Free lift cylinder not moving

My free lift cylinder is not going up, instead the outer stages go up first. I got a new seal kit coming but I am not sure thats the problem. Also someone before installed a new diverter/ flow control valve and I am not sure it was hooked up properly. I cant find a hydraulic diagram for the life of me. The model on the lift mechanism is E50MT043 00039M. Any help would be appreciated.

looks like you have a lift tek mast you can download service and parts manuals online from their website you may also be bypassing on main lift cylinders also we had that occur in the past repack the free lift and it still drifts down we pulled the main lifts found the bottom seals blown and dry rotted
