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)
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
=with the stirrer on a delivery, run the pump supplying the stirrer (or ejector) at the maximum pressure available for at least
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
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
- 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:
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.
