Changing the Tool (see figure C)
Before any work on the machine (e. g.,
maintenance, tool change, etc.) as well as
during transport and storage, set the rota-
tional direction switch to the centre posi-
tion. Unintentional actuation of the On/Off
switch can lead to injuries.
The drill spindle is locked when the On/Off
switch 11 is not pressed. This makes quick, con-
venient and easy changing of the tool in the drill
chuck possible.
Open the keyless chuck 2 by turning in rotation
direction
, until the tool can be inserted. Insert
the tool.
Firmly tighten the collar of the keyless chuck 2
by hand in rotation direction
cally locks the drill chuck.
The locking is released again to remove the tool
when the collar is turned in the opposite direc-
tion.
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.
Set the rotational direction switch 10 to the cen-
tre position in order to avoid unintentional start-
ing. Insert the charged battery 7 into the handle
so that it can be felt to engage and faces flush
against the handle.
Reversing the Rotational Direction
. This automati-
(see figures D–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.
Left Rotation: For loosening or unscrewing
screws, push the rotational direction switch 10
right to the stop.
Setting the Torque / Setting the Operating
Mode
The required torque can be preselected in 10
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".
The indicator for right rotation 5 lights up
when the On/Off switch 11 is actuated
and the motor is running.
The indicator for left rotation 6 lights up
when the On/Off switch 11 is actuated
and the motor is running.
