Safety and operating instructions
Maintenance
Regular maintenance is a prerequisite for machine
safety. Replace damaged and worn components
in good time. For a major service to the machine,
contact your nearest authorized workshop.
Check the machine and tools for wear and damage
at regular intervals. Do not use very worn or
damaged tools.
When cleaning mechanical parts with a solvent,
make sure that you comply with current health
and safety regulations and ensure that there is
sufficient ventilation.
Daily maintenance, regular checking of wearing
parts and carrying out repairs in good time
prevents breakdowns and increases the service life
of the machine.
Always oil the pusher leg well, before you put
them into storage.
Store in a clean and dry place.
Make sure that no foreign matter enters the
machine.
Protect the chuck using the plastic plug provided
with the machine. Alternatively, use a wooden
plug or a clean piece of cotton waste.
Always hose down and wipe clean the rock drill
and pusher leg after use.
In the case of long-term storage, pour a quantity
of oil directly into the rock drill's air intake and
then turn on the air briefly. This will protect the
machine from corrosion.
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 inside it. In a few cases the part is marked
either with the circle only or the part number only.
