XJ2025H not enough lift strength

If your right hand cylinder seals are bad the fluid is bypassing pressure internally in the cylinder. Could be the issue. Test it by raising the FEL a foot or so from the ground, remove hoses on the suspect cyinder & plug both ports & the hoses. The you can lower the FEL (not running the engine). If it lowers down then you know the cylinder is bypassing.
