Adjusting the Speed
The speed of the switched-on power tool can be variably ad-
justed, depending on how far the On/Off switch 11 is
pressed.
Light pressure on the On/Off switch 11 results in a low rota-
tional speed. Further pressure on the switch results in an in-
crease in speed.
Setting the torque
With the torque preselection ring 3, the required torque can
be preselected in 20 steps. The inserted tool is stopped as
soon as the set torque is reached.
Gear selection, mechanical
 The gear selector 5 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.
1st gear:
Low speed range; for working with large drilling diameters.
2nd gear:
High speed range; for drilling with 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 temper-
ature is not kept within the permitted range, the power tool
switches off and the LED on the power tool flashes. Allow the
power tool to cool down before you carry on working.
Protection Against Deep Discharging
The lithium-ion battery is protected against deep discharging
by the "Electronic Cell Protection (ECP)". When the battery is
empty, the machine is switched off by means of a protective
circuit: The inserted tool no longer rotates.
Rapid Shut-off
The rapid shut-off feature enables better control of the power
tool. The power tool shuts off in case of sudden and unexpect-
ed rotation of the power tool around the drilling axis.
The rapid shut-off feature is indicated by a flashing LED on the
power tool.
To restart the machine, release the On/Off switch and then
actuate again.
 Rapid shut-off can trigger only when the power tool is
running at maximum operating speed and can rotate
freely around the drill bit axis. Choose a suitable work
position for this. Otherwise, rapid shut-off will not be en-
sured.
Working Advice
 Always push the gear selector and turn the operating
mode selector switch through to the stop. Otherwise,
the machine can become damaged.
 Apply the power tool to the screw only when it is
switched off. Rotating tool inserts can slip off.
An auxiliary tool can be used to remove the screwdriver bit or
universal bit holder.
Bosch Power Tools
 Working in especially dusty environments can lead to
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
 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.
Replacing the Carbon Brushes (see figure C)
Check the length of the carbon brushes approx. every
2–3 months and replace the carbon brushes if required.
Never replace only a single carbon brush!
Note: Use only carbon brushes supplied by Bosch and intend-
ed 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 again.
When the battery is no longer operative, please refer to an au-
thorised after-sales service agent for Bosch power tools.
