Hydraulic Breakaway Circuit
90 and 100-ft. spray booms are equipped
with a Hydraulic Breakaway Circuit. When
folded out as an 80, 90, or 100-ft. spray
boom, a one-way hydraulic circuit (located on
the outer boom section) provides outer boom
breakaway functions.
When the outer boom section breaks
away, it will return to the “spray” position
(after it has cleared the hazard), but will not
be in the locked position.
To Reset the Outer Boom Breakaway:
•
Press and hold the Reset Breakaways
Button (Located on the Machine Display
Auxiliary Controls Page) until the outer
boom sections are in the LOCKED posi-
tion.
NOTE: On 90-ft. spray booms, the main
breakaways cannot be folded unless
machine speed is less than 5 mph
(8 km/h).
