Without looking through the ladder, my first guess would be that the tool isn't unclamping and that is raising the rest of the alarm states. Will the tool manually unclamp?

I've manually rotate the cam motor to check the cam condition, the twin rotates and unclamp cylinder and drawbar goes to unclamp state and moves back to clamp state as i rotate the cam motor.

Now I've put the air bleeding procedure, M120 cycle functions and M121 cycle not functioning. I've Unclamped manually in selector switch, it's unclamping, when I try to clamp stops midway. I rotate the cam motor and positioned. Try again, same problem.
