There are no visible fluid leaks.
The RVA web site suggests the problem is caused by the retract valve (stem).
It seems that the same jack would settle each time if that were the problem.
Specks of dirt in the fluid can cause intermittent jack "leak down" on any of the 3 individual RVA jacks.
Running each individual jack up manualy, (and/or simply lossening and re-tightening the manual valves), may cure the problem.
It did mine.
