SECTION 2 – CONNECTING AND SEQUENCING WING LIFT
4. Before raising outer wings for the first time, make sure wing lift cylinder attach eyebolts are
loose.
– Slowly raise part 2 wings into transport position.
– Fully retract part 2 cylinders and let wings rest against transport supports. Test adjustment
of sequencing valve before turning set screw. If valve is set with too much pressure, part 1
wings will not rise. To reduce the amount of pressure, turn set screw outward.
– With cylinders fully retracted and part 2 wings resting on transport supports, adjust cylinder
attach eyebolts so cylinders allow lift link rollers to rest on the bottom of slot. Tighten nuts.
5. Before raising part 1 wings for the first time, make sure cylinder attach eyebolts are loose.
– Slowly raise wings by fully retracting part 1 wing lift cylinders, allow wings to rest against the
transport locks. If wing does not rest against both locks, adjust locks accordingly.
– Tighten cylinder attach eyebolts so cylinders allow part 1 wing lift rollers to rest on the bottom
of slot.
6. Lower wings to field position.
– Make sure the part 1 wing lift cylinders fully extend before part 2 wings start to move. Test the
adjustment before turning set screw. If the valve is set with too much pressure, the part 2
wings will not unfold. To reduce the amount of pressure, turn set screw outward.
7. Fold and unfold machine again to make sure that everything is working properly.
