DeWalt 36-714 instruction manual Using AN Accessory Dado Head, Must

1.You can easily attach a moulding cutterhead (A) Fig. 59 to the saw arbor. Also, you must use the accessory moulding cutterhead table insert (B) in place of the standard table insert.

2.When using the moulding cutterhead, add wood-facing (C) to the face of the rip fence (Fig. 60). The wood-facing is attached to the fence with wood screws through holes which must be drilled in the fence. Stock that is 3/4" inch thick is suitable for most work, although an occasional job may require 1" facing.

3.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. 60 shows a typical moulding operation.

Never use a moulding cutterhead in a bevel position.

Never run the stock between the fence and the moulding cutterhead. Irregular-shaped wood will cause kickback.

Give special attention to the grain direction. Make all cuts in the same direction as the grain whenever possible.

Always install the blade guard after the operation is complete.

USING AN ACCESSORY DADO HEAD
							Fig. 61
		The blade guard and splitter assembly
	cannot be	used when dadoing or moulding. It must
	be removed as described in “USING AN ACCESSORY
	MOULDING CUTTERHEAD” section.
		Use pushsticks, hold-downs, jigs, fixtures,
	or featherboards to help guide and control the workpiece
	when the guard cannot be used.
		The accessory dado head set table insert (E)
	Fig. 64 must	be used in place of the standard table insert.
	Dadoing is cutting a rabbet or wide groove into the
	workpiece. 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 the teeth do not hit
	each other during rotation. The heavy portion of the cutters
	should fall in the gullets of the outside saws (Fig. 61). The
	saw and cutter overlap is shown in Fig. 62 - (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.
	Position the teeth of the saws so that the raker on one saw				A			B
	is beside the cutting teeth on the other saw.
		Do not attempt to stack dado blades thicker						C
	than 13/16” (20mm) Do not use dado blades larger than
	8” (200mm) in diameter.
	Attach the dado head set (D) Fig. 64 to the saw arbor.
				Fig. 62		Fig. 63
	NOTE: If the arbor nut does not fully engage the thread on

the arbor, remove the outside arbor flange and 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.

Never use the dado head in a bevel position.

Always install the blade guard and standard table insert after the operation is complete.

NOTE: Fig. 65 illustrates a typical dado operation.
