USE PROPER EXTENSION CORD. Make sure your
extension cord is in good condition. When using an
extension cord, be sure to use one heavy enough to
carry the current your product will draw. An
undersized cord will cause a drop in line voltage
resulting in loss of power and overheating. Table 1
shows the correct size to use depending on cord
length and nameplate ampere rating. If in doubt, use
the next heavier gage. The smaller the gage number,
the heavier the cord.
