The machine can only work properly with high-quality fuel. Gasoline brand must correspond to engine needs. If the device will run on low-quality fuel, it is fraught with frequent malfunctions of the grass trimmer. If this problem is not solved in time, the cylinder-piston system may eventually break down. The cost of repairing such a machine often exceeds the price of the machine itself.

The lawnmower must not be filled with an improperly prepared fuel mixture. In the instruction manual of the device manufacturers necessarily indicate the exact proportions in which high-quality gasoline and mineral oil should be combined. It is not recommended to prepare a mixture in large quantities, because during prolonged storage loss of certain properties inevitably occurs. If the gasoline mower does not start, then you should carefully drain the old fuel to be able to use a freshly prepared fuel mixture.

Many users of mowers noticed that after a while after the start of the device, it begins to vibrate strongly. Some trimmers, mostly more expensive models, have an anti-vibration system in the form of shock absorbers placed between the engine and the boom. But in some cases, even this is not enough to cope with the strong vibrations. The reason why the trimmer gets a lot of vibration can be due to little or no lubrication on the hard or flexible shaft inside the boom of the machine.
