I've only ever spent time in workshops that are at workshop sound levels so can't speak for the hum but I think that it would work the same as the emergency stop, if you press that does anything happen?
I've tried the emergency stop but nothing changes, the only switch/button that seems to do anything is if you hold the green button the tool lamp comes on
awesome, I havent really done that much with machines like that, but a mate had something similar with a reeves drive. was a right pain. I think he ended up gutting it and getting a vfd + new motor.
