I've also got Hynautic with upper/lower stations. The problem of losing the
upper station is not uncommon, and is due to air in the lines, which rises.
(Gravity, etc.)
You need to check/correct the fluid level in the tank, pressurize it, then
purge the air out of the upper station and it's lines.
Back by the ram & tank, you'll find a relief valve. A hydraulic line in
each side goes to the ram, a line in the bottom goes to the tank, and there's
a pair of screws with locknuts on the top. Back these screws off until
pressure is removed from the internal springs. Don't unscrew it completely or
you could lose it. Now, go to the upper station and turn the wheel about 20
turns to starboard - just keep cranking it over. Then, turn it 20 turns the
other way. Finally, check fluid level in the tank (correct as required) and
screw in the screws on the relief valve.

Also, if you have the book on your particular model RAM, it will tell you
how many turns you should have lock-to-lock (with the bleeders closed).
Mine is 3 turns. That way you can tell when you have all the air out.
