Note: If the tool holder was opened to the stop,
then a latching noise possibly may be heard
while closing the tool holder and the tool holder
will not close.
In this case, turn the front sleeve 25 once in an-
ticlockwise direction. Afterwards, the tool hold-
er can be closed (tightened).
– Turn the mode selector switch 12 to the
"drilling" position.
Removing Drilling Tools without SDS-plus from
the Keyless Chuck
(PBH 2900 FRE/PBH 3000 FRE Set/
PBH 3000-2 FRE) (see figure J)
– Firmly hold the rear sleeve 26 of the keyless
chuck and turn the front sleeve 25 of the key-
less chuck in anticlockwise direction until
the drilling tool can be removed.
Dust Extraction with the Dust Extrac-
tion Attachment (Accessory)
Mounting the Dust Extraction Attachment
(see figure K)
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
15 and remove the depth stop 18. Press but-
ton 15 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
27 of the dust extraction attachment.
The vacuum cleaner must be suitable for the ma-
terial being worked.
When vacuuming dry dust that is especially det-
rimental to health or carcinogenic, use a special
vacuum cleaner.

Adjusting the Drilling Depth on the Dust Ex-
traction Attachment (see figure L)
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 3. Otherwise,
the movability of the SDS-plus drilling tool
can lead to incorrect adjustment of the drill-
ing depth.
– Loosen the wing bolt 31 on the dust extrac-
tion attachment.
– 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 32 of the dust ex-
traction attachment in its holding fixture in
such a manner that the head of the dust ex-
traction attachment faces against the surface
to be drilled. Do not slide the guide pipe 32
further over the telescopic pipe 30 of the
dust extraction attachment than required, so
that as much as possible of the scale 30 on
the telescopic pipe remains visible.
– Retighten the wing bolt 31 again. Loosen the
clamping screw 28 on the depth stop of the
dust extraction attachment.
– Move the depth stop 29 on the telescopic
pipe 30 in such a manner that the
clearance X shown in the figure corresponds
with the required drilling depth.
– Tighten the clamping screw 28 in this posi-
tion.
