A trimmer is not started for Sturm grass what to do. The trimmer for the grass is very hot

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.

Где в Сибири Раки зимуют!?! Уловом был сильно удивлён. Ходовая охота на зайцев, тропление зайцев.

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.
trimmer, started, grass, very

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.

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?

I bought a new lawn mower Occurrest 4200. The engine does not start. What to do?On the service were able to run for a minute. Compression 8ATM. What could be the reason?

The braid for the grass does not start the proton MI 2500: it was a little smashed, drowned, then started again, it stalled and did not start anymore. I cleaned the candle from the haze, but it did not help, the candle constantly floods

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.

Car CAMPING in Rain by beach with tent

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

The PROMO RVS-43 trimmer does not start and the candle is dry, and gasoline enters the carburetor.Please tell me what the reason can be ? Thanks !

Help! The mower starts up but does not gain momentum

Good afternoon floods the candle drying it, it starts to get a knife on the gas stalls a trimmer for the grass new champion tell me what are the problems

In the trimmer Shtil FS 55, after replacing the ignition coil, oil seals and piston rings, does not start.What could be the reason

TEXAS trimer, there is a new piston, gasoline acts, it worked as a staller cooled a candle, I got a stupid changed the zero, you try to grab a dry candle, but it can’t get wet, as soon as the candle is weeping all sparks, that you advise you, that you advise.

After warming up the engine loses power and revolutions, what and what to do?

The lawn mower starts on the leak and when you turn off the leggbaking braid for grass stalls) help

Most likely problems with the carburetor. Engine defect needs.

Hello, a Chinese lawn mower is not started. Replaced the carburetor, piston, magneto. There is no effect. On the old piston were bulletin. What could be the reason.

The Carver GBC 31FS lawn mower is not started, and if you started, it does not work at low speeds (idle).What to do?

Good afternoon. The lawn mower recently began to start for a very long time when the accelerator is turned on, you need to pull the cord for a very long time, after which everything starts and works well, starting hot from the second third time, but during operation it splates the entire body of the motor felts, felts with working out or gasoline, I do not understand, help advice.

A motorcycle braid for Iron Angel BC 25 is not started that could be? Carbon new was working in a couple of days I did not want to start up

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.

Benzotrimmer malfunctions and ways to eliminate them

Benzotrimmer. non.secretion of their elimination.

Benzotrimmer. malfunctions and their elimination.

The gasoline trimmer for the grass is extensive distribution due to the low price and ease of operation. It is needed to care for the sites and among the summer residents and the owners of personal houses. Because this tool is used exclusively in the warm season, before operation, the tool must be checked and prepared. grease the rubbing parts, pour the fuel mixture, put the cutting headset.

In the work of at least some kind of technique, failures and malfunctions happen in order to eliminate them without the help of others, you need to understand the device of your unit and the principle of its work. To do this, first, it is necessary to study the annotation of the operation, which the merchant in an ineffective manner applies to equipment when selling.

The iron tubular bar is attached to the gearbox of a two.stroke gasoline engine. Snutsi the bar passes the shaft, which transfers the torque from the gasoline engine to the cutting mechanism. Cutting headset can spin at a speed of 10,000 to 13000 rpm.

The most common repairs of the trimmer for grass and the malfunction of the benzos, the reasons for their occurrence and methods of elimination (in the form of questions and answers) are described. The gearbox body should have holes through which lubrication is made. For ease of use of trimmers for grass, equipped with a belt and a shoulder belt.

The mowing occurs specifically by the cutting set, which is placed in the trimmer head, it is most and is subjected to wear. To change the fishing line for a trimmer, you need to either wind the latest on the bobbin, or install another coil with an already wound fishing line. A handle on which control levers are placed to the rod. The cutting mechanism is protected by a special casing.

Two.stroke lawn mowers are seasoned with a consistency of gasoline and oil, which is poured into a fuel tank. In four.stroke. gasoline is poured into the tank, and the crankcase oil.

The engine does not start. If your benzotrimer does not want to start in any way, first check the presence of fuel and its quality. Low quality of gasoline can lead to the failure of the piston group. Then expensive repairs are guaranteed for you.

The main malfunctions of the microwave and ways to eliminate them. It is fundamentally also correctly preparing the fuel mixture. The proportions of gasoline and oil are always indicated in the leadership.

The mixture should be fresh, because during storage it loses its characteristics.

The whole premise that the braid for the grass did not start is pollution of the fuel filter. In this case, you need to check the condition of the filter and, if necessary, change it. It is forbidden to operate a tool without a fuel filter. If the engine is junk, it is also worth checking the Ivovodniy filter.

When contaminating, the part is removed, washed in gasoline and put in place. If this is not possible, you can rinse in water with a detergent, dry, moisten with oil, squeeze and install in place.

If all of the above is already tried, but the engine still does not start, then try to adjust its speed at idle, twisting the carburetor screw.

