# 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.
