Assembly
Battery Charging (see figure A)
 Use only the battery chargers listed on the accessories
page. Only these battery chargers are matched to the lith-
ium ion battery of your power tool.
Note: The battery is supplied partially charged. To ensure full
capacity of the battery, completely charge the battery in the
battery charger before using your power tool for the first time.
The Lithium-Ion battery can be charged at any time without
reducing its service life. Interrupting the charging procedure
does not damage the battery.
The Lithium-Ion battery is protected against deep discharging
by the "Electronic Cell Protection (ECP)". When the battery is
empty, the machine is switched off by means of a protective
circuit: The inserted tool no longer rotates.
 Do not continue to press the On/Off switch after the
machine has been automatically switched off. The bat-
tery can be damaged.
To remove the battery 5 press the unlocking buttons 4 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.
Observe the notes for disposal.
Changing the Tool (see figure B)
 Before any work on the machine itself (e. g. mainte-
nance, tool change, etc.) as well as during transport
and storage, remove the battery from the power tool.
There is danger of injury when unintentionally actuating
the On/Off switch.
The drill spindle is locked when the On/Off switch 7 is not
pressed. This makes quick, convenient and easy changing of
the tool in the drill chuck possible.
Open the keyless chuck 1 by turning in rotation direction ,
until the tool can be inserted. Insert the tool.
Firmly tighten the collar of the keyless chuck 1 by hand in ro-
tation direction .

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 lithium ion batteries with the
voltage listed on the nameplate of your power tool. Us-
ing other batteries can lead to injuries and pose a fire haz-
ard.
Note: Use of batteries not suitable for the machine can lead to
malfunctions of or cause damage to the power tool.
Set the rotational direction switch 6 to the centre position in
order to avoid unintentional starting. Insert the charged bat-
tery 5 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 6 is used to reverse the rota-
tional direction of the machine. However, this is not possible
with the On/Off switch 7 actuated.
Right Rotation: For drilling and driving in screws, push the
rotational direction switch 6 left to the stop.
Left Rotation: For loosening and unscrewing screws and
nuts, press the rotational direction switch 6 through to the
right stop.
Setting the torque
With the torque presetting ring 2 the required torque setting
can be preselected in 20 steps. With the correct setting, the
insert tool is stopped as soon as the screw is screwed flush in-
to the material or when the adjusted torque is reached. The
safety clutch is deactivated in the "
drilling.
Select a higher setting or switch to the "
screwing screws.
Gear selection, mechanical
 Actuate the gear selector 3 only when the machine is at
a standstill.
Two speed ranges can be preselected with the gear selector
3.
Gear I:
Low speed range; for screwdriving or working with large drill-
ing diameter.
Gear II:
High speed range; for working with small drilling diameter.
If the gear selector 3 cannot be pushed through to the stop,
lightly turn the drill chuck with drill.
Switching On and Off
To start the machine, press the On/Off switch 7 and keep it
pressed.
The power light 9 lights up when the On/Off switch 7 is slightly
or completely pressed, and allows the work area to be illumi-
nated when lighting conditions are insufficient.
To switch off the machine, release the On/Off switch 7.
To save energy, only switch the power tool on when using it.
