Do you know what broke exactly?

Nope, I just engaged the power down and it wasn't there any more. Means
you
got to stand there and push down by hand - sux on a deep large hole.

This makes me hope that it is something simple, some intentional weak
link. Maybe there is some roll pin that is purposely made to break
under excess load.

Very likely, being able to talk to somebody that knows this machine or
having an assembly drawing would be worth its weight in gold.
