When taking a break
♦ Lay down the rock drill on a stone, wooden plank
or similar object, so as to prevent drill cuttings and
other foreign matter from entering the chuck.
♦ Turn off the water pressure before the air pressure.
Run the rock drill for a few seconds to clean out
water and moisture after the water has been shut
off.

Regular maintenance is a basic requirement for the
continued safe and efficient use of the machine.
Follow the maintenance instructions carefully.
♦ Before starting maintenance on the machine, clean
it in order to avoid exposure to hazard substances.
See "Dust and fume hazards"
♦ Use only authorised parts. Any damage or
malfunction caused by the use of unauthorised
parts is not covered by warranty or product liability.
♦ When cleaning mechanical parts with solvent,
comply with appropriate health and safety
regulations and ensure there is satisfactory
ventilation.

Differences between original
parts and pattern parts
When buying a part, the first thing to do is to verify
that the part is an Atlas Copco part. Most parts can
be identified.
Rock drill parts are normally marked with a part
number and the Atlas Copco identity mark which is
a circle with a rock drill. In a few cases the part is
marked either with the circle only or the part number
only.
