Applicator Locks

The Nutri-Pro

NP4000 Applicator is equipped with

several lock systems, which provide safety and/or

operational functions. Manual locks require operator

intervention for speciﬁc tasks. Automatic locks require no

intervention, but you may need to be aware of their

function.

Lift-Assist Lock Channels

Refer to Figure 22

These 11 inch (28 cm) length manual lock channels

are installed on the rear lift-assist cylinders for

adjustments, transport, parking, storage and raised

servicing. The locks are held in place by a bent pin .

Fully raise the applicator (page 51) to install or remove

the channels at the cylinder rods.

When not in use, the channels are stored on tubes on

the caster side faces.

Wing Lock Pins

Refer to Figure 23

These pins are manually inserted after fold, both as a

safety precaution, and to minimize wing-cradle impacts

during transport.

When not engaged, the pins are stored in tubes at the

base of the rest weldment.

See “Folding” on page 58.

Outer Wing Fold Latches

Refer to Figure 24

These latches are automatic, and should never require

operator action. The latches couple the outer wing to the

inner wing when folded, preventing movement of the

outer wing during transport (the two outer wings might

otherwise be able contact each other in unusual

circumstances).

When unfolded, the latch pivots out and down

(disengaged). During fold, the outer wing folds ﬁrst, until

the stop posts contact each other. As the inner wing

then folds, and passes vertical, the latch swings into

engagement on the pins of the outer wing stop post.

At the start of unfold, the latches restrain the outer wings,

causing the inner wings to unfold ﬁrst. As the inner wings

near the ground, the latches fall away, allowing the outer

wings to unfold.

Solenoid Valves

See “Fold/Lift Circuit” on page 49 for functions

controlled by solenoid valves.
