Before Using the YT27 Rock Drills: Essential PreparationsDiscover the Power of a Pneumatic Rock Drill: A Comprehensive Overview
2. Conduct a thorough inspection by tapping on the roof near the working face. This step checks for any live or loose rocks on the roof and the second gang near the working face, allowing for immediate and necessary treatment.
3. Ensure the flat shell hole location is meticulously leveled before initiating rock drilling. This pre-emptive action prevents undesirable slippage or displacement of the shell hole during operations.
4. Strictly prohibit dry-eye drilling! Always adhere to wet rock drilling protocols. Begin by activating the water flow, followed by the wind. Conversely, turn off the wind first, and then the water when ceasing operations. Start drilling at a low speed, then transition to full speed once a desired depth is achieved.
5. Safety First: Drillers must refrain from wearing gloves while drilling to ensure maximum control and maneuverability.
6. When employing an air leg for drilling, maintain proper standing posture and position. Never pressurize with the body and avoid standing in front of the rock drill near the work brazing rod—this precaution helps prevent injuries from potential breakage.
7. Should any abnormal sounds or irregular water discharge occur during rock drilling, immediately cease operations for inspection. Identify and rectify the cause before resuming to ensure safe and efficient drilling.
8. During the withdrawal of the rock drill or when replacing the brazing rod, operate the rock drill at a slow pace. Always be mindful of the precise positioning of the rock drill braze to ensure seamless transitions.
