Preparation Steps Prior to Using the Rock Drill:
1. Begin by thoroughly inspecting all components, including the rock drill, its bracket, or rock drill cart. Ensure every part is intact and adequately lubricated. Verify the seamless flow of air and water channels, and make sure all connection joints are securely fastened.
2. Conduct a meticulous inspection of the area above the working surface for any live or unsecured rocks. Address these issues meticulously before commencing operations to ensure safety.
3. Confirm that the working surface is perfectly flat before beginning the drilling process to prevent any risks of slippage or unintended displacement.
4. Always incorporate water while drilling to avoid the hazards of dry drilling. Initiate the process with water followed by wind. When stopping, reverse this order. Begin drilling at a low speed, accelerating to full speed only once you've reached a sufficient depth.
5. Operators must refrain from wearing gloves during the use of the drill for safety reasons.
6. Mindfully observe your posture and position while operating the air leg. Avoid exerting pressure with your body and never stand directly in front of the drill to minimize the risk of injury from flying brazing rod fragments.
7. If the machine emits unusual sounds or water discharges unexpectedly, halt operations immediately, conduct a thorough inspection, and resolve any detected issues before proceeding.
8. When retracting the rock drill or switching brazing rods, operate the drill slowly and maintain awareness of the brazing rod's position to ensure optimal safety.
