Four-Cylinder Shared Supply Circuit
If the supply hoses are a dedicated marker circuit, use
the instructions at “Dedicated Supply Circuit Hose” on
page 7. If the kit included a tee, rather than a cross
,
use the instructions at “Two-Cylinder Shared Supply
Circuit” on page 8.
29. Select the two supply hoses . See the table on
page 6 for the correct part number for the planter.
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.
Refer to Figure 10
30. Select two sets new:
811-147C CR 3/4MJIC
Remove any protective caps from any three ports.
31. Locate the existing tees at the rear ends of the
hoses to the hitch. Perform the next step separately
for lift and lower hoses, to reduce the risk of
reversing the circuit at re-connection.
32. Remove one:
811-078C TE 3/4MJIC
Replace it with a cross . The removed tee is not
re-used.
33. Select two new:
811-150C EL 3/4FJIC 3/4MJIC
Remove any protective plug from the FJIC end of
the elbow
. Remove any protective cap remaining
on the cross . Connect the elbow to the cross,
with the MJIC end oriented up.
Install Supply Hoses
34. Remove any protective plug from one end of each
supply hose. Remove any protective cap from the
MJIC ends of elbows
. Connect one hose to each
elbow.
