About the manufacturer

The history of this German brand begins in 1926. At the initial steps of its own development, the company was engaged in the production and sale of various devices for washing and steam engines. It all began, like many companies, with small production and a narrow focus, which made it possible to focus on the quality of the products.

In the early 30s, the first STIHL chainsaw was released, which was distinguished by its convenience and functionality in those days. The company is developing at a rapid pace, constantly introducing new tools, which gives it the opportunity to enter the international market. lawn mowers Stihl And already in 1931 the first permanent supply of products to Russia was organized.

Device Stihl

At the moment, the company has launched its activities in more than 160 countries, opening new centers and production offices in Switzerland, China and many other countries. This is fully explainable, because the company’s assortment is impressive: motor drills, gas sprayers, mowers, gas trimmers, chainsaws and almost everything else. I would like to note that Shtil chainsaws are very popular due to their own functionality and applicable cost.

When purchasing a lawn mower, you must be prepared for the fact that, like in all other similar tools, breakdowns may also appear in it, which will require repair.

But you should not immediately run to the service center and pay large sums to the craftsmen, convincing you of a severe malfunction in the device.

lawn mowing stalls at high revs on gas

Perhaps the more common complaint related to gas trimmers is: “lawn mowing stalls. “

Naturally, a rather severe malfunction can also be a prerequisite for this. The two-stroke trimmer engine does not develop revolutions stalls. lawn mowing fs 130 give the gas stalls. But in most cases the situation is even simpler than it seems at first glance.

To cope with such a problem, first, try to understand its causes without the help of others, because after finding out the reason, it is even easier to fight the problem, and from time to time it will even self-destruct.

Vibrations that occur during the operation of lawn mowers can lead to misregistration.

Incorrect adjustment of the lawn mowers can be corrected by simply adjusting it in accordance with the requirements specified in the instruction manual.

In addition, sometimes gasoline trimmers can stall due to the valve located in the gas tank cap simply clogging or sticking.

To find out, try using a scythe by loosening the gas tank cap.

If the device works properly in this mode, clean the valve.

Features and best models

The Stihl mower deserves special mention, which is distinguished by its own multifunctionality, reliability and ease of operation. Specialists of the company created many varieties of braids, with different features and applications.

For instance, The range of lawn mowers is designed for mowing grass in large spaces.. For this, a self-propelled wheel system was developed, with which it became possible to care for a large territory without spending a lot of time and effort on it.

Some tricks of working with a petrol trimmer

The summer season has come, and lawn mowers have habitually rattled out on personal plots. Great tool, powerful and mobile. With the help of a gas trimmer, you can also cut the grass and get rid of dried weeds. However, there are cases that the lawn mowing does not start, works intermittently or without developing full power. There is certainly no time for work! And as they say, you pull the starter handle more than mow.

Difficulties with launching arise not only in experienced lawn mowers, but also in new ones. How to be in this situation? There is only one way out. to heed the advice of experts and take advantage of their practical experience!

FS 38

The model is primarily distinguished by its simplicity and compactness, which is enough for proper care of the adjacent area. The main control keys are located on the handle of the device, which greatly facilitates and speeds up the work.

The price for the Stihl FS 38 is about 130.

  • engine power. 0.9 hp;
  • engine displacement. 27.2 cm3;
  • tank volume. 0.33 l;
  • engine type. two stroke;
  • barbell. straight;
  • handle. D-shaped;
  • equipment. 2-tooth trimmer blade for grass, glasses for protection, belt;
  • weight. 4.1 kg.

Stihl fs 38

This model is one of the most popular on the market! You will find out about all the units that are included in the rating of the best lawn mowers here.

You bought yourself a new gas trimmer and you immediately got into trouble. Very bad start. If you mow a little and then turn it off, then turning it “on hot” is an even bigger problem than “on cold”. What to do with it, I won’t know how to start it right?

