Operation

Starting Operation

Inserting the Battery
Use only original Bosch O-pack batteries
with the voltage given on the type plate of
your machine. The use of other batteries can
lead to injuries and danger of fire.
Set the rotational direction switch 10 to the cen-
tre position in order to avoid unintentional start-
ing. Insert the charged battery 8 into the handle
so that it can be felt to engage and faces flush
against the handle.
Reversing the Rotational Direction
(see figure E)
The rotational direction switch 10 is used to re-
verse the rotational 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 4 lights up
when the On/Off switch 11 is actuated
and the motor is running.
Left Rotation: For loosening or unscrewing
screws, push the rotational direction switch 10
right to the stop.
The indicator for left rotation 5 lights up
when the On/Off switch 11 is actuated
and the motor is running.
Bosch Power Tools
Setting the Torque
With the torque presetting ring 2 the required
torque setting can be preselected in 25 steps.
With the correct setting, the insert tool is
stopped as soon as the screw is screwed flush
into the material or when the adjusted torque is
reached. The safety clutch is deactivated in the
" " position, e. g. for drilling.
Select a higher setting or switch to the
" " symbol when unscrewing screws.
Gear Selection, Mechanical
Actuate the gear selector 3 only when the
machine is at a standstill.
Two speed ranges can be preselected with the
gear selector 3.
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 power light 9 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.
