Why the manual lawn mower does not start the main reasons. Ignition module

The causes of breakdowns of gasoline and electric trimmers

Trammer for grass, both electric and with an internal combustion engine (ICE), is an indispensable tool in the summer and autumn period for owners of cottages and private houses. With its help, weeds, small shrubs are easily removed and the lawn is trimmed. But, like any technique, trimmers for grass fail at the most inopportune moment. To eliminate the malfunctions with your own hands, the user of this technique first needs to determine the reason for their appearance.

In the lawn mower and an electric trimmer for grass, if you do not consider breakdowns associated with the bar and the mowing head, the malfunctions mainly happen in the engine area.

Damage of gasoline trimmers

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

• engine breakdown;
• problems with the carburetor;
• problems with the supply of fuel;
• muffler malfunction;
• gearal breakdown;
• The starter broke;
• Air filter problems;
• Broken a buckshot on a gas tank.

Malfunctions of electric trimmers

Since the device of an electric coser is much easier than a motirmer, then there are few reasons for its failure.

It should be noted that the elimination of some of them is best entrusted to the specialist.

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

• Electric cable malfunction;
• The control button is faulty;
• burned engine winding;
• Contact joints break on the engine.

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:

• 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.

Why and what to do if a gasoline trimmer for grass does not start

If a benzotrimmer does not start, the breakdown can be caused by several reasons. Most often, the failure occurs:

• due to clogging of air or fuel filters;
• because of the exhausted old gasoline in the tank;
• due to damage to the fuel hoses;
• due to damage to the ignition system;
• due to a short circuit of the wires responsible for inclusion.

Also, the launch of the primer and the saapon, the clogging of the carburetor and the air damper drive clogged.

The most difficult thing is to repair a benzotrimer with a malfunction of the engine, but such a breakdown is rare

Exhausted gasoline in the tank

Many trimmers left fuel in the tank after using the unit. If the cover is not closed not, gasoline can exhale and absorb moisture from the air. As a result, the combination of the mixture is reduced, and the motor does not start.

It is very simple to fix the situation. you need to remove old fuel from a gasoline trimmer for grass. Do it like this:

• Pump up new gasoline primer.
• Twist the starter cable many times.
• Pump the old fuel through the combustion chamber until the tank is empty.
• Dry the candle.

You can also simply remove and disassemble the carburetor to drain the remnants of exhausted gasoline. But it is more difficult to do this, you must have minimal ideas about the device of a trimmer for grass that does not start.

A short circuit of wires

The wires suitable for the engine are responsible for the engine. they are connected by the switch, and as a result, the gasoline trimmer for the grass is launched. Due to poor-quality isolation or permanent vibrations, the cables can be wiped out.

If a short circuit occurs, the engine is not started by pressing the button. You can eliminate the problem according to this scheme:

• The wire departing from the start button is removed from the terminal terminal of the ignition system.
• Using the tester, check the cable resistance in “Inclusive” and “off” modes.
• If there is a malfunction, a working handle of a gasoline trimmer for grass is disassembled.
• Cut or solder suitable to the motor, ignition system and wire button.
• Extract the remains of cables and set new in their place.
• Collect the hilt back.

If the gasoline trimmer for the grass starts again, the repair was successful.

Attention! In good wiring during testing in “inclusive” mode should give resistance striving for infinity.

Flowing the air filter

If the trimmer for the grass has not stalled and does not start, the problem may consist in clogging an air filter. To diagnose a breakdown, you need to extract a candle from the unit case and inspect it. If there is clogging, it will be black.

To eliminate the problem, you need to disassemble the motorcycle and pull out the filter from the body. It is cleaned in accordance with the instructions for a specific trimmer for grass, and then set to place. To prevent the problem, it is recommended to conduct preventive maintenance of equipment from time to time.

Falf in the spark plug

If the benzotrimer does not start, the failure can be caused by a candle breakdown. Diagnosis is carried out as follows:

• Twist the element from the cylinder block head.
• Carefully examine. if the contacts of the candle will be covered with a malfunction, will be covered with a black coating.
• Soak the part in vinegar solution 20% for half an hour to clean.
• Sprinkled with soda and washed with water after another 30 minutes.
• Dry with compressed air and installed in place.