The instructions for the lawn mowing plant are as follows:

1. Turn on the ignition.

2. Pump fuel with a silicone button (primer) located at the bottom of the carburetor. It is necessary to do as many clicks (or a little more) as written in the instructions, usually around 8-10.

3. Close the choke.

4. Secure the throttle lever with the stop button at higher speeds.

5. Pull the starter handle 2-3 times. The engine should “grab.”

If the engine “grabbed” and stalled, then you need to turn the choke to position 1/2 and try to start again. If the engine starts, then we dump the gas and put the air damper in the “open” position. Getting started.

Carrying out fuel pumping manipulations, one should not be afraid to overfill it. If this happened, and, as they say, “they filled the candle”, then you do not need to unscrew it, just turn the air damper to the “open” position and, while holding full throttle, simultaneously crank the engine with a 2-4 times starter. After that, you can start the engine and get to work.

FS 70

She is more advanced model, characterized by higher power and multitasking. An anti-vibration system is provided, which can significantly reduce the impact of a running engine on the handle.

The time for continuous operation of the lawn mowers is indicated in the trimmer instructions. On average, we mow for 15-20 minutes, after which we muffle the trimmer and let it cool for 3-5 minutes. Also, the duration of continuous operation is provided by weather conditions. In hot weather, when mowing tall grass, weeds, under heavy load, the trimmer overheats faster.

Many problems with lawn mowing are due to improperly prepared fuel mixture. In two-stroke engines, lubrication is done with special oil (not ordinary motor oil!) Mixed with gasoline. If the oil is not mixed with gasoline, then the lawn mower will quickly fail. Oil / gasoline is mixed in the proportion indicated in the trimmer instructions. This is usually 1:40 or 1:50.

The question often arises: the proportion of 1:50 is how much oil and gasoline?

The numbers mean the following: fifty parts of gasoline are taken per part of the oil. Hence: 1000 ml (1 liter of gasoline) is divided by 50, we get 20 ml, i.e. 1:50.

Thus, the composition of the fuel mixture (gasoline / oil) in any proportions can be calculated. To add oil to gasoline not “by eye”, it is advisable to take a 20 ml medical syringe, draw oil into it and “inject” into the tank to prepare the fuel mixture.

If you have ever purchased a trimmer that works with gasoline, then you probably had to deal with the problem of turning on the trimmer, as well as with such a problem as a gas trimmer does not gain revolutions.

That is why this article was created.

So what to do if the trimmer that has been working for you for several years now suddenly just stops gaining momentum and the motor simply stalls? In this case, you and I should consider a number of problems associated with stopping the motor.

Video: Scythe Trimmer Does Not Develop Turnover

The motor may stall under various circumstances. Why lawn mowing revs. I can’t get it off the ground. And it’s gaining momentum from the floor. Sometimes the cause of incorrect operation of the trimmer running on gas is the clogging of the air filter.

This filter is one of the main reasons why the gas trimmer may stop working.

Different rubbish very often gets into it, dust particles get there, which also clog the filter, so it needs to be cleaned and washed every month, and maybe more often, it all depends on how much power the gas trimmer has, and also how much Often you use this device.

For the period of engine break-in (this is approximately the work of the trimmer on 2-3 tanks), the amount of oil can be increased. For example, mix it with gasoline in a ratio of 30: 1.

A small amount of oil mixed with gasoline leads to increased wear of the piston-cylinder group. An excess of oil in the mixture is not so fatal, but also harmful. Coking of the piston rings, rapid formation of soot in the combustion chamber, and a drop in engine power can occur. In addition, the coke screen of the muffler is coked. Therefore, some users (after the end of the warranty period for the trimmer) recommend dismantling it.

The gasoline used in the lawn mowing machine is AI 92. The brand of gasoline is precisely prescribed in the operating instructions. Do not try to “force” the engine by pouring 95th gasoline into it. This can lead to overheating, unstable operation of the trimmer and breakage.

