Provide auxiliary support for any workpiece
extending beyond the table top with a tendency to
sag and lift up off the table.
Have the blade extend about 1/8" above the top of
the workpiece. Exposing the blade above this point
can be hazardous.

9.5 Bevel and miter operations
Bevel cut – A bevel cut is a special type of
operation where the saw blade is tilted at an angle
less than 90 degrees to the table top (Figure 9-11).
Operations are performed in the same manner as
ripping or crosscutting, except the fence or miter
gauge should be used on the right-hand side of the
blade to provide added safety in avoiding a binding
action between blade and table top. When beveling
with the miter gauge, the workpiece must be held
firmly to prevent creeping.
Figure 9-11
Mitering – Crosscuts made at an angle to the edge
of the workpiece are called miters (Figure 9-12).
Set the miter gauge at the required angle, lock the
miter gauge, and make the cut the same as a
normal crosscut except the workpiece must be held
extra firmly to prevent creeping.
Note : When making compound miters (with blade
tilted) use the miter gauge in the right hand slot to
provide more hand clearance and safety.
Have the blade extend only 1/8" above the top of
the workpiece. Exposing the blade above this point
can be hazardous.
Figure 9-12
Dado cutting – Dadoing is cutting a wide groove
into a workpiece or cutting a rabbet along the edge
of a workpiece. A dado insert (optional accessory,
not provided) shown in Figure 9-13, is necessary
for this type of operation.
Do not use the standard table
insert for dadoing operations.
Figure 9-13
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 type blade
mounted on the saw arbor. By using various
combinations of 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,
riving knife, 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 cannot 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 operators’
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.
