Grounding/Voltage Warning
Common household current is 110-120 volts. As long as the outlet used with the tool is rated from 110-120V
there will be no complications using it with household receptacles. Plug the tool into a 110-120v properly
grounded outlet protected by a 15-amp, dual element time delay or circuit breaker.
NEVER try to plug a 110-120V tool into a 220-240V circuit or serious complications and possible injury to the
operator may occur. The plugs have different shapes to prevent this.
Extension Cords
Your tool has a three-prong plug, therefore you must use a three-prong extension cord. Only use rounded jacket
extension cords listed by the Underwriters Laboratories (UL). Improper use of extension cords may cause
inefficient operation of your tool which can result in overheating. Be sure your extension cord is rated to allow
sufficient current flow to the motor.
If you are using the tool outdoors, use an extension cord rated for outdoor use (signified by “WA” on the jacket).
The extension cord must have a minimum wire size depending on the amperage of the tool and the length of the
extension cord. This size is determined by its AWG (American Wire Gauge) rating. The smaller the gauge, the
greater the cable’s capacity. The amount of cords used does not matter: Total length determines the minimum
AWG rating. Every cord must meet the AWG rating. Use the chart below to determine what AWG rating is required
for your situation. Cord length is rated in feet. Harbor Freight Tools can supply UL listed and outdoor rated
cords in multiple AWG ratings if needed.
