Maintenance
Maintenance
Lubricate the machine regularly with air tool oil.
Before longer standstills clean and lubricate the
machine. When putting the machine into operation
again, flush through with paraffin or a similar fluid.
Immediately after flushing thoroughly oil the ma-
chine with air tool oil.
The machine should be dismantled for overhauling
and cleaning at regular intervals after 500 running
hours but at least once every six months.
The use of other than genuine Atlas Copco replace-
ment parts may result in decreased tool performance
and increased maintenance and may, at the option
of the company, invalidate all warranties.
Cleaning
At 100 hour operating intervals or earlier if operation
becomes sluggish or the machine shows sign of
sticking, flush through with paraffin or a similar
material. Immediately after flushing thoroughly oil
the machine with air tool oil.
The strainer inside the inlet adapter (b) should be
cleaned frequently to prevent choking with resultant
decrease in capacity.
Dismantling
All threads are right hand.
• Remove ring (35).
• Clamp the cylinder (20) firmly in a vice and un-
screw the handle (1).
• Back off the outer cover (27) – if necessary heat
locally the front part of the cover so as to loosen
the locking compund bond on the threads.
• Remove, clean and inspect all parts – see spare
parts list illustration.
Assembly
• Replace all O-rings and worn parts.
• Ensure all parts are clean and have a film of air
tool oil lubrication.
• Clamp the cylinder (20) vertically in a vice. Insert
piston (24) and parts (25,26). Fit O-rings (28 and
30). Apply a few drops of Loctite 270 locking
compund to the threads and tighten the outer
cover (27), recommended tightening torque 70
Nm.
• Lubricate O-ring (30) and the threads of handle
(1). Fit parts (31-33) and the percussive mechan-
ism (P). Tighten casing (34), recommended torque
approx. 30 Nm. Fit the ring (35).
