Genie telehandler tilt and self-leveling problem.

Hello, we're working on a Genie GTH-2506 telehandler. When you want to tilt the forks it'll go the opposite direction before going the desired direction such as if you're tilting down and then want to tilt back it will tip front before going back and vice versa. Also there seems to be a problem with the self-leveling in that the short cylinder behind the cab got bent in a U-shape, we got the cylinder repaired and it mostly works now except when you have the forks rolled back the whole way and try putting the boom down that same cylinder gets all tight and doesn't retract, so I'm afraid there's still a problem somewhere. I don't know if these two problems are relating, but any help would be greatly appreciated. Thank-you!
