Without a model number, it's going to be tough chasing down a manual. Where did you get the device in the first place? Try a Google search on "MCT/Browne" (in quotes). I'm guessing that the Browne Corp. (Santa Barbara, CA) is defunct. Sonic Manufacturing also makes reflow stations, so maybe they bought Browne? A popularly mentioned model is an LR-6 belt reflow station with a 4" belt. Does that look anything like what you've got?
