Setting the Dump Valve Delay:
a. Ensure all dump valves and harnesses are plugged in securely, and dump valves are functioning
properly.
b. Adjustments will be made in increments of .25 seconds.
c. Proper action should be: when raised, row cleaners come up and stay. When lowered, dump valves
will fire, row cleaners should come to ½ travel (or to when the linkage is parallel), at which time the
dump valves will close, then row cleaners will fall back to preset pressures slowly.
d. Access the dump valve delay screen on your cab controller.
e. Adjust to .5 second delay, revert to home screen.
f.
Press the dump I button and observe row cleaners, it is best to have a second person looking as

screen.
