Initialize the System
66. Set the selector valve to Auxiliary
If the implement or tool for which this kit was installed
cannot tolerate air in the lines, perform step 67 through
step 69. Otherwise, skip to step 70.
67. Connect a male-to-male (Quick Disconnect)
hydraulic hose between the two Auxiliary ports at
the seed cart.
68. Activate and marker hydraulic circuit, and run it for
30 seconds in Extend, and 30 seconds in Retract,
to clear air from the line. Check for leaks at all new
and re-made connections.
69. Set circuit to Float and disconnect the hose.
If the implement for which this kit was installed is not
sensitive to hydraulic flow direction, skip to step 73.
70. Connect the external implement for which the kit
was installed (such as an auger). If the implement
hoses are marked Extend/Retract or Base/Rod,
connect the Extend/Base hose to the left Aux port.
71. Briefly set the marker circuit to Extend, and check
implement operation.
If operation is correct (for example, auger lifts),
mark the left Aux port “Extend”, and skip to step
73.
72. If operation is incorrect at step 71, briefly set the
marker circuit to Retract, and check implement
operation.
If operation is correct, mark the right Aux port
“Extend”.
73. Set tractor marker circuit to Float, and disconnect
implement at Aux ports.
74. Set selector valve to Marker.
75. Perform several Marker re-phase operations (see
planter Operator’s Manual). Check for leaks at all
new and re-made connections.
