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 throat plate

(L) Fig. 65 must be used in place of the standard throat

plate. Be sure the throat plate is level to the table before

you proceed.

Always check dado blade clearance before

plugging in the saw.

To reduce the risk of injury,

be sure to

place the blade guard assembly and standard throat

plate back in position and check adjustments when

the dado cuts are complete. Reinstall blade guard

assembly, anti-kickback assembly and riving knife.

Never use the dado head in a bevel

position.

Dadoing is cutting a rabbet or wide groove into the

workpiece, as shown in Fig. 66. Most dado head sets

are made up of two outside blades and four or five inside

chippers, (Fig. 67). Various combinations of blades and

chippers are used to cut grooves from 1/8" (3.2 mm) to

1" (25.4 mm) for use in shelving, making joints, tenoning,

grooving, etc.

NOTE: The standard outer arbor flange nut assembly (M)

Fig. 65 cannot be used with dado blade sets. A special

nut (N) is included with the Unisaw to be used in dado

applications. Tighten this arbor nut against the dado

blade set. Do not discard the outer arbor flange nut. It

will be needed when reattaching the standard blade

to the arbor.

To arrange a typical dado set:

1. The blades and chippers (DELTA 35-7670 is used

in this example) are heavily swaged and must be

arranged so that the teeth do not hit each other

during rotation. The heavy portion of the chippers

should fall in the gullets of the outside blades

(Fig. 68).

2. The blade and chipper profile is shown in Fig. 69.

Washers, if needed for fine width adjustment, can be

placed anywhere between the outside blades and the

chippers. A 1/4" (6.4 mm) groove is cut by using the

two outside saws alone.

3. Position the teeth of the blade/chipper so that the

raker on one is beside the cutting teeth on the other.

4. Attach the dado head set to the saw arbor using the

arbor nut (N) Fig. 65.

NOTE: If a deep cut is required. Use several successive

passes rather than attempting to make it with one pass.

Maximum dado width on this saw is 1" (25.4 mm). DO

NOT USE WIDER COMBINATIONS.

To reduce the risk of injury, always return

and fasten the riving knife and blade guard assemblies

to the proper operating position for normal through

sawing operations. Also, be sure the standard throat

plate is back in position.
