4.13 WASHING THE SPRAYER
Thoroughly wash the machine after each treatment pumping clean water
through the circuit and clean the suction and delivery filters.
Warning: Dirty equipment is very dangerous for the people and environment.
Discharging the residues of washing in the environment without taking
precautions is forbidden as this pollutes watercourses. Distribute the residues
on the treated field.
WARNING: The tank washing is controlled by tap N. 1, premix N. 2 and stirrer
N. 3.
4.13.1 CIRCUIT WASHER AND TANK WASHER
CAMPO machines can be equipped with with a circuit washer tank (FIG.11).
This tank must be filled with clean water and used to rinse the entire circuit
including the suction, delivery, pump, pressure regulator, jets and nozzles.
Thanks to the practical rotary nozzle it also rinses the inside surfaces of the
tank.
NB: To completely clean the tank and the pipes of any residues of the various
active principles, we recommend adding 2kg of soda to the washing liquid for
every 100 L of water.
At the end of the treatment, wash the circuit and the tank.
a) Stop the diaphragm pump disengaging the power-takeoff.
b) Check you have filled the circuit washer tank (C).
c) Make sure the main control of the pressure regulator is OFF and that all
the boom sectors are closed.
d) Turn suction deviator A to the circuit washer position (H2O).
e) Start the diaphragm pump by engaging the power-takeoff.
f) Increase the engine speed until all of the liquid in circuit washer tank C has
been sucked up.
g) Turn the diaphragm pump off and turn deviator A to the work position
(TANK).
h) Turn the main control to ON, so there is pressure in the circuit.
i) Start the diaphragm pump again and use the tank washing tap (BLUE) on
the regulator (or on pump) that supplies jet B.
j) After a few minutes you can close the tank washing tap
k) Distribute the washing residues over a portion of the field where it won’t
cause damage.
l) After you have finished washing, stop the diaphragm pump.
NB: at the end of the washing cycle, if there is the risk of frost, pour roughly
500 grams of normal antifreeze for auto vehicles into the tank.
4.13.2 WASHING WITH FULL TANK (OPTIONAL)
CAMPO machines can be equipped with a discharge deviator that makes it
possible to wash the pump and circuit even with a full tank.
a) Stop the diaphragm pump by disengaging the power-takeoff.
b) Check that you have filled the circuit washing tank (C).
c) Check that the main control of the pressure regulator is OFF and that all
the boom sectors are closed.
d1) Turn discharge deviator S to the WASH position
d) Turn suction deviator A to the circuit washer position (H2O).
e) Start the diaphragm pump by engaging the power-takeoff.
f1) Increase the engine speed until all of the liquid in circuit washer tank C
has been sucked up.
g) After 1-2 minutes, turn the main control to ON, so there is pressure in the
circuit.
i) Open the section taps to spray the liquid in circuit washer tank C.
k) Distribute the washing residue over a portion of the field where it will not
cause damage.
l) After you have finished washing, stop the diaphragm pump.
NOTE: Before using the machine again for spraying, turn taps A and S back
to the correct operating position
