ELECTRICAL
SPEED AND WIRING
The no-load speed of this tool is approximately 1,75
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 horsepower 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 not be able to support two
or three tools.
GROUNDING INSTRUCTIONS
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 ordinances.
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 con-
ductor can result in a risk of electric shock. The conduc-
tor with insulation having an outer surface that is green
with or without yellow stripes is the equipment-grounding
conductor. If repair or replacement 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 worn cord immediately.
This tool is intended for use on a circuit that has an outlet
like the one shown in figure 1. It also has a grounding pin
like the one shown.
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 causing the motor to overheat. Use the chart
provided below to determine the minimum wire size required
in an extension cord. Only round jacketed cords listed by
Underwriter's Laboratories (UL) should be used.

NOTE: AWG = American Wire Gauge
When working with the tool outdoors, use an extension cord
that is designed for outside use. This is indicated by the
letters “WA” on the cord's jacket.
Before using an extension cord, inspect it for loose or
exposed wires and cut or worn insulation.
WARNING:
Keep the extension cord clear of the working area.
Position the cord so that it will not get caught on
lumber, tools or other obstructions while you are
working with a power tool. Failure to do so can
result in serious personal injury.
WARNING:
Check extension cords before each use. If dam-
aged replace immediately. Never use tool with a
damaged cord since touching the damaged area
could cause electrical shock resulting in serious
injury.
ELECTRICAL CONNECTION
This tool is powered by a precision built electric motor. It
should be connected to a
power supply that is 120 volts,
60 Hz, AC only (normal household current). 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 operate when plugged into an outlet, double
check the power supply.
