Assembly
Battery Charging
A battery that is new or has not been used for a longer period
does not develop its full capacity until after approx. 5 charg-
ing/discharging cycles.
To remove the battery 9 press the unlocking buttons 8 and
pull out the battery downwards. Do not exert any force.
The battery is equipped with a NTC temperature control
which allows charging only within a temperature range of be-
tween 0 °C and 45 °C. A long battery service life is achieved
in this manner.
A significantly reduced working period after charging indi-
cates that the battery is used and must be replaced.
Observe the notes for disposal.
Changing the Tool (see figure A)
 Before any work on the machine (e. g., maintenance,
tool change, etc.) as well as during transport and stor-
age, set the rotational direction switch to the centre
position. Unintentional actuation of the On/Off switch can
lead to injuries.
Hold the rear sleeve 3 of the keyless chuck 1 tight and turn the
front sleeve 2 in rotation direction , until the tool can be in-
serted. Insert the tool.
Hold the rear sleeve 3 of the keyless chuck 1 tight and firmly
tighten the front sleeve 2 by hand in rotation direction , un-
til the locking action (click) is heard. The drill chuck is locked
automatically.
The locking is released again to remove the tool when the
front sleeve 2 is turned in the opposite direction.
Replacing the Drill Chuck
For machines without spindle lock, the drill chuck must be re-
placed through an authorized after-sales service agent for
Bosch power tools.

The drill chuck must be tightened with a tightening
torque of approx. 30–35 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. Touching or breathing-in the dusts can cause
allergic reactions 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 connection with wood-treat-
ment additives (chromate, wood preservative). Materials
containing 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 country for the
materials to be worked.
 Prevent dust accumulation at the workplace. Dusts can
easily ignite.
Operation
Starting Operation
Inserting the battery
 Use only original Bosch O-pack batteries with the volt-
age 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 11 to the centre position in
order to avoid unintentional starting. Insert the charged bat-
tery 9 into the handle so that it can be felt to engage and faces
flush against the handle.
Reversing the rotational direction (see figure B)
The rotational direction switch 11 is used to reverse the rota-
tional direction of the machine. However, this is not possible
with the On/Off switch 12 actuated.
Right Rotation: For drilling and driving in screws, push the
rotational direction switch 11 left to the stop.
The indicator for right rotation 5 lights up when the
On/Off switch 12 is actuated.
Left Rotation: For loosening or unscrewing screws, push the
rotational direction switch 11 right to the stop.
The indicator for left rotation 6 lights up when the
On/Off switch 12 is actuated.
Setting the torque
The required torque can be preselected in 10 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
material 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.
