Installation
Installation of vibrating tools
It is recommended that a minimum length of 300
mm of flexible hose for compressed air is inserted
between a vibrating tool and the quick-action cou-
pling.
Air quality
• For optimum performance and maximum ma-
chine life we recommend the use of com-
pressed 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 microns and also removes more than
90 % of liquid water. The filter must be in-
stalled as close as possible to the machine/
equipment and prior to any other air prepara-
tion 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 quan-
tity of oil.
We strongly recommend that you install an At-
las Copco oil 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)
D = Number of drops per min (1 drop = 15
3
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 cata-
logue.
Lubrication-free models:
• In the case of lubrication-free tools it is up to
the customer to decide on the peripheral equip-
ment to be used. However, it is no disadvan-
tage if the compressed air contains a small
quantity of oil e.g. supplied from a fog lubrica-
tor (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 pres-
sure 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 air-
line 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 re-
lation to the screw joint. Check the tightening
torque given to the joint in question.
The tightening torque is adjusted by altering the
tension of the clutch spring. Turn the protection
ring until the hole in the clutch housing is free.
Then turn the out going spindle until you can see
the keyhole in the adjustment washer. Turn the ad-
justment key clockwise to decrease and anticlock-
wise to increase the torque. After the adjustment,
turn the protective ring back again.
Verification of tightening torque
Atlas Copco Torque Analyser, ACTA 3000, plus
an appropriately-sized in-line transducer, IRTT to-
gether with the available test joints are recom-
mended equipment.
