A brief push of that button would unlock the syste= m.

=0AAgain,

My Oildyne internal pressure switch came (set by Oildyne= ) at 1,500 PSI. How do I know? I parked my plane on the ramp at Newport New= s, Va in the evening. The temperature was 40=B0F. 3 days later, when I was = going to take off. The temperature was 80=B0F. I looked at my pressure gaug= es. Both the up and down were at 1,500 PSI. I had to crack a nut in a hydra= ulic line to release the pressure. The gear would not go up or down, at thi= s pressure. The emergency dump valve would not release, at this pressure. T= he pump would not run at all, at this pressure.

Now, I have Wolfgang= 's high pressure adapter in the system. It runs the pump whenever the press= ure is high on both the up and the down side.

There is no speculatio= n here. Just the facts, mam.
