Set the rotational direction switch 8 to the cen-
tre position in order to avoid unintentional start-
ing. Insert the charged battery 7 into the handle
so that it can be felt to engage and faces flush
against the handle.
Reversing the Rotational Direction
(see figure C)
The rotational direction switch 8 is used to re-
verse the rotational direction of the machine.
However, this is not possible with the On/Off
switch 9 actuated.
Right Rotation: For drilling and driving in
screws, push the rotational direction switch 8
left to the stop.
Left Rotation: For loosening and unscrewing
screws and nuts, press the rotational direction
switch 8 through to the right stop.
Setting the Torque
With the torque presetting ring 4 the required
torque setting can be preselected in 20 steps.
With the correct setting, the insert tool is
stopped as soon as the screw is screwed flush
into the material or when the adjusted torque is
reached. The safety clutch is deactivated in the
" " position, e. g. for drilling.
Select a higher setting or switch to the
" " symbol when unscrewing screws.
Gear Selection, Mechanical
Actuate the gear selector 5 only when the
machine is at a standstill.
Two speed ranges can be preselected with the
gear selector 5.
Gear I:
Low speed range; for screwdriving or working
with large drilling diameter.
Gear II:
High speed range; for working with small drilling
diameter.
If the gear selector 5 cannot be pushed through
to the stop, lightly turn the tool holder 2 with
the insert tool.

Switching On and Off
To start the machine, press the On/Off switch 9
and keep it pressed.
The power light 10 lights up when the On/Off
switch 9 is slightly or completely pressed, and
allows the work area to be illuminated when
lighting conditions are insufficient.
To switch off the machine, release the On/Off
switch 9.
Adjusting the Speed
The speed of the switched on power tool can be
variably adjusted, depending on how far the
On/Off switch 9 is pressed.
Light pressure on the On/Off switch 9 results in
a low rotational speed. Further pressure on the
switch results in an increase in speed.
Fully automatic spindle locking (Auto-lock)
When the On/Off switch 9 is not pressed, the
drill spindle and thus the tool holder are locked.
This enables screws to be screwed in, even
when the battery is empty and allows for the
machine to be used as a screwdriver.
Run-on Brake
When the On/Off switch 9 is released, the chuck
brakes to a stop, thus preventing the run-on of
the tool.
When driving in screws, wait until the screw is
screwed in flush with the material and then re-
lease the On/Off switch 9. By doing so, the head
of the screw does not penetrate into the materi-
al.
Temperature Dependent Overload Protection
When using as intended for, the power tool can-
not be subject to overload. When the load is too
high or the allowable battery temperature range
of 0–70 °C is exceeded, the speed is reduced.
The power tool will not run at full speed until
reaching the allowable battery temperature.
