Preparation Tips for Using YT27 Rock Drills: Ensure Optimal Performance and SafetyUnveiling the Pneumatic Rock Drill: What Exactly Is It?
2. Conduct a thorough evaluation of the roof near the working face. Examine for any loose or potentially unstable rocks and apply the necessary treatments to stabilize them, ensuring a safe working environment.
3. The site of the flat shell hole must be meticulously prepared and leveled before rock drilling commences. This precautionary measure prevents unwanted slippage or displacement of the shell hole during operations.
4. Adhere strictly to wet rock drilling practices. Initiate operations by turning on the water supply before activating the wind. When halting drilling, reverse this sequence. Begin drilling at a low speed, gradually increasing to full speed once a certain depth is achieved. This method ensures optimal performance and safety.
5. For safety reasons, drillers must refrain from wearing gloves during the drilling process, minimizing potential hazards.
6. When utilizing the air leg for drilling, maintain a vigilant posture and position. Avoid using body weight to apply pressure. Never stand directly in front of the rock drill or under the brazing rod during operation to prevent injury from any possible breakage.
7. Should any unusual noises or irregular water discharges occur, cease operations immediately. Inspect the machinery thoroughly to identify and resolve the issue before resuming drilling.
8. When retracting the rock drill or exchanging the brazing rod, operate the rock drill at a reduced speed. Pay close attention to the position of the rock drill braze to ensure precise and safe handling.
