Bobcat 943 Hydraulics operates in only one direction

[Robertsroost]

Bobcat 943 Hydraulics operates in only one direction, I accidentally ran the system low on fluid and now the arm will now only go up and the bucket will only tilt down in one direction.
I have cycled the system by raising and then shutting the engine down and cycling the pedal until the bucket comes back down under its own weight. I also have bled the system by cracking lines at the the cylinders. Need your help.
Thanx!

Try checking the safety switches under the seat I had that problem once and switches had stopped so I by passed them at hydraulic controls
