We just acquired an RO-260E reflow oven for doing prototypes and very small production runs, we are currently having issues with the conveyor motor. Before we got the oven the persons that had it before did some modifications to the conveyor system and lost all the original parts. I called Essemtec for replacements but they no longer have any or a repair manual. Does anyone have a copy of the repair manual for this machine? any information on the original Conveyor motor that came stocked on the machine? I am looking for a part number (not essemtec PN) or a direct replacement we can purchase.
