– Hold the rear sleeve of the keyless chuck (20) and firmly
tighten the front sleeve by hand in a clockwise direction
until it stops clicking. This will automatically lock the drill
chuck.
– Check that it is seated securely by pulling the tool.
Note: If the tool holder was unscrewed all the way, a scrap-
ing sound may be heard while retightening the tool holder
and it may not fully tighten.
In this case, turn the front sleeve (21) anti-clockwise by one
turn. This will allow the tool holder to be fully tightened.
– Turn the impact/mode selector switch (4) to the "drilling"
position.
Removing application tools that do not have SDS-Quick
(see figure F)
Hold the rear sleeve (22) of the keyless chuck firmly and
turn the front sleeve (21) of the keyless chuck anti-clock-
wise until the application tool can be removed.

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
Start-up
Inserting the Battery
Use only original Bosch lithium-ion batteries with the
u
voltage stated on the type plate of your power tool.
Using other batteries can lead to injuries and pose a fire
hazard.
– Set the rotational direction switch (8) to the middle posi-
tion to avoid unintentionally switching it on.
– Slide the battery (10) all the way into the battery bay
(18).
Setting the Operating Mode
The operating mode of the power tool is selected using the
impact/mode selector switch (4).
Note: Only change the operating mode when the power
u
tool is switched off. Otherwise, the power tool may be-
come damaged.

– To change the operating mode, turn the impact/mode se-
lector switch (4) to the required position.
Position for hammer drilling into concrete,
brick or stone
Position for drilling without impact in wood
and metal
Position for screwdriving
Setting the rotational direction (see figure G)
Only operate the rotational direction switch (8) when
u
the power tool is not in use.
The rotational direction switch (8) is used to change the ro-
tational direction of the power tool. However, this is not pos-
sible while the on/off switch (9) is being pressed.
– Right rotation: To drill and to drive in screws, press the
rotational direction switch (8) through to the left stop.
The rotational direction indicator for right rotation
(5) lights up when the on/off switch (9) is pressed
and the motor is running.
– Left rotation: To loosen and unscrew screws and nuts,
press the rotational direction switch (8) through to the
right stop.
The rotational direction indicator for left rotation
(7) lights up when the on/off switch (9) is pressed
and the motor is running.

Switching On/Off

– To start the power tool, press and hold the on/off switch
(9).
The lamp (11) lights up when the on/off switch (9) is lightly
or fully pressed, meaning that the work area is illuminated in
poor lighting conditions.
For low temperatures, the power tool reaches the full ham-
mer/impact capacity only after a certain time.
– To switch off the power tool, release the on/off switch
(9).
Adjusting the Speed/Impact Rate
– Adjust the speed/impact rate of the power tool when it is
on by pressing in the on/off switch (9) to varying extents.
Applying light pressure to the on/off switch (9) results in a
low rotational speed/impact rate. Applying increasing pres-
sure to the switch increases the speed/impact rate.

Practical Advice

Only apply the power tool to the screw/nut when the
u
tool is switched off. Rotating tool inserts can slip off.
