5.1 Precautions
When installing the foam marker it is necessary to observe a few essential rules:•When fixed, the compressor unit should be sheltered from sprayed products or stones which
can be thrown by tractor wheels.•On seeders, install the electric-compressor unit sheltered from areas that are too dusty.•Install the foam marker at bar ends using the supplied supports at a distance from the last
spraying nozzle equal to half the distance of one nozzle to the other (Fig. 3). •The foam must fall in an area sheltered from the nozzle and the point where it falls must mark
the area treated by the boom.•Fix the pipes of the pneumo-hydraulic system to the framework with clamps, in a position pro-
tected from possible impact with the ground or with the boom framework.
•At the joints of the booms the pipes must be of such a length as to allow the booms to open and close without damaging the pipes.
•Place the tank upright with the cap easily acces-sible for filling and adjusting the flow rate.
•Apply the tank so as to make it possible to be removed for periodical washing.
•The compressor cover should be easily removed for maintenance operations.
