flow (page 76).
2. Close the weight-transfer shut-off valve (page 48).
3. Retract the fold cylinder circuit until the wing locks
stop motion, or the outside row knives or tines just
start to lift out of the ground. Set the fold circuit to
Neutral.
4. Raise the 2-point hitch.
5. Extend the lift-assist cylinders to raise the applicator
rear.
6. Wait for the applicator lines to discharge.
7. Activate lift-assist again, in case the cylinders have
settled during discharge.
8. Cautiously approach the rear of the applicator.
Install lift locks at the rear casters.
9. Deploy parking stands if the applicator is to be
parked at the folding spot.
Refer to Figure 44
(depicting an NP40L, which has similar wing locks)
10. Swing the wing locks up and out of their engaged
positions, and into their reset positions.
11. Retract the fold cylinders until the wings contact the
transport rest. Set circuit to Float if unhitching, or
Neutral for transport.
For parking/storage/service, lower the applicator onto
parking stands. For transport, the lift-assist circuit may
be left in Neutral fully raised, or lowered onto the lock
channels and set to Float or Neutral.
