Removing
– Pull the sleeve of quick-change chuck 24 to the front and
hold.
– Remove tool bit 1 from tool holder 2 and release the quick-
change chuck.
Operation
 Before any work on the power tool, remove the battery.
Starting Operation
When starting the power tool, you should first select the di-
rection of rotation with the rotational direction switch 11
since the power tool starts only when the rotational direction
switch 11 is not in the middle position (switch-on lock).
Reversing the rotational direction (see figure I)
– Right rotation: For driving in screws, push the rotational
direction switch 11 left to the stop.
– Left Rotation: For loosening or unscrewing screws, push
the rotational direction switch 11 right to the stop.
Switching On the Worklight
The work area illumination 13 makes possible the lighting of
the screwing position for unfavorable light conditions. The
work area illumination 13 is switched on by lightly pressing
the on/off switch 10. When the on/off switch is firmly
pressed, the power tool is switched on and the work area illu-
mination continues to light.
 Do not look directly into the work area illumination –
your sight can be temporarily degraded!
Switching On and Off
The screwdriver have a shut-off clutch that
depends on the torque and can be set in the
given range. It responds when the torque that
is set is reached.
– To start the machine press the on/off switch 10 to the
stop.
– The machine switches off automatically as soon as the
preset torque is reached.
 When the on/off switch 10 is released prematurely, the
preset torque is not reached.
To save energy, only switch the power tool on when using it.
Working Advice
 Apply the power tool to the screw/nut only when it is
switched off. Rotating tool inserts can slip off.
Setting the Torque (see figures J – K)
The tightening torque is dependent on the spring pretension
of the shut-off clutch. The shut-off clutch responds in right as
well as left rotation when the torque setting is reached.
For setting the individual tightening torques, use only the ad-
justment tool 25 provided.
– Push the torque selector switch 6 on the power tool com-
pletely back.

Applies for the ANGLE EXACT ION
following types:
8-1100 | 3-500 | 15-500 | 23-380 |
30-290
– Insert a hex key 26 into tool bit 1 and turn it slowly.
– When a small indentation (adjusting dial 27) is visible in
the clutch, insert the adjustment tool 25 into the indenta-
tion and turn it.
Applies for the ANGLE EXACT ION
following types: 30-300 | 40-220 | 50-210 | 60-120
– Slowly turn the tool holder 2 using an open-end spanner.
– When a small indentation (adjusting dial 27) is visible in
the clutch, insert the adjustment tool 25 into the indenta-
tion and turn it.
Turning in the clockwise direction results in a higher torque, in
the counterclockwise direction, a lower torque.
– Remove the adjustment tool 25. Shut the torque selector
switch 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 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 (see figure L)
Always use the power tool with a marking ring to insure that
the housing body is sealed from dust and dirt.
Applies for the ANGLE EXACT ION
following types: 30-300 | 40-220 | 50-210 | 60-120
For these industrial cordless angle wrenches, the angled
screw head must be removed first, see "Adjusting and Remov-
ing the Angled Drive Head", page 19.
The torque can be marked now as described below.
Applies for the ANGLE EXACT ION
following types: 8-1100 | 3-500 | 15-500
To identify individually adjusted tightening torques, the mark-
ing ring 17 an be replaced with a marking ring of another
color.
– Press off the marking ring 17 with a thin screwdriver blade,
a knife, or similar.
Screwing Fastener Indicator (green/red LED)
When the preset torque is reached, the shut off coupling re-
sponds. The LED indicator 7 lights green.
If the preset torque is not reached, the LED indicator 7 lights
red and an acoustical signal sounds. The screwing fastener
must be performed again.
Repeat Protection
When the shut-off coupling responds for a screwing fastener,
the motor shuts off. Switching on again is possible only after
a 0.7 second delay. In this manner, an unintentional re-tight-
ening of an already seated screw is avoided.
