Starting Operation
Inserting the Battery
Note: Use of batteries not suitable for the machine can lead
to malfunctions of or cause damage to the power tool.
Set the rotational direction switch 6 to the centre position in
order to avoid unintentional starting. Insert the charged bat-
tery 5 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 6 is used to reverse the rota-
tional direction of the machine. However, this is not possible
with the On/Off switch 7 actuated.
Right Rotation: For drilling and driving in screws, push the
rotational direction switch 6 left to the stop.
Left Rotation: For loosening and unscrewing screws and
nuts, press the rotational direction switch 6 through to the right
stop.
Setting the Torque
With the torque presetting ring 2 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 "
ing.
Select a higher setting or switch to the "
unscrewing screws.
Gear Selection, mechanical
Actuate the gear selector 3 only when the
machine is at a standstill.
Two speed ranges can be preselected with the gear selector
3.
Gear I:
Low speed range; for screwdriving or working with large drill-
ing diameter.
Gear II:
High speed range; for working with small drilling diameter.
If the gear selector 3 cannot be pushed through to the stop,
lightly turn the drill chuck with drill bit.
Switching On and Off
To start the machine, press the On/Off switch 7 and keep it
pressed.
The power light 9 lights up when the On/Off switch 7 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 7.
To save energy, only switch the power tool on when using it.
Adjusting the Speed
The speed of the switched-on power tool can be variably
adjusted, depending on how far the On/Off switch 7 is
pressed.
Light pressure on the On/Off switch 7 results in a low rota-
tional speed. Further pressure on the switch results in an
increase in speed.
Fully Automatic Spindle Locking
(Auto-lock)
When the On/Off switch 7 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 screw-
driver.
Run-on Brake
When the On/Off switch 7 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 release the On/Off switch 7. By
doing so, the head of the screw does not penetrate into the
material.

Battery Charge-control Indication
" symbol when
The battery charge-control indicator 8 consists of three green
LEDs, and indicates the charge condition of the battery for a
few seconds when the On/Off switch 7 is pressed halfway or
fully.

Continuous lighting 3 x green
Continuous lighting 2 x green

Temperature Dependent Overload
Protection
When using as intended for, the power tool cannot be subject
to overload. When the load is too high or the allowable bat-
tery temperature range is exceeded, the speed is reduced.
The power tool will not run at full speed until reaching the
allowable battery temperature.
