Essential Guidelines for Utilizing YT27 Rock Drills:Understanding the Pneumatic Rock Drill: A Revolutionary Tool for Efficient Mining
2. Safeguard your workspace by thoroughly tapping the roof area near the working face. This inspection is crucial to identify and address any potential hazards posed by loose or live rocks, ensuring a safe and stable environment for your drilling efforts.
3. Prepare the flat shell hole location meticulously by flattening it in advance. This crucial step prevents any slippage or displacement during rock drilling, ensuring precision and stability in your operations.
4. Adhere to the strict prohibition of dry eye drilling. Embrace the practice of wet rock drilling by initiating water flow before activating wind power during operations. Similarly, cease wind flow before water when stopping. Begin drilling at a low speed, gradually escalating to full speed once a certain depth is achieved.
5. For safety reasons, drill operators must refrain from wearing gloves while engaged in drilling activities, ensuring uninhibited dexterity and control.
6. When employing the air leg for drilling, maintain caution regarding your stance and positioning. Avoid exerting pressure with your body and never stand in front of the rock drill beneath the working brazing rod to prevent injury from potential breakage.
7. Should any abnormal sounds or irregular water discharge occur during rock drilling, immediately halt machine operation. Conduct a thorough inspection to determine and rectify the cause before proceeding, ensuring continued safe and efficient drilling.
8. In the event of retracting the rock drill or substituting the brazing rod, operate the rock drill at a reduced speed while diligently monitoring the position of the rock drill braze, ensuring seamless transitions and optimal safety.
