Hi there, I'm having an annoying resonance in my (1.5 year old) Harman P35i. Any suggestions of things I should inspect, bolts I should tighten, etc? I've made a video of the issue. As you can see, the resonant sound seems to be most pronounced when the feed auger is operating (1:00 - 1:14) but can be heard faintly even when the feed auger is not on. Any help is appreciated!
