Assembly
f Before any work on the machine itself, pull the mains
plug.
Inserting a Router Bit (see figure A)
f It is recommended to wear protective gloves when in-
serting or replacing router bits.
Depending on the application, router bits are available in the
most different designs and qualities.
Router bits made of high speed steel (HSS) are suitable for
the machining of soft materials, e. g. softwood and plastic.
Carbide tipped router bits (HM) are particularly suitable for
hard and abrasive materials, e. g. hardwood and aluminium.
Original router bits from the extensive Bosch accessories pro-
gram are available at your specialist shop.
Only use clean router bits that are in perfect condition.
– Press and hold the spindle lock button 9 (n). If required,
turn the spindle by hand until the lock engages.
Actuate the spindle lock button 9 only when at a stand-
still.
– Loosen the tightening nut 11 with the open-end spanner
21 (size 24 mm) by turning in antclockwise direction (o).
– Insert the router bit into the collet. The shank of the router
bit must be immersed at least 20 mm into the collet.
– Tighten the tightening nut 11 with the open-end spanner
21 (size 24 mm) by turning in clockwise direction. Release
the spindle lock button 9.
f 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.
f Do not tighten the tightening nut of the collet without a
router bit inserted. Otherwise the collet can be damaged.
Dust/Chip Extraction (see figure B)
f Dusts from materials such as lead-containing coatings,
some wood types, minerals and metal can be harmful to
one’s health. Touching or breathing-in the dusts can cause
allergic reactions and/or lead to respiratory infections of
the user or bystanders.
Certain dusts, such as oak or beech dust, are considered
as carcinogenic, especially in connection with wood-treat-
ment additives (chromate, wood preservative). Materials
containing asbestos may only be worked by specialists.
– As far as possible, use a dust extraction system suita-
ble for the material.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the
materials to be worked.
f Prevent dust accumulation at the workplace. Dusts can
easily ignite.
Mounting the Extraction Adapter
Before mounting the extraction adapter 24, bring the ma-
chine in the upper starting position by actuating the release
lever 16.
Insert the extraction adapter 24, turn the extraction adapter
24 clockwise to the stop until this can be felt to engage (bay-
onet catch), and fasten it with wing bolt 25.
Note: For router bit diam-
eters larger than 30 mm,
the insert 47 must be re-
moved from the extraction
adapter 24 by pressing on
the clamping shackles.
To ensure optimum ex-
traction, the extraction
adapter 24 must be
cleaned regularly.
Connecting the Dust Extraction
Insert an extraction hose (Ø 35 mm) 23 (accessory) into the
mounted extraction adapter. Connect the extraction hose 23
to a vacuum cleaner (accessory).
The machine can be plugged directly into the receptacle of a
Bosch all-purpose vacuum cleaner with remote starting con-
trol. The vacuum cleaner starts automatically when the ma-
chine is switched on.
The vacuum cleaner must be suitable for the material being
worked.
When vacuuming dry dust that is especially detrimental to
health or carcinogenic, use a special vacuum cleaner.
Operation
Starting Operation
f Observe correct mains voltage! The voltage of the pow-
er 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
17 (also while running).
1 – 2
low speed
3 – 4 medium speed
5 – 6 high speed
The values shown in the chart are standard values. The neces-
sary speed depends on the material and the operating condi-
tions, and can be determined by practical testing.
