I just bought a new router (DeWalt 618, changeable fixed/plunge base). It comes with the motor mounted on the fixed base, which is what I planned to use anyway. I opened the locking lever and tried to turn the dial to adjust the depth, but nothing budged. The instructions were no help: in fact, they just added to the puzzle. In this diagram from the manual, the depth adjustment ring is part of the fixed base:
However, in this photo, you can see that the depth adjustment ring on the actual router is part of the motor assembly:
Moreover, the depth adjustment ring is allegedly removable (e.g., if you're planning to attach the plunge base), but I cannot budge it.
Obviously, I don't really care whether the diagram is accurate; I just want to be able to use the router. Is there something I'm missing? Did I buy defective merchandise? What is going on here?

Ok, revised my answer
I found the instructions here and the information is on page two under "Set-up: Fixed and D-Handle Base - ADJUSTING THE DEPTH OF CUT (FIG. 1, 3)"
Occurring to this there is no lock of the black adjustment ring so it should turn somewhat freely, though it might have some resistance so not to move when you don't want it it.
It's very possible that your adjuster (piece B) is stuck. As it is, it is 'bottomed out' at max depth setting and it might have been tightened in this direction too far causing it to be stuck. If you feel save that you won't break it, turn the adjuster in the direction of the grove going away from the power head, this should be obvious. Once unstuck it should turn freely
If this doesn't work, or you don't feel comfortable trying the above, then return it as it's not working as intended.
