6.3 DOSAGE
Depending on the machine model, different types of dis-
penser can be installed. The available types are the following:
• Volumetric.
• Settable roller.
Dispensers can be used with small (e.g., rapeseed) or nor-
mal-sized seeds (wheat or barley) or fertilizer. The dispenser
should be set to the type of product and the quantity to be
dispensed.
IMPORTANT:
FOR NORMAL-SIZED SEEDS, THE
TURBINE AIR REGULATOR SHOULD BE SET TO
POSITION N (FIG. 6.20), AND FOR SMALL SIZES
WITH VERY SMALL QUANTITIES TO BE DOSED,
IT SHOULD BE IN POSITION F (FIG. 6.21). PER-
FORM FIELD TESTS BEFORE STARTING WORK.
CHECK THAT THE SEEDS ARE NOT BLOWN OUT
OF THE FURROW AND THAT THERE IS NO MATE-
RIAL BUILD-UP WHICH COULD CLOG THE COM-
PRESSED AIR SYSTEM.

TO CHANGE THE POSITION OF THE SEED OR
FERTILIZER DISPENSER FROM NORMAL TO FINE,
THE SPINDLE (FIG. 6.23) MUST BE ABLE TO TURN
AND THE HOPPER MUST BE EMPTY.
In order to change the position of the locking ring to posi-
tion N or F, the dispenser must be completely closed (posi-
tion 0) and there must be no material inside it. If the hopper
and dispenser are full of product, proceed as follows:
1-
Close the guillotine door (Fig. 6.24).
2-
Open the Venturi injector cover by lifting the two quick-re-
lease fasteners and moving the calibration control to the
"NO" position (Fig. 6.25).
3-
Place the bag supplied or a container under the Venturi
injector outlet (Fig. 6.26).
4-
Rotate the machine transmission a few turns to empty the
product from the dispenser (Fig. 6.27).
5-
Lastly, close the Venturi injector cover, move the calibra-
tion control to the "OK" position and lock it.
