IMPORTANT: For certain cutting operations such as
dadoing and moulding where you are not cutting
completely through the workpiece, the blade guard and
splitter assembly cannot be used. Simply loosen screws
(G) and (H) Fig. 139. Lift up and swing blade guard and
splitter assembly (W) Fig. 140, to the rear of the saw as
shown in Fig. 140. CAUTION: Always return and fasten
the blade guard and splitter assembly to its proper
operating position for normal thru-sawing operations.
The moulding cutterhead (A) Fig. 141, is assembled to the
saw arbor as shown. Also, the accessory moulding
cutterhead table insert (B), must be used in place of the
standard table insert.
It is necessary when using the moulding cutterhead to
add wood-facing (C) to the face of the rip fence, as
shown in Fig. 142. The wood-facing is attached to the
fence with two clamps, as shown. 3/4 inch stock is
suitable for most work although an occasional job may
require 1 inch facing.
Position the wood-facing over the cutterhead with the
cutterhead below the surface of the table. Turn the saw
on and raise the cutterhead. The cutterhead will cut its
own groove in the wood-facing. Fig. 142, shows a typical
moulding operation. NEVER USE MOULDING CUTTER-
HEAD IN A BEVEL POSITION.
IMPORTANT: NEVER RUN THE STOCK BETWEEN THE
FENCE AND THE MOULDING CUTTERHEAD AS IRRE-
GULAR SHAPED WOOD WILL CAUSE KICKBACK.
When moulding end grain, the miter gage is used. The
feed should be slowed up at the end of the cut to prevent
splintering.
In all cuts, attention should be given the grain, making the
cut in the same direction as the grain whenever possible.
ALWAYS INSTALL BLADE GUARD AFTER
OPERATION IS COMPETE.

USING ACCESSORY
DADO HEAD
IMPORTANT: THE BLADE GUARD AND SPLITTER
ASSEMBLY CANNOT BE USED WHEN DADOING OR
MOULDING AND MUST BE REMOVED OR SWUNG
TO THE REAR OF THE SAW.
Dadoing is cutting a rabbet or wide groove into the work.
Most dado head sets are made up of two outside saws
and four or five inside cutters, as shown in Fig. 143.
Various combinations of saws and cutters are used to cut
grooves from 1/8" to 13/16" for use in shelving, making
joints, tenoning, grooving, etc. The cutters are heavily
swaged and must be arranged so that this heavy portion
falls in the gullets of the outside saws, as shown in Fig.
144. The saw and cutter overlap is shown in Fig. 145, (A)
being the outside saw, (B) an inside cutter, and (C) a
paper washer or washers which can be used as needed
to control the exact width of groove. A 1/4" groove is cut
by using the two outside saws. The teeth of the saws
should be positioned so that the raker on one saw is
beside the cutting teeth on the other saw.
