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. C, 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.
