– When a small indentation (adjusting dial 27)
is visible in the clutch, insert the adjustment
tool 25 into the indentation and turn it.
Turning in the clockwise direction results in a
higher torque, in the counterclockwise direc-
tion, a lower torque.
– Remove the adjustment tool 25. Shut the
torques setting cover 6 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 fastenings with a torque wrench.
Set the torque only in the specified perfor-
mance range, otherwise the shut-off clutch
will no longer respond.
Marking the Torque Setting
Always use the power tool with a marking ring
to insure that the housing body is sealed from
dust and dirt.
Applies for the following types: ANGLE EX-
ACT ION 30-300, 40-220, 50-210, 60-120.
For these industrial cordless angle wrenches,
the angle head must be removed first, see "Ad-
justing and Removing the Angle head" , page

When the preset torque is reached, the shut
off coupling responds. The LED indicator 7
lights green (Fig. 1).
If the preset torque is not reached, the LED
indicator 7 lights red and an acoustical signal
sounds. The tightening fastener must be per-
formed again.
When the shut-off coupling responds for a
tightened fastener, the motor shuts off. Switch-
ing on again is possible only after a 0.7 sec-
ond delay. In this manner, an unintentional
re-tightening of an already seated screw is
avoided.
