YT27 Rock Drills: Essential Pre-Use GuidelinesUnderstanding Pneumatic Rock Drills
2. Conduct a thorough examination of the roof near the working face, checking for loose or live rocks that may linger ominously. Perform necessary treatments to secure the site and ensure safety.
3. Prepare the working surface with precision; flatten the shell hole location in advance to prevent any slippage or displacement during rock drilling, ensuring a steady and precise operation.
4. Adhere strictly to the protocol of wet rock drilling. Before commencing, turn on the water, followed by the wind; and when halting, reverse the order to prevent dry drilling and its associated risks. Begin with a gentle, low-speed drill to initiate the hole, advancing to full speed only after reaching a certain depth.
5. For your safety, refrain from wearing gloves during the drilling process.
6. While utilizing the air leg for hole drilling, maintain an attentive stance and positioning. Avoid using your body to exert pressure and never stand directly in front of the rock drill with a working brazing rod, as this could result in injury from unexpected breakage.
7. Should you encounter unusual noises or irregular water discharge during drilling, halt operations immediately, conduct a thorough inspection, and resolve any issues before proceeding with the drilling task.
8. When retracting the rock drill or switching out the brazing rod, allow the rock drill to run at a gentle pace and be mindful of the brazing rod's position to ensure a smooth transition.
