I just aligned everything as pictured using a side view as shown.The blade depth is also adjustable. Doesn’t state anything about that depth.
Why did they make any of it adjustable anyway?
Top of the tip should be flush with bottom of the blades - and centered side-to-side based on the top edge of the tip.
I suspect perfect alignment isn't critical since these chew they're way through instead of shave.
I made sure the two blades were on the same plane (using a straight edge before installing the point) - then installed the point.
