Why is a trimmer not starting for grass gasoline? Reasons and their elimination

Agree that almost any problems with the trimmer can be solved independently without resorting to the help of specialists. Когда не заводится газонокосилка, причины и способы устранения неисправности лежат на самой поверхности. You only need to carry out a thorough diagnosis of the device and determine the key causes of problems.

In this article, we will consider the popular causes of breakdowns of benzocose, ways to detect them. Here is a repair recommendations at home. To simplify the understanding of the process by beginners in this matter, we will provide material for visual photos and detailed video instructions.

Checking the fuel mixture

Suppose you don’t start a trimmer for grass. In this case, the first thing is to check whether the fuel is enough in the tank, as well as evaluate the quality of the fuel mixture. To refuel a motorized unit, it is necessary exclusively high.quality gasoline. It is recommended to use fuel, the brand of which is not lower than AI-95. Refueling a trimmer for grass with fuel of unknown origin, not bought at a gas station, is fraught with frequent failures in the work of the tool. This can cause a breakdown of the cylinder-piston system. Repair in this case often exceeds the cost of the device itself.

Why is a trimmer not starting for grass gasoline? Incorrect preparation of the fuel mixture may also lead to this, which consists of oil and gasoline. The proportions in which the specified components are connected are indicated by manufacturers in the guide for the operation of a trimmer for grass. Preparing the fuel mixture is extremely not recommended in large volumes, that is, for the future. Indeed, with prolonged savings, there is a loss of the determining properties of the substance. Therefore, if a trimmer for grass does not start, it is worth draining the old fuel and use freshly prepared fuel mixture.

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.

What Happens If You Flip A Lawn Mower Over Wrong? (LOSE MONEY)

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.

chinese, lawn, mower, does, start, spark

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.

Rules for the operation and storage of a lawn mower

In order for the lawn mower to start well and continue to provide it with good storage and operation conditions:

  • During operation, carefully monitor the cooling system, carefully and in time, clean the channels in the case, as well as the ribs of the starter;
  • If necessary, use solvents, kerosene and other detergents for cleaning;
  • Do not clean the “hot” tool. let it cool;
  • Stactly comply with the requirements of the instructions for the operating mode, otherwise you can overheat the engine;
  • If you do not plan to use the lawn mower in the next month, the fuel mixture from it needs to be drained, t. to. Over time, it breaks up into heavy fractions, which will definitely clog the channels of the carburetor;
  • After draining the fuel, let the trimmer work at idle until it stalls, this will help to completely remove the rest of the working mixture.

Before winter storage, take the following steps:

  • completely disassemble the braid, rinse and clean all the details you can;
  • Inspect the details for damage, if necessary, eliminate distortions, impulses, bent and any other malfunctions;
  • Pour a sufficient amount of oil into the gearbox and clean the air filter;
  • You can partially disassemble the motor, rinse, blow and smear all the moving parts;
  • In order to lubricate the piston, you need to unscrew the candle, raise the piston with the outlet to the extreme dead point, pour a little oil into the candle hole and scroll the crankshaft a couple of times;
  • If you store the lawn mower not in the house, wrap the engine with an oiled rag.

Everything is like my Hammerflex MTK 31. He started, began to mow, after pumping a plot of 105 meters, a braid for herbs died out. Attempts to start a nickname did not bring anything, cleared the candle, started. Literally a minute later, the braid for the grass was stalled and no longer wound up, even the starter could not pull, it closes in half, it is impossible to pull the cord.

Check the high.voltage wire and tip on the candle. I have a spit for grass “Patriot” (3 liters.With.) turned out to be a tip. just a piece of paper clip (the wire inserted into the wire). I took VP from the old Volga. everything works amazingly.

The braid for the grass did not start, changed a new candle.There is no spark, what to do?

It is necessary to check if there is a spark when leaning the cradle (cap of candle) to the cylinder. If not, call the high.voltage wire for its integrity. If the wire is intact. see the ignition unit.

After winter I tried to start the braid S K.240, and the starter does not twitch. Last time worked normally. Spit year.

Most likely the carburetor settings were lost

Wife flooded in Hammerflex pure gasoline.The trimmer for the grass works for 5 minutes and stalls Then I told her to urgently merge it and diluted it They did everything as it should, but still stalls after 5 minutes until the clean gasoline for the grass did not flush

LEX mower starts up normally, but for some reason it is quickly warming up and does not start on hot, tell me what the problem is?

