Note: If the tool holder was opened to the stop,
then the 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 21 once in the
opposite direction of the arrow. Afterwards, the
tool holder can be closed (tightened) again.
Turn the mode selector switch 11 to the "drill-
ing" position.
Removing Drilling Tools without SDS-plus
(GBH 2-26 DFR) (see figure I)
Firmly hold the retaining ring 22 of the quick
change chuck. Open the tool holder by turning
the front sleeve 21 in the direction of the arrow
until the tool can be removed.
Dust Extraction with the Dust
Extraction Attachment (Accessory)
Dusts from materials such as lead-containing
coatings, some wood types, minerals and
metal can be harmful to one's health. Touch-
ing or breathing-in the dusts can cause aller-
gic reactions and/or lead to respiratory infec-
tions of the user or bystanders.
Certain dusts, such as oak or beech dust, are
considered as carcinogenic, especially in
connection with wood-treatment additives
(chromate, wood preservative). Materials
containing asbestos may only be worked by
specialists.
– Use dust extraction whenever possible.
– Provide for good ventilation of the work-
ing place.
– It is recommended to wear a P2 filter-
class respirator.
Observe the relevant regulations in your
country for the materials to be worked.
Mounting the Dust Extraction Attachment
(see figure J)
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.
Bosch Power Tools
Press the button for depth stop adjustment 12
and remove the depth stop 13. Press button 12
again and insert the dust extraction attachment
into the auxiliary handle 14 from the front.
Connect an extraction hose (diameter 19 mm,
accessory) to the extraction sleeve 23 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
Extraction Attachment (see figure K)
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 mov-
ability of the SDS-plus drilling tool can lead to
incorrect adjustment of the drilling depth.
Loosen the wing bolt 27 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 28 of the dust ex-
traction 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 28 further over the
telescopic pipe 26 of the dust extraction attach-
ment than required, so that as much as possible
of the scale 26 on the telescopic pipe remains
visible.
Retighten the wing bolt 27 again. Loosen the
clamping screw 24 on the depth stop of the dust
extraction attachment.
Move the depth stop 25 on the telescopic pipe
26 in such a manner that the clearance X shown
in the figure corresponds with the required drill-
ing depth.
Tighten the clamping screw 24 in this position.
