UPON COMPLETING THE FLOW TESTS, CLOSE
THE VENTURI INJECTOR COVER, MOVE THE
CALIBRATION CONTROL TO THE "
OK
" POSI-
TION AND LOCK IT (Fig. 6.59).
UPON COMPLETING THE FLOW TESTS, IF THE
MACHINE HAS THE MICROGRANULATE OR
CONVENTIONAL FERTILIZER KITS, RECONNECT
THE PIPES TO THE COLLECTION BOXES
VERY IMPORTANT:
UPON COMPLETING THE
FLOW TESTS, REINSERT THE TRANSMISSIONS'
"R" PINS.
THE TURNS MUST BE MADE AT A CONSTANT
SPEED, APPROXIMATELY ONE TURN PER SEC-
OND. THE NUMBER OF TURNS IS APPROXIMATE
AND MAY VARY DEPENDING ON THE SOIL, THE
TYRE MANUFACTURER OR THE WHEEL PRES-
SURE. ACCORDINGLY, IT IS RECOMMENDED TO
PERFORM A FIELD TEST (SEE SECTION 6.6 FIELD
TEST FOR DOSAGE).
IMPORTANT:
IN DOSAGES THAT ARE CLOSE
TO TOTAL PRODUCT QUANTITIES OF 450 kg/ha
(TAKE INTO ACCOUNT SEED, FERTILIZER AND
MICROGRANULATE), CHECK THAT THERE IS
NO MATERIAL BUILD-UP CLOGGING THE COM-
PRESSED AIR SYSTEM. IF THERE IS, REDUCE THE
DOSE.
IMPORTANT:
AFTER COMPLETING THE FIRST
HECTARE OF WORK, CHECK THAT PRODUCT
CONSUMPTION IS AT THE DESIRED LEVEL.
