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. The table 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.
