Before spraying, the EVC operating unit is adjusted
using clean water (without chemicals).
1. Choose the correct nozzle for the spray job by turning
the TRIPLET nozzle bodies. Make sure that all
nozzles are the same type and capacity. See the
“Spray Technique” book.
2. On-off switch
A
is activated against green.
3. All distribution valve switches
V
are activated against
green.
4. Pressure regulation switch
C
is activated until emer-
gency handle stops rotating (minimum pressure).
5. Put the tractor in neutral and adjust the P.T.O. and
thereby the number of revolutions of the pump
corresponding to the intended travelling speed.
Remember the number of revolutions on the P.T.O.
must be kept between 300-600 rpm (pump 540 r/min)
or 650-1100 rpm (pump 1000 r/min).
6. Pressure regulation switch
C
is activated until the
required pressure is shown on the pressure gauge.
Adjustment of pressure equalisation
1. Close the first distribution valve switch
V
.
2. Turn the adjusting screw(s) until the pressure gauge
again shows the same pressure.
3. Adjust the other sections of the distribution valve in
the same way.

1. Choose the correct nozzle. Make sure that all nozzles
are the same type and capacity. See “Spray Tech-
nique” book.
2. Open or close lever
1
depending on whether pressure
agitation is required. (Remember pressure agitation
takes 5% to 10% of pump output).
3. Turn main ON/OFF handle
2
to ON position
A
.
4. Set all hand levers
3
on the distribution valve to ON
position
A
.
5. Turn the HARDI-MATIC valve
4
anti-clockwise to its
extreme position.
6. Put the tractor in neutral and adjust the P.T.O. thereby
the number of revolutions of the pump corresponding
to the intended travelling speed.
NOTE!
The P.T.O. revolutions must be kept between
300-600 r/min.
7. Adjust the HARDI-MATIC valve
4
so that the pressure
gauge indicates the recommended pressure.
ADJUSTMENT OF PRESSURE EQUALIZATION:
8. Place the first lever
3
on the distribution valve in OFF
position
B
.
9. Turn the adjusting screw
5
until the pressure gauge
again shows the same pressure.
10.Adjust the other sections of the distribution valve in
the same way.
Hereafter adjustment of pressure equalization will
only be needed if you change to nozzles of other
capacities.
11.Operating the control unit while driving:
To stop the liquid flow to the boom turn the ON/OFF
handle
2
to OFF position
B
. This returns the pump
output to the tank through the return system. The
diaphragm anti-drip valves ensure instantaneous
closing of all nozzles. To stop the liquid flow to one or
T020-0019
more boom sections, turn lever
3
of the distribution
valve to OFF position
B
for the section to be closed.
The pressure equalization ensures that the pressure
does not rise in the sections which are to remain
open.
