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.
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 equip-
ment.
Maintenance
For maximum performance
It is important to lubricate regularly to get maximum performance and trouble-
free operation. The motor should be lubricated with oil; i.e. drops of oil can be
dropped either into the compressed air or directly into the air inlet.
The trigger, planetary gears, needle bearings and ball bearings should be lubri-
cated with grease during the regular overhaul of the machine.
The angle gear and clutch must be lubricated using grease that contains molyb-
denum disulphide: Molykote BR2 Plus, for example, or an equivalent brand.
Use lubricants of good quality. The oils and greases mentioned in the table are
examples of lubricants which are recommended.
