I have 2 rough-running, four-point, orbital, oscillating buffers that need to run smooth again.
These are heavy duty, 2-handled, 2 Amp, 3240 rpm, four-point, orbital, oscillators that were converted to professional massagers. Both of them now run really rough and I can't keep buying new ones nor can I afford to ship them back to the company for refurbishing. I assume they only need lubrication, but I can't figure out how to open them up nor does there appear to be any one around here who repairs power tools. (Rock and a hard place, eh?) Can anyone help? I have a photo, although those two black knobs do not exist on my units.
