USING AN ACCESSORY DADO HEAD

To reduce the risk of injury, turn unit off

and disconnect it from power source before installing

and removing accessories, before adjusting or when

making repairs. An accidental start-up can cause injury.

Do not attempt to stack dado blades

thicker than 13/16" (20 mm) Do not use dado blades

larger than 8" (200 mm) in diameter.

The splitter and blade guard assemblies

cannot be used when dadoing or molding. It must be

removed as described in Blade Guard and Splitter Use

section. Use EXTREME care when using the dado

without the blade guard assembly and splitter.

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

(E) Fig. 64 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 splitter.

Never use the dado head in a bevel position.

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" (3.18 mm)

to 13/16" (20.64 mm) 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. 62). The saw and cutter overlap is shown in Fig. 63 - (A) being the outside saw, (B) an inside cutter, and

or washers, used as needed to control the exact width of groove. A 1/4" (6,35 mm) groove is cut by

using the two outside saws. Position the teeth of the saws so that the raker on one saw is beside the cutting teeth on

the other saw.

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

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.

NOTE: Fig. 65 illustrates a typical dado operation.

To reduce the risk of injury, always return and fasten the splitter 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.
