The modern market offers a wide range of electric and fuel-powered trimmers from various manufacturers. Equipment may malfunction. For example, insufficient RPM. Do not panic about this, since the problem of insufficient speed in petrol mowers, trimmers is quite common. There are several reasons for this.

The reasons why the brushcutter does not develop speed

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

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 candles. They are the main indicators for problems with the combustion chamber.

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

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

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

Dirty air or fuel filter

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

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 brushcutter is still not picking up speed, the reasons are not in it. 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.

In one and the other case, the solution is simple: you just need to replace the filter. If you have a spare, to install it, if not, to purchase it in any specialized store, it is inexpensive.

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, therefore they need to be inspected regularly 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 the tools you will need a key, a file.

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

Candles should be thoroughly cleaned of plaque.

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.

Failure in the fuel circulation system

Lack of fuel circulation in the system can also be the reason why the unit is not picking up speed. There are several options for why this happens:

  • cracks in the hose, which causes air leaks;
  • clogged fuel pump;
  • clogged catalyst or muffler.

You can fix the problems yourself. For this you need:

  • remove blockages from the gas pump;
  • renew hoses, pipes for fuel circulation;
  • clean the muffler and the mesh on it;
  • install a new catalyst.

Don't worry if you have such problems. This does not mean at all that the unit is of poor quality. If the Patriot trimmer is not gaining momentum, you can repair it yourself without contacting a service.

For some reason, the electric braid Calm does not develop its full power

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

You can fix problems yourself

Trimmer Calm electric

The electric 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 engine 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 the 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, the electric motor must be replaced.

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

Note! The latter problem can arise with another unit of this company - the Stihl secateurs, and sharpening the disc with scissors will be its solution.

How to start a brushcutter Calm

The main stages of how to start a brushcutter Calm:

  1. Before using the gasoline trimmer, you should read the instructions and check the Calm trimmer for the presence of each spare part. Then you can collect it.
  2. An important step is fuel preparation and refueling. You need to prepare the mixture in a measuring container. Gasoline and oil are poured into it in the specified ratio. Using a funnel, the mixture is poured into the fuel tank.
  3. At the first start, turn on the ignition without opening the air damper. Place the device on a flat and smooth surface for stability. Now - you need to sharply pull the cord 3 to 5 times. The choke can be opened in any case: the engine starts or not.

The first start can take up to 15 jerks. After starting the engine, it is worth turning on idle to warm up. After a while, it is stopped with the Stop button.

Note!This instruction is universal, since in order to start the Stihl lawn mower, you need to follow the same steps.

In the case of starting an electric trimmer, everything is much simpler: you need to read the instructions and act in accordance with it. Instead of fuel, there is electricity.The appliance is powered by mains, so it is important to provide sufficient power to allow the trimmer to rev up.

Both the petrol and electric trim tabs require a thorough inspection after each use.

By following the instructions, you can quickly fix any minor damage yourself. But sometimes it is not possible to start the unit with your own hands. In this case, it is better to seek professional help, especially if it relates to a problem with the engine and the development of rpm at the trimmer or lawn mower.
