Opener Operation - Continued
Relieve System Pressure
To bleed all pressure from Opener hydraulic system:
• Open “Operating” valve to service/bleed-off
position.
• Lift openers to transport position.
• Put tractor remote in “float” position.
• Let openers drop and pressure go to 0 psi (or near
0 psi) on gauge.
• Lift openers to transport position and lock
“Openers” valve.
Normal Operation
• Set operating pressure as described under “Setting
Maximum System Pressure”.
• Ensure the “Operating” valve is turned in to operating
position and the “Openers” ball valve is set to
unlocked position to allow oil flow.
• With the Contour Air Drill moving forward, lower
openers into the ground. Hold tractor hydraulic
lever until the maximum preset operating pressure is
reached (see “Setting Maximum System Pressure”).
This ensures that all of the openers are fully charged
and engaged.
• When turning at head land, the openers do not need
to be completely cycled from working to fully lifted
position. The openers can be lifted just to the point
that they do not contact the ground. This will reduce
the time required to fully recharge the hydraulic
accumulator to the preset operating pressure.
• Avoid sharp turns with drill in ground. Turns sharp
enough to cause the inside openers of the air drill
to reverse direction may cause openers to plug.
Note: Under “Normal Operation” the valve block
will maintain the set system pressure in the
accumulator when openers are raised.
