– As far as possible, use a dust extraction sys-
tem suitable for the material.
– Provide for good ventilation of the working
place.
– It is recommended to wear a P2 filter-class res-
pirator.
Observe the relevant regulations in your country
for the materials to be worked.
Mounting the Dust Extraction Attachment
(see figure G)
For dust extraction, the dust extraction attachment
(accessory) is required. When drilling, the dust ex-
traction 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, ac-
cessory) to the extraction sleeve 21 of the dust ex-
traction attachment.
The vacuum cleaner must be suitable for the mate-
rial being worked.
When vacuuming dry dust that is especially detri-
mental to health or carcinogenic, use a special vac-
uum cleaner.
Adjusting the Drilling Depth on the Dust Extrac-
tion Attachment (see figure H)
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 ad-
justment of the drilling depth.
Loosen the wing bolt 25 on the dust extraction at-
tachment.
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 extrac-
tion attachment in its holding fixture in such a man-
ner 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 attachment 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 attachment.
Move the depth stop 23 on the telescopic pipe 24
in such a manner that the clearance X shown in the
figure corresponds with the required drilling depth.
Tighten the clamping screw 22 in this position.

Operation
Starting Operation
Inserting the battery
 Use only original BTI lithium-ion batteries with
the voltage listed on the nameplate of your
power tool. Using other batteries can lead to in-
juries and pose a fire hazard.
Set the rotational direction switch 7 to the centre
position to protect the power tool against acciden-
tal starting.
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 battery is securely locked.
Setting the operating mode
With the selector switch for drilling/hammer drilling
9, the operating 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 re-
quested position.
Position for hammer drilling in con-
crete or stone
Position for drilling without impact in
wood, metal, ceramic and plastic as
well as for screwdriving
Reversing the rotational direction (see figure I)
The rotational direction switch 7 is used to reverse
the rotational direction of the machine. However,
this is not possible with the On/Off switch 8 actuat-
ed.
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 di-
rection of rotation to right rotation.
Switching On and Off
To save energy, only switch the power tool on
when using it.
To start the machine, press the On/Off switch 8.
When starting the machine for the first time, a start-
ing delay is possible, as the electronic system of
the power tool has to configure itself first.
To switch off the machine, release the On/Off
switch 8.
