EXTENSION CORDSU S E PROPER EXTENSION CORD. Make sureyour extension cord is in good condition.When using an extension cord, be sure to useone heavy enough to carry the current yourproduct will draw.An undersized cord willcause adrop in line voltage resulting in lossof power and overheating.Table 1shows thecorrect size to use depending on cord lengthand nameplateampere rating. If in doubt, usethe next heavier gage.The smaller the gagenumber, the heavier the cord.
