YT27 Rock Drills Before Use: Essential Guidelines for Optimal PerformanceWhat is a Pneumatic Rock Drill? An In-Depth Understanding
2. Conduct a thorough examination of the roof near the working face by knocking, to detect any loose or unstable rocks. Address any identified issues promptly to secure the area.
3. Ensure the working surface for flat shell hole location is pounded flat ahead of time. This precaution is vital to prevent slippage or displacement of the shell hole during rock drilling.
4. Adherence to wet rock drilling is mandatory; refrain from drilling dry eyes. When operating, always start the water flow before the wind, and upon cessation, stop the wind before the water. Begin hole drilling at a reduced speed, progressing to full speed only after reaching a certain depth.
5. Safety protocol dictates that drillers must not wear gloves during drilling to ensure maximum control and dexterity.
6. While utilizing the air leg for drilling, maintain correct posture and position. Never apply body pressure or stand in front of the rock drill under the work brazing rod to avert potential injury from broken brazing.
7. Should there be any unusual sounds or irregular water discharge during rock drilling, immediately halt operations. Investigate and rectify the issue before resuming.
8. When retracting the rock drill or swapping the brazing rod, allow the rock drill to operate slowly. Pay close attention to the positioning of the rock drill braze to ensure safety.
