step. The Pressure Reduction Valve Manifold is
designed to not allow reverse flow. If the pressure
gauge immediately reaches 3000 psi, the hydraulic
connections need to be reversed.
5. With the circuit running, open the RED handled Ball
Valve (align the handle with the hydraulic lines
entering and leaving the valve).
6. Monitor the pressure gauge. It should read
approximately 2000 psi.
7. With the pressure holding steady at approximately
2000 psi CLOSE the RED handled Ball Valve.
8. Turn the circuit OFF at the tractor. There should be
no need to adjust the system pressure unless the
system develops a leak or there is a significant
change in the ambient temperature.
IMPORTANT
Should it become necessary to work on the system,
the hoses, or the shank cylinders it will be necessary
to dis-charge the system before opening the
hydraulic system.

DANGER
To Dis-Charge The Hydraulic System:
1-5. Follow Steps 1 through 5 from “To Hydraulically
Charge The System” Instructions.
6. Monitor the pressure gauge. It should read
approximately 2000 psi.
7. OPEN the Dump Valve by turning the knurled knob
1/4 turn counter-clockwise.
8. The pressure gauge should quickly drop to “zero”.
9. If the pressure does not completely zero out, idle the
tractor and reduce the circuit flow.
10. When the pressure is zero, turn the hydraulic circuit
off and shut the tractor down.
11. DO NOT ATTEMPT TO OPEN THE CIRCUIT
UNLESS THE PRESSURE IS ZERO!
12. Carefully crack a hydraulic fitting where any flow can
be collected. Expect some residual pressure and
flow. Once the pressure is confirmed to be
alleviated, it should be safe to open the hydraulic
system as needed to complete the work to be done.
The Accumulator and the Hydraulic System
supporting the Hydraulic Shanks contains high,
stored, energy. Do not attempt to charge /
discharge the pressurized gas from the
Accumulator. Do not attempt to open the
Hydraulic System without following the
prescribed procedure below. Failure to heed or
comply with this warning can result in serious
injury or death.
