10.2 HYDRAULIC SYSTEM

10.2.1 Hydraulic Oil Change

An oil and filter change is recommended annually
or every 400 hours of operation using an AW HVI
Hydraulic ISO 32 oil.
IMPORTANT
Never run the hydraulic pump unless the hydraulic
oil tank is full (indicated in sight level gauge).
1. Place a large waste oil container under
the inlet hose. The hydraulic tank holds
approximately ten gallons of oil.
2. Drain the hydraulic tank by removing the inlet
hose from the pump. Allow the tank to drain
completely.
3. Remove and replace the oil filter. Apply a thin
coat of oil to the rubber seal of the new oil
filter. Hand‑tighten only.
4. Reconnect the inlet hose to the pump.
5. Fill the tank to the fill line at the top of the
gauge with approximately ten gallons of AW
HVI Hydraulic ISO 32 oil. Replace the cap.
6. Start the engine and cycle all the cylinders
several times.
7. Recheck the oil level in the tank and add as
needed.
10.2.2 Hydraulic Pressure Relief
Valves
IMPORTANT
There are two pressure relief valves (1 and 2)
which have been factory preset for the most
efficient operation of the seed tender. DO NOT
adjust these relief valves. If the unit is not
operating properly, refer to the Troubleshooting
section, call an authorized dealer, or call the
factory.
