Inserting Drilling Tools without SDS-plus
(see figure F)
Note:
Do not use tools without SDS-plus for ham-
mer drilling or chiselling! Tools without SDS-plus
and their drill chucks are damaged by hammer
drilling or chiselling.
Insert a key type drill chuck
12
(see “Changing
the Key Type Drill Chuck”, page 20).
Open the key type drill chuck
12
by turning until
the tool can be inserted. Insert the tool.
Insert the chuck key into the corresponding holes
of the key type drill chuck
12
and clamp the tool
uniformly.
Turn the mode selector switch
7
to the “drilling”
position.
Removing Drilling Tools without SDS-plus
(see figure G)
Turn the sleeve of the key type drill chuck
12
with
the drill chuck key in anticlockwise direction until
the drilling tool can be removed.
Dust Extraction with the Dust Extraction
Attachment (Accessory)
Mounting the Dust Extraction Attachment
(see figure H)
For dust extraction, the dust extraction attach-
ment (accessory) 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
8
and remove the depth stop
11
. Press button
8
again and insert the dust extraction attachment
into the auxiliary handle
10
from the front.
Connect an extraction hose (diameter 19 mm,
accessory) to the extraction sleeve
13
of the dust
extraction attachment.
The vacuum cleaner must be suitable for the ma-
terial being worked.
When vacuuming dry dust that is especially detri-
mental to health or carcinogenic, use a special
vacuum cleaner.
Adjusting the Drilling Depth on the Dust Extrac-
tion Attachment (see figure I)
The required drilling depth
X
can also be adjust-
ed when the dust extraction attachment is
mounted.
Insert the SDS-plus drilling tool to the stop into
the SDS-plus tool holder
1
. Otherwise, the mova-
bility of the SDS-plus drilling tool can lead to in-
correct adjustment of the drilling depth.
Loosen the wing bolt
17
on the dust extraction
attachment.
Without switching the power tool on, apply it
firmly to the drilling location. The SDS-plus drill-
ing tool must face against the surface.
Position the the guide pipe
18
of the dust extrac-
tion attachment in its holding fixture in such a
manner that the head of the dust extraction at-
tachment faces against the surface to be drilled.
Do not slide the guide pipe
18
further over the
telescopic pipe
16
of the dust extraction attach-
ment than required, so that as much as possible
of the scale
16
on the telescopic pipe remains
visible.
Retighten the wing bolt
17
again. Loosen the
clamping screw
14
on the depth stop of the dust
extraction attachment.
Move the depth stop
15
on the telescopic pipe
16
in such a manner that the clearance
X
shown in
the figure corresponds with the required drilling
depth.
Tighten the clamping screw
14
in this position.
