Switching on/off
To start the power tool, press and hold the on/off switch
(11).
The LED (9) lights up when the on/off switch (11) is lightly
or fully pressed, meaning that the work area is illuminated in
poor lighting conditions.
To switch off the power tool, release the on/off switch (11).
Adjusting the Speed
You can adjust the speed of the power tool when it is on by
pressing in the on/off switch (11) to varying extents.
A light pressure on the on/off switch (11) results in a low ro-
tational speed. Increased pressure on the switch causes an
increase in speed.
Pre-selecting the torque
The torque presetting ring (3) can be used to pre-select the
required torque in 20 stages. Once the set torque has been
reached, the application tool will be stopped.
Mechanical gear selection
You can press the gear selector switch (5) with the
u
power tool off or on. You should not do this at full load
or maximum torque, however.
First gear:
Low speed range; for working with a large drilling diameter
or for screwdriving.
Second gear:
High speed range; for working with a small drilling diameter.
Temperature-dependent overload protection
In normal conditions of use, the power tool cannot be over-
loaded. If the power tool is overloaded or the battery tem-
perature is not kept within the permitted range, the power
tool switches off and the LED on the power tool flashes. Al-
low the power tool to cool down before you carry on work-
ing.
Practical advice
Always slide the gear selector switch or turn the mode
u
selector switch as far as it will go. Otherwise, the power
tool may become damaged.
Only apply the power tool to the screw when the tool
u
is switched off. Rotating application tools can slip off.
An auxiliary tool can be used to remove the screwdriver bit
or universal bit holder.
Working in especially dusty environments can lead to
u
failure of the power tool. If the power tool suddenly
fails, remove the carbon brushes and check them (see
section "Replacing the carbon brushes").
Maintenance and Service
Maintenance and Cleaning
Remove the battery from the power tool before carry-
u
ing out work on the power tool (e.g. maintenance,
changing tool, etc.). The battery should also be re-

moved for transport and storage. There is risk of injury
from unintentionally pressing the on/off switch.
To ensure safe and efficient operation, always keep
u
the power tool and the ventilation slots clean.
Replacing the carbon brushes (see figure C)
Check the length of the carbon brushes around every 2–3
months and replace both carbon brushes if required.
Never replace only a single carbon brush.
Note: Only use carbon brushes supplied by Bosch and inten-
ded specifically for your product.
– Unscrew the caps (6) using a suitable screwdriver.
– Replace the spring-loaded carbon brushes (14) and
screw the caps back on.

Transport
The recommended lithium-ion batteries are subject to legis-
lation on the transport of dangerous goods. The user can
transport the batteries by road without further require-
ments.
When shipping by third parties (e.g.: by air transport or for-
warding agency), special requirements on packaging and la-
belling must be observed. For preparation of the item being
shipped, consulting an expert for hazardous material is re-
quired.
Dispatch battery packs only when the housing is undam-
aged. Tape or mask off open contacts and pack up the bat-
tery in such a manner that it cannot move around in the
packaging. Please also observe the possibility of more de-
tailed national regulations.
