 Prevent dust accumulation at the workplace. Dusts can
easily ignite.
Mounting the Dust Extraction Attachment (see figure H)
For dust extraction, the dust extraction attachment (accesso-
ry) is required. When drilling, the dust extraction attachment
retracts so that the attachment head is always close to the
surface at the drill hole.
– Press the button for depth stop adjustment 10 and remove
the depth stop 1. Press button 10 again and insert the dust
extraction attachment into the auxiliary handle 17 from the
front.
– Connect an extraction hose (diameter 19 mm, accessory)
to the extraction sleeve 21 of the dust extraction attach-
ment.
The vacuum cleaner must be suitable for the material being
worked.
When vacuuming dry dust that is especially detrimental to
health or carcinogenic, use a special vacuum cleaner.
Adjusting the Drilling Depth on the Dust Extraction At-
tachment (see figure I)
The required drilling depth X can also be adjusted when the
dust extraction attachment is mounted.
– Insert the SDS-plus drilling tool to the stop into the SDS-
plus tool holder 2. Otherwise, the movability of the SDS-
plus drilling tool can lead to incorrect adjustment of the
drilling depth.
– Loosen the wing bolt 25 on the dust extraction attach-
ment.
– Without switching the power tool on, apply it firmly to the
drilling location. The SDS-plus drilling tool must face
against the surface.
– Position the the guide pipe 26 of the dust extraction at-
tachment in its holding fixture in such a manner that the
head of the dust extraction attachment faces against the
surface to be drilled. Do not slide the guide pipe 26 further
over the telescopic pipe 24 of the dust extraction attach-
ment than required, so that as much as possible of the
scale 24 on the telescopic pipe remains visible.
– Retighten the wing bolt 25 again. Loosen the clamping
screw 22 on the depth stop of the dust extraction attach-
ment.
– Move the depth stop 23 on the telescopic pipe 24 in such
a manner that the clearance X shown in the figure corre-
sponds with the required drilling depth.
– Tighten the clamping screw 22 in this position.
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
to protect the power tool against accidental starting.
1 619 92A 069 | (16.10.13)
– Insert the charged battery 12 from the front into the base
of the power tool. Push the battery completely into the
base until the red stripe can no longer be seen and the bat-
tery is securely locked.
Setting the operating mode
With the selector switch for drilling/hammer drilling 9, the op-
erating mode of the machine is selected.
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" 9 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 J)
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: Push the rotational direction switch 7 left
to the stop.
Left rotation: Push the rotational direction switch 7 right
to the stop.
For hammer drilling and drilling, always set the direction of ro-
tation to right rotation.
Switching On and Off
– To start the machine, press the On/Off switch 8.
When starting the machine for the first time, a starting delay
is possible, as the electronic system of the power tool has to
configure itself first.
To save energy, only switch the power tool on when using it.
– To switch off the machine, release the On/Off switch 8.
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.
Safety Clutch
 If the tool insert becomes caught or jammed, the drive
to the drill spindle is interrupted. Because of the forces
that occur, always hold the power tool firmly with both
hands and provide for a secure stance.
 If the power tool jams, switch the machine off and loos-
en the tool insert. When switching the machine on with
the drilling tool jammed, high reaction torques can oc-
cur.
