Basic rules and techniques for working with a brushcutter.

To get good mowing results and long service life it is important to use and look after your brushcutter properly. Even if this is the first time you hold a brushcutter in your hands, you will soon get the hang of correct mowing techniques. Swing the machine simply in a semicircle from right to left, moving evenly forward. Below we show you the basic technique and some tricks with which you can quickly mow even large areas and achieve better results in mowing quality.

The basic mowing technique is the most common.

Because the cutting tool rotates counterclockwise, it is more common in working practice to mow from right to left.The advantage of this method is that the cuttings always fall on top of the cut surface.

A big, flat surface is the right way to go.

Huge, even surfaces are best mowed in a square shape. The area is divided into squares, then you always work along the outer side toward the center.

The basic technique in tall grass.

If you mow very tall grass or tough weeds it is a good idea to go both ways: first you cut the higher part of the cut in one direction to the right, then in the opposite direction (to the left) the lower part. The grass cuttings remain lying on the left in this case as well.

You perfectly advance in the way of straight mowing especially on a slope: mow one swath parallel to the slope and then go backwards on the mowed strip. Then mow the next one above. And here the grass cuttings are always placed on an already cut surface.

Skilfully negotiate obstacles. playfully mow.

To mow against trees or bushes without damaging any boughs or trunks, a string cutter is the best choice. How to make a grass trimmer hood from a grass trimmer boom hole and. If there are a lot of plants at a small distance from each other, mowing is suggested before mowing. Use your brushcutter’s protection as a guide. Always mow along a tree or a bush, and go round it. The trunk remains protected, the area around the trunk will be mowed.

How to Make the Right Fuel Mixture: Fuel = Petrol Oil

Oil. high quality two-stroke oil for high speed machines (10-15k. RPM, about 200 rpm). Do not use motorcycle oils (low engine speed) or water-based oils (different cooling system). their use does not provide the necessary lubrication for the piston group and all engine parts! You can use, for example, Husqvarna, STIHL or Champion oils.

How to make a muffler for a grass trimmer

The operating principle and design of brushcutters is not very different from any other small petrol-powered garden machine, such as a chainsaw, power tiller or hedge trimmer. How to make a self-made protection for the grass trimmer with your own hands. The brushcutter is based on a single-cylinder, 2-stroke carburetor-based gasoline engine (four-stroke less often), a manual starter motor and an air-cooling system. The engine runs on the fuel consistency of gasoline and 2-stroke motor oil, in the proportion of 1:50. The proportion of fuel may vary depending on the manufacturer’s recommendations in the instruction manual. Always adhere to the recommended proportion. The mowing attachment for your brushcutter is a mower drum with a line or an iron cutting blade, a saw. The transmission of engine speed to the mowing headset is as follows: crankshaft. clutch. clutch plate. drive shaft. bevel gear. mowing head (cutter).

Clean properly

In order to clean the chainsaw perfectly, you will need the following tools:

A set of tools can be seen in the photo.

Cleaning the chainsaw carburetor is worth creating according to the following method:

The main causes of chainsaw damage

Despite the fact that the chainsaw is a simple device, from time to time there are problems in its operation, which can be eliminated only by disassembly. The following malfunctions are examples:

  • The chainsaw won’t turn;
  • The chainsaw stops functioning in the cut;
  • The chainsaw starts and stops;
  • The chainsaw loses its power;
  • The chainsaw is pressed when it is pressed.

Most malfunctions are related to motor malfunctions, but also to malfunctions in other systems and components. Proper treatment of this equipment is essential. If all rules of use are followed, the problems are most likely to be the most obvious. It is wise to start troubleshooting by checking the simplest part of the chainsaw and ending with the most complex.

Why a chainsaw does not start well and forgets to start

Poor starting of the equipment in the cold can lead to insufficient compression, meaning the rings wear out over a long period of time and need to be replaced. Sometimes a problem with the muffler and poor contact between the spark plug and the wire is the cause of poor engine starting when there is no heat.

Poor starting can also be caused by a worn or damaged rubber collar gasket in the carburetor booster pump, which causes extra airflow, resulting in increased saw rotation.

Replace or flush the fine filter?

If the fuel filter is not yet depleted, it makes sense to wash it. To do it you use kerosene, acetone or blow it with air from an ordinary pump. However, not all drivers share this opinion and believe that if the engine malfunctions, it is necessary to promptly replace the fuel filter, especially if the car manual prescribes changing it after a certain mileage, thereby not interfering with the operation of the fuel system. The more that the cost of such a filter can do it without much difficulty.

It is too late to flush such a fuel filter, it should be replaced

Muffler scooter cleaning with his own hands

During the scooter operation, in the exhaust system gradually accumulates the residues of fuel and oil combustion, which leads to a noticeable deterioration in the work, whether it is a two-stroke or four-stroke engine.

The exhaust system clogged with soot may cause engine power reduction, occurrence of interruptions in operation, contributes to fuel overruns. When driving, when the throttle is opened sharply, the engine reacts very slowly and the acceleration of the scooter is very weak.

Exhaust pipes of two-stroke engines are more prone to fouling than those of four-stroke engines, although, on two-stroke engines, this problem affects the performance of the motor more. The motor is blown with its exhaust gases.

Detect contamination, can be quite simple, you need to dismantle the part and blow into the intake manifold. If you can feel any resistance to the air flow, it is necessary to clean. There are several ways of cleaning, which vary in efficiency and laboriousness.


The most radical, at the same time and the most time-consuming method, which gives the best result. cutting, and removing fouling with various scrapers and tools, and then welding. Know the inner workings of the system. Usually, on the side, a rectangular window is cut through which the work is done. After the muffler is welded, it will have to be painted to restore the aesthetic appearance.

It is easier to remove fouling with a cable. You need to take a piece of cable of the required length, clamp one end of it into the chuck of an electric drill, and the other end to ruminate, and gradually move it inside by turning the cable with the drill at low speed. In some cases, a positive result is obtained.


You can clean chemically. This method is considered more effective than using a wire. As a cleaning “chemistry” you need to take a household cleaner for sewage pipes, such as “Mr. Muscle”, “Cat” or other similar means on an alkaline basis.

Start by plugging one end of the exhaust pipe, make sure it is airtight, then pour the powder into the muffler, fill it with hot water, and leave it like that for 24 hours.

The next day, pour out all the “dirt” together with the cleaning compound and rinse well with running water from a hose. After that, dry it and install it on the scooter.


The next method of cleaning can be called a thermal one, i.e. it is burned with a blowtorch or simply in a fire. It should heat up, what is called “up to redness”. You can point the lamp flame inside the system as the exhaust fumes travel. Do it until there is no longer any smoke from the burned residues.

After such firing, all the soot is shaken out, blown with compressed air from a compressor, and painted with heat-resistant paint.

Hopefully, at least one of the above cleaning methods will help restore the performance of the exhaust system. Accordingly to increase engine power and quality of work.
