Hydraulic jacks at full extention

When one or more of my hydraulic jacks are at full extension, other jacks seem to stop working. Is there a problem here? Is there a bypass valve that operates when a jack is full out? Thanks in advance to those who can add some light.

Can't answer your question, BUT you want to avoid extending your jack full extension when ever possible. If you place blocks under the jacks, you will find they will be more stable as less amount of the rod is sticking out. JMHO

I agree, I like my jacks to be extended as little as possible.

I was also thinking oil. Perhaps tank is empty when jack fully extended.

Agree!! I over extended one of my jacks and instead of stopping it blew a seal.

Nope, it will blow the end out, not just the seal. Seal fails from debris on piston.
Jack in or out, same pressure on the seal while lifting.

Are you sure you are not getting an overtravel indication. When a jack reaches the full travel and it is not level it will give over travel indication and then shut down the hydraulics for all jacks

That is a distinct possibility, and the first thing I would check. Make sure to retract all jacks before checking/adding oil, otherwise you will have a mess then next time you do retract them!
