SELECTING BITS

A wide assortment of router bits with different profiles are available as accessories. Use 1/2" shank whenever possible, and only use good quality bits.

To prevent personal injury, ! WARNING always remove the plug from

power source before removing or installing bits or accessories.

INSTALLING A ROUTER BIT

1.Lay router on its side with the flat side of base resting on the bench.

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 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).

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 the

opening for the bit and cutter.

For use with larger bits, see “Preparation for use with Bosch Router Table” on page 17.

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

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 its taper, 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.
