WARNING! The folding functions (switches 5 and 6) must only be operated when the sprayer is stationary! Failure to
do so will damage the boom.
ATTENTION! The boom cannot be operated with the tractor’s hydraulic levers.
Single-sided folding (All HZ versions except Dual Fold)
It is possible to spray with only one side of the boom unfolded. If this is needed, first tilt down and unfold the boom
completely. Then push switch (5) or (6) inwards to fold in the left or right wing only. On the spray control unit also turn off
the spray sections placed on the folded side.
ATTENTION! It is not advisable to go directly from transport position to spray position with one side only. Both wings
must first be completely unfolded and then one side folded back in.
