It seems to only run on the high end of the RPM scale. I have manual and have no idea what the RPM reads on the dial, is it X 1000 ? it will not run but rather stalls at lower setting, below 3. Does anyone have a digital manual resource? Also and more importantly it makes a loud squealing noise when running at higher RPM which is intermittent, it comes and goes as it runs. Machine is clean and has no obvious damage from the outside. wires look clean and tidy inside, pulled bottom plate off to check for dust. The squealing to me sounds like a bearing is about to eat it. Any one have experience servicing these or replacing that loud bearing when it goes? Cheers,Reply
