• The operator must:
a.
Shake the mixture in the tank before starting the treatment, re-circulating it completely for as long
as it takes to make it homogeneous.
b. Check the orientation of the distributors (hands, guns and/or fishtails) of the distribu-
tion device (sprayhead) in relation to the dimensions, the shape and the thickness
of the vegetation to be treated.
c. Continue to shake the mixture until the treatment is resumed should the intervention momentarily
be interrupted. If the utilisation is to be deferred, check that the filter cartridge is clean before
resuming and agitate the mixture that has remained in the tank.
d. Ensure that the hand wash supplementary tank is filled with clean water after each filling operation.
e. Make use of individual protections identical to those envisaged for the preparation of mixtures if
the tractor is not equipped with a pressurised cabin with aeration filters.
f. wash immediately all the elements that might have become contaminated during the treatment,
promptly remove the polluted garments and interrupt the work if these cannot be
immediately replaced.g. Keep to the preliminary operations already indicated (10.1.c),
in case of wind conditions prevailing.
h. Stop the engine, remove the key from the tractor’s control panel and lower the hoist during
stoppages.
i. Pay particular attention to the treatment when close to boundaries and in proximity of dwellings,
waterways, roads or public-usage paths.
10.4 - PROCEDURE TO WASH THE HYDRAULIC CIRCUIT
(head-pump)
In case of machines equipped with unit-washing tank, every time it is necessary
to suspend the treatment, it is possible to carry out the hydraulic circuit washing
process, independently on the loading conditions, i.e., also when the tank is still
containing some product mixture, so avoiding any possible clogging and assuring
the perfect efficiency of the machine when the treatment is carried on again.
In case of prolonged idle periods, it is recommended to keep the mixture agitated
(see Chapter 9).
In order to carry out the hydraulic circuit washing process, follow the instructions here specified:
a. Close the faucet (P3) of exclusion of the additional agitation.
b. Close the pressure regulator completely, by rotating the hand regulator (P5) handle clockwise or
by turning the pressure up (keep the joystick on “+” for about 15 seconds) for the E.P.A. versions.
c. Open the cock (P15), by setting it to position “b”; in that way the clean water contained inside the
unit-washing tank is sucked by the pump (P4) and gets into the hydraulic circuit.
