proper indexing of the adjustment numbers from blade to blade or after cleaning

If you use Feather blades - and there is some consensus that they are among the best - start at the very lowest setting and then crank it up 1/2 to 1 notch each pass. The higher the number, the more facial hair it will grab onto, and if the number is too high it will try to get too much at once and you'll get nicks. With other blades, the higher settings (3+) might be useful, but with Feathers I've never found it necessary. Naturally, everyone has different coarseness to their beard hair, and perhaps the shaving soap you use is different from mine, so maybe your best place to start is 1.5, or 2. But I'd start at the absolute minimum and only advance it once that setting has done as much as it will. You should also try to make as few passes as possible, since more will irritate the skin.

How are blades inserted? Is it a butterfly action?

No. This is not a butterfly opening safety razor. This is a three-piece unit. The top blade head is two pieces that hold the blade in place, and when together, the two head pieces screw onto the base.

Can this shaver be used to shave private parts, shave your head, etc? I've experience bad results with none adjustable types.

Not with this type of razor or a set of irons Brother. They do make razors suitable for the head which I've seen that are round in shape check them out.

There are no instructions with razor. Besides rinsing in warm water, what else do you have to do to clean it and keep it functioning correctly?

Each week, I take it apart as if I were changing the blade, and remove the blade. Then I scrub it with some anti-bacterial hand soap using an old toothbrush and hot water. I rinse it clean, shake off the excess water, then reassemble. That process seems to work good for me.
