All filters should always be used, and their function
checked regularly. The mesh size of the filter in use
should always be smaller than the flow average of the
nozzles used. Therefore, pay attention to the correct
combination of filters, mesh size.

IMPORTANT!
The ball valve underneath the self-
cleaning filter should normally be open, but must be
closed in the following cases:
1. If rinsing with water from
the rinsing tank and a
quantity of spray liquid
still remains in the main
tank (otherwise the spray
liquid will be diluted).
2. If opening the self-
cleaning filter and a
quantity of spray liquid
still remains in the main
tank (otherwise there is a
risk that spray liquid will
flow out).
Choice of correct restrictor
It is important to have a large
flow through the filter. This is
achieved by choosing the
restrictor size in relation to the
liquid consumption of the spray
boom.
4 restrictors are supplied. Use the green
one (largest orifice) first.
The hose
N
is demounted at the self-clean-
ing filter, the restrictor is put in the hose and
the hose is mounted again. If the re-
quired working pressure cannot be
obtained, the restrictor is too large.
Choose a smaller restrictor. Start with a
black one, then a white and finally a red
one.

When cleaning the filter remove hose
N
and the hose at
the safety valve, and check there are no residues.
Standard filter size is 80 mesh. Sizes of 50 and 100
mesh are available and can be changed by opening the
filter top, and replace the strainer. Check the O-rings
before reassembling the filter and replace if damaged.

Chemicals can be filled in the tank in 2 ways:
1. Through tank lid.
2. By means of HARDI FILLER chemical filling device.
Filling through tank lid
The chemicals are filled through the tank lid - Note
instructions on the chemical container!
WARNING!
Be careful not to slip or splash
chemicals when carrying chemicals up to the
tank lid!
1.Make sure the EC on/off valve is switched off.
2.Set the MANIFOLD valves to correct position. Black
valve “Suction from main tank”, green valve towards
“Agitation”.
3.Engage the pump and set P.T.O. revs. to 540 r.p.m. or
1000 r.p.m. depending on pump model.
4.Add the chemicals through the main tank hole.
5.When the spray liquid is well mixed, turn handle on the
Pressure Manifold towards “Spraying” position. Keep
P.T.O. engaged so the spray liquid is continuously
agitated until it has been sprayed on the crop.
