To function properly, the hydraulics must be free of air. If hydraulics have not been bled, they will op-
erate with jerky, uneven motions and could cause wings to drop rapidly during folding or unfolding.
If hydraulics were not bled during initial implement setup or if you replace a part in hydraulic system
during the life of the implement, complete the following procedures:
BLEEDING FOLD HYDRAULICS
1. Check hydraulic fluid level in tractor reservoir and fill to proper level. Add fluid to system as needed.
2. With implement unfolded and fold cylinders completely extended, disconnect rod end pins and swing the cyl-
inders so they will not contact anything when extended.
3. Loosen rod end hose fittings (1) at a ORB connection.
4. Slowly supply oil to rod end of fold cylinders until oil appears at loosened hose fitting. Tighten fitting and com-
pletely retract fold cylinders.
5. With cylinders completely retracted, loosen base end hose fittings (2) at ORB connection.
6. Slowly supply oil to base end of fold cylinders until oil appears at loosened hose fitting. Tighten base end hose
fitting and cycle fold cylinders in and out several times.
7. Re-pin cylinder rod clevises.
