Ah. Easy. Reseal the primary lift cylinder. You are gonna find either the piston seal is crumbling or the small check valve in the center of the piston has trash in it. I suggest to always pull the snap ring when resealing this type cylinder to replace the outer small oring as they sometimes fail. Anytime you have these style cylinders (they are not a true displacement style, and nobody seems to know the name of them) and the secondaries begin lifting before the primary has staged all of the way up, it indicates that oil is gotten above the piston seal. You can usually force the mast all the way up once empty and this corrects the staging for a short while till the oil gets past the piston again.
