Make sure your extension cord is in good condition.
When using an extension cord, be sure to use one
heavy enough to carry the current your product will
draw. A wire gauge size (A.W.G.) of at least 14 is
recommended for an extension cord 50 feet or less in
length. A cord exceeding 100 feet is not recommended.
If in doubt, use the next heavier gauge. The smaller
the gauge number, the heavier the cord. An undersized
cord will cause a drop in line voltage resulting in loss of
power and overheating.
