Olympus service

I need to find information on how to lubricate an Olympus trinocular BH2 BHS
microscope. The trinocular head needs lubricating and I don't know what type
of lubricant to use or exactly how to. I might also need to lubricate the
parts that move the stage up and down. Where can I get a manual on Olympus
BH2 microscope service? I need to do the basic maintenance.
