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, 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.