In some cases, after cleaning, the candle comes into an efficient state, and the gasoline trimmer for the grass starts again. If this does not happen, you need to replace the element with a new.

If a black fog quickly appears on the new candle, the problem may consist in re.enriched fuel

The ignition coil malfunction

If the trimmer for the grass is jerking off and does not start, it is worth checking the ignition coil. Do this as follows:

• All wires turn off the block and remove them from the candle.
• Measure the resistance of both coils-in the primary it should be 2-3 Ohms, in the secondary 4.5-5.5 ohms.
• With a strong deviation of the indicators, the ignition unit is replaced with a new.

You can check the knot in another way. Instead of a candle, the tip of the discharge is inserted into the appropriate wire and the latter is connected to the motor. Then you need to set a gap with a size of 0.5-0.8 mm and twitch the starter cable. The ignition unit requires replacement in the absence of a spark, but if it is, then the malfunction lies in the candle.

Recommendations and preventive measures

It is quite difficult to start a benzotrimer with malfunctions, sometimes repair requires a lot of costs and applies of efforts. Avoid breakdowns allows compliance with prevention rules. In particular, it is recommended:

• Timely clean the ribs of the starter and channels on the housing of a gasoline trimmer for the grass;
• Before a break in the operation of the unit, drain the remaining fuel from it;
• After cleaning the gas tank, start the engine at idle to eliminate the last traces of the mixture;
• use only high.quality fuel when operating the unit;
• load a gasoline braid in accordance with the instructions;
• Before cleaning for storage, disassemble and thoroughly rinse the trimmer for grass with solvents.

It is recommended from time to time to subject the gasoline braid to be careful to identify mechanical defects. Regular preventive cleaning requires air and fuel filters of the system.

Attention! Before cleaning the gasoline trimmer for storage grass, you need to lubricate the piston group with motor oil.

The more intensively the benzotrimmer is used, the more often its individual working nodes clog

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 oil additive 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 oil:

• 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.

Cycle: why the piston may not move inside the cylinder

The flywheel of a trimmer for grass, aka Magneto’s rotor with magnets, is fixed on the shaft with a key.

This is usually a reliable connection. Under the flywheel there is a sealing oil seal that does not pass the oil from the crankcase out. But when he wears out, the craftsmen have to remove the flywheel and change the oil seal with a new.

Otherwise, the oil flies everything, including the air filter.

At the same time, it is not so easy to remove the key: people make special pullers.

When looking for information on trimmers, I came across a video of one master, who was brought into the repair of the lawn mower, where the flywheel gap was absent. Perhaps a factory marriage. Naturally, such a motor will not start.

A similar reason should also be borne in mind.

Proper care for the chainsaw

There are no unnecessary phrases in the operating instructions, everything that is proposed is aimed at the trouble.free operation of the lawn mower. Cleaning all parts after each cycle of work contributes to the light removal of not hardened residues and dirt. You need to clean only cooled nodes. This technique contributes to the quality of the air cooling of the engine and the gearbox.

For refueling, it is necessary to use fuel with oil recommended in the instructions. If you leave the combustible mixture in the fuel tank, the oil will float and dies on the damper when starting, worsening its adjustment. The mixture can give a sediment and score fuel supply in the carburetor.

When preserving equipment for the winter, make an audit, grease the gearbox and the piston system, wrap the entire saw in the oiled rags and store in a dry place.

It is impossible, dangerous for the instrument and health of the mowing, use a metal cable instead of fishing line. It cuts more efficiently, but the load on the gearbox and the engine increases. A demolished piece of wire when separating flies at the speed of a bullet. Effective mowing can lead to a speedy wear of the piston group of the engine. For greater efficiency of the mowing, it is proposed to use the profile of the “Star” fishing line.

The candle has a black terry fog, after cleaning it starts and immediately stalls, the candle is flooded.

My problem is that the Hyter lawn mower starts only if I remove the muffler. At the same time, the muffler is clean and I still blew it and cleared it, it is worth putting the muffler in place, the lawn mower will not start, what is with it? Thanks a lot in advance.

