Re-adjustment of the Boom
After having used the sprayer for some days the boom should be
adjusted according to the following instructions.
NOTE:Tractor and sprayer must be on level ground.
Sprayer must be lubricated. (see section “Lubrication”).
WARNING
NOBODY MUST STAND UNDER THE BOOM WHILST ADJUST-
MENT IS TAKING PLACE.
Boom lift
The boom lift should
be adjusted so the
boom can freely
move up and down
when the lift ram is
actuated.
1. Unfold the boom.
2. Loosen counter
nuts K and adjust
the screws J so the
glide pads are just
touching at all
points in both
directions. Tighten
counter nuts.
Trapeze suspension
For the trapeze to function it must not be overtight. If it is to loose the
boom will yawn (forward and back movement). This results in a poor
spray distribution.
1. With the boom unfolded, check the tension on nuts M. They must
not be overtight.
2. The trapeze function is adjusted by tightening or loosening the 4
nuts N.
Minor adjustment in the field may be necessary.
