Preparation before starting
1. The new Reaming Bit is coated with anti-rust oil with high viscosity, which must be disassembled and cleaned before use. When reinstalling, lubricate the surface of each moving part. After installation, connect the Reaming Bit to the compressed air pipeline, run with a small wind, and check whether it is operating normally.
2. Fill the automatic lubricator with lubricating oil, please use the oil according to the instructions. The lubricating oil container should be clean and covered to prevent rock dust and dirt from entering the lubricator.
3. Check the wind pressure and water pressure at the work place frequently. Too high wind pressure will accelerate the damage of mechanical parts, and too low will reduce the drilling efficiency. If the water pressure is too high, water will pour into the machine to destroy lubrication, reduce the efficiency of Reaming Bit and rust mechanical parts
4. Check whether the drill rods and drill bits used meet the quality requirements. Unqualified drill rods and drill bits are prohibited from being used.
5. When the duct is connected to the Reaming Bit, the air should be vented to blow out the impurities in the duct. The water pipe must be cleaned of impurities at the joint. The air pipe and the water pipe must be tightened to prevent injury.
6. Insert the drill tail into the Reaming Bit head, and turn the drill clockwise forcefully. If it does not turn, it means there is a jam in the machine, which should be dealt with in time.
7. Tighten the connecting bolts with Extension Drilling Tools, check the operation of the propeller, and start working only when it operates normally.
