Remove the adjustment tool 22.
Shut the torque selector switch 10 again to protect the clutch
against contamination.
Note: The required adjustment is dependent on the type of
threaded connection and can be best determined by practical
trials. Check the trial screwings with a torque wrench.
 Set the torque only in the specified performance range,
otherwise the shut-off clutch will no longer respond.
Marking the Torque Setting
To identify individually adjusted tightening torques, the mark-
ing ring 4 an be replaced with a marking ring of another color.
Press off the marking ring 4 with a thin screwdriver blade, a
knife, or similar.
Always use the power tool with a marking ring to insure that
the housing body is sealed from dust and dirt.
LED indicator for screwdriving applications
When the preset torque is reached, the shut off coupling re-
sponds. The LED indicator 6 lights green.
If the preset torque is not reached, the LED indicator 6 lights
red and an acoustical signal sounds. The screwing fastener
must be performed again.
Repeat protection on corded straight screwdrivers with
lever start
When the shut-off coupling responds for a screwing fastener,
the motor shuts off. Switching on again is possible only after
a 0.3 second delay. In this manner, an unintentional re-tight-
ening of an already seated screw is avoided.
Repeat protection on corded straight screwdrivers with
push start
The power tools are not equipped with restarting protection
and can be switched on directly again following an automatic
shut-off.
