Dust/Chip Extraction
Dusts from materials such as lead-containing
coatings, some wood types, minerals and
metal can be harmful to one's health. Touch-
ing or breathing-in the dusts can cause aller-
gic reactions and/or lead to respiratory infec-
tions of the user or bystanders.
Certain dusts, such as oak or beech dust, are
considered as carcinogenic, especially in
connection with wood-treatment additives
(chromate, wood preservative). Materials
containing asbestos may only be worked by
specialists.
– Provide for good ventilation of the work-
ing place.
– It is recommended to wear a P2 filter-
class respirator.
Observe the relevant regulations in your
country for the materials to be worked.
Operation
Starting Operation
Inserting the Battery
Use only original Bosch lithium ion batter-
ies with the voltage listed on the nameplate
of your power tool. Using other batteries can
lead to injuries and pose a fire hazard.
Note: Use of batteries not suitable for the ma-
chine can lead to malfunctions of or cause dam-
age to the power tool.
Set the rotational direction switch 6 to the cen-
tre position in order to avoid unintentional start-
ing. Insert the charged battery 5 into the handle
so that it can be felt to engage and faces flush
against the handle.
Reversing the Rotational Direction

The rotational direction switch 6 is used to re-
verse the rotational direction of the machine.
However, this is not possible with the On/Off

Setting the Torque
With the torque presetting ring 2 the required
torque setting can be preselected in 20 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 7
and keep it pressed.
The light 8 is lit when the On/Off switch 7 is
slightly or completely pressed in and permits to
light the work area when the lighting conditions
are bad.
To switch off the machine, release the On/Off
switch 7.
Adjusting the Speed
The speed of the switched on power tool can be
variably adjusted, depending on how far the
