EXTENSION CORDS
Use proper extension cords. Make sure
your extension cord is in good condition and is a 3-wire
extension cord which has a 3-prong grounding type plug
and matching receptacle which will accept the
machine’s plug. When using an extension cord, be sure
to use one heavy enough to carry the current of the
machine. An undersized cord will cause a drop in line
voltage, resulting in loss of power and overheating. Fig.
D-1 or D-2, shows the correct gauge to use depending
on the cord length. If in doubt, use the next heavier
gauge. The smaller the gauge number, the heavier the
cord.
