Woods BH75 Pressure hold issue

[Jass]

I have a new-to-me 2006 Woods BH2500-1 frame mounted backhoe with a Woods PTO hydraulic pump and the pressure does not hold. The backhoe digs fine and has seemingly good downward digging pressure, but if you raise the boom and the outriggers all up completely they all immediately start to lose pressure and begin dropping towards the ground. The fluid level in the onboard tank is full. Has anyone else experienced this issue? Any thoughts on what the issue might be that is causing this issue? Any/all help appreciated

Thats three seoarate circuits and there are basically two routes for that leakdown to occur:

1) Via the seals in the cylinders
2) Via the spools in the control valve.

Easy to diagnose which way its going. Fixing it maybe not so easy.