How to disassemble a carburetor and which valve to clean

If the motor motorcycles refuses to start, then first of all you need to check the candle. If it is completely dry, then this means that the fuel is not supplied to the combustion chamber and the reason is in the carburetor. Immediately it is worth checking the candle and for the subject of a spark in order to exclude it from the reasons on all fronts.

You can also make sure that the motor itself is serviceable. To do this, having twisted the candle, you need to pour a syringe into a combustion chamber of several milliliters of gasoline. After this, the candle is twisted and the lawn mower is started. If everything is in order with the motor, then it will work for a few seconds. This will once again confirm that it makes sense to disassemble the carburetor.

Next, a plastic protective cover is removed along with an air filter. After that, 2 screws are twisted with a cross.shaped screwdriver, holding the air damper and the carburetor on the engine. Fuel tubes immediately break down.

The carburetor is removed and turned over.

From the side of the cap of the suction, you need to twist 4 screws with a screwdriver, and divide it into 2 halves. We are interested in half with suction. There is a valve from its inside in the center.

He often sticks out, because after evaporation of gasoline, with a simple on it, a viscous oil works as glue. To check it, you need to put a short thin tube and try to blow the air through it. If he is stuck, he will not be able to blow out in any direction.

Caliping of the valve is eliminated by a conventional match. Toothpicks are better not to use, since they are sharp and can harm. A match must be slightly rested on the valve and stir it. After cleaning the match, it will be blown up.

By removing the curtain, you can assemble the carburetor back and install it on a motorcycle.

Fuel will be able to act, so it will work. Cleaning the valve is not a panacea for all motorcycles that do not start after downtime, but this helps in 8 cases out of 10. The remaining 20%, as a rule, are also associated with a carburetor, usually with a needle.

All the whole, clean, works?

We try to adjust. We take a long screwdriver, we find a bolt of idle speed adjustments (it is on the throttle), twist it a couple of revolutions so that the damper is opened. We start. It works smoothly? Then we go further. Does not start or stall? Open the damper until it starts stably.

If the adjustment of the carburetor has not given its fruits, then it needs to be disassembled. Watch the membrane, clean nozzles and inner moves. For this, it is necessary not only to have a reptile, but also preferably a reserve carburetor.

Next, adjust the quality of the mixture with a screw l. You need to achieve maximum storage speeds. Here the principle is the opposite. the more the bolt is unscrewed, the richer the mixture. After that, the quality of the mixture at maximum revolutions by the screw h.

Reasons why a new trimmer is not started for grass

Difficulties with the launch do not only have the types of motorcycle, but also in completely new. In this situation, there is only one way out. to listen to the advice of our experts and take advantage of their practical experience!

The reasons why the new gasoline trimmer for grass does not start is eliminated by the instructions for the plant of the Motokos from the forum users, which sounds like this:

• Turn on the ignition.
• Switch fuel with a silicone button (primer) located below the carburetor. Presses must be done as much (or a little more) as it is written in the instructions, usually about 8-10.
• Close the air damper.
• Fix the gas lever with a button at high speeds.
• Twer the label handle 2-3 times. The engine must “grasp”.

If the engine “grasped” and stalled, then you need to transfer the air damper to 1/2 and try to start the motor again. If the motor has started, then drop the gas and transfer the air damper to the “open” position. The trimmer for the grass is easily launched. We start work.

Performing manipulations for pumping fuel, no need to be afraid to shift it. If this happened, and “flooded the candle”, then it is not necessary to unscrew it, it is enough to transfer the air damper to the “open” position and, holding the full gas, simultaneously scroll through the engine with a starter 2-4 times. After that, you can start the engine and proceed to the mocking of the grass, not afraid that it will stall.

The continuous operation time of the lawn mower is indicated in the instructions for the operation of a trimmer for grass. On average, kosim for 15-20 minutes, after which you need to drown out a trimmer for the grass and let it cool for 3-5 minutes. Also on the duration of continuous work, the weather and operating conditions have a significant impact. In the heat, when mowing high grass, thickets of weeds, under a large load, the trimmer for the grass overheats faster, does not work and hardly starts after the break.

