During prolonged operation, sparks came from the brush-collector motor of the trimmer and knocked out the machine on the counter. After the trimmer had cooled down, it was turned on again, but the traffic jams were knocked out again (the button on the trimmer was not even pressed). The apparatus was disassembled - there was no visible damage, there was no burning or smell, there was no smoke.
What could be the reason for what can be done? Thanks in advance.

Due to a malfunction, it is possible that there is a short in the power cord at the rubber band to the engine, or at the plug. What is the power of the trimmer. Name. preferably a photo of the engine with a visible manifold.

Modern technologies and equipment make it possible to produce the best and optimal technical solutions that become effective assistants in the arrangement of a summer cottage or a personal plot. The green lawn and other plantings can grow rapidly, a petrol cutter is used to tidy up the local area and mow the lawns, which is also called a brushcutter or trimmer, a petrol mower.

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

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

Even with regular technical inspection, maintenance procedures and careful storage, such devices and their individual parts require repair and even replacement, all repair procedures can be performed independently.

Brief content of the article:

The easiest way is to give the petrol cutter for repairs, having allocated a certain amount of funds from the family budget, prompt and high-quality repair with your own hands is no less simple and convenient if you want to understand the design of the petrol cutter and fix all the problems.

The 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 carrying out independent repair work:

top part.The basis of the entire structure, where all important elements are collected, such as a starter, a carburetor and a petrol cutter engine;
middle part. A hollow rod, inside it is a cable that connects the motor and the 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 houses the gearbox and cutting elements, which are hidden under a practical cover to protect the user. The casing provides an increased level of safety, preventing large fractions of debris, stones and glass from entering a person while working with a petrol cutter.

Knowing exactly the internal structure and the principle of operation of the trimmer, you can independently carry out repair measures for the structure or replace individual components that have become unusable, using the repair instructions.

The most common and common failures of the unit that need to be corrected on their own include the following problems:

engine malfunction, due to which the brushcutter does not start and does not work;
increased vibration of the brushcutter bar, which complicates its intended use;
increased overheating of the gearbox, its accelerated heating during operation;
slow and weak functioning of the cutting line at insufficient speed;
clogging of the starter grille, causing overheating of the engine and its refusal to work;
fast and frequent clogging of the carburetor due to the use of low-quality fuel;
clogging of the air filter due to non-observance of the measures for the care of the device.

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

Particular attention should be paid to individual spare parts and units of the device, to check them you do not have to contact a professional master, a set of diagnostic measures will help you to identify the consequence of a loss of performance with your own hands.

If the trimmer motor does not start or stalls immediately after starting, when the gearbox overheats or during the operation of the device, extraneous noises are heard and vibration is clearly felt, it is important to visually inspect and identify a non-working unit.

To optimize the preparatory measures before repairs, you should carry out a simple diagnosis and check step by step:

the presence of fuel in the tank and lubrication in the main units;
serviceability of the spark plug and its performance;
the cleanliness of the fuel and air filter of the brushcutter;
clogging of the outlet channel and breather of the device;
the quality of the fuels and lubricants used.

To determine the functional efficiency of the petrol-cutter's ignition, it is necessary to determine whether the spark plug is working by testing the appearance of a spark when it comes into 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 devices and returned to its place.

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

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

If necessary, you can personally disassemble and thoroughly clean the unit using gasoline, the jet and channels are cleaned using compressed air.

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

Carrying out a technical inspection on your own once a season will allow you to get rid of 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 into working condition, its diagnostics consists in checking the tension of the starter cord connected to the teeth of the starter coil, which are often destroyed during an abrupt start.

An inoperative starter in a petrol cutter cannot be repaired; it must be replaced with a working unit as part of a mandatory technical inspection or a set of repair measures.

Cutting elements require special attention and care, which must always be cleaned of dirt and cut 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 confident in the performance of the petrol brush.

The benzokos is one of the main tools of the summer resident, used to quickly put the land in order. Owners of private houses also purchase this tool for mowing grass in the backyard. The period of active use of petrol cutters and electric trimmers is in the summer. Before starting operation, the tool is put into working condition: rubbing parts are lubricated, the cutting attachment is changed, a fuel mixture is poured into the tank. If the engine does not start at all or stalls quickly, without gaining a sufficient number of revolutions, then you have to look for the causes of the malfunctions and eliminate the identified malfunctions. To repair a petrol brush with your own hands, you need to understand its structure and the principle of operation of the main units. This information can be found in the instructions for use, which the manufacturer applies to the garden equipment without fail. Check for such a guide when purchasing your chainsaw. The imported tool must be accompanied by instructions written in Russian.

A long tubular rod is attached to the gearbox of a two-stroke internal combustion engine. A shaft passes inside the rod, which transfers torque from the gasoline engine to the cutting mechanism. The line or knives rotate at 10,000 to 13,000 rpm. There are holes in the protective housing of the gearbox, into which grease is injected with a syringe. For the convenience of using the tool, the manufacturer equips it with a special adjustable shoulder strap.

A cutting attachment is attached to the brushcutters:

The line, which varies in thickness from 1.6 to 3 mm, is located in the trimmer head. The line is subject to wear during mowing. Changing the line is quick and easy in two ways: by winding a line of the same diameter onto a bobbin or by installing a new spool with line already wound.
Steel knives with double-sided sharpening for the benzokos for clearing the area from weeds, small bushes, hard grass. Knives differ in shape and the number of cutting surfaces.

