Operation & maintenance:
Besides observance of the general safety precautions for rock
drilling operations, particular attention should be paid to the
following:
The rifle nut and the piston are matched with left-handed threads.
Be careful with the direction of rotation during assembling and
disassembling.
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.
