Many users trimmers do not pay much attention to the maintenance of their tools. In particular, this applies to such a scythe assembly as a gearbox. The operation of the gearbox is associated with heat.
With long-term operation of lawn mowers, regular overheating of the gearbox occurs, which leads to its breakdown. Damage to the gearbox leads to the fact that the tool is unusable and needs to be repaired.
Repairing a gearbox is an expensive undertaking, so it is recommended not to bring the tool to such a state. The main reason for overheating of the gearbox and its failure is the lack of lubrication in it.
The article tells how to properly lubricate the trimmer gearbox in order to avoid damage to it.
