Inserting a Router Bit (see figure D)
f For inserting and changing router bits, it is
recommended to wear protective gloves.
Router bits get hot during routing.
Original router bits from the extensive Bosch ac-
cessories program are available at your special-
ist shop.
Only use clean router bits that are in perfect
condition.
– Push the spindle lock button 15 and keep it
pressed. If required, rotate the motor spindle
by hand until it locks.
– Loosen union nut 3 with open-end spanner 1
(size 17 mm) by turning toward n.
– Insert router bit 16 into collet 13 to the mark
on the router bit shank or until approx. 5 mm
of the router bit shank are still visible.
– Tighten union nut 3 with open-end spanner 1
(size 17 mm) by turning toward o.
– Release the spindle lock button.
f Do not tighten the tightening nut of the col-
let without a router bit inserted. Otherwise
the collet can be damaged.
Dust/Chip Extraction
f Dust from ceramic tiles (quartz dust) or nat-
ural stone (mineral dust) can be harmful to
one’s health. Contact with or inhaling the
dusts can trigger allergic reactions to the op-
erator or bystanders and/or lead to respira-
tory infections.
Certain dusts, such as quartz dust, are con-
sidered carcinogenic. Materials containing
asbestos may only be worked by specialists.
– As far as possible, use a dust extraction
system suitable for the material.
– 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.
Connecting the Dust Extraction (see figure E)
Mount the vacuum hose 17 (accessory) onto the
vacuum connection 4. Connect the vacuum hose
17 with 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 Holder with the Vacuum Hose to
the Retainer for the Hose Holder (see figure F)
Fasten holder 18 and vacuum hose 17 by insert-
ing them into the retainer for the hose holder
11.
Operation
Adjusting the Depth-of-cut
(see figure G)
f The adjustment of the depth-of-cut may on-
ly be carried out when the router is
switched off.
For adjustment of the depth-of-cut, proceed as
follows:
– Place the machine with the router bit mount-
ed on the workpiece to be machined.
– Loosen cutting depth adjustment knob 5, so
that footplate 7 can move freely.
– Adjust the desired routing depth by moving
the footplate 7 up or down.
– The application tool should project at least
5 mm above the workpiece.
– Tighten cutting depth adjustment knob 5.
– Check the carried out depth-of-cut adjust-
ment with a trial cut and correct it, if neces-
sary.
