Changing the tool (see figure B)
Before any work on the power tool (e.g. maintenance,
u
tool change, etc.) as well as during transport and stor-
age, set the rotational direction switch to the middle
position. There is risk of injury from unintentionally
pressing the on/off switch.
The drill spindle is locked when the on/off switch (7) is not
pressed. This makes it possible to change the application
tool in the drill chuck quickly, conveniently and easily.
Open the keyless chuck (1) by turning it in the direction of
rotation ➊ until the tool can be inserted. Insert the tool.
Firmly tighten the sleeve of the keyless chuck (1) by turning
it by hand in the direction of rotation ➋ until it audibly clicks
into place. This will automatically lock the drill chuck.
The lock will disengage again if you turn the sleeve in the op-
posite direction to remove the tool.

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 carci-
nogenic, especially in connection with wood-treatment ad-
ditives (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 ma-
terials to be worked.
Avoid dust accumulation at the workplace. Dust can
u
easily ignite.
Operation

Starting Operation

Set the rotational direction (see figure C)
The rotational direction switch (4) is used to change the ro-
tational direction of the power tool. However, this is not pos-
sible while the on/off switch (7) is being pressed.
Right rotation: To drill and to drive in screws, press the ro-
tational direction switch (4) through to the left stop.
The rotational direction indicator for right rotation
(2) lights up when the on/off switch (7) is pressed
and the motor is running.
Left Rotation: To loosen and unscrew screws and nuts,
press the rotational direction switch (4) through to the right
stop.
The rotational direction indicator for left rotation
(3) lights up when the on/off switch (7) is pressed
and the motor is running.

Switching on/off
To start the power tool, press and hold the on/off switch
(7).
The lamp (5) lights up when the on/off switch (7) is lightly or
fully pressed, meaning that the work area is illuminated in
poor lighting conditions.
To switch off the power tool, release the on/off switch (7).
Adjusting the Speed
You can adjust the speed of the power tool when it is on by
pressing in the on/off switch (7) to varying extents.
A light pressure on the on/off switch (7) results in a low rota-
tional speed. Increased pressure on the switch causes an in-
crease in speed.
Fully automatic spindle lock (Auto-Lock)
The drill spindle, and therefore the tool holder, are locked
when the on/off switch (7) is not pressed.
This allows screws to be driven in even when the battery is
discharged and enables the power tool to be used as a
screwdriver.
Run-out brake
Upon releasing the on/off switch (7), the drill chuck is
slowed down, which prevents the application tool from con-
tinuing to rotate.
When driving in screws, you should therefore only release
the on/off switch (7) once the screw has been inserted flush
into the workpiece. This way, the head of screw will not pen-
etrate the workpiece.
Battery Charge Indicator
When the on/off switch (7) is pressed in halfway or com-
pletely, the battery charge indicator (6) indicates the bat-
tery's state of charge for several seconds. The indicator con-
sists of three green LEDs.
LED
Continuous lighting 3 x green
Continuous lighting 2 x green
Continuous lighting 1 x green
Flashing light 1 x green
Temperature-dependent overload protection
In normal conditions of use, the power tool cannot be over-
loaded. If the power tool is overloaded or the permitted bat-
tery temperature is exceeded, the electronics of the power
tool will switch off until the temperature returns to within the
optimum operating temperature range.

Practical advice

Only apply the power tool to the screw when the tool
u
is switched off. Rotating application tools can slip off.
After working at a low speed for an extended period, you
should operate the power tool at the maximum speed for ap-
proximately three minutes without load to cool it down.
When drilling into metal, only use sharpened HSS drills (HSS
= high-speed steel) which are in perfect condition. The
Bosch accessory range guarantees appropriate quality.
