gRounDing / VoLTagE WaRning

Common household current is 110-120 volts.  As long as the outlet used with this 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 30-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.

This tool has a three-prong plug.  The third (round) prong is the ground.  Cutting off the ground will 

result in a safety hazard and void the warranty.
If the outlet you are planning to use is the two-prong type, do not remove or alter the grounding 

prong in any manner.  Use an adapter and always connect the grounding lug to a known grounding 

source.  It is recommended that you have a qualified electrician replace the two-prong outlet with a 

properly grounded three- prong outlet.

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
