Quick Jack Assistance is Needed Please., One side is stuck up Options

[913B]

If anyone had run into this before or have any helpful tips, it would be appreciated. If not no worries I plan to call their troubleshooting hotline Monday.

I was able to lift a vehicle up then down, didn't really come all the way down but good enough to slide the QJ out and pretty much applied my weight on them to finish going all the way down. Curiosity got the best of me so I lifted them with no weight they both went up. And only one came back down slowly. The other side appears to be stuck and would not come down or up. It is currently stuck in the up position.

The thing I have tried is to ensure the side tank was pressurized to 50psi.
I tried swapping the hydraulic lines still that one side won't move. The other side works fine up and down. So it seems it's not the lines or the hydraulic unit. But the that particular cylinder?

Any thoughts for the weekend.

Thanks, everyone!

The Quick Jacks need weight on them to come down. Put a couple of cinder blocks on the one stuck in the up position, then hit the down function on the control button. If that doesn’t work, then slowly open the bleed screw on the offending lift, but don’t get your hand or fingertips caught when it crashes down!
