15.6 CHECK HYDRAULIC DELIVERY
THE CHECK IS CONSIDERED TO BE SUCCESSFUL (THE MACHINE IS PROPERLY CALIBRA-
TED) WHEN THE CALCULATED VALUE “Q” CORRESPONDS TO THE VALUE INDICATED
ON THE “FLOW CHART” TABLE WITH A ±2.5% TOLERANCE.
If the resulting values are different, check the efficiency of the pipes, the fittings, the pressure gauge
and the correct positioning of the calibration discs (P11). If necessary, replace the damaged or defective
parts and repeat the test.
15.6.1 Check whit flowmeter
1. Disengage the fan (for versions where it is foreseen): see Paragraph 8.1.a.
2. Fill the tank with enough clean water to make the test.
3. Turn the 3-way valve (P6) to “
D ”position (Maintenance).
4. Disconnect the pipe (T4) from the electrical distributor (E9) or from manual distributor (P9).
5. Connect the appropriate flowmeter for the measurements to be made, between the pipe (T4) and
the electrical distributor (E9) or the manual distributor (P9). If necessary, remove the fitting (P26)
and use the fittings suitable for connecting the flowmeter.

6. Turn the 3-way valve (P6) to “ A ” position (work)(Work - phytosanitary products distribution).
7. Engage the fan (for versions where it is foreseen): see Paragraph 8.1.b..
The declared performance is achieved with the PtO at 540 rpm and with the fan
running. For a correct result of the check, this condition MUST ALWAYS BE
RESPECTED.
8. Run the PtO at 540 rpm.
9. Open the taps of the 2-way distributor:
a. if electric (E10), set the switches to “ON”
b. if manual (P9) turn the levers vertically
10.Adjust the working pressure by using the manual pressure regulator (P5) (or the electric one E5)
and the position of the calibration disc (P11) according to indications given on the “flow charts” for
the distribution device (sprayhead) used.
11. Take the flow rate per hour.
