NOTE: When making compound miters

(with blade tilted) use the miter gauge in the

right hand slot to provide more hand

clearance and safety.

3. Have the blade extend only 1/8" above the

top of the workpiece. Exposing the blade

above this point can be hazardous.

Dado Cutting

Dadoing is cutting a wide groove into a

workpiece or cutting a rabbet along the edge of

a workpiece. A dado insert, shown in Figure 36,

is necessary for this type of operation.

Do not use the standard

table insert for dadoing operations.

The process of cutting 1/8" to 13/16" grooves in

workpieces is accomplished by the use of a

stacked dado blade set or an adjustable blade

mounted on the saw arbor.

By using various combinations of the stacked

dado blades, or properly setting the dial on an

adjustable blade, an accurate width dado can be

made. This is very useful for shelving, making

joints, tenoning, etc.

The guard, splitter, and anti-kickback pawls

supplied with the saw should be used for all

cutting operations where they can be used.

When performing operations where the guard

can not be used, as in some dadoing

operations, alternative safety precautions should

be taken. These include push sticks, feather

boards, filler pieces, fixtures, jigs and any other

appropriate device that can be utilized to keep

operator's hands away from the blade.

Upon completion of the operation requiring

removal of the guard, the entire guard assembly

must be placed back on the machine in its

proper working order.

Never use a dado head in a

tilted position. Never operate the saw

without the guard, splitter and anti-kickback

pawls for operations where they can be

used.

Safety Devices

Feather Board (Figure 37).

The feather board should be made of straight

grain hardwood approximately 1" thick and 4" to

8" wide depending on the size of the machine.

The length is developed in accordance with

intended use.

Feather boards can be fastened to the table or

rip fence by use of C-clamps.
