2. WING FOLD/UNFOLD: Press SCV II selector button (A) and turn flow control knob (B) to fast (rabbit) position.

3. Turn time detent knob (C) until display reads "19" seconds. If this is not enough time to completely fold/unfold wings, the time detent button (C) may be set to constant. However, the tractor hydraulic pump will continue to operate after the fold/unfold cylinders have stopped moving. Shutting off pump by moving SCV lever to any position after lever has returned to NEUTRAL is recommended.
