Replacing the Drill Chuck
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.
Removing the Securing Screw (see figure B)
The keyless chuck 1 is secured with a securing
screw 12 against unintentional loosening from
the drill spindle. Completely open the keyless
chuck 1 and unscrew the securing screw 12 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 13 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 13 in
rotation direction . Loosen a tight-seated key-
less chuck by giving the long end of the hex key
13 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 12 back in again.
The drill chuck must be tightened with a
tightening torque of approx. 35–40 Nm.
Dust/Chip Extraction
Dusts from materials such as lead-containing
coatings, some wood types, minerals and met-
al can be harmful to one's health. Touching or
breathing-in the dusts can cause allergic reac-
tions and/or lead to respiratory infections 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 containing
asbestos may only be worked by specialists.
1 609 929 M81 | (3.12.07)
– 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 9 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 9 is used to re-
verse the rotational direction of the machine.
However, this is not possible with the On/Off
switch 10 actuated.
Right Rotation: For drilling and driving in screws,
push the rotational direction switch 9 left to the
stop.
Left Rotation: For loosening or unscrewing
screws, push the rotational direction switch 9
right to the stop.
Setting the Torque
The required torque can be preselected in 25
steps with the torque preselection ring 4. 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 "Drilling" symbol.
