Gas trimmer - malfunctions and their elimination. Petrol trimmer received wide use due to low cost and ease of use. It is in demand for the care of plots and among summer residents and owners of private houses. Since this tool is used only in warm season , before starting operation, the tool must be checked and prepared - lubricate the rubbing parts, fill in the fuel mixture, put the cutting headset. In the operation of any equipment, failures and malfunctions occur, in order to fix them yourself, you need to understand the device of your unit and the principle of its operation. To do this, first of all, you need to study the operating instructions, which the seller must attach to the equipment upon sale. Briefly about the device of the gas trimmer. A metal tubular rod is attached to the gearbox of a two-stroke internal combustion engine. A shaft passes inside the bar, which transmits torque from the gasoline engine to the cutting mechanism. The cutting attachment can rotate at 10,000 to 13,000 rpm. There must be holes in the gearbox housing through which lubrication is performed. For ease of use, trimmers are equipped with a belt and shoulder strap. Mowing takes place directly with the cutting headset, which is located in the trimmer head, it is the most exposed to wear. To replace the line, you must either wind a new one on the bobbin, or install another spool with already wound line. A handle is attached to the bar, on which the control levers are located. The cutting mechanism is protected by a special casing. Two-stroke lawn mowers are refueled with a mixture of gasoline and oil, which is poured into the fuel tank. In four-stroke - gasoline is poured into the tank, and oil is poured into the crankcase. Engine won't start. If your gas trimmer does not want to start in any way, the first thing to check is the presence of fuel and its quality. Poor quality gasoline can lead to failure of the piston group. And then you are guaranteed an expensive repair. It is also important to properly prepare the fuel mixture. The proportions of gasoline and oil are always indicated in the manual. The mixture must be fresh, as it loses its properties during storage. A common reason that the scythe does not start is a dirty fuel filter. In this case, it is necessary to check the condition of the filter and, if necessary, replace it. Do not operate the tool without a fuel filter. If the engine is running bad, you should also check the air filter. When contaminated, the part is removed, washed in gasoline and put in place. If this is not possible, you can also rinse in water with detergent, dry, moisten with oil, wring out and install in place. If all of the above has already been tried, and the engine still does not start, then try adjusting its speed to Idling by tightening the carburetor screw. Quick start. Place the tool so that the air filter is at the top. With this arrangement, the trimmer ensures that the fuel mixture hits exactly at the bottom of the carburetor. If you remove the air filter before starting and pour a few drops of the fuel mixture directly into the carburetor, then replace the filter and cap, then most likely the engine will start on the first try. If this does not help, the problem may be in the spark plug. Then you need to unscrew it, check its performance and dry the combustion chamber. A broken spark plug can easily be replaced with a new one. But, if the candle is in order, the filters are clean, the fuel is fresh, and the scythe still does not start, then you can try to close the air damper, pull the starter once, then open and pull the starter handle a few more times. This procedure is repeated three to five times. With careless handling and excessive zeal, you can disable the starter. If the cable breaks or the handle breaks, then repairs can be made independently, in other cases it is necessary to replace the entire starter. Replacing the spark plug. Replacement must be done when the engine is already cold. To do this, disconnect the wire from the candle and unscrew it. The candle needs to be replaced if it is heavily soiled or has cracks in the body. Please note that the gap between the electrodes should be 0.6 mm. A new spark plug is inserted into the engine and tightened with a wrench, then a high-voltage wire is connected. Engine stalls after starting. Most likely the carburetor is incorrectly adjusted, or its misalignment has occurred. The fact that the reason for this can be understood from the vibration during operation. You can adjust the carburetor yourself by following the instruction manual. The trimmer can also stall if the fuel valve is clogged. Then it just clears out. If the engine stalls abruptly, the fuel supply to the carburetor may be difficult. You need to loosen the carburetor valves. Or there is excess air in the carburetor, here you need to increase engine speed so that excess air leaves the fuel system faster. You also need to check the integrity of the fuel intake hose. In case of detection of mechanical damage (cracks, punctures, etc.), it must be replaced. Cleaning and storage. The cylinder fins and channels in the gas trimmer housing must be clean, otherwise it is fraught with engine overheating. Allow the engine to cool before cleaning. The outer surface is cleaned with a brush. Plastic parts can be cleaned with kerosene and other solvents or by special means. For long-term storage, the entire mixture is drained from the fuel tank, then the engine is started to work out the remaining fuel in the carburetor. Keep the tool only in a clean state. If it was not possible to make repairs with your own hands, it is worth evaluating what is more expedient, contact the service or purchase a new trimmer.

Like any technology, they are subject to various breakdowns. Often, at the beginning of the summer season, the owners of such a tool complain that the trimmer does not start, and it takes a long time to look for the cause of the malfunction.

For those who have recently purchased a trimmer and are still on the “you” with this technique, there will be useful information about why the trimmer does not start and what to do in this case. So let's find out what could be causing this.

Gas trimmer won't start - 10 possible reasons

Before attempting to adjust the operation of the tool yourself, carefully read the instruction manual for its operation. Perhaps the information contained in it will prompt you to one or another thought. Otherwise, you will have to look for the cause of the malfunction by the selection method. It may be one of the following:

1. The toggle switch on the boom is not set to the “On” position. This is one of the elementary steps, but sometimes beginners forget to turn on the tool before launching it.
2. Such errors include the lack of fuel in the tank. If the fuel runs out, and you forgot about it, just fill the tank (usually located near the engine) with AI-92 gasoline.
3. Missing, wrong mixture or wrong proportion of engine oil. Ideally, no more than 50 g of oil should be added regularly. This will act as extra lubrication and will keep your trimmer motor running. Also keep in mind that oil is different types("synthetics", "semi-synthetics", "mineral water") - they all affect the operation of the mechanism in different ways.
4. If the mower-trimmer does not start after winter, drain the remaining fuel in the gas tank and replace it with fresh fuel. This is especially true for small, low-power trimmers with small motors that are sensitive to low-quality mixtures. In addition, during the winter, sediment may form at the bottom of the gas tank, due to which there are problems with the operation of the device.
5. Excessive pumping of fuel can also be one of the reasons that the trimmer stalls and does not start. When the air damper is closed, the spark plug is filled with fuel. It should be unscrewed and dried, and then inserted into its place and try to start the engine while holding the gas trigger. It is advisable to check it before that for the presence of a spark between the electrodes. If there is no spark, the spark plug should be replaced.
6. Filter problems. If your trimmer does not start well, remove the air filter and run the tool without it. If everything worked out, the filter should be replaced with a new one. As an option, thoroughly clean and blow out the old one, but the replacement will still have to be done sooner or later.
7. Trimmer stalled and won't start? Try to clean the so-called breather - an element designed to equalize the pressure in the gas tank. Cleaning can be done with a regular long needle. A clogged breather is often the cause of a malfunction.
8. Knives removed from the machine - some models will not work under this condition.
9. Violation of tightness. You can check this with a manometer. If the pressure starts to drop, you should determine which of the parts of the carburetor is faulty. Most often, the carburetor gasket wears out.
10. Sometimes, after a long period of operation, you may notice that the trimmer has overheated and will not start. First, you should know that you should definitely take breaks. The amount of continuous operation time recommended for this model should be specified in the instructions. Also, the problem of overheating may lie in a faulty ignition coil or in the system air cooling which prevents overheating.

If none of these actions worked, you should contact a repair shop or service center.
