down the IN end of the 'Boom Fold' rocker
switch. The boom will fully rise, tilt & fold-in
over the boom rests.

Lower' push button on the Joystick to lower
the boom until it stops at its preset height.
The main boom lift suspension accumulator
will then automatically lock out.
When folding the boom, either manually or automatically,
ensure the sprayer chassis is laterally level.
If the chassis is sloping laterally, sprayer stability and boom
folding can be compromised.

8 Boom Centre Levelling

The Boom Centre Levelling system keeps
the boom in the same plane as the machine
so that the boom folds evenly.
If one side is heavier than the other, the
boom will tend to hang lower on the heavy
side, therefore, both sides need to be
levelled to maintain boom ends at the same
height.
If the centre and the booms tilt excessively
during folding, the centre level cables may
need to be adjusted. With time & use,
cables stretch and will require adjustment.
Cable tension can be adjusted by tightening
or loosening the nuts on the end of the cable
bolts on either side.
