JLG Scissors lift works but won't go down

Our lift won't go down unless you use the manual control, so it takes 2 people to operate it. Is there a common problem to look for? I've got a schematic but never worked on one of these before.

I also found this document which has a procedure I don't fully understand yet to diagnose the failure to go down when using the joystick. pg 88
