EXTENSION CORDS
Never use a damaged extension cord. Check extension cords before each use. If damaged, replace immediately.
Touching the damaged area could case electrical shock resulting in serious injury.
Keep the extension cord clear of the work area. Position the cord so it will not get caught on lumber, tools or
other obstructions.
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 below shows the maximum 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. Only round, jacketed
cords listed by Underwriter's Laboratories (UL) should be used.
