The blade guard and splitter assembly cannot be used when dadoing or moulding. It must be removed or swung to the rear of the saw as described in “USING ACCESSORY MOULDING CUTTERHEAD” SECTION.

Auxiliary jigs, fixtures, push sticks and feather boards should be used.

1.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, (Fig. 61). 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. 62. The saw and cutter overlap is shown in Fig. 63, (A) being the outside saw, (B) an inside cutter, and (C) a paper washer or washers, 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.

2.Attach the dado head set (D) Fig. 64, to the saw arbor.

NOTE: The outside arbor flange cannot be used with the dado head set. Tighten the arbor nut against the dado head set body. Do not lose the outside arbor flange. It will be needed when reattaching a blade to the arbor.

The accessory dado head set table insert (E) FIG. 64, must be used in place of the standard table insert.

The blade guard and splitter assembly cannot be used when dadoing and must be removed or swung to the rear of the saw as explained previously in this manual. Auxiliary jigs, fixtures, push sticks and feather boards should also be used.

3.Fig. 65 shows a typical dado operation using the miter gauge as a guide.

Never use the dado head in a bevel position.

Always install the blade guard after the operation is completed.
