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

Air filter

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

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

Fuel filter

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

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

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

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

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.

How to clean and store a tool?

During the operation of the lawn mower, monitor the state of the engine cooling system. The channels available in the starter housing, as well as the cylinder ribs, should always be clean. If you ignore this requirement and continue to operate the motorcycle, then you can disable the engine due to overheating.

Competent care of gasoline scythe during operation allows you to use it for several seasons in a row without serious repair

Before cleaning, let the engine cool down. Take a brush with a soft pile and clean the outer surface from dirt. Cleaning plastic parts is carried out by solvents, including kerosene, or special detergents.

After the summer season, the lawn mower should be prepared for long.term storage. To do this, the fuel mixture is drained from the tank. Then the engine is launched in order to develop fuel residues in a carburetor. The entire tool is well cleaned of pollution and sent to “hibernation”.

As you can see, it is possible to repair the malfunctions of the household lawn mowed on their own. Service services should be contacted in case of serious breakdowns. In this case, the cost of repairs with the price of a new lawn mower should be correlated. Perhaps it will be more advisable to buy a new tool.

Gear lubrication of a trimmer for grass

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

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

This makes you stand out!

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

Used types of lubrication

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

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

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

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

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

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

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

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

The algorithm for self.lubrication of the gearbox

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

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

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

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

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

The entire reducer lubrication process is demonstrated in the video:

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

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

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

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

The disassembled transmission mechanism is shown in the photo below.

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

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

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

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

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

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

Why does the lawn mower stall after starting?

After starting, the motor may stall if the carburetor is incorrectly configured or it has been resolved. On what signs can be understood that the reason really lies in this? Very simple, by vibrations that will be clearly felt during the work of a gas station. You can adjust the fuel supply with your own hands by completing everything that is written in the instrument operation instructions.

The motor can stall due to clogged fuel valve. The reason is eliminated by cleaning it. If the lawn mower started up, and then stalled sharply, then it is difficult to supply fuel to the carburetor. Weaken the valves of the carburetor to ensure the free approach of the fuel to it in the right amount.

With excessive air leaks, the engine may also stall. Add the engine speed so that air bubbles come out faster from the fuel system of the unit. Be sure to check the integrity of the fuel hose. In case of mechanical damage (cracks, punctures, etc.P.), replace the part.

How to clean and store a tool?

Competent care of gasoline scythe during operation allows you to use it for several seasons in a row without serious repair

To understand this, you need to know the principle of operation of the unit as a whole. It happens so, just purchased, a new saw is not started, and running around the service centers begins, in such cases it is recommended:

The quality of gasoline is poor; improper proportion of gasoline and oil; clogging of the filter of thin cleaning; The spark disappeared.

The lawn mower is not started after winter

In such cases, it is necessary to conduct maintenance of the unit. Remove the fuel system, including filters (air, fuel), disassemble the carburetor, clean each node, rinse. Pour the filters with air. Pay attention to the quality and octane fuel number.

It must be taken into account that the products of such well.known companies as Stihl, Husgvarna and other brands will not work on a cheap octane number of gasoline. For them, suitable fuel from the AI brand. 92 and higher with car gas stations and that, with well.proven ones, since gas stations are also bad gasoline. On the use of highly octane and high.quality gasoline, it will depend on how long the lawn mower will be used and how much it will last.

One more fact must be taken into account that with the long storage of diluted fuel mixture, it falls working qualities, which also leads to the consequences in which the lawn mower will not start. Therefore, it should be diluted with portions, that is, the amount of a mixture that is produced at a time. The operating instructions clearly describe and are given clarifications on the proportion of mixing gasoline and oil. Straighten compliance with the correct proportions will at least save you from several questions, why the lawn mower will not start and what to do in such cases.

The lawn mower starts and stalls. What to do?

There is a spark, and everything seems to be normal, but the lawn mower is not started, in such cases, you should check the air access valve into the fuel tank. Clogging of the valve leads to the creation of a vacuum in a tank, in which the carburetor does not receive gasoline, so the lawn mower will start, but then it will die out. To exclude this reason, you need to clean the valve and try to get a lawn mower with a not fully twisted tank traffic jam. 2. If at the same time the lawn mower is not started, you should remove and clean the fuel filter, as well as check all the parts of the carburetor, and then try to start. The lawn mower is not started again, the air filter is disconnected, try to get without it if the gas station has started to mean the reason in the air filter, replace it.

The lawn mower is not started, the spark is gone

The loss of the spark entails a check of contacts and the correctness of the clearance between them, conducting the wire to the candle and the candle itself. A method of checking the spark. to unscrew the candle, connect the wire to it, attach the candle sideways to the casing of the engine and pull the lawn.mower as if starting the starter several times, while you need to look at the corner and contact of the candle, the spark should run between them. If there is no sparks, take a new candle to do the same procedure, if the spark is not traced, the problem in the wire or contacts means it, it is better to replace them.

The lawn mower is not started on a cold

When starting a cold motor, it is not recommended to press the gas. Having tilted the lawn mower so that the air filter is on top, click on the fuel suction button 5-6 times, install the function of switching functions to the Start position, pull the starter’s cord several times until the motor starts up. After a few seconds of the engine, turn off the start system.

The lawn mower is not started on hot

If the lawn mower was recently at work and did not have time to cool down but did not want to start. press the gas trigger, sharply pull the starter’s cord several times until the engine is started and only then the gas trigger is released. If a lot of time has passed and the lawn mower managed to cool, then it must be started as with cold. If the above methods did not help, the lawn mower did not start, then you should contact the service center.
