6. Tractor does not start off
Cause
Remedial Action
Actuator not functioning. Mechanical Auxiliary mode.
No operating range selected. Select operating range I or II. Use auxiliary lever,
if necessary.
Adjustment not functioning. Measure servo pressure (too low).
Inlet circuit does not work. Measure feed and outlet pressure.
Leak in the main circuit. Measure feed and outlet pressure.
Internal leak in the main circuit. Check transmission characteristic (at workshop).
High-pressure limiting valve does not shut. Measure control pressure.
Flush valve stuck open. Start off in the other directon of travel
Transmission characteristic not programmed. Record the transmission characteristic (at
workshop).
Rpm adjustment not set. Set the rpm adjustment.
7. Transmission oil temperature too high
Cause
Remedial Action
Cooler soiled. Clean the radiator.
Heavy traction in operating range II. Switch to driving mode I.
Clutch operated over extended period. Fully engage the clutch.
Turboclutch function active for long period. Increase engine speed.
Leak in the main circuit. Measure feed and outlet pressure.
Leakage in feed circuit. Measure feed and outlet pressure.
Leakage in outlet line. Measure outlet pressure.
High-pressure limiting valve does not shut. Measure control pressure.
Internal leak in the main circuit. Check transmission characteristic (at workshop).
8. Interruption of tractive power while reversing or during
acceleration-deceleration changes
Cause
Remedial Action
Flush valve stuck open. Replace purge valve.
High-pressure limiting valve does not shut. Replace high-pressure limiting valve.
9. Tractor no longer reaches maximum speed
Cause
Remedial Action
Incorrect transmission calibration. Record the transmission characteristic (at
workshop).
Adjustment does not function properly. Measure servo pressure (too low).
Leak in the main circuit. Measure feed and outlet pressure.
