Leveling the Fixed Leg Table

I’ve been unable to find a manual or instruction video (other than the announcement video) for the QWC Woodworker Fixed Leg Table. Using the rolling table instructions I was able to figure out how to build it, but I’m struggling with the leveling feet which are significantly different from any style I’ve see before.

Has anyone had any experience with leveling the fixed leg stand that they could share with me or send me a reference to an instruction manual or video that is relevant to the fixed leg stand?

Many thanks!
