Due to their working principle, SDS-Quick drilling tools move
freely. This results in radial run-out at no-load. However, this
has no effect on the accuracy of the drill hole, as the drill bit
centres itself during drilling.
The SDS-Quick tool holder can also accommodate different
drill-bit types with hexagon shank. For more information, see
the accessories page at the end of these operating instruc-
tions.
The dust protection cap 2 largely prevents the entry of drilling
dust into the tool holder during operation. When inserting the
tool, take care that the dust protection cap 2 is not damaged.
 A damaged dust protection cap should be changed im-
mediately. We recommend having this carried out by
an after-sales service.
Inserting SDS-Quick Drilling Tools (see figure B)
Clean and lightly grease the shank end of the tool.
Insert the tool in a twisting manner into the tool holder until it
latches itself.
Check the latching by pulling the tool.
Removing SDS-Quick Drilling Tools (see figure C)
Push back the locking sleeve 3 and remove the tool.

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.
Set the rotational direction switch 7 to the centre position in
order to avoid unintentional starting. Insert the charged bat-
tery 10 into the handle so that it can be felt to engage and fac-
es flush against the handle.
Setting the operating mode
With the selector switch for drilling/hammer drilling 4, the op-
erating mode of the machine is selected.
1 609 92A 09P | (28.5.13)
Note: Change the operating mode only when the machine is
switched off! Otherwise, the machine can be damaged.
To change the operating mode, turn the selector switch for
"drilling/hammer drilling" 4 to the requested position.
Position for hammer drilling in concrete or
stone
Position for drilling without impact in wood,
metal, ceramic and plastic as well as for
screwdriving
Reversing the rotational direction (see figure D)
 Actuate the rotational direction switch 7 only when the
machine is at a standstill.
The rotational direction switch 7 is used to reverse the rota-
tional direction of the machine. However, this is not possible
with the On/Off switch 8 actuated.
Right Rotation: For drilling and driving in screws, push the
rotational direction switch 7 left to the stop.
The indicator for right rotation 5 lights up when the
On/Off switch 8 is actuated and the motor is running.
Left Rotation: For loosening and unscrewing screws and
nuts, press the rotational direction switch 7 through to the
right stop.
The indicator for left rotation 6 lights up when the
On/Off switch 8 is actuated and the motor is running.
Switching On and Off
To start the machine, press the On/Off switch 8 and keep it
pressed.
The power light 11 lights up when the On/Off switch 8 is
slightly or completely pressed, and allows the work area to be
illuminated when lighting conditions are insufficient.
To switch off the machine, release the On/Off switch 8.
For low temperatures, the power tool reaches the full ham-
mer/impact capacity only after a certain time.
To save energy, only switch the power tool on when using it.
Setting the Speed/Impact Rate
The speed/impact rate of the switched on power tool can be
variably adjusted, depending on how far the On/Off switch 8
is pressed.
Light pressure on the On/Off switch 8 results in low speed/im-
pact rate. Further pressure on the switch increases the
speed/impact rate.
Run-on Brake
When the On/Off switch 8 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 8.
By doing so, the head of the screw does not penetrate into the
material.
