Hydraulics is one of those things.... that if not used regularly, things tend to deteriorate. Seals dry and can crack or chip. Pump internals can do the same thing.... causing less flow and/or pressure. If the press has set for a long time, it could be any number of issues. I would start by changing the oil/filter(s)..... but remember that some machines/systems use only a specific type of hydraulic fluid...and mixing them usually is "bad ju-ju".

Having sat for a long time, you want to be VERY observant of hoses....those will also dry out/crack, and a pin hole, depending on pressures, could be deadly.

Not trying to scare you, but far too many simply don't understand the forces being dealt with when it comes to hydraulics. And in this case, ignorance could kill you.
