Extension Cords
We do not recommend using an extension cord with this machine. If you must use an extension cord, only use it if absolutely necessary and only on a temporary basis.
Extension cords cause voltage drop, which may damage electrical components and shorten motor life. Voltage drop increases as the extension cord size gets longer and the gauge size get smaller (higher gauge numbers indicate smaller sizes).
Any extension cord used with this machine must contain a ground wire, match the required plug and receptacle, and meet the following requirements:
Minimum Gauge Size | 12 AWG |
Maximum Length (Shorter is Better) | 50 ft. |
