NOTE! On models with HARDI PILOT the EC operating
unit is controlled via the HARDI PILOT - See separate
instruction book.
1. Choose the right nozzle size by turning the nozzle
bodies to a suitable nozzle for the spray purpose.
Make sure that all nozzles are the same type and size.
2. Open or close pressure agitation. (Remember pres-
sure agitation takes 5% to 10% of pump output).
3. Open main on/off valve 2 by pushing switch towards
green - spraying position A .
4. Open all distribution valves 4 by pushing switches V
to position Green. A green indicator appears under
the EC-motor when valve is in spray position.
5. Open pressure adjustment valve by activating switch
C until green finger screw 3 stops rotating.
6. Put the machine in neutral and set the engine revolu-
tions and thereby the number of revolutions of the
pump corresponding to the intended travelling speed.
Adjust the pressure adjustment valve
3 so that the
pressure gauge indicates the recommended pressure.
ADJUST THE PRESSURE EQUALIZATION SECTIONS
AS FOLLOWS:
8. Note the pressure and place the first of the distribution
valves 4 to position “off” (opposite “Green” position).
9. Turn the corresponding adjusting screw 1 until the
pressure gauge again shows the same pressure (turn
the screw clockwise for higher pressure, anticlock-
wise for lower pressure).
10.Place the next distribution valve to position “off”, and
adjust this one in the same way - one by one.
NOTE! HEREAFTER ADJUSTMENT OF PRESSURE
EQUALIZATION WILL ONLY BE NEEDED IF YOU
CHANGE TO NOZZLES WITH OTHER CAPACITIES.
OPERATING THE CONTROL UNIT WHILE DRIVING:
11.To close the entire boom, operate switch
A . This
takes the pressure from the pump. The liquid will then
return to the tank via the return system and serve as
agitation. The diaphragm anti-drip valves ensure in-
stantaneous closing of all nozzles. In order to close
part of the boom, activate one of the distribution
valves by the switch
V of the section or sections to be
closed. The pressure equalisation device ensures
that the pressure does not rise in the sections which
remain open.
Remote pressure gauge (if fitted)
The remote pressure gauge measures the working
pressure in the boom tubes as close to the nozzles as
possible. This pressure reading will always be slightly
lower than the reading at the operating unit pressure
gauge.
The outputs stated in the nozzle charts are always
based on the pressure measured at the nozzle.
Always adjust pressure when calibrating and spraying
according to readings at the remote pressure gauge.
Filling of chemicals.
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 in-
structions 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” and Blue valve towards “Agitation”.

3. Engage the pump and set engine revs. to 2200 r.p.m.
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.
