If above procedure still fails to position landing gear as desired:

12. Landing Gear Motor Circuit Breaker – FULL.

13. Landing Gear Switch – DESIRED POSITION

14. Hand Pump Position Selector – PLACE IN DESIRED POSITION

15. Emergency Hand Pump – PUMP until resistance becomes heavy (may be 100 or more cycles)

16. Gear Position – CONFIRM VISUALLY

WARNING ! !

Do not attempt to land on water unless all four wheels are fully retracted.
