Using extension cords may reduce the life of the
motor. Instead, place the machine near a power
source. If you must use an extension cord:
• For 110V, use at least a 12 gauge cord that
does not exceed 50 feet in length.
• For 220V, use at least a 14 gauge cord that
does not exceed 50 feet in length.
• The extension cord must have a ground wire
and plug pin.
