YT27 rock drills before use:What is a pneumatic rock drill?

1,Check the integrity and rotation of all parts (including rock drill, bracket, or rock drill cart) before drilling, fill necessary lubricant, and check whether the wind and waterways are smooth and whether the connection joints are firm.

2,Knock on the roof near the working face, i.e. check whether there are live rocks and loose rocks on the roof and second gang near the working face, and make necessary treatment.

3, the working surface of the flat shell hole location, is to be pounded flat in advance before allowing rock drilling, to prevent slippage or shell hole displacement.

4. It is strictly forbidden to drill dry eyes, and we should insist on wet rock drilling, turn on the water first and then the wind when operating, and turn off the wind and then the water when stopping drilling. When opening the hole, run at low speed first, and then drill at full speed after drilling to a certain depth.

5,No gloves are allowed to be worn by the drillers when drilling.

6,When using the air leg to drill the hole, pay attention to the standing posture and position, never rely on the body to pressurize, let alone stand in front of the rock drill under the work brazing rod, to prevent injury from broken brazing.

7,If abnormal sound and abnormal water discharge are found in rock drilling, stop the machine for inspection and find out the reason and eliminate it before continuing to drill.

8,When withdrawing from the rock drill or replacing the brazing rod, the rock drill can run slowly and pay attention to the position of the rock drill braze.
