Unfold Stop Adjustment
This applies to 2013+ 2-Point 5-Section applicators only.
Refer to Figure 57
During unfold (FOLD / FIELD switch in FOLD), the inner
wing sections
are intended to stop 0 to 5° above
wings-level relative to the center section . The stopping
point is controlled by a vertical proximity sensor at
each center/wing hinge. If a wing does not stop in this
range, adjust the proximity sensor.
1. Verify that the misalignment is not caused by air in
the hydraulic system. Do not use the proximity
adjustment to compensate for hydraulic problems.
2. Move the applicator to a level surface. Raise and fold
(page 49). Install lift-assist lock channels (page 38)
and parking stands (page 31).
3. Set the FOLD / FIELD switch to FOLD. Extend the
fold/lift circuit to unfold until the inner wings stop.
Set the circuit to Neutral. Shut off the tractor.
4. Check the sensor-actuator ( - ) gap at the
affected wing pivot. With the actuator near the
marked region on the sensor, the gap must be:
1
/
8
to
1
/
4
inch (3.2 to 6.3 mm)
If the gap is incorrect, correct that, at the current
sensor height. Fold and unfold to see if further
adjustment is required.
5. To adjust the sensor, loosen the bolts securing the
sensor
to the bracket. Do not adjust the
actuator position.
To lower the angle at which the wing stops, raise the
sensor.
To raise the angle at which the wing stops, lower the
sensor.
6. Secure the bolts. Fold and unfold to test.
