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.
Outersection (8m SB)
The hindge should be firm.
If overtight it is difficult to fold.
To adjust, tighten or loosen nuts C.
