Adjusting Rear Cable; Adjusting Center Section Cables; Shock Absorbers - Hardi Ranger 550 Instruction Book

Adjusting rear cable

1. Raise boom to its highest position. Fold it to transport position
with tilt cylinders fully extended. Make sure that fold cylinders are
pressurized and that the boom is folded all the way in.
2. Ensure the boom transport brackets are in contact with the outer
wing. Adjust if necessary.
3. Loosen the jam nuts (E) on the ends of turnbuckle (F). Adjust the
turnbuckle (F) so that the outer section contacts the boom
transport bracket.
Turn the turnbuckle another 4 complete turns.
4. Secure jam nuts (E) again.
±
WARNING! The rear cable can snap and injure you or someone else if tensioned when the boom is unfolded. Always
adjust the front cable first - with the boom unfolded and the rear cable last - with the boom folded in transport
position.

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-HV/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 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.

Shock absorbers

If the shock absorbers loose their efficiency or start leaking oil, they should be replaced.
