I just purchased the 2hp HF dust collector. Got it all together and working with out any issues. I fired it up about 4-5 times with out any problems. Then when I tried showing it off to my father it didn't want to start. It sounded like the capacitor was at fault because the motor just buzzed. I tried to spin the impeller over with a stick and while it was still rotating flick the switch but that didn't help. Has anyone else had a problem like that?