On the U-shaped, D-shaped or T-shaped handle, which is attached to the boom, there are the petrol cutter control levers.The cutting mechanism is protected by a special casing. Household brushcutters are filled with a mixture prepared from gasoline and oil, which is poured into the fuel tank. The device of semi-professional and domestic brushcutters, equipped with a four-time gasoline engine, is slightly different. The filling scheme is also different: oil is poured into the crankcase, and gasoline is poured into the tank.

The measured piece of fishing line is folded so that one end is 15 cm longer than the second.We put the loop into the slot on the spool and start winding in the direction indicated by the arrow

If you cannot start the petrol cutter, then the first step is to check the presence of fuel in the tank and its quality. For refueling the tool, it is recommended to use high-quality gasoline purchased at gas stations, the grade of which should not be lower than AI-92. Saving on cheap fuel can lead to a breakdown of the cylinder-piston group, the repair of which can take a third of the cost of the brushcutter itself. It is equally important and correct to prepare the fuel mixture from gasoline and oil. The proportional ratio of these components of the mixture is indicated by the manufacturer in the manual. It is not necessary to prepare the fuel mixture in large volumes, since its properties are lost during long-term storage. Better to use a freshly prepared mixture.

When preparing the fuel mixture, pour oil into gasoline using a medical syringe, which allows you to accurately observe the required proportion of components

A dirty fuel filter in the tank can also prevent the brushcutter from operating. Therefore, if problems arise with starting the motor, check the condition of the filter. Replace the filter if necessary. Do not leave the inlet pipe without a fuel filter.

The air filter also needs to be checked. When contaminated, the part is removed, washed in gasoline in the field and put in place. In the country or at home, the filter can be washed in water using detergents. After that, the filter is rinsed, wrung out and dried. The dried filter is moistened with a small amount of oil used to prepare the fuel mixture. Excess oil is removed by squeezing the filter with your hands. Then the part is installed in place. The removed cover is put back and secured with screws.

The air filter, washed in a fuel mixture, wrung out and dried, is installed in place in a plastic case and closed with a lid.

You can see how this procedure is done in more detail in the video:

If all of the above procedures are carried out, and the engine does not start, then adjust its idle speed by tightening the carburetor screw. In the video posted at the beginning of the article, attention is paid to this issue.

Place the tool on its side with the air filter at the top. This arrangement of the chainsaw ensures that the fuel mixture hits the bottom of the carburetor. The engine will start on the first attempt if you remove the air filter and pour a few drops of the mixture into the carburetor before starting, then reinstall the dismantled parts. The method has been tested in practice.
If the first tip doesn't work, then the problem is most likely in the spark plug. In this case, unscrew the plug and check its functionality, and also dry the combustion chamber. Replace the candle that does not show signs of life with a new one.
If the spark plug is in good working order, the filters are clean and the fuel mixture is fresh, then you can use the universal method of starting the engine. Close the carburetor choke and pull the starter handle once. Then open the choke and pull the starter 2-3 more times. Repeat the procedure three to five times. The engine will definitely start.

Some pull the handle with such force that they have to repair the starter of the petrol cutter with their own hands. This is only possible if the cable breaks or the cable handle breaks. In other cases, it is recommended to replace the starter. This unit is sold assembled.

Stop the engine and wait for it to cool down.
Disconnect the high voltage wire from the spark plug.
Unscrew the part using a special wrench.
Inspect the spark plug for replacement. The part changes if it is faulty, heavily soiled, has a crack on the case.
Check the electrode gap. Its size should be 0.6 mm.
Tighten the new spark plug inserted into the engine with a wrench.
Install the high-voltage wire to the center electrode of the spark plug.

As you can see, there is nothing super complicated in this procedure.

A new spark plug for a two-stroke internal combustion engine of a gasoline streamer is installed to replace the old part that is out of order

After starting, the engine may stall if the carburetor is incorrectly tuned or misaligned. What are the signs that you can understand that the reason really lies in this? It is very simple, by the vibrations that will be clearly felt when the mower is running. You can adjust the fuel supply with your own hands by following everything that is written in the operating instructions for the tool.

The engine may stall due to a clogged fuel valve. The cause is eliminated by cleaning it. If the brushcutter starts up and then suddenly stalls, it means that the fuel supply to the carburetor is difficult. Loosen the carburetor valves to ensure that the correct amount of fuel can flow to it.

Excessive air intake can also stall the engine. Increase engine revs to allow air bubbles to escape faster from the unit's fuel system. Also, be sure to check the integrity of the fuel intake hose. If you find mechanical damage (cracks, punctures, etc.), replace the part.

During the period of operation of petrol cutters, monitor the condition of the engine cooling system. The channels in the starter housing and the cylinder fins must always be clean. If you ignore this requirement and continue to operate the brushcutter, you can damage the engine due to overheating.

Competent care of the gasoline scythe during operation allows you to use it for several seasons in a row without major repairs

Allow engine to cool before cleaning. Take a soft bristled brush and clean the outside of the dirt. Cleaning of plastic parts is carried out with solvents, including kerosene, or special detergents.

At the end of the summer season, the brushcutter must be prepared for long-term storage. For this, the fuel mixture is drained from the tank. The engine is then started to use up fuel residues in the carburetor. The entire tool is well cleaned of contamination and goes to "hibernation".

As you can see, it is possible to repair the faults of a household petrol cutter on your own. It is worth contacting service departments in case of serious breakdowns. In this case, the cost of repairs should be correlated with the price of a new petrol cutter. It may be more appropriate to buy a new instrument.