“Forester 304”. It doesn’t start in any way, last year it was brought up with a kick from the same time, and then I worked a little and jammed, this year it didn’t start at all, they checked the candle, the candle is dry, the thread is slightly wet, the candles were changed, but the candle is, they changed gasoline. did not help, tell me what to do

Hello! I have such a problem, I started a braid, gave gas, it is strangled, I went clear a carburetor for a compressor, but I decided to buy a new one, put a new one, it no longer starts on any carburetor, the candle fits the spark, but for some reason the air filter in Half gasoline was not there before, and no one touched the carburetor, both new and old. What to do?

Another reason for not starting the lawn mower may be a silencer, I, on the advice of his familiar mileage (such a snake Gorynych turned out) and a braid for the grass started!

Do not start a lawn mower. Gasoline is not supplied at all. If you wet the candle, it will hole it once and that’s it. The carburetor was washed in gasoline, blowing. Uselessly.

See if fuel is supplied to the carburetor from the tank.

And how complete your tank is? If under the neck, then fuel is not supplied so will not be created in the tank. The reason can also be a torn membrane in a carburetor. In this case, you are in the service center.

Half a bacon. I tried even with an open lid. The membrane is not torn, it can be stretched In general, I will better take it to the service center. So as not to deliver her fuck

Problems with the carburetor, and the engine is necessary to defect. I read what you write?

Hello. The Stihl FS-55 lawn mower, the spit is 2 years old, but rarely used, the total operating time is no more than 5 hours (I think that less-the site is not large-I roll out in 15 minutes). Last year I worked strained, I had to gnaw so that I would not stall. This year, the plant does not respond to the plant at all. The candle is working-rearranged at the MS-180 saw, and a candle from saw to a braid. I also tried to fill the gasoline directly into the cylinder and start. the braid for the grass starts and stalls. T.e. Gasoline does not act. When you press the primer, the fuel enters it. Crossed the carburetor. it is virgin clean. Pulled out and wiped all the gaskets, filter. I blowed holes. When trying to unscrew the jacket. a little broke (broke) on a slot, but the nozzle itself is normal. He also blew him. In short, he killed all day on a thorough bulkhead (and more than once sorted out), but nothing helped. a braid for grass does not start. I also tried to regulate the carburetor. with the same result. What else can be done? In my opinion, it remains to only disassemble the braid for spare parts, and carefully examine each node. But somehow I really do not want to go there, despite the fact that the braid for the grass is almost zero, despite age.

Elimination of the reasons why the lawn mower is not started

The fuel mixture should be prepared with accurate observance of gasoline and oil proportions. In this case, you cannot use another brand of fuel. To exclude dirt, gasoline should stand in a glass or metal dish 2 days. Cannot be used for storage of fuel plastic dishes. Distribute the oil with a medical syringe without a needle. Use only a freshly prepared mixture, without leaving an unexplored fuel in a tank. If the engine is capricious, the lawn mower stalls, when you press gas, it may be guilty of fuel.

The lawn mower does not start hot. press the gas trigger and pull the cord abruptly several times until the engine earns, then lower the trigger. Not starting. specialized repair is required.

Checking the ignition system, if the lawn mower is not started, is carried out sequentially:

  • Clean the removed candle from soot and dirt, dry, set a gap of 1 mm;
  • Connect to a high.voltage wire and check on a spark, twitching a few times;
  • In the absence of a spark, check the high.voltage wire for integrity;
  • replace the candle;
  • dry the candle channel;
  • At the same time, the operation of the ignition coil is checked, it is faulty if the working candle does not spark.

It is in the case of a malfunction of the ignition coil that the lawn mower does not start hot, stalls, works with interruptions.

Cleaning or replacing the air and fuel filter will provide the necessary consumption of ingredients entering the carburetor. Air filter can be washed in soapy water or replaced. If the nylon canvas is used, it is washed, the porous felt filler is replaced. The fuel filter is changed neatly, not leaving an open suction pipe. Whether the replacement of the air filter is needed, it is possible to determine if the engine with the air purifier removed is launched. Whether it is necessary to change the grid on the fuel supply, if the lawn mower is not started, a dry candle will tell.

