Two-Cylinder Shared Supply Circuit
If the supply hoses are on a dedicated circuit, use the
instructions at “Dedicated Supply Circuit Hose” on
page 7. If the kit includes a cross (not a tee
), continue
at “Four-Cylinder Shared Supply Circuit” on page 9.
23. Select the two supply hoses . See the table on
page 6 for the correct part number for the planter.
Replace Existing Elbow
Refer to Figure 9
24. Select two sets new:
811-078C TE 3/4MJIC
Remove any protective caps from the center port
and one end port.
25. Locate the existing elbows . Perform the next
step separately for lift and lower hoses, to reduce
the risk of reversing the circuit at re-connection.
26. Remove one:
811-725C EL 90 3/4MJIC
Replace it with a tee . The removed elbow is not
re-used.
27. Select two new:

High Pressure Fluid Hazard:
Ensure lift circuit pressure is zero. Wear gloves and safety
eyewear when working on hydraulics. Dangerous releases of
hydraulic fluid may occur if pressure remains in the circuit.
This could lead to serious personal injury. If hydraulic fluid
penetrates the skin, seek immediate medical attention from a
physician familiar with this type of injury.
