Adjusting centre section cables
The centre section cables keep the centre frame in correct position
during 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 centre section cable (A) is routed over centre section
nozzle bracket (B).
4.
Loosen counternuts 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 110 mm. Properly
adjusted cables will be very tight and only deflect a small amount
(mm) when pulled by hand.
÷
NOTE! Cables will be loose when the boom is unfolded.
6.
Tighten 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. Adjust one cable a small amount at the time, and then the
other cable, to equalize cable tension and maintain a level centre frame.
±
WARNING! Never adjust the centre cables without having folded the boom all the way into the transport position.
Check/adjust sprocket timing (SPB only)
1.
Unfold the boom and stand on its rear side.
2.
Check that the pin connection (A) in the timing chain is aligned
with the centreline (B) between the sprocket. Note forward driving
direction (C) - adjustment is done at rearside of the boom. (A) is the
7th pin connection on the chain.
3.
To adjust timing, loosen turnbuckles on the front and rear cables
until slack.
4.
Line up the chain and sprocket as indicated in step 2 above.
