EXTENSION CORDS
Use only 3-wire extension cords that have 3-prong
grounding plugs and 3-pole receptacles that accept
the tool's plug. When using a power tool at a consider­
able distance from the power source, use an exten­
sion 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 jack­
eted cords listed by Undenwriter's Laboratories (UL)
should be used.
Length of Extension Cord Wire Size (A.W.Q.)
Up to 25 feet 14
26-100 feet 12
When working with the tool outdoors, use an exten­
sion 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.
CAUTION: Keep the cord away from the cutting
area and position the cord so that it wili not be
caught on lumber, tools, or other objects during
cutting operations.
ELECTRICAL CONNECTION
Your Sears Craftsman Radial Arm Saw 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), it should be connected
to a 240 volt power supply only If it has been reset
according to the instructions in this manual. The
motor has been set at the factory for 120 volts; if it is
reconnected to operate at 240 volts, the main power
cord plug and any receptacle must be replaced with
devices rated for 240 volts. This tool will not operate
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.
SPEED AND WIRING
The no-load speed of your saw is approximately 3,600
ipm. This speed is not constant. 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 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 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-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 senrice 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 immedi­
ately.
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.
