5 - Operation
• Spraying:
On the sprayer, turn the suction SmartValve towards "suction from
main tank" and the pressure SmartValve towards "spraying". Turn
the agitation valve to "agitation" if needed.
• Shut all nozzles:
Set the main spray ON/OFF (11) to OFF position. This returns the
pump output to the tank through the return system. The
diaphragm non-drip valves ensure instantaneous closing of all
nozzles.
• Close one or more sections of the boom:
Switch the relevant distribution valve (16) to off position
(upwards). The DF4 pressure equalization ensures that the
pressure does not rise in the sections, which remain open.
Filling/Washing Location Requirements
When filling the sprayer with chemicals and water, it is important to avoid spot contamination by spraying chemicals in
order to protect the subsoil water resources.
Dedicated Filling Site
If the sprayer is always filled on the same location, a special filling/washing location should be established. This should have
a hard, liquid-impenetrable surface (e.g. concrete) securing against seepage, together with edges securing against run-off
to the surrounding areas. The location should be drained to an adequate receptacle (e.g. slurry tank or similar).
Any spillage or washings should be retained and diluted in order to be distributed in a larger area. This is to ensure minimal
environmental impact and avoid build-up of larger chemical concentrations at one spot.
If no other requirements of distances exist, the following general recommendation of distance can be used. Filling location
must be no closer than:
1. 50 metres from public water supplies for drinking purposes.
2. 25 metres from non-public water supplies for drinking purposes and from treatment sumps and cesspools of drainage
systems.
3. 50 metres from surface water (watercourses, lakes and coastal waters) and from nature reserves.
In the Field
Alternatively the sprayer can be filled in the field, where the spraying is to take place. If so, choose a different location for
each refilling.
If no other requirements of distances exist, the filling should not take place closer than:
1. 300 metres from public or non-public water supplies for drinking purposes.
2. 50 metres from surface water (watercourses, lakes and coastal waters), treatment sumps, cesspools of drainage
systems, and nature reserves.

ATTENTION! Legislation and requirements vary from country to country. Always follow local legislation in force.

ATTENTION! It is the responsibility of the sprayer owner/operator to comply with all relevant legislation. HARDI cannot
