Tightening torque

For accurate operation and safety, the tightening
torque of the screwdriver must be adjuisted correctly
in relation to the screw joint. Check the torque spe-
cification for the actual joint.

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 adjustment key
clockwise to decrease and anticlockwise 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 together
with the available test joints are recommended
equipment.

Torque range of the clutch springs :

Each clutch spring gives a certain torque
range. Don’t adjust the torque over the max-
imum recommendation as that might result
in improper function and faster wear of the
clutch.

The torque range of each spring is easily identified
by it’s colour.

Maintenance

For maximum performance

At tough working conditions - soft joints and max.
setting - lubrication of the air is recommended.

With extreme dry air service life of vanes and tool

power may be reduced. A daily supply of oil (0.1 -
0.2 ml into the machine inlet or consider an automat-
ic lubricator device of the type Atlas Copco oil fog
lubricator DIM or single point lubricator DOS, which
will improve the machine performance.

Rust protection and internal cleaning

Water in the compressed air, dust and wear particles
cause rust and sticking of vanes, valves etc. An air
filter should be installed close to the machine (se
‘Air quality’). Before longer standstills, flush with
oil (some drops) into the air inlet, run the machine
for 5-10 seconds when absorbing the oil in a cloth.

Service instructions

Overhaul and preventive maintenance is recommen-
ded at regular intervals once per year or after maxim-
um 250.000 tightenings depending on which occurs
sooner. More frequent overhaul may be needed, if
used at high torque and long tightening times. If the

machine not is working properly, it should immedi-
ately be taken away for inspection.

The strainer at the air inlet and the exhaust silencer

should be cleaned frequently or replaced in order to
prevent clogging, which decreases the capacity.

At the overhauls, all parts should be cleaned accur-

ately and defective or worn parts (i.e. O-rings, vanes)
should be replaced.

Disassembling /assembling

It is important that the machines threaded connec-
tions are tightened properly; i.e. in accordance with
the specifications on the exploded views.

Cleaning

Clean all parts thoroughly in white spirit or similar
cleaning agent.

To prevent clogging and decreased power, it could

be necessary to clean the strainer (if used) and the
exhaust filter between the overhauls.
