1. Newly-bought rock drills are generally coated with high-viscosity antirust grease, and must be disassembled before use. When reassembling, all moving parts should be lubricated. After installation, connect the rock drill to the compressed air pipeline, turn on a small wind and check whether it runs normally.
2. Inject lubricating oil into the automatic oiler. Common lubricating oils are 20, 30 and 40 engine oils. The container containing lubricating oil should be cleaned and capped to prevent rock powder and dust from entering the oiler.
3. Check the air pressure and water pressure in the workplace. The wind pressure is 0.4-0.6MPa, too high wind pressure will accelerate the damage of mechanical parts; If it is too low, the drilling efficiency will be reduced and the mechanical parts will be corroded. The water pressure is generally 0.2-0.3MPa. If the water pressure is too high, water will be pumped into the machine to destroy lubrication, reduce the efficiency of the rock drill and corrode mechanical parts. If it is too low, the washing effect will be poor.
