All three speeds do work but I do not know if it got up to full speed. There was no "shaking" or "rattling" when it was on. It is the "open" model design with two areas that are supposed to be oiled every three months - its a good guess that it has not been oiled in decades. Please see the pictures for condition as they are part of the description.
