Reversing the Rotational Direction (see figure C)
The rotational direction switch 10 is used to reverse the rota-
tional direction of the machine. However, this is not possible
with the On/Off switch 11 actuated.
Right Rotation: For drilling and driving in screws, push the
rotational direction switch 10 left to the stop.
The indicator for right rotation 5 lights up when the
On/Off switch 11 is actuated and the motor is run-
ning.
Left Rotation: For loosening or unscrewing screws, push the
rotational direction switch 10 right to the stop.
The indicator for left rotation 6 lights up when the
On/Off switch 11 is actuated and the motor is run-
ning.
Setting the Torque
The required torque can be preselected in 25 steps with the
torque preselection ring 3. With the correct setting, the insert
tool is stopped as soon as the screw is screwed flush into the
material or when the set torque is reached.
Select a higher setting when driving out screws, or set to the
symbol "Drilling".
Drilling
The safety clutch is deactivated in the "Drilling" position.
Gear Selection, Mechanical
Actuate the gear selector 4 only when the machine is at
a standstill.
Two speed ranges can be preselected with the gear selector
4.
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 4 cannot be fully engaged, lightly rotate
the drive spindle with the drill bit by twisting the drill chuck.
Switching On and Off
To start the machine, press the On/Off switch 11 and keep it
pressed.
The power light 8 lights up when the On/Off switch 11 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 11.
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.
Bosch Power Tools
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 screwdriv-
er.
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 release the On/Off switch 11.
By doing so, the head of the screw does not penetrate into the
material.
Battery Charge-control Indication
The battery charge-control indicator 9 consists of three green
LEDs, and indicates the charge condition of the battery for a
few seconds when the On/Off switch 11 is pressed halfway or
fully.
LED
Continuous lighting 3 x green
Continuous lighting 2 x green
Continuous lighting 1 x green
Slow flashing 1 x green
The 3 LEDs of the battery charge-control indicator 9 and the
Power Light 8 flash rapidly when the battery temperature is
not within the operating temperature range of –10 to +70°C.
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 of 70 °C is exceeded, the electronic control
switches off the power tool until the temperature is in the op-
timum temperature range again.
The 3 LEDs of the battery charge-control indicator 9 and the
"Power light" 8 flash rapidly when the battery temperature is
not within the operating temperature range of –10 to +70°C
and/or when the overload protection has actuated.
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.
Working Advice
Apply the power tool to the screw only when it is
switched off. Rotating tool inserts can slip off.
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
2
thread to approx. / of the screw length.
