1. Check hydraulic oil level. Fill if necessary.

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, time detent button can be set to constant. If set to constant, tractor hydraulic pump will continue to operate after fold/unfold cylinders have stopped moving. This is normal and not harmful. However, shutting off pump by moving SCV lever to any position after lever has returned to NEUTRAL is recommended.

   NOTE: Use constant for machines equipped with hydraulic control.
