Pre-Operational Checklist for the Rock Drill:
1. Verify that every component, encompassing the rock drill, its supporting bracket, or drill cart, is not only intact but also thoroughly lubricated. Confirm that both wind and water pathways are unobstructed and that all connection points are securely fastened.
2. Conduct a thorough inspection of the roof near the intended working area to identify and mitigate any risks posed by live or loose rocks before commencing operations.
3. Guarantee that the working surface is perfectly even to prevent any instances of slippage or unintended movement during the drilling process.
4. Always incorporate water into your drilling process to avoid the dangers of dry drilling. Initiate the operation by activating the water flow, followed by the wind. Upon cessation, reverse this sequence. Start drilling at a low speed and transition to full speed as the drill penetrates deeper.
5. It is imperative that drillers refrain from wearing gloves while operating the equipment to maintain optimal control and safety.
6. Maintain conscious awareness of your posture and positioning while utilizing the air leg. Refrain from exerting pressure with your body and avoid positioning yourself in front of the drill to prevent injury from any potential brazing rod breakage.
7. In the event of any unusual noises or unexpected water discharge, immediately halt the machine, conduct a thorough inspection, and rectify the problem before continuing with operations.
8. When retracting the rock drill or exchanging the brazing rod, proceed with caution and operate at a reduced speed, remaining mindful of the brazing rod's positioning to ensure safety and precision.
