F39 Time too long cutter backward
Possible cause:
All solenoid valves are de-energized.
The cutter has been moving inward for more than 30 seconds.
This error can occur in the automatic mode only.
Rectification:
Check the cutter for mechanical obstructions.
Check the cutter motion valve.
Check the output card, coils and wiring.
Check the cutter limit switch.
Check that the pumps are supplying sufficient hydraulic oil to the system.
The coil of the solenoid valve is defective. Exchange the valve for an identical new item.
