A good start would be to get a copy of the manual from Clausing:

http://www.clausing-industrial.com/service-std.htm

AIR, they originially specified SAE 20 oil for pretty much everything, but
Vactra #2 way oil would probably be a nbetter lube to use in most places.

Are there any special problems or does it just need a clean up and lube?

Hello,

I recently inherited an old milling machine (Clausing 8520 Milling
Machine) and am looking for information regarding getting it up and
running-proper lubrication (especially motor and spindle bearings).
Does anyone have any tips (or warnings)on refurbishing/ lubrication of
this old machine?

Thanks,
Dave
