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, 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.
