Gear I:
Low speed range; for screwdriving or working
with large drilling 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 11
and keep it pressed.
The light 9 is lit when the On/Off switch 11 is
slightly or completely pressed in and permits to
light the work area when the lighting conditions
are bad.
To switch off the machine, release the On/Off
switch 11.
Adjusting the Speed
The speed of the switched on power tool can be
variably adjusted, depending on how far the
On/Off switch 11 is pressed.
Light pressure on the On/Off switch 11 results in
a low rotational speed. Further pressure on the
switch results in an increase in speed.
Fully automatic spindle locking (Auto-lock)
When the On/Off switch 11 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 11 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 re-
lease the On/Off switch 11. By doing so, the head
of the screw does not penetrate into the materi-
al.
Bosch Power Tools
Temperature Dependent Overload Protection
When using as intended for, the power tool can-
not be subject to overload. When the load is too
high or the allowable battery temperature of
70 °C is exceeded, the electronic control switch-
es off the power tool until the temperature is in
the optimum 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
11 again.
Note: Pay attention that no metal particles enter
the power tool.
Tips
After longer periods of working at low speed, al-
low the machine to cool down by running it for
approx. 3 minutes at maximum speed with no
load.
For drilling in metal, use only perfectly sharp-
ened HSS drill bits (HSS=high-speed steel). The
appropriate quality is guaranteed 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.
2
/ 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 0 °C and 45 °C. As an example,
do not leave the battery in the car in summer.
Occasionally clean the venting slots of the bat-
tery using a soft, clean and dry brush.
A significantly reduced working period after
charging indicates that the battery is used and
must be replaced.
Observe the notes for disposal.
