Got it! You wind the nurled knob right in and the handwheel engages. Wind it out and waggle the level, the handwheel disengages.
Keep looking around it as there is a good chance it has power downfeed to the quill (used with a boring head rather than for poking a 1" drill through something). Sometimes they combine that with a settable trip mechanism to auto-disengage the feed.
The part that looks like a grinder nut, with four holes in holding the handwheel on looks more complicated than necessary for this simple function. Does it move in and out?
