Before Using the Rock Drill: Key Preparations for Optimal Performance and Safety
1. Conduct a thorough inspection to ensure all components, including the rock drill, bracket, and any associated carts, are intact and possess optimal lubrication. Verify unobstructed wind and water pathways and ensure all connection joints are tightly secured.
2. Examine the roof near the working area for any precarious or loose rock formations. Address and resolve these issues to ensure a safe environment before commencing operations.
3. Confirm that the drilling surface is completely level to prevent any unwanted slippage or displacement during the drilling process.
4. Always commence with water to avoid the hazards of dry drilling. Initiate operations with water, followed by wind, ensuring the cessation process is reversed. Start drilling at a low speed, transitioning to full speed only after achieving a sufficient initial depth.
5. Operators must refrain from wearing gloves while maneuvering the drill, ensuring safety and precision.
6. Maintain proper posture and positioning when utilizing the air leg. Avoid applying pressure with your body and steer clear of standing directly in front of the rock drill to prevent injuries from potential brazing rod breakage.
7. Should you encounter any abnormal sounds or unexpected water discharges, halt operations immediately. Conduct a thorough inspection and rectify any issues prior to resuming activity.
8. Exercise caution when retracting the rock drill or replacing the brazing rod. Operate slowly, remaining mindful of the brazing rod's position to ensure safe handling and operation.
