nope this is on the same level as the lens here is a picture circled in red it spins with the machine while its running.

It's an inching knob.

If you spin it clockwise it will advance the film frame by frame, anticlockwise it will go back a frame.

One complete revolution = 1 frame advance.

Motor off, needless to say!

Bart beat me to it. The inching knob is used to manually advance the film, which is always good for syncing those Americom films where you need to start with the "dot" frame in the gate. Also good for retracting the pull down claw while cleaning.

IIRC there are some Eumigs (the ones where you swap the Super/Standard 8 gate??) where the inching knob is marked with a red dot that you have to align correctly if you want to swap them over so that you don't snap off the claw teeth. In the red dot position the teeth are drawn back into the projector.

That is true, and as much as I like the Eumig 800 series this is my major gripe with them: the chance to reduce a perfectly good machine to a boat anchor by making just one mistake!
