Re-adjustment of the LHZ boom
Boom lift
The boom lift does not require any adjustments. Only
lubrication - see lubrication chart.
Trapeze suspension
For the trapeze to
function it must not be
overtight. If it is too
loose the boom will
yawn (forwards 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 func-
tion is adjusted by
tightening or loos-
ening the 4 nuts N.
Minor adjustment in the field might be necessary.

The boom and transport brackets are to be adjusted so
that boom movement is prevented when in transport.
1. Fold the outer sections and then the inner sections
until the folding rams are at maximum length and care-
fully place the boom in the transport brackets.
NOTE: The following is
best done without pres-
sure in the hydraulic rams.
2. Loosen counter nut C and
adjust the length of the rod F
until the boom fits in the trans-
port bracket.
