The power tool cannot be used during the charge procedure;
it is not defective when inoperative during the charging proce-
dure.
Observe the notes for disposal.
Changing the Tool (see figure B)
 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.
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 . This automatically locks the drill chuck.
The locking is released again to remove the tool when the col-
lar is turned in the opposite direction.

Dust/Chip Extraction

 Dust 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 dust can cause
allergic reactions and/or lead to respiratory infections of
the user or bystanders.
Certain dust, such as oak or beech dust, is considered car-
cinogenic, especially in connection with wood-treatment
additives (chromate, wood preservative). Materials con-
taining 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. Dust can
easily ignite.
Operation

Starting Operation

To save energy, only switch the power tool on when using it.
Reversing the rotational direction (see figure C)
The rotational direction switch 4 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 4 left to the stop.
The indicator for right rotation 2 lights up when the
On/Off switch 7 is actuated and the motor is running.
Left Rotation: For loosening and unscrewing screws and
nuts, press the rotational direction switch 4 through to the
right stop.
The indicator for left rotation 3 lights up when the
On/Off switch 7 is actuated and the motor is running.
Bosch Power Tools
Switching On and Off
To start the machine, press the On/Off switch 7 and keep it
pressed.
The power light 5 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.
Adjusting the Speed
The speed of the switched-on power tool can be variably ad-
justed, depending on how far the On/Off switch 7 is pressed.
Light pressure on the On/Off switch 7 results in a low rotation-
al speed. Further pressure on the switch results in an increase
in speed.
Fully automatic spindle locking (Auto-lock)
When the On/Off switch 7 is not pressed, the drill spindle and
thus the tool holder are locked.
This enables screws to be screwed in, even when the battery
is empty and allows for the machine to be used as a screwdriv-
er.
Run-on Brake
When the On/Off switch 7 is released, the chuck brakes to a
stop, thus preventing the run-on of the tool.
When driving in screws, wait until the screw is screwed in
flush with the material and then release the On/Off switch 7.
By doing so, the head of the screw does not penetrate into the
material.
LED Capacity
Continuous lighting 3 x green ≥ 2/3
Continuous lighting 2 x green ≥ 1/3
Continuous lighting 1 x green < 1/3
Flashing light 1 x green Reserve
Temperature Dependent Overload Protection
When using as intended for, the power tool cannot be subject
to overload. When the load is too high or the allowable battery
temperature is exceeded, the electronic control switches off
the power tool until the temperature is in the optimum tem-
perature range again.

Working Advice

 Apply the power tool to the screw only when it is
switched off. Rotating tool inserts can slip off.
After longer periods of working at low speed, allow the ma-
chine to cool down by running it for approx. 3 minutes at max-
imum speed with no load.
For drilling in metal, use only perfectly sharpened HSS drill
bits (HSS=high-speed steel). The appropriate quality is guar-
anteed by the Bosch accessories program.
Before screwing larger, longer screws into hard materials, it is
advisable to predrill a pilot hole with the core diameter of the
2
thread to approx. / of the screw length.
