Boom Breakaway Adjustment
The function of the breakaway is to prevent or reduce boom damage if
it should strike an object or the ground. If it is over-tight, it will not
function. If it is too loose, it will yawn (forward and back movement)
under spraying.
A. Lubricate coupling before adjusting spring tension.
B. First loosen counter nut, then slacken nut to adjust breakaway
resistance. Do not overtighten; better loose than over-tight. Minor
adjustments in the field may be necessary.
C. Ensure also channel bolts are tight.
Trapeze Suspension Adjustment
For the trapeze to function it must not be over-tight. If it is to loose the
boom will yaw. This results in a poor spray distribution.
Adjustment is made after having lubricated all pivot points (see section
on Lubrication).
A. Remove the lock pin for the trapeze suspension.
B. Adjust trapeze bolts so it is not too tight nor too loose.

ATTENTION! Again minor adjustment in the field may be
necessary.
