Safety and operating instructions
To avoid injury, before using or servicing tool, read
and understand separately provided safety
instructions.
Installation
Unpacking the drill
Plastic guards
Before the drill is used for the first time remove all
the plastic guards from the hose nipples.
Lubricate
After unpacking and installing the tool, pour a liberal
amount of lubrication oil in the air connection.

Lubricator (optional)
Max. 3 m (10 ft) compressed air hose between

the lubricator and the machine.
Check that you are using the correct
♦
recommended operating pressure, 6 bar (e) (87
psi).
The maximum permissible air pressure, 7 bar (e)
♦
(102 psi), must not be exceeded.
Blow any impurities out of the compressed air hose
♦
before connecting it to the machine.
Select the correct dimension and length for the
♦
compressed air hose. For hose lengths up to 30
m (100 ft), a hose with a minimum internal
diameter of 19 mm (3/4 in.) must be used. If the
hose length is between 30 and 100 m (100 and
330 ft), a hose with a minimum internal diameter
of 25 mm (1 in.) must be used.

Methods to prevent freezing
Ice formation in the silencer can occur when the
ambient air temperature is 0–10°C (32-50 °F) and
the relative humidity is high.
The machine is designed to avoid the formation of
ice in the silencer. Despite this, under extreme
conditions ice can form in the silencer.
Take the following actions to further counteract the
risk of ice formation:
Use Atlas Copco Rock Drill AIR-OIL as a lubricant.
♦
♦
Use a water separator.
If the machine freeze, never heat it to melt the ice.
Always let the ice thaw at room temperature.
Never pour methylated spirits or similar substances
into the rock drill, as they will interfere with the
lubrication and lead to increased wear.
Connecting a water separator
The length of the air hose between the compressor
and the water separator must be such that the water
vapor is cooled and condenses in the hose before
reaching the water separator.
If the ambient temperature is below 0 °C (32 °F) the
hose must be short enough to prevent the water from
freezing before reaching the water separator.
Lubrication
The lubricant is important for the machine's function
and has a great impact on the service life.
Indications of proper lubrication are the presence of
oil mist in the exhaust air and of slight traces of oil
on the drill or adapter shank. Too much lubrication
can cause starting problems, low power or uneven
performance.
In order to supply the correct volume of oil, the built
in lubricator must be checked and filled regularly. In
addition, use of an air line lubricator is recommended
to assure a constant and adequate supply of
lubricant.
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.
