Glossary Of Terms - skilsaw SPT99 Consignes D'utilisation/De Sécurité

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 sur-
face.
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 work-
piece.
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.
