EXTENSION CORDS
Use only 3-wire extension cords that have 3-prong ground-
ing plugs and 3-pole receptacles that accept the tool's plug,
When using a power tool at a considerable distance from the
power source, use an extension cord heavy enough to carry
the current that the tool will draw. An undersized extension
cord will cause a drop in line voltage, resulting in a loss of
power and cause the motor to overheat. Use the chart pro-
vided below to determine the minimum wire size required in
an extension cord. Only round jacketed cords listed by Under-
writers Laboratories (UL) should be used.

When working with the tool outdoors, use an extension cord
that is designed for outside use. This is indicated by the let-
ters WA on the cord's jacket.
Before using an extension cord, inspect it for loose or exposed
wires and cut or worn insulation.

GLOSSARY OF TERMS FOR WOODWORKING

Anti-Kickback Pawls: Toothed safety devices behind the
blade designed to stop a workpiece from being kicked back
at the operator during a ripping operation.
Arbor: The shaft on which a blade or cutting
tool is mounted.
Bevel Cut: A cutting operation made with the blade at any
angle other than 90°to the saw table.
Compound Cut: A cut with both a miter angle and a bevel
angle.
Crosscut: A cutting operation made across the grain or the
width of the workpiece.
Dado A non-through cut that gives a square notch or
though; requires a special blade.
Feather board: A device to help guide workpieces during
rip cuts.
Freehand (for Table Saw): Dangerous practice of making a
cut without using rip or miter fences. See Safety Rules.
Gum: A sticky, sap-based residue from wood products.
Heel: Alignment of the blade.
Kerf: The material removed by the blade in a through cut or
the slot produced by the blade in a non-through cut.
Kickback: A hazard that can occur when blade binds or
stalls, throwing workpiece back toward operator.
Leading End: The end of the workpiece pushed into the cut-
ting tool first.
Miter Cut: A cutting operation made with the miter gage at
any angle other than 0°.

CAUTION
and position the cord so that it will not be caught on
lumber, tools, or other objects during cutting operations.
ELECTRICAL CONNECTION
Your Table Saw is powered by a precision built electric motor.
Do not operate this tool on direct current(DC). A substantial
voltage drop will cause a loss of power and the motor will
overheat. If the saw does not operation when plugged into an
outlet, double check the power supply.
SPEED AND WIRING
The no-load speed of your table saw is approximately 3600
rpm. This speed is not constant and decreases under a load
or with lower voltage. For voltage, the wiring in a shop is as
important as the motor's horse-power rating. A line intended
only for lights cannot properly carry a power tool motor. Wire
that is heavy enough for a short distance will be too light for a
12
greater distance. A line that can support one power tool may
12
be able to support two or three tools.
GROUNDING INSTRUCTIONS
This tool should be connected to a grounded metal permanent
wiring system; or to a system having an equipment-grounding
conductor.
Molding: A non-through cut that gives a varied shape to the
workpiece and requires a special blade.
Push Stick: A device used to feed the workpiece through
the saw blade during narrow cutting operations. It helps
keep the operator's hands well away from the blade.
Rabbet: A notch in the edge of a workpiece.
Re saw: A cutting operation to reduce the thickness of the
workpiece in order to make thinner pieces.
Resin: A sticky, sap-based substance.
Rip Cut: A cut made with the grain of the workpiece.
Saw blade Path: The area directly in line with
the blade –over, under, behind, or in front of it. Also, the
workpiece area which will be or has been cut by the blade.
Set: The distance that the tip of the saw blade tooth is bent
(or set ) outward from the face of the blade.
Throw-Back: Saw throwing back a workpiece; similar to
kickback.
Through Sawing: Any cutting operation where the blade
extends completely through the workpiece.
Trailing End: The workpiece end last cut by the blade in a
rip cut.
Workpiece: The item on which the cutting operation is being
done. The surfaces of a workpiece are commonly referred to
as faces, ends, and edges.
Worktable: The surface on which the workpiece rests while
performing a cutting operation.
