Adjusting Center Section Cables; Jaw Rubber Dampers (Spc Only) - Hardi NAVIGATOR 3000 Instruction Book

6 - Maintenance

Adjusting center section cables

The center section cables keep the center frame in correct position
during folding procedure or when spraying with one side raised and
folded (SPB-HZ only).
1. Fold the boom into transport position.
2. Check that the tilt cylinders are completely extended. Adjust if
necessary (SPB-HZ only).
3. Check that center section cable (A) is routed over center section
nozzle bracket (B).
4. Loosen jam nuts on the bolt assembly (C). This applies to both
boom wings.
5. Adjust the threaded bolt(s) (C). Alternate from side-to-side while
making adjustments. As a guideline for adjustment, the distance
(D) shown at the bolt assembly should be 4-5/16" (110 mm).
Properly adjusted cables will be very tight and only deflect a small
amount (fractions of an inch) when pulled by hand. Note that
cables will be loose when the boom is unfolded.
6. Tighten jam nuts on the bolt assembly (C) again.
7. Unfold the boom and inspect that the center frame is correctly
centered.
ATTENTION! Adjust both boom wings in one sequence. Adjust one cable a small amount at the time, and then the
other cable, to equalize cable tension and maintain a level center frame.
±
WARNING! Never adjust the center cables without having folded the boom all the way into the transport position.

Jaw rubber dampers (SPC only)

Inspect basic adjustment of the rubber jaw dampers. Basic adjustment
= The compression of the jaw (C) should correspond to a distance (E) of
1-11/32" (34 mm). Measure and adjust the jaw if necessary by means of
the two M12 bolts (A).
The channel section (B) is a part of the center section frame, and jaw (C)
is held by the plate (D).
