Checking the Boom Hinge
Springs
No Parts Required
Procedure
Important: Operating the spray system with the boom
hinge springs under the incorrect compression could
damage the boom assembly. Measure the springs and
use the jam nut to compress the springs to 3.96 cm (1.56
inches), if necessary.
The sprayer is shipped with the boom extensions swung
forward to facilitate packaging of the machine. The springs
are not fully tightened at the time of manufacture to allow the
booms to be in this position for transit. Before operating the
machine, adjust the springs to the correct compression.
1. If necessary, remove the packing components that
secure the right and left extension booms during
shipping.
2. Support the booms while they are extended to the
spray position.
3. At the boom hinge, measure the compression of the
upper and lower springs while the booms are in their
extended position (Figure 1).
A. Compress all springs until they measure 3.96 cm
(1.56 inches).
B. Use the jam nut to compress any spring that
measure greater than 3.96 cm (1.56 inches).
