Opener Operation - Continued
Setting Maximum System Pressure (Trip Out Force)
Important
Do not exceed 4 times the nitrogen pre-charge
pressure or 1200 psi, whichever is the lower
number.

• To determine the approximate trip out force in pounds
on each shank, divide the system hydraulic pressure
in the circuit by 1.5.
For example: A system hydraulic pressure of 750 psi
(5171 kPa) would be approximately 500 lbs (227 Kg)
trip force at each shank.
Note: Due to the variation of friction effects, this
trip force is approximate.
• Maximum hydraulic operating pressure can be set
by dialing the reducing valve in to increase allowable
pressure, and dialing it out to decrease allowable
pressure. This adjustment is done in order to set
a maximum working pressure; pressure can be
decreased below the set point and increased back
up to the set point on the go from the tractor.
1. Ensure the “Operating” valve is set to operating
position and the “Openers” ball valve is set to
unlocked position to allow flow.
2. Begin by dialing the adjustment all the way out on
the “Pressure” valve.
3. Dial the “Pressure” valve setting in 1 full turn.
4. Operate the tractor remote to pressurize the
accumulator circuit. Once the pressure has
stopped climbing check the system pressure on
the gauge.
Note: Set “Pressure” valve pressure 100 - 150
psi above the desired working pressure
in order to allow for pressure drop from
accumulator cooling and valve hysteresis.
System pressure will level off and hold after
approximately 1 minute.
5. If the pressure in the system is high enough
to achieve the desired trip out force, setting is
complete. If the pressure is too low, relieve the
circuit pressure using the tractor remote and
repeat steps 3 and 4 until the desired pressure is
achieved.
6. If the system pressure is too high, relieve the circuit
pressure using the tractor remote, and then dial
the “Pressure” valve adjustment out incrementally.
Repeat step 4 until the desired system pressure
has been reached.
Note: Operate system at the lowest system pressure
that will keep shanks locked vertical during
seeding and provide adequate packing
pressure. Excessive hydraulic pressure may
disturb rocks and damage carbides.
