The trimmer does not develop speed: the main problems and how to solve them - Setafi

One of the common problems is that the trimmer does not develop or gain momentum. What is the reason for this: bad parts, improper operation, low-quality gasoline? Or maybe the wife was tired of the constant noise, and she decided to “twist” the garden tool so that it would stop buzzing all day? In our article, we will analyze in detail the solution to the problem of "why motokosa is not gaining momentum." Go!

Motor scythe engine speed - how the tool works in practice

Any trimmer uses fuel for its work - gasoline or electric. The first ones are several times superior to the second category both in terms of productivity and the quality of components, but this is not the topic of our article. We will focus on the general basis of the operation of the device.

The lawn mower works as follows: the engine (two- or four-stroke, electric motor) under the influence of fuel sets the shaft in motion, and it transmits torque to the spool. There are modifications where the procedure is carried out without a shaft - the engine is installed at the bottom of the device and directly transfers the revolutions to the working base.

All elements are mounted either on a solid rod or on a flexible shaft. A handle with keys for operation and a starter are also installed there.

Since the reason is that the trimmer is gaining momentum poorly, it is more typical for gasoline options, we will pay special attention to this category. Most of its malfunctions are directly related to improper use of the device or ignorance of elementary maintenance rules. As a result, the lawn mower refuses to work and does not gain momentum.

Always read the user manual before using. It also describes possible situations why the trimmer is not gaining momentum.

When you first turn on, follow this sequence so as not to harm the performance of the equipment:

• Turn on the start of revolutions on the handle;
• Click on the silicone choke for gasoline, which is located near the engine. You need to do this about 3-5 times;
• Close the air duct on the filter;
• Set the throttle lever to maximum speed. There is a latch on the lawn mower so that the lever does not fly off when the engine is started;
• Turn on the electric starter or pull the starter lacing several times until the characteristic sound and spool turns.

If the brushcutter turns on, but does not pick up speed and stalls, put the air duct in the half-open position and repeat the process. When the device is working, press the lever to slow down. Open the air valve and start mowing.

The gas trimmer does not develop full power - what is wrong

The problem arises when the engine is idling normally, and when you press the lever, the gasoline trimmer does not pick up speed and may even stop.

The problem is not uncommon and occurs even in the most popular types of models and manufacturers. For example, from a long downtime, the calm trimmer may not gain momentum.

When working with the trimmer, constantly monitor its condition. One uncharacteristic sound can cause a breakdown and the purchase of a new device. For greater safety, if the device behaves "differently" - stop, turn off the system and wait 15-20 minutes, let the machine cool down. And if the problem has not disappeared, we are looking for the reason why the lawn mower is not gaining momentum.

Reasons that the trimmer does not develop speed

External signs

The reasons that the lawn mower is not gaining momentum vary. Some are not even related to the breakdown of the device, for example:

• Dirt or dust on the filter.
• Filling with low-quality fuel mixture.
• Use of bad gasoline or expired oil.
• Contamination of engine components, which does not allow the device to gain momentum.

In case of contamination, a lot of soot presses on the carburetor. He is the reason that the trimmer is not gaining momentum.

Internal problems of the fact that the gasoline trimmer does not develop speed

Technical malfunctions appear in both old and new devices. Do not be surprised - even a new trimmer engine may not develop speed. We check the ignition and mixture supply system for serviceability:

1. When the scythe starts and slows down or even does not start, then the problem may be in the candle. Dark soot appears on it - a sign of poor-quality gasoline and poor carburetor performance.
2. A flooded fuel hose is another problem that keeps the calm from gaining momentum.
3. During prolonged operation without cleaning the parts, the muffler may also become clogged. Check the system for dark particles and clean the pipe, then the engine will start and start working like new.

If the problem is in the motor itself and you don’t know what else to do, be sure to take it to any master. On your own inside the motor, you are unlikely to do something, all the more correctly. And you still have time to harm the device.

Maintenance of parts of the gas trimmer to prevent a problem

In order not to disassemble the lawn mower by cogs in vain, it is worth diagnosing each zone separately - the problem can be in one or several parts. Where to look and what to check - read on.

Carburetor

One of the main components of the correct operation of the trimmer. For the part to function as it should, adhere to the conditions:

• Remove and clean the part every month;
• Set the idle according to the manufacturer's instructions;
• If you can't do the setup yourself, take it to the master.

One of the most popular causes of engine failure is that the carburetor cable is not tight. To fix the problem, you must first disassemble the carburetor, clean it, and only then tighten the cable. Just do not overdo it so that it does not stretch like a string.

It is worth checking additionally: the inlet needle, membrane, tuning lever, dampers and other components of the carburetor. They may also have problems that interfere with the correct operation of lawn mowers.

Spark plug

Even if you don’t know what a normally working candle should look like, just remove it, dry it and clean it with sandpaper. Put the item back in place.

You can also check the distance on the main part. Maximum - 1 mm gap between the parts of the igniter.

If the candle is too black, then there is no point in cleaning it - just buy a new one and install it on the motor. Then the whole system will work with renewed vigor.

Filtration system

A clogged air filter can sometimes affect performance even more than spark plug problems. To check if the problem is in it, start the engine with the filter removed. If wound up, wash the filter sponge in gasoline or other detergent. Or you can buy a new one - it will only benefit your trimmer.

Clogged filters do not allow the fuel mixture to pass into the engine, so it stalls or does not start. The lack of gasoline can be corrected by simple cleaning: both the filter under the cover and the fuel hose filter (located inside the plastic fuel tank).

Motor malfunctions

The internal combustion engine is the basis of the operation of a gasoline apparatus. What could be wrong with it if the motor does not gain power:

1. The fuel mixture is incorrectly prepared, or its expiration date has long expired;
2. Piston rings are broken;
3. Cylinder or piston in scratches and cracks;
4. The device is used without interruption.

With the repair of the motor, you should be careful. This is because if you fix all the details incorrectly, you can be left without a trimmer, as well as with injuries. Entrust the matter to a specialist!
