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.
CAUTION
keep the cord away from the cutting area
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 4,000
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
greater distance. A line that can support one power tool may
be able to support two or three tools.
GROUNDING INSTRUCTIONS
1. All ground, cord-connected tools:
In the event of a malfunction or breakdown, grounding
provides a path of least resistance for electric current to
reduce the risk of electric shock. This tool is equipped with an
electric cord having an equipment-grounding conductor and
a grounding plug. The plug must be plugged into a matching
outlet that is properly installed and grounded in accordance
with all local codes and ordinance.
Do not modify the plug provided. If it will not fit the outlet,
have the proper outlet installed by a qualified electrician.
Improper connection of the equipment- grounding conductor
can result in a risk of electric shock. The conductor with
insulation having an outer surface that is green with or
without yellow stripes is the equipment of the electric cord
or plug is necessary, do not connect the equipment-grounding
conductor to a live terminal.

Check with a qualified electrician or service personnel if the
grounding instructions are not completely understood, or if in
doubt as to whether the tool is properly grounded.
Repair or replace a damaged or worm cord immediately.
This tool is intended for use on a circuit that has an outlet like
the one shown in Figure 1.1. It also has a grounding pin like
the one shown.
2. Grounded,
cord-connected tools
intended for use on a
supply circuit having a
nominal rating less
than 150V:
This tool is intended for
use on a circuit that has
12
an outlet that looks like
12
the one illustrated in
Sketch A in
Figure1.2.
The tool has a
grounding plug that looks like the plug illustrated in Sketch
A in Figure 1.2. A temporary adapter, which looks like the
adapter illustrated in Sketches B and C, may be used to
connect this plug to a 2-pole receptacle as shown in sketch B
if a properly grounded outlet is not available. The temporary
adapter should be used only until a properly grounded outlet
can be installed by a qualified electrician. The green-colored
rigid ear, lug, and the like, extending from the adapter must
be connected to a permanent ground such as a properly
grounded outlet box.
3. Grounded, cord-connected tools intended for use on a
supply circuit having a nominal rating between 150-250V,
inclusive:
This tool is intended for use on a circuit that has an outlet that
looks like the one illustrated in Sketch D in Figure 1.2. The
tool has a grounded plug that looks like the plug illustrated in
Sketch D in Figure 1.2. Make sure the tool is connected to an
outlet having the same configuration as the plug. No adapter
is available or should be used with this tool. If the tool must be
reconnected for used on a different type of electric circuit, the
reconnection should be made by qualified service personnel;
and after reconnection, the tool should comply with all local
codes and ordinances.
