(6)During maintenance, the tools and hands should be kept clean and wiped with high-grade toilet paper as much as possible, and the spare parts should be cleaned with silk cloth.
(7) All the seals involved in small, medium and large repairs should be replaced to ensure continuous operation time after repair. The loss of shutdown of hydraulic drifters is several to a hundred times higher than that of replacement of seals.
(8) Hydraulic drifters have strict requirements on the working fluid. After a certain period of work, the working fluid will change, which will reduce or lose its good viscosity-temperature characteristics.Poor lubrication performance will greatly reduce its wear resistance. Early damage to the parts will reduce the rust resistance and strengthen the corrosion. The service life of the rock drill will be reduced, resulting in early scrapping. Therefore, the working fluid must be replaced regularly as required.If emulsification is found within the prescribed period, the working fluidmust be replaced immediately.
(9) In order to ensure the service life of the seals in the water system, the hydraulic drifter must be turned on after the water is supplied, and can not be turned on without water, otherwise the sealing lip of the seals will be burned to lose water sealing performance.
Seals
(10) Invalid percussionis absolutely forbidden before the water system and the shank are installed. The consequence of the invalid percussionis that the impact cylinder will be scrapped, and minor damage must be sent to the factory for overhaul.
