Hello all, just got my first forklift. Crown FC-4500. No tilt action on it. I can hear a pump activate but nothing moves, just sounds like it is straining to move the tilt cylinders but it can't. I'm new to forklift ownership, so have no experience with this machine. I checked the switches on the lever with continuity tester, seem fine. If suspecting a hydraulic malfunction isn't out of the question, should I look at the solenoid on the counterbalance manifold? Apparently it allows return flow from the tilt cylinders. Or the counterbalance valve in the same body? The wires to the solenoid show current... though even so when the tilt lever is at rest. Also, shows Event ID: 331. Nothing in the cheap manual I downloaded about that. I see some "tilt enable,disable" settings in the service menus but I'm locked out of that, no Pin/pw. Appreciate any thoughts! I would just pull that solenoid out to test but am afraid I'd lose a ton of fluid... or?
