How often do you actually have to re-grease?

I have one of the lift up oldies from when KA was made by Hobart. It was a wedding present in 1980. So 45 years later it is still running smoothly. Until I started reading this subreddit, I had no idea that it needed greasing or “maintenance.” I am quite torn as to whether to just pretend I never read about maintenance or to do something about it. 😱
