Filters
Filters on your sprayer are there to protect the components and prevent nozzle clogging.
An EasyClean suction filter is fitted in the working zone.
A Cyclone pressure filter is fitted on the sprayer’s right side just in front of the hose reel, hidden behind the right front cover.
It has a built-in self-cleaning function.
In-line pressure filters can be fitted at each boom section.
Nozzle filters are fitted at each nozzle (optional).
A coarse filter basket is located below the main tank lid.
˜
ATTENTION! All filters should always be in use and their function should be checked regularly. Pay attention to the
correct combination of filter and mesh size. For more, see “Filters” on page 152.
˜
ATTENTION! Always run your sprayer with clean filters to ensure proper functions and to protect the interior of the
pump and valves.
EasyClean Filter
This filter collects impurities when liquid is being sucked out of the main
tank by the main pump.
To ensure proper function of the filter and its built-in valve, the filter
must be opened at least once every month. A label on the lid also
designates this.
A clogging indicator is located beside the spray pressure gauge on the
platform. This works as a vacuum gauge for the filter during operation -
the pointer moves from green towards red, if the filter starts clogging.
