Operation of trapeze
The trapeze suspension must be correctly adjusted and regularly
lubricated, if it is going to operate satisfactorily.
The primary function of the suspension is to protect the boom against
vibrations and shocks. It also helps maintain it a uniform height above
the target.
For MB boom - Under normal
field operation, remove trapeze
lock pin C. Replace pin to block
function, for example before
folding the boom or when
spraying on sloping terrain.
For HB boom - Under normal conditions the trapeze is always active.
When spraying on flat fields, use pos. 2. On sloping terrain the boom
can be slanted (pos. 1 or 3) and still maintain an active trapeze.

Pulsation damper (if fitted)
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.
