hydraulic slide opens premature

[bartiee]

when slide has been closed for about a week,it opens a little by itself. Any support?

When operating the hydraulic slides pressure build. When you stop movement pressure remains between the pump and valve or cylinder. I find to relieve the latent pressure I can cycle the selector valves on the other slides and I can hear the pressure dump back to tank. Does that make sense?

thanks donn0 I'll try that

Valve leaking allowing the pressure to bleed off. Do you have selector valves? If so, cycle them a couple of times and see what happens.
