EXTENSION CORDS
The use of any extension cord will cause some loss of
power. To keep the loss to a minimum and to prevent
tool from overheating, use an extension cord that is
heavy enough to carry the current the tool will draw.
A wire gage size (A.W.G.) of at least 16 is recom-
mended for an extension cord 100 feet or less in
length. When working outdoors, use an extension
cord that is suitable for outdoor use. The cord's jacket
will be marked WA.
