Operating instructions
Operation of the boom
Remove boom transport lock pin (8 metre
only). When unfolding (or folding) the initial
force to release the spring loaded breaka-
ways will be higher than the actual unfold-
ing/folding.
CAUTION: The breakaways must be
correctly tensioned and lubricated. (see
section on Re-adjustment of the boom)
Replace boom transport lock pin when
driving with folded boom.
Boom height
Correct boom height is very important in order to achieve the most
optimal spray pattern. (See Spray Technique book).
Small adjustments of the boom height can usually be made with the 3-
point suspension from the tractor - raising or lowering the sprayer.
In crops where greater adjustments are needed the boom height can
be changed manually by removing the 4 bolts holding the boom to the
frame.
Note: This is best done by 2 persons or with a mechanical hoist.
Pulsation damper
The air pressure in the pulsation damper is
preset at the factory to 2 bar. This covers spray
working pressures between 3 and 15 bar. When
using spray pressures outside this range, the air
pressure should be adjusted as shown in the
diagram. The diagram is also embossed on the
damper.
