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 operator .
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 workpiece to length .
DADO: A non-through cut that produces a
square-sided notch or trough in the workpiece .
FEATHERBOARD: A device that can help
guide workpieces during rip type operation by
keeping the 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
device 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 that 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
material was removed by the blade .
KICKBACK: An uncontrolled grabbing and
throwing of the workpiece back toward the front
of the saw during a ripping-type operation .
LEADING END: The end of the workpiece
which, during a ripping-type operation, is pushed
into the cutting tool first.

Glossary of Terms

MOLDING: A non-through cut which produces
a special shape in the workpiece; used for join-
ing or decoration .
NON THROUGH SAWING: Any cutting opera-
tion where the blade does not extend through
the workpiece (e .g . Dado, Rabbet) .
PARALLEL: Position of the rip fence equal in
distance at every point to the side face of the
saw blade .
PERPENDICULAR: 90° (right angle) intersec-
tion 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
operations that is 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 rip-
ping-type operations that 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
operation is being performed . The surfaces of
a workpiece are commonly referred to as
faces, ends and edges .
