4.12 MIXING
The active principle can be mixed using the relevant stirrers before and during
the treatment. Correct mixing and stirring is the basis of the correct distribution
on the crops. We recommend some useful accessories such as the premixer
for powders and liquids (see the following paragraph).
To mix the product in the tank proceed as follows:
a) high-pressure machines from 30 to 60 bar (FIG. N° 13): run the stirrer (or
ejector) for roughly 10-15 minutes at the maximum pressure available
b) low pressure machines, max 20 bar
= with a drilled pipe on the drain, run the pump at roughly 540 RPM with the
pressure regulator on drain for at least 10-15 minutes. (FIG. N° 14)
= with the stirrer on a delivery, run the pump supplying the stirrer (or ejector)
at the maximum pressure available for at least 10-15 minutes. (FIG. N° 13)
Some models with very small tanks aren’t equipped with mixers, you should
use the drain of the pressure regulator: run the pump at roughly 540 RPM with
the pressure regulator in the drain position for at least 10-15 minutes. (FIG. N°
15)
4.12.1MANUAL PREMIXING
Dilute the active principle by hand before introducing it into the tank, (you must
wear suitable protective clothing such as rubber gloves, a mask or goggles,
overalls, etc.).
4.12.2PREMIXER ON COVER (OPTIONAL):
Open the cover and pour all of the chemical powder into the filter, close the
cover and open the supply tap until all of the powder has dissolved.
4.12.3PREMIXER ON HOPPER WITH TIN WASHER
(LASER - FUTURA P16-P20 series) (see Fig. N° 16)
- After having freed hook “g”, extract the premixer and lift cover D.
- Open supply tap A on the pump so the liquid flows at a maximum pressure of
8 bar, then open gate B to the tank.
- Introduce the product to mix and, after you have closed cover D again, press
grip C to mix the product in the hopper, watching the level of the liquid to make
sure it doesn’t overflow.
(To prevent overflowing and to help powder products dissolve, always keep gate
B) open.
To wash the tin, proceed as follows:
-Lift cover D
-Open tap A supplying it with a pressure of at least 8 bar
-Introduce the tin into the hopper inserting washing pipe E into the tin.
-Press the same tin onto the pipe until it has been completely washed.
-Drain the liquid into the tank by opening gate B.
-If the tin washer isn’t supplied with clean water and isn’t fitted with the optional
electrical pump, you must rinse again with clean water by hand.
THE LIQUIDS USED FOR RINSING SHOULD BE INTRODUCED INTO THE
TANK TO BE SPRAYED ON THE FIELD.
At the end of the operations, close gate B then close tap A, insert the premixer
in the housing again, blocking hook “g”.

WARNING:
don’t open the gate if the
ejector isn’t functioning.
WARNING: using the taps on the pump or in any
case on the front of the machine puts the operator
near the cardan shaft. Despite the presence of
CE standard protective covers you should take
great care.
