ANTI-KICKBACK PAWLS: Spring-loaded "fin-
gers" that engage the work piece as it is being
fed through the saw. They restrict movement of
the work piece back in the direction of the oper-
ator.
ARBOR: The shaft on which a cutting tool is
mounted.
BARRIER GUARD: An assembly that consists
of the mounting fork and two side barriers. This
assembly is intended to provide a physical bar-
rier between the operator and the spinning saw
blade.
BEVEL: Blade angle relative to the table surface.
CROSSCUT: A cutting or shaping operation made
across the width of the workpiece cutting the work-
piece to length.
DADO: A non-through cut which produces a
square sided notch or trough in the workpiece.
FEATHERBOARD: A device which can help
guide workpieces during rip type operation by
keeping workpiece in contact with the rip fence. It
also helps prevent kickback.
FREEHAND: Performing a cut without a fence,
miter gauge, fixture, hold down or other proper de-
vice to keep the workpiece from twisting during the
cut and can be a safety hazard.
GUM: A sticky, sap-based residue from wood
products. After it has hardened, it is referred to as
"RESIN".
HEEL: Misalignment of the blade which causes
the trailing or out feed side of the blade to contact
the cut surface of the work piece. Heel can cause
kickback, binding, excessive force, burning of the
workpiece or splintering. In general, heel cre ates
a poor quality cut and can be a safety hazard.
KERF: The space in the workpiece where the ma-
terial was removed by the blade.
KICKBACK: An uncontrolled grabbing and throw-
ing of the workpiece back toward the front of the
saw during a rip type operation.
LEADING END: The end of the workpiece which,
during a rip type operation, is pushed into the cut-
ting tool first.

Glossary of Terms

MOLDING: A non-through cut which produces a
special shape in the workpiece used for joining or
decoration.
NON THROUGH SAWING: Any cutting operation
where the blade does not extend through the
workpiece (e.g. Dado, Rabbet).
PARALLEL: Position of the rip fence equal in dis-
tance at every point to the side face of the saw
blade.
PERPENDICULAR: 90° (right angle) intersection
or position of the vertical and horizontal planes such
as the position of the saw blade (vertical) to the
table surface (horizontal).
PUSH BLOCK: A device used for ripping-type op-
erations too narrow to allow use of a Push Stick.
Use a Push Block for rip widths less than 2 inches.
PUSH STICK: A device used to feed the work-
piece through the saw during narrow ripping-type
operation and helps keep the operator's hands
well away from the blade. Use the Push Stick for
rip widths less than 6 inches and more than 2
inches.
RABBET: A notch in the edge of a workpiece. Also
called an edge dado.
REVOLUTIONS PER MINUTE (R.P.M.): The
number of turns completed by a spinning object in
one minute.
RIPPING: A cutting operation along the length of
the workpiece cutting the workpiece to width.
RIVING KNIFE OR SPREADER: A device that
keeps the kerf of the work piece open as the
material is cut. This minimizes the potential of
the work piece binding against the saw blade.
SMART GUARD: A system made up of 3 com-
ponents: Riving Knife / Splitter, Anti-Kickback
Pawls, and Main Barrier Guard.
THROUGH SAWING: Any cutting operation
where the blade extends through the workpiece.
WORKPIECE: The item on which the cutting op-
eration is being performed. The surfaces of a
workpiece are commonly referred to as faces,
ends and edges.
