Common household current is 110-120 volts. As long as your tool is rated from 110V-120V there
will be no complications using this tool with household receptacles. If your tool is rated 220V-240V
it has a completely different style of plug and must be used with a 220V-240V receptacle. Never try
to plug a 110V-120V tool into a 220V-240V circuit (or vice-versa) or serious complications will
arise, including possible injury to the operator. The plugs and receptacle have completely different
shapes to prevent this from occurring accidentally. Do not modify your plug in any way. If you have
any doubts, call a qualified electrician.
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). If you are using the
tool outdoors, you must use an extension cord rated for outdoor use. This is signified by the letters
“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 signified by its AWG (American Wire Gauge) rating.
The smaller the gauge, the greater the cable’s capacity. It does not matter if you are using one
cord, or two or more- the total length is what is used to determine the minimum AWG rating. Every
cord used 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.
Always inspect extension cords for any damage. If there are any loose, frayed, or exposed wires;
damaged insulation; or defective connections, the cord must not be used. Harbor Freight Tools
can supply UL listed and outdoor rated cords in multiple AWG rating if needed.
