Operation
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 8 to the centre position in
order to avoid unintentional starting. Insert the charged bat-
tery 7 into the handle so that it can be felt to engage and faces
flush against the handle.
Reversing the rotational direction (see figure F)
The rotational direction switch 8 is used to reverse the rota-
tional 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 15 steps. With the correct setting, the
insert tool is stopped as soon as the screw is screwed flush in-
to the material or when the adjusted torque is reached. The
safety clutch is deactivated in the "
drilling.
Select a higher setting or switch to the "
screwing 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 drill-
ing 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 drill chuck with drill bit.
Switching On and Off
To start the machine, press the On/Off switch 9 and keep it
pressed.
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 ad-
justed, depending on how far the On/Off switch 9 is pressed.
Light pressure on the On/Off switch 9 results in a low rotation-
al speed. Further pressure on the switch results in an increase
in speed.

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 release the On/Off switch 9.
By doing so, the head of the screw does not penetrate into the
material.
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 battery
temperature range is exceeded, the speed is reduced. The
power tool will not run at full speed until reaching the allow-
able battery temperature.
To save energy, only switch the power tool on when using it.
Working Advice
 Apply the power tool to the screw only when it is
switched off. Rotating tool inserts can slip off.
After longer periods of working at low speed, allow the ma-
chine to cool down by running it for approx. 3 minutes at max-
imum speed with no load.
For drilling in metal, use only perfectly sharpened HSS drill
bits (HSS=high-speed steel). The appropriate quality is guar-
anteed by the Bosch accessories program.
Before screwing larger, longer screws into hard materials, it is
" position, e. g. for
advisable to predrill a pilot hole with the core diameter of the
thread to approx.
