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 cutters to control
horizontal cutting depth (Fig. 15). When
using these bits, neither the roller guide or
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. 16) 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.
