Testing of tightening torque

Torque and angle testing instrument

Testjoint and Transducer

Select testjoint and transducers according to minimum and maximum torque of
your tool

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 specifica-
tion 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

Recommended equipment for verification if tightening torque are an Atlas
Copco Torque Analyser plus an appropriately-sized transducer together with
the available test joints.

Torque range of the clutch springs

Each clutch spring gives a certain torque range. Do not adjust the torque
over the maximum recommendation as that might result in improper func-
tion and faster wear of the clutch.