Checking the ignition coil without a motor (Lifan190FD)

It is realistic to do this at home, and understand whether the acquired parameter is located in the operated boundaries, only you need to navigate in the norms of your unit directly, which you will read about in the annotation, in addition in our necessary articles. often the performance of the ignition coil is checked by the oscilloscope, it must also be connected to the wires of the reel winding, and as a result we will get the number of characteristics of its condition. For users, remember the working condition of the coil, because it affects not so much on the start of the current operation of the machine, but at the same time entirely on the mechanism by and large. Working ignition coil, like a fishing line for a trimmer for a trimmer for grass. this is a fundamental component of the entire complex of the device.

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.

First of all. check the presence and quality of fuel

Do not understand why the lawn mower is not started, then initially make sure that there is a fuel in the tank. Often, beginners forget that it is necessary to periodically make pauses to season the tool with a gasoline mixture. If the gas mushroom tank is empty, then of course it will not start, no matter how much you try to do it.

If there is a fuel in the tank, but it is impossible to start the tool engine, then do not rush to disassemble the carburetor. Make sure that the trimmer engine is launched correctly, as indicated in the instructions. If the launch is carried out according to the instructions, then it is important to consider the following points:

  • Use not just high.quality gasoline with the maximum octane number, namely the brand recommended by the manufacturer. And far from always such a brand is AI-95 gasoline. If you do not know which gasoline is used for the lawn mower, then choose AI-92
  • The oil should be special. for two.stroke engines. If the lawn mower has a four.stroke engine, then pure gasoline must be poured into it without stirring with butter. On the quality of the oil for the engine engine, the grass should not be saved, as well as on gasoline. After all, the operational resource of the motor depends on the quality of the fuel used
  • Proper preparation of the fuel mixture in a benzotrimer. Observations show that most mowers are only the first time control the process of cooking oil with gasoline for a trimmer for grass. The greater the experience of Kosar, the less close attention is paid to the process of mixing gasoline with butter for a two.stroke engine. The ratio of gasoline with oil should be the way the manufacturer recommends. Typically, this ratio is 25 to 1, that is, 1 liter of gasoline needs 40 ml of two.stroke oil (motor oil for the car and even more so you cannot use it)
  • Proper storage of fuel mixture. It often happens that after the preparation of the fuel mixture, it costs for a long time for more than 2 weeks. It is impossible to store the finished mixture of gasoline with oil for a long time, as this leads to the fact that the oil is precipitated, and thereby the properties of both oil products are lost. Even thoroughly stirring after prolonged storage of the finished mixture is not a reason for its further use. That is why it is not recommended to prepare more than 2 liters of the mixture at a time

Make sure that all of the above points are made, and only after that you can start checking the condition of the candle. A trimmer for grass is not started for various reasons, and most of them can be identified independently. Resorting to disassembling the carburetor, if it is impossible to start the engine, is simply irrational. The next step towards finding a malfunction is a check of the state of the spark plug.

The lawn mower is not started? Eliminate the most common reason

Chinese motorcycles headache for the owner, but still without them nowhere. The main problem is the difficulty of starting after a long downtime. If the lawn mower worked as a clock in the fall, but it does not start in the spring, then you must most likely disassemble the carburetor and clean its valve.

Necessary tools:

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.

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.

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.

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 everything is in order with electrical equipment, then we check the carburetor.

Vacuum carburetors are put on trimmers for grass. When disassembling it, cleaning or washing, you need to be extremely careful. in no case do not disassemble the lower part of the carburetor where the primer is located. Air filter (it is visible if you remove the protective casing from the carburetor) should be washed with detergents. Best. for washing dishes. After drying, we put it back. Rinse the carburetor with clean gasoline and blow out all the holes by the pump. We also wash the filter of the gas pipeline, then we dry everything and collect everything. Usually, after all manipulations, the trimmer for the grass begins to work.

Thin cable instead of fishing line, whether it is worth placing it on a motorcycle?

This thought comes to mind almost everyone who had to pump out 10 acres overgrown with high grass. At first glance, the idea seems good. The cable is stronger than the fishing line, not so wear out. However, not all so simple.

If you put a cable instead of a fishing line, without the possibility of its release, reliably fixing the two ends of the cable and cutting them with welding (a drop of melted metal holds the cable from blooming). Grass such a tool “falls” at a time. The shoot is cut off about a finger with a thickness. Stones are not as afraid as disk. There is true, the problem: when wear, pieces of cable threads break off, and these twisted wires remain in the place of mowing. If you step on them, you can get hurt.

But pieces of the cable remaining on the field are half a bastard. The fishing line for the trimmer, breaking off, weakens the dynamic blows to the transmission and the engine, the cable does not give such an opportunity. Result of quick wear of motorcycles.

It must also be remembered that a piece of cable, promoted by centrifugal force during the rotation of the trimmer head, flies like a bullet. Imagine what will happen if he gets in the leg or someone in the eye?

The use of a cable, wire, a multi.core cable instead of fishing line leads to a quick breakdown of a trimmer for grass. In addition, this is a direct violation of safety precautions!

Experienced users recommend buying a fishing line for a trimmer with a profile “Star”. Compared to round, it mows much better, stems with a thickness of a fishing line for a trimmer with a diameter of 3 mm chopping into a lightweight, and less consumed.
