Preparation Protocol Before Utilizing the Rock Drill:
1. Before beginning, verify that every component—be it the rock drill, the supporting bracket, or the rock drill cart—is intact, meticulously lubricated, and ready for action. Ensure all air and water conduits are clear and that all connection joints are secure and tightly fitted.
2. Conduct a thorough inspection of the roof area near the drilling site for any loose or potentially hazardous rocks. Address all safety concerns prior to commencing operations.
3. Confirm that the working surface is perfectly leveled and stable to ensure precision while drilling and to prevent any risks of slippage or displacement.
4. It is crucial to employ water as a coolant during drilling to prevent dry drilling conditions. Initiate the process with water circulation, followed by wind. When halting, reverse this sequence, beginning with wind cessation. Start operations at a low speed, shifting to full speed only after attaining a certain depth.
5. Operators must refrain from wearing gloves during operation to maintain full control and sensitivity.
6. Maintain a strategic and secure posture while handling the air leg. Avoid using body weight for pressurization. Position yourself safely to avoid potential injuries from broken brazing rods, and never stand directly in front of the rock drill.
7. Should you encounter unusual noises or experience unexpected water discharge, promptly halt operations, conduct a thorough inspection, and address any issues before proceeding.
8. Exercise caution when retracting the rock drill or changing the brazing rod. Operate at a reduced speed and remain vigilant about the brazing rod's position to ensure safety.