It is not recommended to leave fuel in the trimmer tank during a long break in work. It is better to finish the working day, having fully worked out the whole mixture. If this is not done, then, because during the night the gas from the engine evaporates, and a thin film of oil remains, the carburetor jets may become clogged. This will cause difficulties the next time you start the engine.

It is also necessary to observe safety precautions when storing fuel. Many pour gasoline into a plastic water bottle. Is it worth it?

FS 130

The model belongs to professional models, so the goals set before it will be slightly higher. It is designed for mowing rough grass, harvesting hard shrubs and young trees.

It provides the latest engine of high power, not emitting a large amount of harmful emissions.

The price for the Stihl FS 130 is about 400.

  • engine power. 1.9 hp;
  • engine displacement. 36.3 cm3;
  • tank volume. 0.53 l;
  • barbell. straight;
  • handle. T-shaped;
  • complete set. shoulder strap, two-blade knife;
  • diameter of fishing line. 2.4 mm;
  • weight. 5.9 kg.

The spread in prices for these models does not mean any difference in quality, first of all, Each Stihl mower is designed for a specific type of work.

It is clear that there is no point in acquiring a more expensive and powerful model if you have a small plot or lawn in front of the house. Simpler models will perfectly cope with this task, but the word “simplicity” is not used in a derogatory form here. powerful mowers are designed to handle large areas with overgrown and thick surfaces, hence the difference in price. If you are confused in such a variety of tools, then do not be upset, but feel free to click here and we will tell you how to choose a lawn mower for a summer residence.

Characteristics of the model in the video.

However, no matter which model you choose, you must follow certain operating rules recommended by the manufacturer in order to avoid possible breakdowns.

lawn mowing not develops momentum.One more cause

Chinese lawn mowing Husqvarna analogue reason does not develop turned out to be very simple (see video)

If you have done the filter operations, but the operation of the gas trimmer has remained the same, the gas trimmer is not gaining momentum, what should I do?

Then you should try to remove the filter from the device in order to provide the so-called “relief” of the trimmer. Why the Chinese lawn mowing does not develop momentum, the reason is Husqvarna. Should help.

The next and quite common problem when working with a gas trimmer is that it simply stalls and does not give any signs of life.

In this case, the problem may be as follows:

The last and most common reason for the breakdown of the gas trimmer is that the cable, which is located in the carburetor section, simply slept.

Therefore, make sure in advance that it is well tensioned, but not to the limit, otherwise if the load on the gas trimmer is too heavy, this small cable may crack and then you will definitely have to contact the service center, and then also throw a lot of money down the drain.

In no case should gasoline be stored in plastic containers from under water. When mixing the fuel mixture, a static charge builds up, you can catch a spark.

Therefore, at gas stations they are not allowed to refuel gasoline in plastic cans, only in metal ones. Before pouring gasoline into a metal canister, it is better to put it on the ground, so the static is removed from the body.

But there are situations when simple manipulations with the lawn mowing do not help. The engine still does not start. In this case, we check the power supply and ignition system, guided by the rule “the engine does not work if there is nothing to burn or nothing to set on fire.”

Recommendations for use

It is necessary to take temporary breaks in work. lawn mowing does not develop speed Diagnostics and trimmer mowing stalls at. This is necessary so that the engine of the device does not overheat and does not fail prematurely. lawn mowing does not develop Dismantling a chainsaw Stihl 180 Stihl FS 55 is not gaining momentum? Yes. For amateur models, a break is provided every 20 minutes for the same time. For professional mowers, interrupt work every 50 minutes, in which case the downtime should be at least 10 minutes.

It is necessary to monitor the condition of the fuel tank. If you do not plan to use the mower for a certain time, it is better to drain the remaining fuel from the tank compartment. This will help prevent damage to engine parts.

