Adjusting the torque
The tightening torque is adjusted by changing the tension of the clutch spring with the key and the adjustment disc (clutch adjusting kit).
Start at a low torque setting to prevent screw joint damage. If the torque is set too high, there will be no click-sound from the clutch, the green LED will not lit and the motor will be turned off.
Do not adjust the torque over the recommended maximum value as it will result in incorrect function and faster wear.
Put the key in the hole at the front part of the tool.
Turn the key clockwise to increase the tightening torque.
Finish the adjustment at a holding position, located each 1.5 turns of the key.
