USING SELF-PILOTED BITS

Self-piloted bits have an integral round tip or ball bearing which rides against the work surface above or below the cutter to control horizontal cutting depth (Fig. 17). When using these bits, neither the roller guide or the straight guide is required. When guiding against a laminated surface, use wax or other lubricant and do not apply excess pressure or the piloted end may mar the work. Bearing pilots must be kept clean and free of adhesive or other residue. Router bit bearings are sealed and permanently lubricated, and should be replaced when they no longer turn freely to avoid damaging the work surface.

PR003 ROLLER/BUSHING GUIDE

(Included with PR20EVSNK, also available as

optional accessory)

The optional PR003 Roller/Bushing Guide is used when edge-forming or trimming with unpiloted bits, non-bearing bits.

Attachment of Roller/Bushing Guide

The PR003 roller/bushing guide (Fig. 18) is attached using the wing screw and washer.

Adjustment of Roller/Bushing Guide Vertical Adjustment:

1.Loosen the wing screw and adjust up or down as necessary to allow roller/bushing to ride on the intended guiding surface.

2.Tighten wing screw.

Horizontal Adjustment:

Whether making straight or bevel cuts, the width of material removed is determined by the distance between the front of the router bit’s cutter and the front of the roller/bushing. Adjust the front of the roller/bushing as follows:

1.Loosen wing nut at bottom.

2.Rotate the wing nut on the back of the guide to move the roller/bushing in or out to create amount of cutter exposure needed to trim the laminate flush with the guiding surface or to create the desired bevel.

3.Be sure the bit clears the top of the roller/bushing guide by at least 1/8" (3 mm) to avoid damage.

4.Tighten wing nut on the bottom of the guide assembly

5.Make a trial cut to check the setting and readjust as necessary.

Use of the Roller/Bushing Guide

1.With the guide installed and adjusted, the router should be fed normally, keeping the guide in contact with the edge of the workpiece at all times.

2.To maintain a consistent width of cut, a consistent angle must be maintained between the router and the workpiece.
