All of our attachments are sealed when we remove them with no pressure relief.

Hi JJ,
I heard the same thing from Terry and I have mentioned it here before. I have needle valves in line and if i lock those down, the lift arms stay.
I am not sure how other manufacturers deal with pressure relief when the circuits are closed. I suspect they just do not worry about it.

I have to admit that is what i assumed the leak down was from.your valve spools are leaking.
In general, you can say that about anything hyd.
However there is an acceptable leak down rate that they use to replace valves and cyl when new.
Prince engineers use 10 cc per min.
