The Petrol Trimmer Does Not Develop Speed

22nd August 2020

Spark plug problems

When the petrol trimmer is used frequently, the condition of the spark plugs must be monitored. This part is subject to wear and tear, so they need to be regularly inspected for carbon deposits.

There are two ways to solve the problem: clean an old candle from burning or purchase a new one.

In the first case, you need to unscrew and scrub with sandpaper, dry. The distance between the electrodes should be 1 mm. The trimmer is assembled and started.

In the absence of a spark between the electrodes, it is worth inspecting the quality of the connections of all circuit elements. If everything is fine in this case, then 100% need to change the candles.

Replacing them is easy and inexpensive. From tools you will need a key, file.

Important! With the frequent appearance of carbon deposits on the combustion plugs, it is worth looking for the reason a little deeper.

Candles should be thoroughly cleaned of plaque.

Low quality fuels

The benzotrimmer does not pick up speed in the case of poor quality fuel. It may stall or not start at all. To check the quality of the fuel, you need to inspect the spark plugs. They are the main indicators for problems with the combustion chamber.

In the presence of sediment formed on the candles, plaque, the old fuel is drained and another, high-quality.

It must be remembered that the trimmer or lawn mower must be filled with good quality gasoline and those brands of fuel that the manufacturer indicated in the technical passport of the device.

For your information! The candles should be thoroughly cleaned of plaque, and only after that they should be placed in the combustion chamber again.

For some reason, the Stihl electric scythe does not develop its full power

When using the electric trimmer, speed problems can also occur. The reasons here are completely different than those of fuel braids.

You can fix problems yourself

The trimmer does not develop the required power because:

The voltage in the network is below the required minimum for the device more than 10%;
There was a failure in the soft start (if such a system is available);
There was a malfunction of the brush assembly;
The motor winding is burnt;
Rotating parts sometimes jam.

To adjust the voltage, you should first check its power. If it does not meet the standards, you should increase it with a stabilizer.

Repair of the soft start system is carried out only in the service center.

Note! When the brushes wear out, you just need to replace them. When installing new ones, it is recommended to clean all surfaces with which they come in contact.

To adjust the voltage, you should first check the power.

If the motor windings are burning, you need to change the electric motor.

Jamming of rotation parts can occur for various reasons. To eliminate them, you should revise the entire drive assembly.

For your information! The latter problem may also arise with another unit of this Stihl pruner, and sharpening the disc with scissors will be its solution.

Reasons why the lawn mower does not develop momentum

There are five main reasons why the Stihl trimmer does not develop speed:

Dirty air or fuel filter

If the lawn mower is not gaining momentum, the reasons may lie in the contamination of the filter element: air or fuel.

The Petrol Trimmer Does Not Develop Speed

When the air filter becomes clogged, there is a lack of oxygen in the combustion chamber, so the fuel is not fully produced, which prevents the development of the required speed and power.

To check if the reason is the air filter, you need to remove it and turn it on. If the lawnmower is still not picking up speed, it’s not the cause. So you should check the fuel filter element. Here everything is the same, only gasoline acts as oxygen. If this filter is damaged, there will be a lack of fuel, which slows down the development of speed.

Engine problems

Engine problems are more serious. Several variants of the problem are possible:

Damaged carburetor;
Drive problems.

In the case of a carburetor problem, you should first pay attention to the condition of the cable. It may be weakened, which is what caused the problem. This requires a simple cable adjustment.

If this does not help, then you need to check the usage parameters. The stated performance standards can be found in the technical data sheet of the device. Sometimes it is enough to disassemble the device: wash, clean and assemble.

Note! The solution to the problem with the carburetor can be the purchase of a new element or contacting the service for professional services.

The trimmer drive is only fully checked if the manipulation of the carburetor does not give the desired result.

Build your Home! Recommendations for use

It is necessary to take temporary breaks from work. Mower does not develop speed Diagnostics and Lawn Mower Trimmer Stalls at. This is necessary so that the engine of the device does not overheat and fail prematurely. Lawn mower does not develop Dismantling the Stihl 180 chainsaw Stihl FS 55 is not gaining momentum? Yes. For amateur models, there is a break every 20 minutes for the same time. For professional mowers, work should be interrupted 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 period of time, it is better to drain the remaining fuel from the tank compartment. This will help avoid damage to engine parts.

If you put a cable instead of a fishing line, without the possibility of releasing it, securely fixing the two ends of the cable and cutting them off by welding (a drop of melted metal keeps the cable from unraveling). Such a tool knocks grass at a time. Cuts off shoots up to about a finger thick. Not as afraid of stones as a disc. There is, however, a problem: when worn, pieces of the cable thread break off, and these twisted wires remain in place of the mowing. Stepping on them can cause injury.

