AP92 focuser question

Yes, first tighten these two screws and see if that corrects the issue. There are also 4 tiny set screws, one in each corner. They are used to set the distance of the pinion from the rack. The third setscrew which is in the middle toward the lower end in your picture - don't adjust it.

Just noticed that if I loosen the focuser lock screw then the entire pinion assembly wobbles up and down. If the focuser is fully locked then it does not wobble (or only a little).
Shall I tighten highlighted 2 screws to fix this issue?
