when i disassembled a c-man RAS from the 60s, i found an impressive amount of grease in the gears that connected the elevation rod (with the crank handle) to the rod within the column that supports the overhead track. i don't think that's an area you need to be concerned with, especially as i seem to recall literally having to take most of the column support apart to get to it.
as far as the roller dearings that hold the saw carriage to the overarm tracks, a little white lithium grease or dry lube should do the trick. if using WLG, just make sure it's completely dry before conducting any operations that would introduce sawdust to the WLG. otherwise, it tends to attract and hold sawdust, resulting in a gummy mess.
i presently have a mid 60s c-man RAS in the shop and find that it requires very little lubrication or adjustment, but it's use is restricted to 90° crosscuts.
there's a solution to every problem.....you just have to be willing to find it.
