YT27 rock drills before use:What is a pneumatic rock drill?
2. Vigilantly inspect the roof near the working face to detect any live or loose rocks. Implement essential safety measures to secure the working area before proceeding.
3. Ensure the designated working surface for the flat shell hole is pre-flattened before drilling. This precaution is crucial to avert any slippage or misalignment of the shell hole during rock drilling activities.
4. Adherence to wet rock drilling techniques is paramount; it is strictly prohibited to conduct dry drilling. Begin by activating the water flow followed by the wind when operating. Conversely, when ceasing operations, halt the wind flow prior to stopping the water. Initiate drilling at a low speed, progressing to full speed as the hole reaches the desired depth.
5. For safety reasons, drillers must refrain from wearing gloves during the drilling process.
6. When employing the air leg for hole drilling, maintain a vigilant focus on your stance and positioning. Refrain from using your body as leverage for pressure, and never stand in front of the rock drill during operation to prevent injuries from potential tool failure.
7. If any unusual noises or water discharges occur during rock drilling, immediately cease operations. Conduct a thorough inspection to diagnose and resolve the issue before safely resuming the task.
8. When retracting the rock drill or replacing the brazing rod, allow the rock drill to operate at a slow pace. Remain aware of the positioning of the rock drill bit to ensure safety and precision.
