Gear Selection, Mechanical
u Actuate the gear selector 5 only when the machine is
at a standstill.
Two speed ranges can be preselected with the gear selector 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 tool holder 2 with the insert tool.
Switching On and Off
To start the machine, press the On/Off switch 9 and keep it
pressed.
The power light 10 lights up when the On/Off switch 9 is
slightly or completely pressed, and allows the work area to
be illuminated when lighting conditions are insufficient.
To switch off the machine, release the On/Off switch 9.
Adjusting the Speed
The speed of the switched on power tool can be variably
adjusted, depending on how far the On/Off switch 9 is pressed.
Light pressure on the On/Off switch 9 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 9 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 9 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 9. By doing so,
the head of the screw does not penetrate into the material.
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 reduced. The power tool will not run at full speed
until reaching the allowable battery temperature.
Working Advice
u 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, allow 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 sharpened 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. /

Maintenance and Cleaning

u Before any work on the machine itself, pull the mains
plug.
u For safe and proper working, always keep the
machine and ventilation slots clean.
u Clean the buzzer and head after end of service, thus
avoiding the concrete to dry over their surface,
damaging them.
u Store the vibrator thoroughly clean, protected and
wrapped.
u Pay attention to the buzzer connection so as to not
pour water into the hose during cleaning, as concrete
remains may enter into the hose and damage the
product (flexible breakage and bearings locking).
Accessories must be stored and handled with care.
