YT27 rock drills before use:What is a pneumatic rock drill?
2. Safety first! Before proceeding, inspect the roof near the working area. Tap gently to identify any unstable rocks or debris that could pose a risk. Ensure that both the roof and second gang area are secure to prevent unforeseen accidents.
3. To guarantee precision and safety in drilling, ensure the working surface is flat by pre-flattening the shell hole location. This precaution helps avoid slippage or displacement of the drill.
4. Embrace the right technique by avoiding dry drilling. Always engage in wet rock drilling by activating the water flow before air. When stopping, reverse this order by turning off the air first, and then the water. Start your drill at a low speed to prevent damage and gradually increase speed as you reach greater depths.
5. For maximum safety, drillers must operate without gloves to ensure a better grip and control during drilling.
6. Maintain proper ergonomics when using an air leg for drilling. Avoid using your body weight for pressure, and never stand directly in front of the rock drill while it’s operational, as this could lead to serious injury from a broken brazing rod.
7. Pay close attention to the sound and water discharge during drilling. If any abnormality is detected, halt operations immediately to inspect and rectify the issue, ensuring a safe continuation of the task.
8. When retracting the rock drill or changing the brazing rod, operate at a reduced speed. Carefully monitor the positioning of the brazing rod to ensure safe and efficient handling.
