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 con-
nection with wood-treatment additives (chro-
mate, wood preservative). Materials contain-
ing asbestos may only be worked by
specialists.
– Use dust extraction whenever possible.
– Provide for good ventilation of the working
place.
– It is recommended to wear a P2 filter-class
respirator.
Observe the relevant regulations in your coun-
try for the materials to be worked.
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 7 to the centre
position in order to avoid unintentional starting.
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
(see figure E)
The rotational direction switch 7 is used to re-
verse the rotational direction of the machine.
However, this is not possible with the On/Off
switch 8 actuated.

Right Rotation: For drilling and driving in screws,
push the rotational direction switch 7 left to the
stop.
Left Rotation: For loosening or unscrewing
screws, push the rotational direction switch 7
right to the stop.
Setting the Torque
The required torque can be preselected in 15
steps with the torque preselection ring 2. 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".
Gear Selection, Mechanical
The gear selector 3 can be actuated at stand-
still or when the machine is running. Howev-
er, this should not be done while operating
at full load or maximum speed.
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 8
and keep it depressed.
To switch off the machine, release the On/Off
switch 8.
Adjusting the Speed
The speed of the switched on power tool can be
variably adjusted, depending on how far the
On/Off switch 8 is pressed.
Light pressure on the On/Off switch 8 results in
a low rotational speed. Further pressure on the
switch results in an increase in speed.
