Boom lift.
The boom lift should be ad-
justed so the boom can freely
move up and down when the lift
cylinder is actuated. Do not
tighten so much that the lift
cannot work unhindered.
For MB boom - Adjust D so the
space E is about equal at all 4
points.
For HB boom - Loosen lock
nuts F and adjust bolts G.
Retighten lock nuts.
Trapeze suspension
For the trapeze to function it
must not be overtight. If it is too
loose the boom will yawn. This
results in a poor spray distribu-
tion.
Adjustment is made after
having lubricated all pivot and
friction points (see section on
Lubrication).
Adjust trapeze bolts H so it is
not to tight nor to loose. Minor
adjustment in the field may be
necessary.
Wire tension - HB boom only.
Slack wires result in excessive
boom yawn. To adjust, loosen
rigging screw lock nuts and
turn. If overtightened it will not
be possible to fold arm down.
