Adjustment of EVC operating unit
Before spraying, the EVC operating unit is adjusted using clean water
(without chemicals).
1. Choose the correct nozzle for the spray job by turning the TRIPLET
nozzle bodies. Make sure that all nozzles are the same type and
capacity. See the "Spray Technique" book.
2. On-off switch is activated against green.
3. All distribution valve switches are activated against green.
4. Pressure regulation switch is activated until emergency handle
stops rotating (minimum pressure).
5. Put the tractor in neutral and adjust the P.T.O. and thereby the
number of revolutions of the pump corresponding to the intended
travelling speed. Remember the number of revolutions on the P.T.O.
must be kept between 300-600 rpm (pump 540 r/min) or 650-1100
rpm (pump 1000 r/min).
6. Pressure regulation switch is activated until the required pressure
is shown on the pressure gauge.
Adjustment of pressure equalization
1. Close the first distribution valve switch.
2. Turn the adjusting screw(s) until the pressure gauge again shows
the same pressure.
3. Adjust the other sections of the distribution valve in the same
way.
ATTENTION! HEREAFTER ADJUSTMENT OF PRESSURE EQUALISATION WILL ONLY BE NEEDED WHEN:
1. YOU CHANGE TO NOZZLES WITH OTHER CAPACITIES
2. THE NOZZLE OUTPUT INCREASES AS THE NOZZLES WEAR
