CLAAS A097h: Fault in 4 valve

The 4 valve does not reach the float position within the time set. The problem may be linked with oil viscosity (temperature too low) reducing the performance of the valve. The 4 valve returns to neutral.

   Operation of the 4 valve

3. 3

   Tractor warming procedure

1. 1

   Let the tractor warm up

   Allow the tractor to warm up and test the operation of the 4 valve again.

2. 2

   Check oil viscosity and temperature

   Ensure the oil viscosity is appropriate for the current temperature, as low temperature may reduce valve performance.

3. 3

   Replace the 4 valve

   If the error appears again after warming up and checking oil conditions, replace the 4 valve.
