Just a thought....

Are there others who think that seem to think that their 0766 got smoother over time?
Good point Brice. Things, especially machinery alwys have a bit of a break in period. Cold winter weather could make the belt stiff as well, and cause some resonance. I know that my 0766 is smoother & quieter than when I uncrated it. I’m very happy with mine. I also went through my machine and tightened everything that could be tightened up before powering up the first time.