Terms of use

Benzotrimmer loves cleanliness. It is necessary to monitor the cleanliness of the air filter and fuel. It is better to stand for gasoline purchased at a gas station for 2 days and pass it through the simplest filter. a piece of bike stuff.

We check the electrical equipment as follows:

1. Unscrew the candle, inspect the gap between the electrodes. We set the correct gap between the electrodes in the “grandfather” way. We take a razor blade, scrap it in half and insert a home-made probe between the electrodes. If the blades fit tightly, then the gap is ideal.

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

Also in electrical equipment, an ignition coil may be punched. In this case, the lawn mowing does not start or starts and works intermittently, and then stalls, or does not start up to the “hot” one at all.

You can check the serviceability of the coil in the same way as when checking the spark: unscrew the candle, lean it against the body of the trimmer. If there is no spark when the starter is jerked, or it appears every other time, the coil must be changed.

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

Vacuum carburetors are placed on trimmers. When disassembling, cleaning or rinsing, you must be extremely careful. in no case do not disassemble the lower part of the carburetor, where the primer is located. The air filter (it is visible if the protective cover is removed from the carburetor) must be washed with detergents. Best for washing dishes. After drying, put back. We wash the carburetor with clean gasoline and purge all the holes with a pump. The gas line filter is also washed, then everything is dried and collected. Usually, after all the manipulations, the trimmer starts to work.

Thin cable instead of fishing line, is it worth it to put on a lawn mower?

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

If you put the cable in place of the fishing line, without the possibility of its release, reliably fixing the two ends of the cable and cutting them off by welding (a drop of molten metal keeps the cable from opening). Such a tool “knocks” the grass at a time. Cutting off the shoot to about a finger thick. Stones are not as afraid as a disc. There is a truth, a problem: pieces of wire rope break off during wear, and these twisted wires remain in place of mowing. If you step on them, you can get hurt.

But the pieces of cable left on the field are half the trouble. The fishing line, breaking off, weakens dynamic impacts on the transmission and engine, the cable does not give such an opportunity. The result is a quick wear of the lawn mowers.

Any braid has a knife on the protective cover that cuts off excess fishing line after winding, and the cable can no longer be cut. If part of the cable breaks off, then the result is an imbalance, increased vibration. Bottom line: the shaft drive bearings are broken.

You also need to remember that a piece of cable unwound by centrifugal force during 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, multi-core cable instead of fishing line leads to a quick breakdown of the trimmer. In addition, this is a direct violation of safety precautions!

Experienced users recommend buying a fishing line with an asterisk profile. Compared with a round one, it mows much better; stems with a finger thickness of a fishing line with a diameter of 3 mm cut into a light, and less is consumed.

Reasons and Repair

I want to share my experience in restoring the required power of a trimmer with a gasoline engine.

One day in early June, I began to notice that my trimmer model GT22GES (manufacturer “ECHO”) began to lose its former power.

In the process of work when mowing grass, even with a slight increase in load (grass is taller and denser), the speed fell and the work efficiency was no longer the same as it was before.

Before the trimmer did not notice such obstacles at all. With a sharp click on the “trigger” without load, the speed increased slowly, as if reluctantly.

I took the user manual for the trimmer, found in it the section “Faults and their elimination.” I chose a suitable fault in the table, which is described something like this: “The engine is not accelerating well or decays.”

Possible causes include contamination of the air filter, fuel filter, clogged fuel tank drainage hole, spark plug, carburetor, clogged cooling system, clogged exhaust channel or muffler.

As it turned out, the list of possible reasons is extensive. where to start?

At first I looked visually at the air filter, drainage hole, air radiator, all this turned out to be in a normal condition.

Then he decided to look from the end of the list, that is, check the exhaust system. the exhaust channel and the muffler.

To do this, removed the spark plug tip, unscrewed 3 screws and removed the plastic muffler protective cover (in the drawing in the Manual under No. 15). Then, unscrewing the two long screws, carefully removed the muffler, so as not to damage the two gaskets that are present there.

