Preparations before using the YT27 Pneumatic Rock Drill:What exactly is a pneumatic rock drill?
2. Carry out a precise inspection of the roof near your designated working area. This entails assessing for any loose or precarious rocks, both on the roof and the secondary gang near the working face. Implement the necessary safety measures to secure these areas.
3. Prepare the working surface by ensuring that the flat shell hole location is adequately flattened in advance. This step is crucial to preventing any slippage or displacement of the shell hole during the drilling process.
4. Adhere strictly to the prohibition of dry eye drilling by committing to wet rock drilling practices. Begin each operation by turning on the water flow before activating the air. Conversely, upon stopping, deactivate the air before the water. Initiate drilling at a low speed, and once a certain depth is achieved, proceed to drill at full speed.
5. It is imperative that drillers refrain from wearing gloves during the drilling process.
6. When employing an air leg to assist with hole drilling, be vigilant about your standing posture and positioning. Avoid using your body weight to apply pressure, and never stand directly in front of the rock drill while the brazing rod is in operation, to prevent injury from potential rod breakage.
7. Should any irregular sounds or unusual water discharge occur during drilling, it is essential to halt the machine immediately. Conduct a thorough inspection to diagnose and rectify the issue before resuming operations.
8. When retracting the rock drill or exchanging the brazing rod, allow the rock drill to run at a reduced speed while carefully monitoring the brazing rod's position to ensure safety.
