Drilling

Set the preselection ring 3 to the "Drilling with-
out impact" symbol.
The safety clutch is deactivated in the "Drilling"
position.

Impact drilling

Set the preselection ring 3 to the "Im-
pact drilling" symbol.
In the "Impact drilling" position, the safety
clutch is deactivated and the maximum power is
always effective.

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 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.
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 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
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 indica-
tor 9 and the Power Light 8 flash rapidly when
the battery temperature is not within the opert-
ing temperature range of –30 to +65°C.
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
65 °C is exceeded, the electronic control
switches off the power tool until the tempera-
ture is in the optimum temperature range again.
The 3 LEDs of the battery charge-control indica-
tor 9 and the "Power light" 8 flash rapidly when
the battery temperature is not within the oper-
ating temperature range of –30 to +65°C and/or
when the overload protection has actuated.