Premonition did not deceive me. The exhaust channel of the engine cylinder (through which exhaust gases exit the cylinder) was 30 to 40 percent clogged with soot.

So that was the cause of my trimmer’s frustration!

It looks like the exhaust channel

Carefully, so as not to damage the piston surface and to prevent foreign products (in other words, the very soot) getting into the cylinder, I completely cleaned the exhaust channel of soot, carefully blew the channel with a pump.

I used a knife as a tool (but only at the edge of the canal), and in the depth of the canal I used a wooden and plastic spatula of suitable sizes.

The silencer turned out to be pretty clean both inside and out.

After the assembly, I started the trimmer, warmed it up a bit and tried to mow. the engine worked like new, the power increased noticeably, it didn’t mow the grass, but cut it (3 mm fishing line).

It’s nice that the device began to work perfectly and doubly pleased that he himself was able to find the malfunction and fix it.

It is likely that such a problem can occur in other models of trimmers, because the design for them is approximately the same for all and all trimmers have an exhaust channel and a silencer.

Why do the revs fall on the trimmer

This common problem has a number of different causes. During operation with the device, one may encounter both obvious malfunctions, the signs of which are clearly traceable, and asymptomatic cases. The first option is the simplest from the point of search for the problem. If the trimmer is not gaining momentum and there are no clear signs of damage, then you will need to consistently check the most typical cases of malfunctions, and if a cause is found, eliminate it.

Possible causes of malfunctions in electric braids

When operating the trimmer, on which the electric motor is installed, problems also arise with a set of revolutions. But they are caused by completely different problems, compared to fuel braids. The electric motor does not develop the required rotation speed in such cases:

  • if the voltage acting in the supply network is lower than the rated value for the electric motor by more than 10%;
  • in case of malfunctions in the soft start system (if this unit is installed);
  • when there are problems with the brush assembly;

Electric brush assembly

  • in case of burning motor windings;
  • if jamming of the rotating parts occurs.

To eliminate the voltage problem, you need to use a multimeter or tester to check its value in the outlet from which the power of the electric braid is taken. If it is less than the minimum acceptable value, then to increase it, you will need to turn off all electrical appliances or install a stabilizer.

A prerequisite necessary for the normal operation of the trimmer is the use of an extension cord with a cross-section of conductors corresponding to the power of the engine of the braid.

To repair the soft starter, you will need to have the appropriate knowledge of electronics, so it is better to contact a service center. They will determine its maintainability or the need for replacement. You can independently check the button or find the block diagram and try to figure it out.

Soft starter

The brushes can wear out, as a result, the contact will disappear, which leads to motor stops. Brushes are easy to replace. Features of the process are determined by the applicable lawn mowing model. Along the way, you will also need to clean all contact surfaces.

If the windings burn out, if you continue to mow grass or shrubs, the electric motor will quickly burn out. This will be accompanied by the appearance of a burning smell, up to the melting of individual parts. You will need to replace the electric motor.

The wedging of the rotating parts occurs for various reasons. To identify and eliminate them, you will need to sort out the drive unit. There are models in which the number of revolutions is automatically adjusted depending on the load, increasing as it increases. their idle speed decreases.

The video shows an algorithm of actions to identify the most common causes for which the trimmer does not gain the required speed:


The market has a wide selection of trimmers from various manufacturers. They are characterized by common reasons why the momentum is falling. Also, each unit is equipped with an instruction manual. In it, the corresponding section contains the necessary recommendations on this issue regarding the model used.

If in the process of self-troubleshooting a positive result was not achieved, it is better to seek the help of specialists. Also, professionals should be involved in solving the problem in the absence of minimum experience and skills in such a case, so as not to harm. The most difficult unit is the engine. Only experienced craftsmen are allowed to work with it. When the lawn mower is under warranty service, the best option is to contact a service center where they will carry out diagnostics and repair of the equipment.
