YT27 Rock Drills Before Use: Essential Preparation GuideWhat is a Pneumatic Rock Drill?
2. Thoroughly examine the roof near the working face by tapping to detect any loose or unstable rocks and address them promptly to ensure safety and stability.
3. Before commencing rock drilling, the flat shell hole location must be evenly leveled in advance to prevent any slippage or displacement during the drilling process.
4. Adhere strictly to wet rock drilling techniques; it is imperative to avoid dry drilling. Initiate water flow before air when starting, and cease air flow before water upon stopping. Begin drilling at low speed to establish initial depth before proceeding at full speed.
5. Drillers must refrain from wearing gloves while operating the drill to ensure optimal control and safety.
6. When employing the air leg for hole drilling, maintain a correct standing posture and position. Avoid using body weight to apply pressure and never position yourself in front of the rock drill's brazing rod to prevent injury from potential breakage.
7. Should any abnormal sounds or unusual water discharge be detected during rock drilling, immediately halt operations to inspect and resolve the issue before resuming.
8. When retracting the rock drill or replacing the brazing rod, operate the rock drill at a slow pace and remain vigilant of the brazing rod's position for safety.
