When connecting the drill to the air and water supplies, check carefully if the wire clips (32)(36) are entirely and correctly set in the respective semi-circular grooves of the backhead (30). Check frequently the wear on the clips and timely replace the worn-out or broken one or broken one to avoid the shooting out of the swivel(55)(58) or the connector when the air or water is on.
Before operation, fill the line oiler with lubrication oil up to the required level. The drill should not be run without proper lubrication (recommended lube oil N46 and N22, Chinese National Standard GB443-84).
After operation, first turn off the water, lightly run the drill for a few seconds, blow out the residual water drops to prevent the parts from being corroded.
If the drill is often used, should maintenance it regularly to ensure the inside parts cleaning. Especially pay attention to change the worn parts and lose efficient parts.
