I always have to adjust by rotating the router body in the base. This
is a very course adjustment making it difficult to get the cut depth
set right.

When I try to use the fine adjustment ring it doesn't seem to do
anything at all -- it just turns and turns but the blade does not rise
or lower. What I am doing wrong?

Jim,
The only thing you are doing wrong is confusing the purpose of the
ring. That is not a fine adjustment ring, it is simply a place-marker.
You turn it so that the zero mark lines up with one of the reference
marks on the body of the motor. Then you twist the motor so the
reference mark moves to the desired mark on the ring. The ring is just
a friction fit and is not threaded at all. There is no fine adjustment
other than a very slight twist of the motor in the base.
