(6) Parts, tools and hands should be kept clean during maintenance. They should be wiped with high-grade toilet paper as much as possible, and silk cloth should be used for cleaning parts.
(7) All the seals involved in small, medium and overhaul shall be replaced to ensure continuous operation time after one maintenance. The loss of a rock drill is several times to a hundred times higher than that of a seal..
(8) Hydraulic rock drill has strict requirements for working fluid. When working for a certain period of time, the working fluid changes, which will reduce or lose the good viscosity-temperature characteristics, and the poor lubrication performance will greatly reduce the abrasion resistance., Causing early damage to parts, but also reduce rust resistance, and strengthen the corrosion. This reduces the service life of the rock drill, resulting in early scrap. Therefore, the working fluid must be replaced regularly according to the regulations, and if emulsification is found within the specified period, it must be replaced immediately.
(9) In order to ensure the service life of the water seal of the water supply system, it is necessary to start the machine after boiling water, and it is not allowed to start the machine without water supply, otherwise it will cause the sealing lip of the water seal to burn and lose the water sealing performance.
Water seal
(10) It is absolutely not allowed to let the rock drill hit empty before the water supply device and drill tail are installed. The consequence of empty hitting is that the impact cylinder body will be scrapped and minor damage will be sent to the factory for overhaul.
