Opener Operation
Do not back up with openers in the ground. To do so will cause
severe damage and opener plugging.
For information on opener adjustments, refer to page 41.
For more information on troubleshooting opener
problems, see “Troubleshooting”, page 50.
Marker Operation
Optional marker attachments are available from your
Great Plains dealer. Before operating markers, make
sure hydraulics are properly bled as described under
“Marker Adjustments”, page 41.
Dual markers equipped with a sequence valve are
powered off the same hydraulic circuit. Starting with both
markers folded, the folding sequence is:
1.
Activate lever - Right unfolds; left stays folded.
2.
Reverse lever - Right folds; left stays folded.
3.
Activate lever - Left unfolds; right stays folded.
4.
Reverse lever - Left folds up; right stays folded.
5.
Sequence repeats.
You can adjust marker folding speed. Refer to “Marker
Adjustments”, page 41, and adjust folding speed to a safe
rate. Folding markers at high speed can damage
markers.
