III. Electrical information (continued)
CAUTION: 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. B 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.
