14 gauge copper is 2.58 ohms per 1000'. For a 10' cord, that's a .45 volt drop at 8.8 amps. At 8.8 amps that's about a 4 watt loss. No big deal in my opinion. However I would check for any hot spots on the plug, cable, and motor connections to be sure. Go for it. I know, someone is going to kick in about local building codes etc.
