Folding
These instructions presume that the applicator is
unfolded and lowered.
1. Verify that the wing lock pins (page 50) are not in the
wing rest cradles. Typically they are in storage tubes.
Refer to Figure 35
2.
Set the Fold switch to
FOLD / UNFOLD.
Refer to Figure 37
Electrocution and Overhead Collision Hazards:
Do not fold with switch in FIELD position. In FIELD, the
outer wing sections cannot fold. The folded applicator would
be over 21 feet (6.2 m) high. This dramatically increases the
risk of electrocution from overhead lines, with or without
direct contact. It is also too high for safe transport.
Refer to Figure 36
3.
Raise the hitch.
4. Retract the fold/lift circuit to simultaneously raise and
fold the applicator. Observe the fold sequence. Lift
and fold do not start and end at the same time.
If an abnormal fold is detected, set the fold/lift circuit
to Retract, then Neutral at wings level. Troubleshoot
the problem.
5. Set the fold/lift circuit to Neutral.
6. Remove spacers (page 43). Install lift-assist cylinder
locks (page 50).
7. Insert wing lock pins (page 50).
8. Extend fold/lift to lower lift-assist cylinders onto lock
channels. Set fold/lift circuit to Float. Shut off tractor.
For parking/storage/service, lower the applicator onto
parking stands.
