Operation

Starting Operation

Inserting the Battery
Use only original Bosch lithium ion batteries
with the voltage listed on the nameplate of
your power tool. Using other batteries can
lead to injuries and pose a fire hazard.
Set the rotational direction switch 11 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 C)
The rotational direction switch 11 is used to re-
verse the rotational direction of the machine.
However, this is not possible with the On/Off
switch 12 actuated.
Right Rotation: For drilling and driving in screws,
push the rotational direction switch 11 left to the
stop.
The indicator for right rotation 5 lights up
when the On/Off switch 12 is actuated
and the motor is running.

screws, push the rotational direction switch 11
right to the stop.
The indicator for left rotation 6 lights up
when the On/Off switch 12 is actuated

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 ma-
terial 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 12
and keep it depressed.
The power light 9 lights up when the On/Off
switch 12 is slightly depressed, and enables illu-
mination of the screwing location in unfavourable
light conditions.
To switch off the machine, release the On/Off
switch 12.