Sapun, a hole for air intake into a gas tank. If it is clogged, discharge is created in the tank and the mixture does not enter the carburetor. The hole can be blown with air or cleaned with a needle. Clean the exhaust channel, remove the anti.icper mesh of the muffler.

Carburetor adjustment and configuration

The maximum and minimum engine speeds, even idle is regulated by the carburetor. The stable operation of the lawn mower depends on the amount of fuel mixture and air. The lawn mower is not started with disturbed adjustment of the carburetor. The procedure for setting up the device for supplying fuel at low speeds (L), high speeds (H) and idle (T) is regulated by the same vints:

  • The chainsaw should work for at least 10 minutes, since the adjustment is carried out in hot.
  • The screw n is flooded smoothly to maximum speed, then turning on ¼, counterclockwise, reducing the speed of rotation of the engine shaft.
  • The idle stroke is regulated by the screw T, ensuring that the braid for the grass does not rotate.
  • The screw l is regulated, first opening the throttle as much as possible, and then smoothly reducing the speed to stable minimum.

After adjustment, a proper carburetor with cleaned filters should ensure the operation of the engine. In the event of a malfunction of the carburetor, after its repair, it will again need to configure the supply system before starting the lawn mower.

Rare breakdowns that prevent the operation of the lawn mower can be:

The most important malfunction, the elimination of which is associated with the replacement of the engine may be the failure of the piston group of the engine. The cost of repair will cost about 70% of the cost of the product. To figure out the reasons why the lawn mower is not starting up will help

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.

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.

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.

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.

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 with a small 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 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.

Trimmer does not start for grass. Why?

A gasoline trimmer for grass is an amazingly useful thing, with which you can, without unnecessary troubles, put in order not only a miniature lawn in the backyard of the house, but also to dig a considerable size of the lawn. But, like all things in this world, it has the ability to break. In this article, we will try to figure out what to do in cases where a trimmer for grass refuses to work.

So, what to do if the gasoline trimmer for the grass is poorly started or not started at all? The most common reason for such a breakdown.This is poor.quality fuel. Remember that, for example, trimmers for the grass of brands “STIHL” and “Husqvarna” are unlikely to start the quality below AI-92. Do not save on fuel, t.to. Repair of cylinder parts.the piston group can be a third of the entire cost of a braid for grass, and sometimes even half. Also, when preparing the fuel mixture, it is necessary to correctly observe the proportions of fuel and oil, which are always indicated in the instructions for the trimmer.

What to do if high.quality fuel is flooded in the gas tank, there is a spark, but the tool still refuses to start up? It is necessary to check the condition of the candle. It is located in the center of the gas mowing housing. It needs to be carefully twisted and make sure if there is a raid on it. If it is, then carefully clean the candle from the carbon and dry it.

If the lawn mower does not start even after the methods proposed above, then you need to try to remove the air filter and start the device without it. If the trimmer for the grass has not earned, clean the old filter well from dust or buy a new one.

It also happens that the lawn mower works as a maximum of 5 minutes, and then stalls and does not start until it cools down. In this case, try to open the pouring cover of a benzogornin. a suction sound should appear. After that, tighten the lid back. If you do this manipulation during the time when the trimmer for the grass has just begun to stall, then the turns will recover, and it will be possible to continue to work. If the lawn mower stalled until the cover is opened, then you just need to start it as it should be according to the instructions.

Trimmer for grass does not start after winter

How to be in such a situation? Do not worry and panic. This is a very common problem that is solved in just 3-4 minutes. Firstly, if the fuel is left in the gas tank last year, then it must be drained. Gasoline loses its octave properties after 2 weeks of downtime. Secondly, start a lawn mower after a long stagnation in a slightly different way. First you need to open the damper and pump up a little fuel mixture into the carburetor, then stretch the handle until a small resistance is sensed. After that, you can start a trimmer for the grass.

If, when trying to start a trimmer for the grass, it starts up, but immediately stalls, then the cause of this may be an air filter again. It is necessary to remove it and check if it is clogged with dust. If this is true, then it is necessary to carefully clean it or purchase a new. Also, the problem may also consist of malfunction of the ignition coil. In this case, the lawn mower is best taken to the service center.

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.
