Set the rotational direction switch 7 to the centre position to
protect the power tool against accidental starting.
Insert the charged battery 6 from the front into the base of the
power tool. Push the battery completely into the base until
the red stripe can no longer be seen and the battery is secure-
ly locked.
Reversing the rotational direction (see figure C)
The rotational direction switch 7 is used to reverse the rota-
tional direction of the machine. However, this is not possible
with the On/Off switch 8 actuated.
Right Rotation: For drilling and driving in screws, push the
rotational direction switch 7 left to the stop.
Left Rotation: For loosening and unscrewing screws and
nuts, press the rotational direction switch 7 through to the
right stop.
Setting the torque
The required torque can be preselected in 20 steps with the
torque preselection ring 2. With the correct setting, the insert
tool is stopped as soon as the screw is screwed flush into the
material or when the set torque is reached.
Select a higher setting when driving out screws, or set to the
symbol "Drilling".
Gear selection, mechanical
 The gear selector 3 can be actuated at standstill or
when the machine is running. However, this should not
be done while operating at full load or maximum speed.
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 8 and keep it
pressed.
To switch off the machine, release the On/Off switch 8.
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 ad-
justed, depending on how far the On/Off switch 8 is pressed.
Light pressure on the On/Off switch 8 results in a low rotation-
al speed. Further pressure on the switch results in an increase
in speed.
Fully automatic spindle locking (Auto-lock)
When the On/Off switch 8 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 8 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 8.
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 of 65 °C is exceeded, the electronic control
switches off the power tool until the temperature is in the op-
timum temperature range again.

Working Advice

 Apply the power tool to the screw only when it is
switched off. Rotating tool inserts can slip off.
When the power tool is electrostatically charged, the built-in
electronic control switches it off. To restart the power tool,
press the On/Off switch 8 again.
Tips
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
advisable to predrill a pilot hole with the core diameter of the
2
thread to approx. / of the screw length.

Recommendations for Optimal Handling of the Battery
Protect the battery against moisture and water.
Store the battery only within a temperature range between
–20 °C and 50 °C. As an example, do not leave the battery in
the car in summer.
Occasionally clean the venting slots of the battery using a soft,
clean and dry brush.
A significantly reduced working period after charging indi-
cates that the battery is used and must be replaced.
Observe the notes for disposal.

Maintenance and Service

Maintenance and Cleaning

 Before any work on the machine itself (e. g. mainte-
nance, tool change, etc.) as well as during transport
and storage, remove the battery from the power tool.
There is danger of injury when unintentionally actuating
the On/Off switch.
 For safe and proper working, always keep the machine
and ventilation slots clean.
