Maybe a bad cylinder. Raise it up and block it. Remove your lines and cap the cylinder, then remove the blocks and if it drops your cylinder is bad. if it holds then your problem is up stream, lift valve or check valve. I do not have that unit so I am not looking at a schematic of the hydraulics, but this should be a fast and easy enough test to point you in the direction of trouble.
