YT27 Rock Drills: Essential Pre-Use GuidelinesUnderstanding the Pneumatic Rock Drill
2. Conduct a thorough inspection of the roof adjacent to the work area. It is crucial to identify and address any presence of loose or unstable rocks on the roof and the surrounding second gang, implementing necessary safety measures.
3. Ensure the work surface at the planned shell hole location is evenly leveled beforehand to prevent any risk of slippage or displacement during the rock drilling process.
4. It is imperative to avoid dry drilling at all costs. Commit to the practice of wet rock drilling by initiating the water flow prior to activating the air. Conversely, shut off the air before the water upon completion. Begin the drilling process at a low speed, transitioning to full speed only after penetrating a satisfactory depth.
5. Under no circumstances should operators wear gloves while drilling to ensure maximum safety and control.
6. When employing the air leg to assist in drilling, maintain a proper stance and positioning. Avoid applying body pressure or standing directly in front of the drill and brazing rod to mitigate the risk of injury from potential breakages.
7. Should any irregular sounds or abnormal water discharges occur during drilling, immediately cease operations to investigate and resolve the issue before resuming work.
8. When retracting the rock drill or substituting the brazing rod, operate the rock drill at a reduced speed. Pay close attention to the brazing rod's position to ensure safe and efficient handling.
