USE OF THE MACHINE
After checking the type of nozzles suitable for the spray rate required and the calibration of all the parts of
the machine, follow this procedure to perform chemicals application.
6.1
TANK FILLING
Main chemicals tank filling is possible only with machine stopped, parked on a flat area and protected
against possible mixture leaks to avoid potential contaminations.
Standard way of filling is using the low fill-up points. These fill-up points are equipped with fast plugs.
You must connect a flexible hose to the fast plug; the piping must be in pressure to let the water arrive to the
top of the tank.
Fast plugs for main chemicals tank and flush tank are not designed to suck water.
You must provide a pressure line to fill up the tank.
On the fill up line for the tank maximum pressure allowed is 8 bar | 116 PSI.
Do NOT overtake this pressure limit to avoid damages to fittings and hoses.
To fill the tank you can also use the lids placed on the top left part of the tank and preferably the lid without
pre-mixer.
Fill the tank with clean water, sediments free, to avoid the obstruction of the filters.
Fill the tank to the level suitable for the application requested.
Never fill the tank completely, leave always a free space for possible foam or water movements.
Remember to fill up the hand washing tank and the flush tank with clean water.
6.2
SPRAY PUMP ENGAGEMENT
Before starting the spray pump for spraying operations, make sure the 3-way valve is correctly set-
up to let the pump suck from the main chemicals tank.
Set the engine speed to minimum revs. Engage the pump by the switch
.
The engagement of the electric clutches is possible only if the engine revs are lower than 1200 rpm.
With manual controls, use the switch
to reduce pressure to minimum.
With automatic controller, switch to manual mode and use button
to reduce pressure to minimum.
Set the diesel speed to about 1300 rpm, let the pump run for some seconds to help priming.
After some seconds of pump running, make sure there are no more air bubbles in suction hoses
(between tank and suction filter and between suction filter and pump).
Do NOT start spraying operations if there are still air bubbles in suction hoses. These air bubbles
mean that the pump is sucking air. Check the suction filter, its ORing, make sure all suction hoses
are correctly tightened and secured to the fittings.
