be bleed out of system as follows:
To bleed hydraulic system of air:
• Lift openers up and lock tractor remote in lift
position.
• With tractor hydraulics operating, open bleed-off
ball valves on end of drill wings.
• Allow oil to cycle for a few minutes then change
direction of tractor remote to lower openers and
cycle for a few more minutes.
• Close bleed-off ball valves and lift openers up.
• Repeat above procedure for a second time.
• Close bleed-off ball valves and lift openers up.
• Lock “Openers” valve and check to see that
openers stay firmly in position.
• If openers are spongy repeat procedure until air is
gone.
HIGH-PRESSURE FLUID HAZARD
To prevent serious injury or death:
• Relieve pressure on hydraulic system before
servicing or disconnecting hoses.
• Wear proper hand and eye protection when
searching for leaks. Use wood or cardboard
instead of hands.
• Keep all components in good repair.
