Installing the Front Rail
1. Identify the front rail, which is 3" x 3" with
notches on one side.
2. Align the holes on the notched side of the
front rail to the holes in the front edge of the
table saw top, as shown in Figure 1. The
notches should fall below the miter slots in
the table.
Note: The rail's second hole from the left
should line up with the first hole in the table
top as shown. The saw's extension wings
are not pre-drilled at the factory, so use of
the first hole on the rail is optional.
3. Lightly secure the front rail to the saw table
with four 1/4-20 x 1-1/2 flat head screws,
four 1/4 flat washers, four 1/4 lock washers,
and four 1/4 hex nuts (Figure 2). Finger-
tighten only.
The front rail must be parallel to the table top in
order for the Accu-Fence system to function
properly.
1. Place an adjustable square on the table as
shown in Figure 3.
2. Check the height of the front rail at several
locations along the surface of the saw table.
The measurements should be the same
along the length of the rail. (Generally, this
dimension will be about 2-27/32”.)
3. When the front rail has been correctly
positioned, tighten all mounting screws
securely with a screwdriver and 10mm
wrench.
Installing the Back Rail
1. Locate the back rail which is 2" x 2" with
holes running along one side only. The back
rail should be installed parallel to the table
top.
2. Align the holes in the back rail to the holes in
the table top, as shown in Figure 4.
Note: The rail's second hole from the right
should line up with the first hole in the table
top as shown. The saw's extension wings
are not pre-drilled at the factory, so use of
the first hole on the rail is optional.
