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)

4.12.1 MANUAL 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.).

4.12.2 PREMIXER 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.

(116 psi)

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: 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.
