Removing the Tool
Pull the quick change chuck 9 to the front. Take the
tool 11 out of the tool holder 10 and release the quick
change chuck 9.

Putting into Operation

When starting the power tool, you should first select
the direction of rotation with the right/left rotation
switch 3 since the power tool starts only when the
right/left rotation switch 3 is not in the middle position
(switch-on lock).
Setting the Direction of Rotation
3
Right rotation: Press the right/left rotation switch 3 to
the left to the stop (Screwing in of
screws).
Left rotation: Press the right/left rotation switch 3 to
the right to the stop (Loosening or un-
screwing of screws).
Operate the right/left rotation switch 3
only when the power tool is at a stand-
still.
Switching on the LED work area illumination
lamp
The working light 8 makes possible the lighting of the
screwing position for unfavorable light conditions. The
working light 8 is switched on by lightly pressing the
on/off switch 6. When the on-off switch 6 is firmly
pressed, the power tool is switched on and the work-
ing area light 8 continues to light.
Do not look directly into the working
light – your sight can be temporarily de-
graded!

Switching On/Off
The tools have a torque dependent switch-off cou-
pling that is adjustable in the specified range. It re-
sponds when the torque that is set is reached.
Switching on: Press the on/off switch 6 to the stop.
The tool switches off automatically
when the adjusted torque setting is
reached.
Switching off: Release the on/off switch 6.
When the on/off switch 6 is released premau-
rely, the preset torque is not reached.

Working Instructions

Remove the battery from the power tool before
adjustments are made to the tool, accessories
are changed or the tool is stored. This safety
measure prevents the unintentional switching on of the
power tool.
Removing the Battery
The battery 4 is located in the handle of the power tool.
Press the unlocking buttons 5 on both sides and pull
the battery 4 downward out of the handle. Do not use
force.
Setting the Torque
The tightening torque is dependent on the spring pre-
tension of the switch-off coupling. The switch-off cou-
pling responds in right as well as left rotation when the
torque setting is reached.
For setting the individual tightening torques, use only
the adjustment tool 13 provided (Fig.
Push the slide 12 on the power tool completely back.
Insert the adjustment tool 13 into the tool holder 10
and turn slowly until a small indentation is visible in the
power tool opening on the coupling (Fig.
the adjustment tool 13 into this indentation and turn
the adjustment tool 13.
Turning in the clockwise direction results in a higher
torque, in the counter clockwise direction, a lower
toque.
Note: The required adjustment is dependent on the
type of threaded connection and can be best deter-
mined by practical trial. Check the trial screwings with
a torque wrench.
Set the torque only in the specified per-
formance range, otherwise the shut-off
coupling will no longer respond.
