loosely attach the rectangular nut. See
Fig. 2. The raised rim on the nut should
face toward the mounting bracket. Now
slide the thin washer and rectangular nut
into the T-slot on the back of the Incra

Attach the Incra Fence

To achieve a silky smooth

carriage motion when moving the

fence, it is important that your table
surface is flat and smooth. If you find
that your carriage tends to bind slightly
during some portion of its travel, try
loosening the fence mounting screws
then retightening at different locations
along the table’s length.

Adjusting the fence angle

After mounting the Incra Fence to your

Ultra Lite, check the angle of the fence to
the router table using a machinist’s or
carpenter’s square. Sometimes, as a result
of the plywood not being perfectly flat, the
angle may be slightly more or less than 90°.
To correct the angle, place a masking tape
shim between the mounting bracket and the
fence as shown in Fig. 5.

Assemble stop positioner

Place a #8 flat washer on each of the

(2) #8-32 x

" thumb screws and insert

through two of the holes in the black plastic
stop positioner. Loosely install the (2) #8-32
hex nuts, then slide the nuts into the T-slot
on the front of the Incra Fence. Fig. 4.
When not in use, simply slide the stop
positioner off the fence.

If you wish to upgrade your Incra
Fence to add the ultra-precise stop
positioning abilities of the New Incra
Stop, see the fence upgrade
package offered on page 16.

MAINTENANCE

In general, just keeping your Incra Jig clean is all
you need to do to keep the tool in tip top shape.
Occasionally, remove the carriage from the base and
brush or blow out any sawdust or debris that may have

accumulated on the base and the UHMW guide
bearing strips. Use a toothbrush to clean the teeth
on the Incra racks on both the carriage clamp and
on the carriage.
