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 specification 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.
