INSTALLING A ROUTER BIT

Place router upside down or lay router on its side with the base resting on the bench. Another option is to remove the motor from the base before installing the bit.

1.Remove the chip shield (or flip up if plunge base is attached.

2.Hold the armature shaft in place with the shaft wrench (Fig. 4)

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

To tighten or loosen collet nut, hold both wrenches in one hand and and squeeze the wrenches together.

When the templet guide ! WARNING has been removed from

base, do not use router bits greater than 2" in diameter as they will not fit through the sub-base.

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

4.Once you have verified that the bit's shank is of the proper diameter for the collet to be used, 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 shaft wrench holding the armature shaft, use the collet wrench to firmly tighten the collet chuck assembly in a clockwise direction (viewed from under the 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".

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.Use the shaft and collet chuck wrenches as described earlier, 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.

COLLET CHUCK CARE

With the router bit removed, continue to turn the collet chuck counter-clockwise until it is free of the shaft. To assure a firm grip, occasionally blow out the collet chuck with compressed air, and clean the taper in the armature assembly shaft with a tissue or fine brush. The collet chuck is made up of two component parts as illustrated (Fig. 5); check to see that the collet is properly seated in the collet chuck nut and lightly thread the collet

chuck back onto the armature shaft. Replace worn or damaged collet chucks immediately.
