My apologies. I assumed there would be something in the flight manuals about this.. and similar requests often come from Flight Simulator enthusiasts ; )
I don't know about the MD11 panel, but I can't imagine anyone running a 747-400 panel without hands-on training.... There are simply too many system quirks and things which can go wrong. Even people who have been trained will need refresher courses if they haven't been exposed to this on a regular basis.
You should probably consult your training department or, failing that, allow yourself some extra time during the walkaround to climb up on the refuelling truck with a trained operator.
Rgds.
