Noise/Vibration Information
Measured sound values determined according to EN 60745.
Typically the A-weighted noise levels of the product are:
Sound pressure level 89 dB(A); Sound power level
100 dB(A). Uncertainty K =3 dB.
Wear hearing protection!
Vibration total values a (triax vector sum) and uncertainty K
h
determined according to EN 60745:
2 2
a =5.5 m/s , K=2.5 m/s .
h
The vibration emission level given in this information sheet
has been measured in accordance with a standardised test
given in EN 60745 and may be used to compare one tool with
another. It may be used for a preliminary assessment of expo-
sure.
The declared vibration emission level represents the main ap-
plications of the tool. However if the tool is used for different
applications, with different accessories or poorly maintained,
the vibration emission may differ. This may significantly in-
crease the exposure level over the total working period.
An estimation of the level of exposure to vibration should also
take into account the times when the tool is switched off or
when it is running but not actually doing the job. This may sig-
nificantly reduce the exposure level over the total working pe-
riod.
Identify additional safety measures to protect the operator
from the effects of vibration such as: maintain the tool and the
accessories, keep hands warm, organise work patterns.

Assembly
Inserting a Router Bit (see figure A)
Before any work on the machine itself, pull the mains
plug.
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.
Bosch Power Tools
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.
– Fold the chip shield 6 down.
– Push the spindle lock lever 4 in clockwise direction and
hold it in this position ( ). If required, turn the motor spin-
dle by hand until it is locked.
– Loosen the tightening nut 23 with the open-end spanner
25 (size 24 mm) by turning in antclockwise direction ( ).
– 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 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 collet 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. 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.
Prevent dust accumulation at the workplace. Dusts can
easily ignite.
Mounting the Extraction Adapter
The extraction adapter 27 can be mounted with the hose con-
nection 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 adapt-
er 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 (accessory) into the
mounted extraction adapter. Connect the extraction hose 26
to a vacuum cleaner (accessory).
