Re-adjustment of the boom
After having used the sprayer for some days the boom should be
adjusted as follows:
When adjusting the sprayer must be on level ground with unfolded
boom. For MB booms - Remove the lock pin for trapeze.
C
Boom breakaway
The function of the breaka-
way is to prevent or reduce
boom damage if it should
strike an object or the ground.
If it is overtight, it will not
function. If it is too loose, it
will yawn (forward and back
movement) under spraying.
Lubricate coupling before
adjusting spring tension.
Slacken screw nut A to
decrease breakaway resist-
ance. Do not overtighten;
better to loose than overtight.
Again minor adjustments in
the field may be necessary.
For MB boom - Ensure also
channel bolts B are tight.
Outer section
The hinge should be firm. If
overtight it is difficult to fold.
To adjust, tighten or loosen
nuts C.
