Hobart C-10 info please

I just picked up a C-10. I have not seen any videos for how to disassemble or anything at all related to a Hobart C-10. Given its age, I would like to understand and learn how to properly relubricate the gears and or motor, but don't have a clue about how to.

I have read several posts by Nanapoopoola, Turteldude1 and Rhulsman who all have C-10s. Can any of you or others who have torn one of these down provide guidance on how to regrease this unit?
