Safety instructions
Warning
• Make sure you are familiar with the operating in-
structions before you use this machine.
• Before making any adjustments (e.g. setting the
torque, changing bits) disconnect the machine
from the compressed air line.
• The machine, together with any attachments and
accessories, must never be used for anything other
than the designed purpose.
• Use power sockets only. For safe and economic
use - replace worn sockets.
• Check that the power socket is properly fastened
- replace the square drive retainer when necessary.
• Keep your fingers and loose articles (cloths, hair)
away from the outgoing shaft.
• Do not use gloves.
• Hold the machine correctly and be aware of the
reaction force.
• Check the position of the reversing valve before
start.
• Check the correct clutch function after any adjust-
ment. Decreased air pressure may produce that
the clutch not disconnect properly.
• Check that the suspension yoke is in good condi-
tion and correctly fastened.
• Use support handle or torque arm at high torque
settings or stressed working positions.

Installation
Air quality
• For optimum performance and maximum machine
life we recommend the use of compressed air with
a maximum dew point of +10°C. We also recom-
mend the installation of an Atlas Copco refrigera-
tion-type air dryer.
• Use a separate air filter of type Atlas Copco FIL.
This filter removes solid particles larger than 15
microns and also removes more than 90 % of li-
quid water. The filter must be installed as close
as possible to the machine/equipment and prior
to any other air preparation unit such as REG or
DIM (please see Air Line Accessories in our main
catalogue). Blow out the hose before connecting.
Models which need air lubrication:
• The compressed air must contain a small quantity
of oil.
We strongly recommend that you install an Atlas
Copco oil-fog lubricator (DIM). This should be
set according to air consumption by the air line
tool according to the following formula:
L
= Air consumption (litre/s).
(May be found in our sales literature).
D
= Number of drops per min (1 drop = 15 mm3)
L* 0.2 = D
this applies to the use of long work cycle air line
tools. A single point lubricator type Atlas Copco
Dosol can also be used for tools with short running
cycles.
Information about Dosol settings may be found
under Air Line Accessories in our main catalogue.
Lubrication-free models:
• In the case of lubrication-free tools it is up to the
customer to decide on the peripheral equipment
to be used. However, it is no disadvantage if the
compressed air contains a small quantity of oil
e.g. supplied from a fog lubricator (DIM) or Dosol
system.
This does not apply to turbine tools, which should
be kept oil free.
Compressed air connection
• The machine is designed for a working pressure
(e) of 6–7 bar = 600–700 kPa = 87–102 psi.
• Blow out the hose before connecting.
