If the securing screw 14 is seated tightly, apply
a screwdriver to the screw head and loosen the
securing screw by giving a blow onto the handle
of the screwdriver.
Removing the Drill Chuck (see figure E)
Clamp the short end of an Allen key 15 into the
keyless chuck 2.
Place the machine on a stable surface (e. g. a
workbench). Hold the machine firmly and loos-
en the keyless chuck 2 by turning the Allen key
15 in rotation direction . Loosen a tight-seated
keyless chuck by giving the long end of the Allen
key 15 a light blow. Remove the Allen key from
the keyless chuck and completely unscrew the
keyless chuck.
Mounting the Drill Chuck (see figure F)
The keyless chuck is mounted in reverse order.
The drill chuck must be tightened with a
tightening torque of approx. 7–9 Nm.
Screw the securing screw 14 in anti-clockwise
direction into the opened keyless chuck, tight-
ening torque approx. 1.5–2.5 Nm. Always use a
new securing screw, as the threads are covered
with a thread-locking compound that loses its
effect after multiple usage.

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
(see figure C)
The rotational direction switch 10 is used to
reverse 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 5 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 6 lights up
when the On/Off switch 11 is actuated
and the motor is running.
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.
