Serious injury could occur if you connect the machine to power before completing the setup process. DO NOT connect to power until instructed later in this manual.
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 gets 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 require- ments:
Minimum Gauge Size | 10 AWG |
Maximum Length (Shorter is Better) | 50 ft. |
