6 - Maintenance
Adjusting Rear Cable
1. Raise the 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 this, if necessary.
3. Loosen the counternuts (E) on the ends of turnbuckle (F). Adjust
the turnbuckle (F) so that the outer wing contacts the boom
transport bracket.
4. When adjusted, the turnbuckle needs to be further tightened:
Boom size
Tightening
18-21 m
Turn the turnbuckle another 4 complete turns.
24-28 m
Turn the turnbuckle another 3 complete turns.
5. Secure the counternuts (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 Centre Section Cables
The centre section cables keep the centre frame in correct position
during the folding procedure or when spraying with one side raised and
folded (SPB-Z only).
1. Fold the boom into transport position.
2. Check that the tilt cylinders are completely extended. Adjust if
necessary (SPB-Z only).
3. Check that the centre section cable (A) is routed over the centre
section nozzle bracket (B).
4. Loosen the counternuts 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 110 mm. Properly
adjusted cables will be very tight and only deflect very little (few
millimetres) when pulled by hand.
÷
NOTE! The cables will be loose when the boom is unfolded.
6. Tighten the counternuts on the bolt assembly (C) again.
7. Unfold the boom and inspect that the centre frame is correctly centred.
μ
ATTENTION! Adjust both boom wings in one sequence. Only slightly adjust the cables, and adjust one cable at a time,
to equalize cable tension and maintain a level centre frame.
±
WARNING! Never adjust the centre section cables without having folded the boom all the way into the transport
position.
