Removing the Fixed Routing Base (see figure A)
Before fitting a router bit, you must first separate the fixed
routing base (2) from the motor unit (1).
Open the clamping lever (10) and turn the fixed routing
base (2) until the rib (47) in the fixed routing base matches
the depth adjustment channel (48) on the motor unit.
Pull the motor unit (1) up and out of the fixed routing
base (2).
Changing the collet (see figure B)
Depending on the router bit used, you may have to change
the cap nut with the collet (6) before fitting the router bit.
If the right collet for your router bit is already fitted, please
follow the work steps in the following section.
The collet (15) must sit in the cap nut with a small amount of
play. The cap nut (6) must be easy to fit. If the cap nut or col-
let is damaged, replace it immediately.

Fitting the router bit (see figures C–D)
Wearing protective gloves while fitting and changing
u
router bits is recommended.
Router bits are available in a wide variety of designs and
qualities depending on the intended application.
Router bits made of high-performance high-speed steel
(HSS) are suited to machining soft materials such as soft-
wood and plastic.
Router bits with carbide tips are especially suitable for
hard and abrasive materials such as hardwood and alu-
minium.
Original router bits from the extensive range of Bosch ac-
cessories are available from your specialist dealer.
Only use undamaged and clean router bits.

To start routing, the fixed routing base (2) must be fitted
back onto the motor unit (1).
Open the clamping lever (10) if it is closed.
Align the rib (47) in the fixed routing base (2) with the depth
adjustment channel (48) of the motor unit (1).
Slide the motor unit into the fixed routing base until roughly
the required cutting depth is reached. Then turn the fixed
routing base (2) clockwise as far as it will go in order to ac-

Dust/Chip Extraction
The dust from materials such as lead paint, some types of
wood, minerals and metal can be harmful to human health.
Touching or breathing in this dust can trigger allergic reac-
tions and/or cause respiratory illnesses in the user or in
people in the near vicinity.
Certain dusts, such as oak or beech dust, are classified as
carcinogenic, especially in conjunction with wood treatment
additives (chromate, wood preservative). Materials contain-
ing asbestos may only be machined by specialists.
– Use a dust extraction system that is suitable for the ma-
terial wherever possible.
– Provide good ventilation at the workplace.
– It is advisable to wear a P2 filter class breathing mask.
The regulations on the material being machined that apply in
the country of use must be observed.
Avoid dust accumulation at the workplace. Dust can
u
easily ignite.
