The locking is released again to remove the tool
when the collar is turned in the opposite direc-
tion.
Screwdriver Tools
When working with screwdriver bits 4, a univer-
sal bit holder 9 should always be used. Use only
screwdriver bits that fit the screw head.
Replacing the Drill Chuck (see figures
B–D)
Before any work on the power tool (e. g.,
maintenance, tool change, etc.) as well as
during transport and storage, set the rota-
tional direction switch to the center posi-
tion. Unintentional actuation of the On/Off
switch can lead to injuries.
The keyless chuck 1 is secured with a securing
screw 10 against unintentional loosening from
the drill spindle. Completely open the keyless
chuck 1 and unscrew the securing screw 10 in ro-
tation direction . Please note that the securing
screw has a left-hand thread.
Removing the Drill Chuck (see figure C)
Clamp the short end of a hex key 11 into the key-
less chuck 1.
Place the machine on a stable surface (e. g. a
workbench). Hold the machine firmly and loosen
the keyless chuck 1 by turning the hex key 11 in
rotation direction . Loosen a tight-seated key-
less chuck by giving the long end of the hex key
11 a light blow. Remove the hex key from the key-
less chuck and completely unscrew the keyless
chuck.
Mounting the Drill Chuck (see figure D)
The keyless chuck is mounted in reverse order.
Note: After mounting the keyless chuck, screw
the securing screw 10 back in again.
The drill chuck must be tightened with a
tightening torque of approx. 20–25 Nm.

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.
– 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 center
position in order to avoid unintentional starting.
Insert the charged battery 6 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.