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

Benzotrimmer loves cleanliness. It is necessary to monitor the cleanliness of the air filter and fuel. Gasoline bought at a gas station is better to stand for 2 days and pass a piece of bike cloth through a simple filter.

We check the electrical equipment as follows:

1. Unscrew the candle, inspect the gap between the electrodes. We can set the correct gap between the electrodes in an old-fashioned way. Take the razor blade, cut it in half and insert a homemade probe between the electrodes. If the blades fit tightly, then the gap is perfect.

2. Put the high-voltage wire cap on the candle and lean the candle against the metal surface of the engine. We pull the starter several times. If the spark hits one point well, then the gap is adjusted correctly. If there is no spark is weak or wanders, then it is necessary to re-adjust the gap between the electrodes.

Possible causes of a problem with electric streamers

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

If the voltage 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 scythe brush unit

In case of burning of the engine windings;
If wedging of rotating parts occurs.

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

A prerequisite for the normal operation of the trimmer is the use of an extension cord with a conductor cross-section corresponding to the power of the streamer motor.

To repair the soft starter, you will need to have the appropriate knowledge in electronics, so it is better to contact a service center. There they will decide on its maintainability or the need for replacement. You can check the button yourself or find the block diagram and try to figure it out.

Soft starter block

The brushes may wear out and contact will be lost as a result, causing the motor to stall. The brushes are easy to replace. The features of the process are determined by the lawn mower used. Along the way, you will also need to clean all contacting surfaces.

If the windings are burnt, if you continue to mow the grass or bushes, 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.

Wedging of 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 with its increase; at idle speed, the rotation speed decreases.

Shown is an algorithm of actions to identify the most common reasons why the trimmer is not gaining the required speed:

The numbers mean the following: one part of the oil takes fifty parts of gasoline. Hence: 1000 ml (1 liter of gasoline) divided by 50, we get 20 ml, that is, 1:50.

Thus, you can calculate the composition of the fuel mixture (gasoline / oil) in any proportions. To add oil to gasoline not by eye, you can advise to take a 20 ml medical syringe, draw oil into it and inject it into a container for preparing a fuel mixture.

Lawn mower not develops momentum.Another one cause

Chinese lawn mower analogue of Husqvarna does not develop momentum reason turned out to be very simple (look at)

If you have done the operations with the filter, but the work of the trimmer, powered by gasoline, remains the same, the petrol trimmer is not gaining momentum what to do?

Then you should try to remove the filter from the device in order to provide so-called trimmer relief. Why the Chinese lawnmower doesn’t pick up speed is the reason for Husqvarna. Should help.

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

In this case, the problem might be:

The last and most common reason for a petrol trimmer breakage is that the cable in the carburetor section has simply fallen asleep.

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

Why does the trimmer speed drop?

This common problem has a variety of different causes. While working with the device, you can encounter both obvious malfunctions, the signs of which are clearly traced, and asymptomatic cases. The first option is the simplest from the point of view of finding a problem. If the trimmer does not pick up speed, and there are no clear signs of breakdowns, then you will need to consistently check the most typical cases of malfunctions, and if the cause is found, eliminate it.

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

The trim tabs are fitted with vacuum carburetors. When disassembling, cleaning or washing it, you need to be extremely careful not to disassemble the lower part of the carburetor where the primer is located. The air filter (visible when you remove the protective cover from the carburetor) must be washed with detergents. Best for dishwashing. After drying, put it back. We wash the carburetor with clean gasoline and blow through all the holes with a pump. We also wash the fuel line filter, then dry and collect everything. Usually, after all the manipulations, the trimmer starts working.

A thin cable instead of a fishing line, is it worth using on the lawn mower?

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

Construction and Dacha in plain language

What to do if the benzotrimmer is not gaining momentum?

If you have once purchased a trimmer that runs on gasoline, then you probably had to deal with the problem of turning on the trimmer, as well as with such a problem as the petrol trimmer does not gain revs.

That is why this article was created.

So, what to do if the trimmer, which has been working for you for more than a year, suddenly just stops picking up speed, and the engine simply stalls? In this case, you and I should consider a number of problems associated with stopping the motor.

The motor can stall under various circumstances. Why the lawn mower turns. I can’t get it off the ground. And it is gaining momentum from the floor. Sometimes the reason for the improper operation of the trimmer, running on gasoline, is a clogged air filter.

It is the filter that is one of the most important reasons why the gasoline trimmer may stop working.

Various debris 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 what power the gasoline trimmer has, as well as how much often you use this device.
