Safety and operating instructions
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 recommend the installation of an Atlas Copco refrigeration-
type air dryer.
■
Use a separate air filter of type Atlas Copco FIL. This filter removes solid particles larger than 15 mi-
crons and also removes more than 90 % of liquid water. The filter must be installed as close as possi-
ble 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 lubricator (DIM). This should be set ac-
cording to air consumption by the air line tool according to the following formula:
L = Air consumption (litre/s)
D = Number of drops per min (1 drop = 15 mm
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.
■
Note – This does not apply to turbine tools, which should be kept oil free.
Compressed air connection
■
The machine is designed for a working pressure of 6–7 bar = 600–700 kPa = 87–102 psi.
■
Blow out the hose before connecting.
Installation proposal
Choosing the correct couplings, hose and clamps can be a troublesome digging into details. To save your
time and to ensure correct capacity of the airline installation, from the tapping point to the tool, we offer
you an installation proposal.

Handling
Tightening torque
For accurate operation and safety, the tightening torque of the nut runner must be set correctly in relation
to the screw joint. Check the tightening torque given to the joint in question.
