1) Position the opener lock handles (1) in FIELD posi-
tion (3).
2) Raise the openers completely to release the spring
loaded locks.
3) Lower the openers.
How To Set Opener Hydraulic Down Pressure:
Note: The following information assumes the tractor is
either a closed center and/or load sensing system.
Open center tractors can not be ran in continuous
flow (see Open Center Hydraulic Instructions on pg.
6).
1) Turn the locking disk (1) counterclockwise to
enable adjustment.
2) Initially close the bypass valve for no oil flow by
turning the adjustment knob (2) completely clockwise.
Note: Turn the adjustment knob counterclockwise to
increase flow and clockwise to decrease flow. Turn it
fully clockwise to stop all bypass flow.
3) With the tractor at half throttle, adjust the flow-con-
trol valve on the tractor so the openers raise and
lower at a reasonable speed. Keep the tractor at half
throttle for the remaining steps.
opener raise and lower, the greater potential for oil
heating, premature wear, or tractor damage.
4) Engage the tractor hydraulics and lower the open-
ers. Lock the hydraulic lever on the tractor for continu-
ous operation.
5) Release the locking disks (3) on the down-pressure
valves.
6) Turn the adjustment knobs (4) on the down-pres-
sure valves so the gauges are at 1800 psi (2100 psi
for heavy duty drills).
7) While watching the gauges on the drill, slowly
adjust the knob on the bypass valve counterclock-
wise. Adjust the bypass valve just until the needles on
the gauges begin to move down.
time, for proper opener operation, the bypass valve
must be set at least 300 psi above the opener down
pressure setting with the tractor at half throttle.
8) Lock the bypass valve at this setting.
9) Readjust the down-pressure valves on the drill to
the desired opener down pressure.
