Pre-Use Guidelines for YT27 Rock DrillsDefining Excellence: What is a Pneumatic Rock Drill?
2. Prioritize safety by tapping the roof near the working face to assess for any loose or live rocks. Conduct necessary treatments to secure the area and prevent hazards.
3. Achieve precision by leveling the working surface at the flat shell hole location ahead of time. This proactive step prevents slippage or undesired displacement of the shell hole during rock drilling.
4. Commit to efficient and safe practices by strictly avoiding dry hole drilling. Always initiate wet rock drilling by activating the water flow first, followed by the wind. When stopping, turn off the wind first, then the water. Begin with a low-speed operation when opening the hole, then proceed to full speed once a certain depth is achieved.
5. For safety reasons, drillers must refrain from wearing gloves during drilling operations.
6. Employ vigilant, safety-conscious techniques when using the air leg to drill. Maintain an appropriate posture and stance, avoiding the use of body weight for pressure. Never position yourself in front of the rock drill or the working brazing rod to prevent injury.
7. If unusual sounds or irregular water discharge occur during rock drilling, halt operations immediately. Investigate and resolve the issue before resuming to ensure smooth and safe drilling.
8. Exercise caution when withdrawing the rock drill or replacing the brazing rod. Operate the rock drill slowly and remain attentive to the position of the brazing rod for optimal safety.
