RULES FOR SAFE OPERATION
• To reduce the risk of electrical shock, this unit has a
polarized plug (one blade is wider than the other) and
will require the use of a polarized extension cord. This
unit plug will fit into a polarized extension cord only
one way. If the plug does not fit fully into the extension
cord, reverse the plug. If the plug still does not fit,
obtain a correct polarized extension cord. A polarized
extension cord will require the use of a polarized wall
outlet. This plug will fit into a polarized wall outlet only
one way. If the plug does not fit fully into the wall
outlet, reverse the plug. If the plug still does not fit,
contact a qualified electrician to install the proper wall
outlet. Do not change the unit plug, extension cord
receptacle, or extension cord plug in any way.
• Ground Fault Circuit Interrupter (GFCI) protection
should be provided on the circuit(s) or outlet(s) to be
used for this unit. Receptacles are available having
built-in GFCI protection and may be used for this
measure of safety.
• EXTENSION CORDS: Make sure your extension cord
is in good condition. When using an extension cord,
be sure to use a cord that is heavy enough to carry the
current that your unit will draw. An undersized
extension cord will cause a drop in line voltage
resulting in loss of power and overheating. The table
shows the correct size to use depending on the cord
length and nameplate amperage rating. If in doubt, use
the next heavier size line gauge. The smaller the gauge
number, the heavier the cord. To reduce the possibility
of disconnection of the unit from the extension cord
during operation, see Fig. 5, page 7.
• A nameplate on your unit indicates what voltage it
uses. Never connect the unit to an AC voltage that
differs from this voltage.
