and remove the depth stop 11. Press button 9
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 15 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.

tion Attachment (see figure G)
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 mov-
ability of the SDS-plus drilling tool can lead to in-
correct adjustment of the drilling depth.
Loosen the wing bolt 19 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 20 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 20 further over the telescopic pipe
18 of the dust extraction attachment than required,
so that as much as possible of the scale 18 on the
telescopic pipe remains visible.
Retighten the wing bolt 19 again. Loosen the
clamping screw 16 on the depth stop of the dust
extraction attachment.
Move the depth stop 17 on the telescopic pipe 18
in such a manner that the clearance X shown in
the figure corresponds with the required drilling
depth.
Tighten the clamping screw 16 in this position.
