The modern market offers a wide range of electric and fuel-powered trimmers from different manufacturers. Malfunctions may occur in the operation of the equipment. For example, the lack of speed. Do not panic about this, since the problem of insufficient speed in lawn mowers, trimmers is quite common. There are several reasons for this.
Reasons why lawn mowing does not develop
There are five main reasons why the Stihl trimmer does not develop momentum:
Low quality fuel
The gas trimmer does not gain momentum 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 precipitate formed on candles, plaque, the old fuel is drained and poured another, high-quality.
It must be remembered that the trimmer or lawn mower must be refueled with good quality gasoline and those brands of fuel that the manufacturer indicated in the technical data sheet of the device.
For your information! Candles should be thoroughly cleaned of plaque, and only then placed in the combustion chamber again.
Air or fuel filter contamination
There is a lawn mowing not gaining momentum, the reasons may lie in the pollution of the filter element: air or fuel.
When the air filter is clogged, there is a lack of oxygen in the combustion chamber, so the fuel is not fully developed, which prevents the desired speed and power from developing.
To check whether the cause is really in the air filter, you need to remove it and turn it on. If the lawnmow is still not gaining momentum, the reason is not in it. So you should check the fuel filter element. Everything is similar here, only gas plays the role of oxygen. If this filter is damaged, there will be a lack of fuel, which slows down the development of revolutions.
Problems with spark plugs
When the gas trimmer is used often, you need to monitor the condition of the spark plugs. This part is subject to wear and tear, so they need to be inspected regularly: for deposits.
There are two ways to solve the problem: clean the old candle from burning or purchase a new one.
In the first case, you need to unscrew and scrape sandpaper, dry. The distance between the electrodes should be 1 mm. The trimmer is collected and turned on.
In the absence of a spark between the electrodes, it is worth examining the quality of the connections of all elements of the circuit. If everything is fine in this case too, then 100% need to change the candles.
Replacing them is simple and inexpensive. Of the tools you will need a key, a file.
Important! With the frequent appearance of soot on combustion candles, it is worth looking for a reason a little deeper.
Candles should be thoroughly cleaned from plaque.
Engine problems are more serious. There are several possible problems:
- the carburetor is damaged;
- drive problems.
In the case of a carburetor problem, you should first of all pay attention to the state of the cable. It can be weakened, which led to a malfunction. A simple cable adjustment is required here.

If this does not help, then you need to check the usage parameters. The specified operating standards can be found in the technical data sheet of the device. Sometimes it’s enough to disassemble the device: wash, clean and assemble.
Note! The solution to the problem with the carburetor may be to buy a new element or contact the service for professional services.
The trimmer drive is only fully tested if manipulation of the carburetor does not produce the desired result.
Failure in the fuel circulation system
The lack of fuel circulation in the system can also be the reason why the device is not gaining momentum. There are several options why this happens:
- cracks in the hose, due to which air leaks;
- fuel pump clogging;
- clogged catalyst or muffler.
You can fix the problems yourself. To do this, you need:
- remove blockages from the fuel pump;
- renew hoses, pipes for fuel circulation;
- clean the muffler and the mesh on it;
- mount a new catalyst.
Do not worry when such problems occur. This does not mean that the unit is of poor quality. If the Patriot trimmer does not gain momentum, you can fix it yourself without contacting the service.
For what reason the Stihl electric braid does not develop full power
When using the electric trimmer, problems with revolutions may also occur. Here the reasons are completely different than fuel braids.
You can fix the problems yourself
the trimmer does not develop the required power, because:
- mains voltage below the minimum required for the device is more than 10%;
- there was a failure in a smooth start (if there is such a system);
- a malfunction of the brush assembly has occurred;
- motor winding has been burned;
- rotating parts sometimes jam.
To fix the voltage, you should first check its power. If it does not meet the standards, it should be increased with a stabilizer.
Repair the softstarter only at the service center.
Note! When the brushes are worn, they just need to be replaced. 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.
With burning motor windings, you need to change the electric motor.
Jamming of rotation parts can occur for various reasons. To eliminate them, the entire drive assembly should be reviewed.
For your information! The latter problem may arise in another unit of this company. the Stihl secateurs, and sharpening the disc with scissors will be its solution.
How to start a Stihl lawn mower
The main steps to start a Stihl lawn mower:
- Before operating the petrol trimmer, read the instructions and check the Stihl trimmer for each part. After you can collect it.
- An important step is the preparation of fuel and refueling. Prepare the mixture in a measured container. Gasoline and oil are poured into it in the indicated ratio. Using a funnel, the mixture is poured into the fuel tank.
- At first start up, 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 started or not.
A first run may require up to 15 jerks. After starting the engine, it is worth turning on idle for warming up. After a while, it is stopped with the Stop button.
Note! This manual is universal, because in order to start the Stihl lawnmower, you need to perform similar 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 the mains, therefore it is important to provide sufficient power so that the trimmer can gain momentum.
After each operation, both the gasoline and electric trimmers require a thorough inspection.
Following the instructions, you can quickly fix any small breakdown yourself. But sometimes you can’t start the unit with your own hands. In this case, it is better to seek professional help, especially if this relates to a problem with the engine and the development of revolutions at the trimmer or lawn mower.
