– Release the spindle lock button.
– If required, clean all parts to be mounted prior to assem-
bling, using a soft brush or by blowing out with com-
pressed air.
– Start the new tightening nut on tool holder 14.
– Hand-tighten the tightening nut.
Do not tighten the tightening nut of the collet without a
router bit inserted. Otherwise the collet can be damaged.
Inserting a Router Bit (see figures C–D)
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.
– Push the spindle lock button 9 and keep it pressed. If re-
quired, rotate the motor spindle by hand until it locks.
– Loosen the tightening nut 5 with the open-end spanner by
turning in anticlockwise direction 15.
– Insert the router bit into the collet. The shank of the router
bit must be immersed at least 20 mm into the collet.
– Retighten the tightening nut by turning in clockwise direc-
tion.
– Release the spindle lock button.
Do not tighten the tightening nut of the collet without a
router bit inserted. Otherwise the collet can be damaged.
Mounting the Routing Base (see figure E)
For routing, the routing base 2 must be mounted on the motor
unit 1 again.
– Release clamping lever 10, if tightened.
– Bring the two double arrows on the motor unit and the
routing base 2 into alignment.
– Push the motor unit into the routing base and turn the mo-
tor unit in clockwise direction until the
against the symbol.
– Push the motor unit further into the routing base.
– After mounting is completed, turn the
ing base to the symbol on the motor unit.
– Lock the clamping lever.
After mounting, always check if the motor unit is seat-
ed tightly in the routing base.
If required, change the pre-tension of the clamping lever 10
(see "Readjusting the Clamping Lever", page 17).

Dust/Chip Extraction

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.
Operation
Adjusting the Depth-of-cut (see figure F)
The adjustment of the depth-of-cut may only be carried
out when the router is switched off.
For coarse adjustment of the depth-of-cut, proceed as fol-
lows:
– Place the machine with the router bit mounted on the
workpiece to be machined.
– Release clamping lever 10, if tightened.
– Turn the routing base 2 so that the
the symbol and slowly lower the motor unit until the
router bit touches the workpiece.
– Lock the clamping lever.
– Read the measuring value off the scale 8 and note it down
(zeroing). Add the desired depth-of-cut to this value.
– Open the clamping lever and adjust the motor unit to the
calculated scale value.
– Turn the routing base so that the
the symbol and lock the clamping lever again.
– Check the carried out depth-of-cut adjustment with a trial
cut and correct it, if necessary.
For fine adjustment of the depth-of-cut, proceed as follows:
– With the clamping lever 10 open, turn the routing base so
that the
– Adjust the desired depth-of-cut with thumbwheel 3.
– Lock the clamping lever.

Starting Operation

Observe correct mains voltage! The voltage of the pow-
mark points 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.

To start the machine, set the On/Off switch 11 to I.
To switch off the machine, set the On/Off switch 11 to 0.

Working Advice

Protect router bits against shock and impact.
Shaping or Molding Applications (see figure G)
For shaping or molding applications without the use of a par-
allel guide, the router bit must be equipped with a pilot or a
ball bearing.
– Guide the switched on power tool from the side toward the
workpiece until the pilot or the ball bearing of the router bit
faces against the workpiece edge to be machined.
– Guide the machine alongside the workpiece edge. Ensure
rectangular support. Excessive pressure can damage the
edge of the workpiece.
