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.
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 illumi-
nated when lighting conditions are insufficient.
To switch off the machine, release the On/Off switch 7.
Adjusting the Speed
The speed of the switched on power tool can be variably ad-
justed, depending on how far the On/Off switch 7 is pressed.
Light pressure on the On/Off switch 7 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 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 screwdriv-
er.
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
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.
LED
Continuous lighting 3 x green
Continuous lighting 2 x green

Flashing light 1 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 battery
temperature range of 0–70 °C is exceeded, the speed is re-
duced. The power tool will not run at full speed until reaching
the allowable battery temperature.
Working Advice
 Apply the power tool to the screw only when it is
switched off. Rotating tool inserts can slip off.
Bosch Power Tools
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
thread to approx.
