Brass trimmer problem.

[gunpoorboy1]

I just got a RCBS Trim Pro-2 case trimmer. In setting it up I'm having this problem.

The "Fine" and "Course" adjustment knobs each have a set screw to tighten and loosen for adjusting the depth of the cut. I'm going on the instructions and on line videos which show that they each turn and operate separately. I can loosen the set screw on the "Course" adjustment Bushing" and it will rotate as it should on the cutter shaft but when I loosen the set screw on the "Fine" adjustment bushing, it will not rotate on the shaft. It's as if it's locked into place. It will not turn even when I take the set screw completely out.

Am I doing this wrong?

Call RCBS. They will figure it out.
