Gear Selection, Mechanical
Actuate the gear selection lever 5 only when
the machine is at a complete standstill.
Two speed ranges can be preselected with the
gear selection lever 5.
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 5 cannot be pushed through
to the stop, lightly turn the drill chuck.
Switching On and Off
To start the power tool, press the On/Off switch
10 and keep it pressed.
To switch off the power tool, release the On/Off
switch 10.
Adjusting the Speed
The speed of the switched on power tool can be
variably adjusted, depending on how far the
On/Off switch 10 is pressed.
Light pressure on the On/Off switch 10 results in
a low rotational speed. Further pressure on the
switch results in an increase in speed.
Run-on Brake
When the On/Off switch 10 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 10. By doing so, the head
of the screw does not penetrate into the materi-
al.

Working Instructions
Apply the power tool to the screw only when
it is switched off. Rotating tool inserts can
slip off.
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.

Maintenance and Service
Maintenance and Cleaning
Before any work on the power tool (e. g.,
maintenance, tool change, etc.) as well as
during transport and storage, set the rota-
tional direction switch to the center posi-
tion. Unintentional actuation of the On/Off
switch can lead to injuries.
For safe and proper working, always keep
the power tool and the ventilation slots
clean.
If the power tool should fail despite the care tak-
en in manufacturing and testing procedures, re-
pair should be carried out by an after-sales ser-
vice center for Bosch power tools.
In all correspondence and spare parts orders,
please always include the 10-digit article number
given on the type plate of the power tool.
