Benzokosa repair: review of malfunctions and effective methods for solving them. Photo instruction from the pros!

Modern technologies and equipment make it possible to produce the best and optimal technical solutions, which become effective assistants in the arrangement of a suburban or personal plot. The green lawn and other plantings can grow rapidly, to clean up the house territory and mow the lawns, a brushcutter is used, which is also called a brushcutter or trimmer, a brushcutter.

Traditional braids are inconvenient and unsafe to use, require a significant investment of time and their own forces, which will help to save petrol scythes, combining functionality and practicality in their design. In the photo of the brushcutter, you can see various high-tech devices that have a set of operational characteristics, including such parameters as increased productivity and long life.

A convenient and reliable trimmer is a technical device consisting of individual mechanisms, parts and elements that may wear out, become unusable and be damaged during intensive use.

Even during regular technical inspections, care and storage procedures, such devices and their individual parts require repair and even replacement, all repair procedures can be carried out independently.

Device mowers and common malfunctions

The easiest way is to give the brushcutter for repair, having allocated a certain amount of funds from the family budget, quick and high-quality DIY repair is no less simple and convenient if you want to understand the design of the brushcutter and fix all the problems.

Mass and piece production of trimmers is based on the use of generally accepted technology, a typical design scheme consists of certain elements and parts, it is important to know them when performing independent repair work:

top part. The basis of the entire structure, where all the important elements are assembled, such as a starter, a carburetor and a brushcutter engine;
middle part. A hollow rod, inside it is a cable connecting the engine and gearbox, which drives the cutting line. In this part there are fasteners for distributing the weight of the entire structure and a belt for fixing the trimmer on the belt of a person using the trimmer for its intended purpose;
Bottom part. It contains a gearbox and cutting elements that are hidden under a practical casing, which protects the user. The casing provides an increased level of security, preventing large fractions of debris, pebbles and glass from entering the person during work with the brushcutter.

Knowing exactly the internal structure and the principle of operation of the trimmer, one can independently carry out repair measures for the design or replace individual, worn-out units using the repair instructions.

The most common and often encountered, subject to self-correcting breakdowns of the unit can be called the following problems:

engine malfunction, due to which the brushcutter does not start and does not work;
reinforced vibration of the motokosa rod, which complicates its intended use;
increased overheating of the gearbox, its accelerated heating during operation;
slow and weak functioning of the cutting line at low speeds;
clogging of the starter grate, causing the engine to overheat and to refuse to work;
fast and frequent clogging of the carburetor due to the use of low-quality fuel;
clogged air filter when non-observance of device care measures.

All these problems can lead to the fact that the device will lose its working capacity. Before ordering the necessary spare parts for brushless ones, a visual inspection and diagnostics of the device should be carried out.

Particular attention is required to individual spare parts and units of the device, you will not have to contact a professional master to check them, a set of diagnostic measures will help you identify the consequences of a loss of working capacity.

Determining the causes of the malfunction

If the trimmer motor does not start or stalls immediately after starting, when the gearbox overheats or during the operation of the device, extraneous noise is heard and vibration is clearly felt, it is important to visually inspect and identify an inoperative unit.

To optimize the preparatory measures before the repair, a simple diagnosis should be made and a step-by-step check should be carried out:

the presence of fuel in the tank and lubrication in the main components;
the serviceability of the spark plug and its performance;
cleanliness of the fuel and air filter;
clogged exhaust channel and breather device;
quality of used fuels and lubricants.

To determine the functional performance of the ignition of the brushcutter, it is necessary to determine whether the candle works by testing the appearance of a spark in contact with the body of the functional device.

The spark plug itself can be replaced with a new one, having previously dried the candle channel, if necessary, the old element is also dried, cleaned with special tools and returned to its place.

Carburetor repair

In the process of inspecting the carburetor, it is worth paying attention to the possible leakage of the fuel used, in order to identify problems with the carburetor, the following measures should be taken:

purging the fuel hose to eliminate possible clogging of the element;
checking and replacing the gasket located between the engine and the carburetor;
determination of tightness and maintaining a constant pressure in the unit.

If necessary, one can personally disassemble and thoroughly clean the unit using gasoline, cleaning the nozzle and channels using compressed air.

Starter and gear failure

The gearbox transmits the torque from the motor shaft to the cutting tool, its gears must be absolutely clean and must be lubricated with special grease during operation.

Conducting a technical inspection on their own once a season will eliminate the need to repair the gearbox or replace it with the purchase of an expensive new unit.

The starter is necessary to bring the trimmer to working condition; its diagnostics consists in checking the tension of the cord of the starter coil coupled to the teeth, which often collapse upon abrupt start.

A non-working starter in a gas brush can not be repaired, it must be replaced with a working unit, as part of a mandatory inspection or a set of repair measures.

Special attention and care is required by cutting elements, which must always be cleaned of dirt and mowed grass after use. Regular inspection and thorough preparation of the device for operation will help to avoid costly and time-consuming repairs, and always be sure of the operation of the brushcutter.
