postures.
►Changing posture during extended tasks may help
avoid discomfort and fatigue.
►In case of persistent or recurring symptoms,
consult a qualified health professional.
WARNING Vibration hazards
Normal and proper use of the machine exposes the
operator to vibration. Regular and frequent exposure
to vibration may cause, contribute to, or aggravate
injury or disorders to the operator’s fingers, hands,
wrists, arms, shoulders and/or nerves and blood
supply or other body parts, including debilitating
and/or permanent injuries or disorders that may
develop gradually over periods of weeks, months, or
years. Such injuries or disorders may include damage
to the blood circulatory system, damage to the
nervous system, damage to joints, and possibly
damage to other body structures.
If numbness, persistent recurring discomfort, burning
sensation, stiffness, throbbing, tingling, pain,
clumsiness, weakened grip, whitening of the skin, or
other symptoms occur at any time, when operating
the machine or when not operating the machine, stop
operating the machine, tell your employer and seek
medical attention. Continued use of the machine after
the occurrence of any such symptom may increase
the risk of symptoms becoming more severe and/or
permanent.
Operate and maintain the machine as recommended
in these instructions, to prevent an unnecessary
increase in vibration.
The following may help to reduce exposure to
vibration for the operator:
►Let the tool do the job. Use a minimum hand grip
consistent with proper control and safe operation.
►If the machine has vibration absorbing handles,
keep them in a central position, avoid pressing the
handles into the end stops.
►When the percussion mechanism is activated, the
only body contact with the machine you should
have are your hands on the handle or handles.
Avoid any other contact, for example supporting
any part of the body against the machine or
leaning onto the machine trying to increase the
feed force. It is also important not to keep the start
and stop device engaged while extracting the tool
from the broken work surface.
►Make sure that the inserted tool is well-maintained
(including sharpness, if a cutting tool), not worn
out, and of the proper size. Insertion tools that are
not well-maintained, or that are worn out, or that
are not of the proper size result in longer time to
complete a task (and a longer period of exposure
to vibration) and may result in or contribute to
higher levels of vibration exposure.
►Immediately stop working if the machine suddenly
starts to vibrate strongly. Before resuming the
work, find and remove the cause of the increased
vibrations.
►Never grab, hold or touch the inserted tool when
using the machine.

Safety label
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.
Hoses and connections
A. Compressed air source
B. Water separator (optional)
C. Lubricator (optional)
D. 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.

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.

Noise and vibration declaration statement
Guaranteed sound power level Lw according to ISO 3744 in accordance with directive 2000/14/EC.
Sound pressure level Lp according to ISO 11203.
Vibration value Aand uncertainty Bdetermined according to ISO 20643. See table ”Noise and vibration data”
for the values of A, B, etc.
These declared values were obtained by laboratory type testing in accordance with the stated directive or
standards and are suitable for comparison with the declared values of other tools tested in accordance with
the same directive or standards. These declared values are not suitable for use in risk assessments and values
measured in individual work places may be higher. The actual exposure values and risk of harm experienced
by an individual user are unique and depend upon the way the user works, in what material the machine is
used, as well as upon the exposure time and the physical condition of the user, and the condition of the machine.
We, Atlas Copco Construction Tools AB, cannot be held liable for the consequences of using the declared
values, instead of values reflecting the actual exposure, in an individual risk assessment in a work place situation
over which we have no control.
This tool may cause hand-arm vibration syndrome if its use is not adequately managed. An EU guide to managing
hand-arm vibration can be found at http://www.humanvibration.com/EU/VIBGUIDE.htm
