SELECTING BITS

Your Bosch palm router is designed for a wide variety of routing applications that use 1/4" shank bits. These include woodworking applications such as edge forming, grooving, and sign making. This router is also ideal for trimming laminates, phenolics, and other materials that have been bonded to a substrate overhang the substrate typically by about 1/8" (3 mm).

A wide assortment of router bits with different profiles are available as accessories. Only use good quality bits.

To prevent personal injury, ! WARNING always remove the plug

from power source before removing or in- stalling bits or accessories.

Installing a Router Bit *

1.Lay the router or motor on its side (unless router is in the plunge-base router configuration). The router can also be stood "on its head" for bit changes, such as when in the plunge-base configuration.

2.Press spindle lock to prevent rotation of collet chuck. NOTE: it may be necessary to rotate collet nut to engage spindle lock (Fig. 3).

3.Next, use the collet wrench to loosen the collet chuck assembly in a counter-clockwise direction (viewed from bottom of router).

4.Insert the shank of the router bit into the collet chuck assembly as far as it will go, then back the shank out until the cutters are approximately 1/8" to 1/4" away from the collet nut face.

5.With the router bit inserted and the spindle lock engaged, use the collet wrench to firmly tighten the collet chuck assembly in a clockwise direction (viewed from bottom of router) (Fig. 4).

To ensure proper gripping of the router bit and minimize run-out, the shank of the router bit must be inserted at least 5/8".

Cutter diameter must be at least 1/4” smaller than

opening for the bit and cutter.

! CAUTION	To prevent damage to tool,
	do not tighten collet without
a bit.

(BASE REMOVED FOR CLARITY)

*As an alternative to the spindle lock, the thin 10mm wrench can be used on the ‘flats’ of the spindle.

NOTE: The bit shank and chuck should be clean and free of dust, wood, residue and grease before assembling.

Removing the Router Bit*

1.Press spindle lock to prevent rotation of collet chuck, and turn the collet chuck assembly in a counter-clockwise direction.

2.Once the collet chuck assembly is loosened, continue to turn the collet chuck assembly until it pulls the collet free from the spindle, and the router bit can be removed.

NOTE: The collet chuck is self-extracting; it is NOT necessary to strike the collet chuck to free the router bit.
