# Changing the tool

- Wearing protective gloves while fitting and changing router bits is recommended.

Original router bits from the extensive range of Bosch accessories are available from your specialist dealer.

##

Before fitting a router bit, you must first separate the routing base (2) from the drive unit (1).

Open the wing bolt (12) on the routing base (2).

Pull the drive unit out in an upward direction.

##

Depending on the router bit used, you may have to change the cap nut with the collet (8) 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 (16) must sit in the cap nut with a small amount of play. The cap nut (8) must be easy to fit. If the cap nut or collet is damaged, replace it immediately.

Place the open-ended spanner (18) on the tool holder (17) (see figure C1).

Unscrew the cap nut (8) anticlockwise using the open-ended spanner (19).

If required, clean all the parts you want to fit with a soft brush or by blowing them clean with compressed air before assembling them.

Place the new cap nut on the tool holder (17).

Loosely tighten the cap nut.

- Do not, under any circumstances, tighten the collet with the tightening nut until a router bit has been fitted. The collet may otherwise become damaged.

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 softwood and plastic.

Router bits with carbide tips (HM) are especially suitable for hard and abrasive materials such as hardwood and aluminium.

Original router bits from the extensive range of Bosch accessories are available from your specialist dealer.

Only use undamaged and clean router bits.

To start routing, the routing base (2) must be fitted back onto the drive unit (1).

Open the wing bolt (12) on the routing base (2).

Slide the drive unit (1) into the routing base (2).

Close the wing bolt (12) on the routing base (2).

Note: The wing bolt (12) and the knurled screw (6) can be exchanged with each other.

- After assembly, always check that the drive unit is firmly seated in the routing base.
