I recently acquired a Bendix Model D ironer/mangle in great shape but without the owners manual, When it was moved it was tipped on it’s back rather than kept upright. Old oil leaked out of it. I cleaned it up but now I want to know how to change or replace the oil before I start to use it. I am not having any luck finding a manual or service information. Does anyone know how to change the oil or service this wonderful vintage machine. I found a manual for the IR brand but I don’t believe this will tell me what I need to know for my machine.
