The distance the fence is positioned away from the
blade is indicated by the two witness lines (B) and (C) Fig.
72, located on the cursor (D). The witness lines (B) and (C)
indicate the distance the fence is positioned away from
the saw blade. Witness line (B) indicates the distance the
fence is away from the blade when the fence is in the
horizontal position, and witness line (C) indicates the
distance the fence is away from the blade when the fence
is in the vertical position. If it is necessary to adjust cursor
(D), make a test cut with the fence in either the vertical or
horizontal position, measure the distance of the finished
cut and move the cursor (D) by loosening the two screws
(E) Fig. 72. After adjustment is completed tighten the two
screws (E).

To remove the fence and fence body assembly (F)
Fig. 73, from the guide rail, lift up on fence clamping lever
(A) and turn lever (A) to the left indent position. The fence
assembly (F) can then be pulled straight off the guide rail
and removed.

RIPPING WITH THE
UNIFENCE
Ripping is the operation of making a lengthwise cut
through a board, as shown in Fig. 74, and the rip fence
(A) is used to position and guide the work. One edge of
the work rides against the rip fence while the flat side of
the board rests on the table. Since the work is pushed
along the fence, it must have a straight edge and make
solid contact with the table. The saw blade guard must
be used. The guard has anti-kickback fingers to prevent
wood kickback, and a splitter to prevent the wood kerf
from closing and binding the blade.
Never stand in the line of the saw cut when ripping. Hold
the work with both hands and push it along the fence and
into the saw blade as shown in Fig. 74. The work can then
be fed through the saw blade with one or two hands. After
the work is beyond the saw blade and anti-kickback
fingers, the hand is removed from the work. When this is
done the work will either stay on the table, tilt up slightly
and be caught by the end of the rear guard or slide off the
table to the floor. Alternately, the feed can continue to the
end of the table, after which the work is lifted and brought
along the outside edge of the fence. The cut-off stock
remains on the table and is not touched with the hands
until the saw blade is stopped, unless it is a large piece
allowing safe removal. When ripping boards longer than
three feet, it is recommended that a work support be used
at the rear of the saw to keep the workpiece from falling off
the saw table.
If the ripped work is less than 4 inches wide, a push stick
should always be used to complete the feed, as shown
in Fig. 75, (see the section on “Constructing a Push
stick”).
When ripping material under 2 inches in width, a flat
pushboard is a valuable accessory since ordinary type
