Due to the harsh working environment of the tiller, maintenance is particularly important. During the work of the tiller, due to the friction and vibration of the parts and components, and the invasion of oil, mud and water, the parts are inevitably worn out; the connection is loose and corroded and aging. As a result, the technical condition of the tiller has deteriorated, the power has decreased, the fuel consumption has increased, the wear has accelerated, and the failures have continued to appear. In order to prevent the occurrence of the above situation, it is necessary to strictly implement the maintenance system of "prevention is more important than cure, and care is more important than repair".
Maintenance must be carried out in strict accordance with the maintenance cycle and content. Liu Yongzhong of Jinzhu Village in the sub-township reported that his machine was weak, burning oil, difficult to start, disassembly and inspection: the oil in the engine gearbox was muddy, and it was difficult to lubricate; all the ventilation holes of the engine's heat sink were blocked, and the heat dissipation effect was poor; The piston is severely worn, and the power is insufficient. Typical failure caused by insufficient maintenance.
