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.
