Use Atlas Copco Rock Drill AIR-OIL which is
specially developed for pneumatic rock drills. Rock
Drill AIR-OIL is readily biodegradable according to
OECD 301 and has high film strength that can
withstand heavy loads. If Rock Drill AIR-OIL is not
available use a mineral-based air tool oil with the
properties recommended in the table below.
Viscosity grade

Daily before using and after each four hours of
service, remove the plug (A) and saturate the felt
and fill the cavity with recommended oil.
Insertion tool
CAUTION Hot insertion tool
The tip of the insertion tool can become hot and
sharp when used. Touching it can lead to burns and
cuts.
► Never touch a hot or sharp insertion tool.
► Wait until the insertion tool has cooled down before
carrying out maintenance work.
Selecting the right insertion tool
Selecting the right insertion tool is a precondition for
proper machine function. It is important to select
insertion tools of high quality to avoid unnecessary
machine damage.
The machine can be destroyed if you use an incorrect
insertion tool.
Recommended insertion tools are listed in the
machine's spare parts list.
WARNING Vibration hazard
Using inserted tools that do not fulfil the criterias
mentioned below, will result in a longer time to
complete a task, and may result in higher levels of
vibration exposure. A worn tool will also cause
increased working time.
► Make sure that the inserted tool is well-maintained,
not worn out and of the proper size.
► Always use a sharp tool in order to work efficiently.
NOTICE Never cool a hot insertion tool in water, it
can result in brittleness and early failure.
WARNING Ejected insertion tool
If the tool retainer on the machine is not in a locked
position, the inserted tool can be ejected with force,
which can cause personal injury.
► Before changing the insertion tool, stop the
machine, switch off the compressed air supply
and bleed the machine by activating the start and
stop device.
Before fitting the insertion tool
Check that the tool shank is of the correct size and
length for the chuck used. The shank must be clean
and the tool must be in good condition. Shanks which
are chipped, rounded, out of square or too hard on
the striking end will operate inefficiently and cause
premature piston failure.
Inspect the drill steel:
A dull drill steel will slow down the drilling speed and
overstrain the drill mechanism. When changing drill
steel make sure that the new one is the correct size
to follow your previous bore.
Before drilling, check that the flushing hole in the drill
steel is not blocked.
