Hyd slide out creeping out when closed is caused by
1. Air in system. Cycle slides in and out 3 to 5 times to purge air
2. Internal or external leak on slide actuator
3. Hydac solenoid valve .. only one for hyd slides nit fully closed in manual override mode CW) or sticking valve
DO NOT use a bar or anything else to keep hyd slides closed .. 2000 psi is used to keep slides closed or open and if leak is internal on actuator your can tear up your slide by locking in place
Thanks for your reply. I'll try purging air out this weekend. I know it's not an external leak on cylinder because no sign of fluid anywhere. Could be an internal leak. I'll see what happens after I cycle the slides in and out a few times.
