FUNCTIONAL DESCRIPTION
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. 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.
