– Tighten the tightening nut 23 with the open-
end spanner 25 (size 24 mm) by turning in
clockwise direction. Release the spindle lock
lever 4.
– Fold the chip shield 6 up again.
Do not insert a router bit with a diameter
larger than 50 mm when the guide bushing
is not mounted. Such router bits do not fit
through the base plate.
Do not tighten the tightening nut of the col-
let without a router bit inserted. Otherwise
the collet can be damaged.
Dust/Chip Extraction (see figure B)
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 Extraction Adapter
The extraction adapter 27 can be mounted with
the hose connection to the front or to the rear.
When the guide bushing adapter 44 is mounted,
it is possible that the guide bushing adapter
must be turned by 180° so that the extraction
adapter 27 does not touch the release lever 46.
When mounting with the hose connection in
front, the chip shield 6 must be removed first.
Fasten the extraction adapter 27 with the
2 knurled screws 28 to the base plate 12.

Connecting the Dust Extraction
Insert an extraction hose ( Ø 35 mm) 26 (acces-
sory) into the mounted extraction adapter. Con-
nect the extraction hose 26 to a vacuum cleaner
(accessory).
The machine can be plugged directly into the re-
ceptacle of a Bosch all-purpose vacuum cleaner
with remote starting control. The vacuum clean-
er starts automatically when the machine is
switched on.
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.
Mounting the Chip Shield (see figure C)
Insert the chip shield 6 from the front into the
guide in such a manner that it engages. To re-
move the chip shield, grasp it by the sides and
pull it off toward the front.
Operation

Starting Operation

Observe correct mains voltage! The voltage
of the power source must agree with the
voltage specified on the nameplate of the
machine. Power tools marked with 230 V
can also be operated with 220 V.
Preselecting the Speed
The required speed can be preselected with the
thumbwheel 3 (also while running).
1 – 2 low speed
3 – 4 medium speed
5 – 6
high speed
The values shown in the chart are standard val-
ues. The necessary speed depends on the mate-
rial and the operating conditions, and can be de-
termined by practical testing.
