A EasyClean suction filter is fitted in the working zone.
A Cyclone pressure filter is fitted to the sprayers right side just in front of the ChemLocker (optional equipment). It has a built-
in self-cleaning function.
In-line pressure filters can be fitted at each boom section as an option.
Nozzle filters are fitted at each nozzle.
All filters should always be in use and their function checked regularly. Pay attention to the correct combination of filter and
mesh size (see “Spray Technique” book).
