OPERATION AND MAINTENANCE
Hydraulic Accumulator / Shanks
Operation
WARNING
Escaping hydraulic fluid can cause serious
personal injury. Relieve system pressure before
repairing, adjusting, or disconnecting. Wear
proper hand and eye protection when searching
for leaks. Use cardboard instead of hands.
Figure 4-2.
Keep all components (cylinders,
hoses, fittings etc.) in good repair.
Figure 4-2: Hydraulic Leak Detection
The 2512 Rigid and Folding In-Row Ripper may be
equipped with the Hydraulic Reset Option. The Hydraulic
Reset Option utilizes a factory-charged gas Accumulator.
The Accumulator needs to carry an additional hydraulic
charge to do field work.
See Figure 4-3.
The hydraulic charge needs to be greater in magnitude
than the nitrogen pre-charge to create an oil reserve
within the Accumulator to maintain working pressure in
the event of a small loss of oil from the system or a
change in ambient temperature.
The ripper does not need to be connected to the tractor
during field operation but connecting the lines to the
tractor will keep them out of harms way.
The Ball Valve between the Pressure Reduction Valve
Manifold and the machine system needs the be turned
"OFF" during field operation. The Ball Valve should only
be opened to 1.) check the system operating pressure
present, and 2.) adjust the system pressure if it is too
high or too low (below 2,000 psi).
The Pressure Reduction Valve is pre-set at the factory to
have a hydraulic output of 2,000 psi. The Pressure
Reduction Valve will increase the hydraulic pressure of
the system to 2,000 psi if it is less than 2,000 psi and will
allow oil to pass back to the tractor if the system pressure
is higher than 2,000 psi thereby reducing the system
pressure.

See
See Figure 4-4.
The pressure gauge will not monitor the system pressure
unless the Ball Valve is opened, but the valve should
remain in the "OFF" position unless the operating
pressure is being checked or adjusted.
NOTE
If the system continuously loses pressure, contact
Landoll Company, LLC and request to speak with a
technician.

To Hydraulically Charge The System:
1. Connect the pressure and return hydraulic lines
connected to the Pressure Reduction Valve Manifold,
to the tractor.
See Figure 4-4.
2. Make sure the Dump Valve (knurled, knob) is "OFF".
3. Make sure the
RED
handled Ball Valve is closed. DO
NOT open it at this time.
4. Activate the appropriate tractor circuit connected to
the Pressure Reduction Valve Manifold in the first
