> I got a used MA-550 tower, first owner bought it in 2007.
the cables to rise up and down and to lay it are very dry and a bit oxidize
in some places, also the pulleys.
> May I put a mechanical oil or fat on it or is not necessary?
No - do not use either of those. What you want is a thin kind of
lubricant so that it wicks into the strands. If you use anything else,
either the coating attracts contaminants or traps water inside the strands -
both of which are bad for the cables.