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.

Why is the ignition adjustment

In some cases, when the engine does not start, the ignition adjustment will be required. Of course, first you need to check the serviceability of a candle and a high.voltage cable with a cap.

It is necessary to adjust the ignition on a two.stroke engine in order to ensure timely ignition of fuel in the engine combustion chamber. Below is a scheme from which you can understand the principle of operation of the internal combustion engine.

The spark in the candle should appear at the time of compression of the fuel with a piston, when it does not reach the upper dead point (VMT) at least a little. Когда поршень проходит ВМТ, происходит возгорание топливной смеси, в результате чего поршень под действием энергии взрыва уходит вниз.

Therefore, if for some reason (mainly this is due to the shift of the flywheel to the shaft relative to its original position), the fuel fire occurs earlier than the piston passes, then it returns back, and the crankshaft scrolls in the opposite direction. Such a movement can damage the starter knot, cut off the launch cord, etc.D. In this case, Early fuel ignition

It can also be Later ignition

On the trimmer: the piston after compression of the fuel, which does not ignite, goes down, and at that moment a spark appears. In this case, the engine will either not start or significantly lose power and will be poorly gaining momentum.

But such problems with early or late ignition on two.stroke ICE are quite rare, since the flywheel with magnets is already established in the correct position, which is perfectly synchronized with the movement of the piston. In addition, the flywheel is fixed on the shaft using a key and nut. Therefore, the wrong installation of the part is excluded.

Basically, the ignition adjustment is to set the correct clearance between Magneto and the flywheel.

A Chinese lawn mower is not started.It is interesting.

Spare parts for Chinese motorcycle do not start Chinese

In the case when there is no spark on the trimmer, how to solve the problem you will be told by professionals for a hundred.

Sometimes, the problem can be with magneto. Magneto may become unusable due to the fact that you could pull the starter cord at the moment when the ignition was turned off, and the candle was not grounded for the mass.

Such actions can easily disable magneto. In such a situation, the only way out is to buy a new magneto.

Why not start a chainsaw. the causes and methods of elimination

Each model has its own weaknesses. Some saws require regular carburetor configuration. The lack of others is the lubrication system of the chain. Be that as it may, any breakdown can be eliminated with your own hands if you understand what its reason is, and what are its signs.

What to do if the chainsaw stalls when you press the gas?

As a rule, with this breakdown, the owners of the chainsaws begin to face after the first 6 months of intensive operation of the tool. There may be several reasons for this malfunction.

• the use of the fuel mixture prepared in the wrong proportion. If you regularly pour low.quality gasoline into the tank, in which there is too much or little oil, then the tool will not start. In this case, you will need to drain the fuel, as well as dry the engine cylinder. To do this, you need to sharply pull the starter cable abruptly. After that, it is necessary to pour properly prepared fuel, and start the saw engine;
• Pouring the sparkling candle with oil at the time of engine start. This problem can be solved by removing, cleaning and drying the candle. After 30 minutes, the candle will dry and it can be screwed. After that, you need to start a chainsaw;
• Lack of sparks. This indicates poor contact between the factory high.voltage wire and the candle tip. If the contact is not violated, but there are still no sparks, then you need to check the electronic unit of the ignition system of the chainsaw. This element cannot be repaired, so it will need to be completely replaced;
• Flowing the air filter. This saw element must be regularly cleaned from garbage, small insects and dust. Otherwise, the air will not enter the carburetor, where it should enrich the fuel mixture. As a result of this, the saw will stop starting. To solve the problem, you need to clean the filter, or replace it.

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.

Replacement Lubrication of a hard shaft It happens 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.

Смазка гибкого вала выполняется следующим образом:

• открутите и снимите косильную головку;
• извлеките штангу из электродвигателя, открутив пару болтов;
• вытащите гибкий трос из штанги;
• смажьте тросик смазкой по всей длине.

Делается это так: сначала необходимо смазать конец тросика, а затем вставить его в штангу, после чего, по мере продвижения его внутрь трубы, следует наносить смазку на деталь и равномерно распределять ее по поверхности. Затем вставьте штангу с гибким валом в электрический двигатель и закрепите ее.
