Motor oil

Anyone have a user manual for the old Beckman tabletop ultra centrifuges (max and MaxE models) I have a circa 2000 model (130000 rmp model) and need to know the oil used in the main motor, and the oil used in the vacuum pump.

Also, would love to know if the nuts on the top motor cover that secure it to the bottom cover are really supporsed to be regular nuts? Seems like this would be a design flaw- lock nuts would make more sence. I can t be the only one that had these loosen and let the gasket leak?
