Practical advice

The torque depends on the spring preload of the shut-off clutch. The shut-off clutch is triggered upon reaching the set torque, both in clockwise and anticlockwise rotation.

Only use the supplied adjustment tool (20) to set the individual torque.

  • Push the cover for the clutch back.
  • Insert the application tool (20) into the small protrusion (setting disc (21)) of the clutch and turn the adjustment tool (20).

Turning clockwise will result in a higher torque; turning anticlockwise will result in a lower torque.

  • Remove the adjustment tool (20). Push the cover for the clutch  until the opening is closed to protect the clutch from contamination.

Note: The required setting is dependent on the type of threaded connector and can be best determined by practical trials. Check a trial screw application with a torque spanner.

  • If you set the torque to a value outside the specified power range, the shut-off clutch will not be triggered.
  • Check the torque regularly.

The shut-off clutch is triggered upon reaching the preset torque. The LED indicator (5) lights up green.

If the preset torque has not been reached, the LED indicator (5) lights up red and the tool emits a sound. The screw must be driven in again.

If the shut-off clutch is triggered while driving a screw, the motor will switch off. You will need to wait 0.7 seconds before you can switch the tool on again. This prevents you from accidentally retightening screws that are already firmly in place.
