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.
Boom breakaway
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.
Lubricate coupling before
adjusting spring tension. Slacken screw nut A to decrease breakaway
resistance. Do not overtighten; better to loose than over-tight. Again minor
adjustments in the field may be necessary.
Ensure also channel bolts B are tight.
Outer section (8m boom)
The hinge should be firm. If
overtight it is difficult to fold. To
adjust, tighten or loosen nuts C.
