The condition of the nozzles is of critical importance in achieving an even spray distribution across the boom, and consequently a good deposit of the plant protection chemical. Carry out a visual check of the spray pattern of all nozzles when spraying clean water at normal working pressure. The spray pattern must be regular fan-shaped for normal flat fan spray nozzles. Irregularities are a sign of damage or wear.
Calibrate the flow rate of the nozzles with a measuring jug. The precision of the nozzles and distribution is acceptable with flow rates of up to 10% above the table values. If the flow rate is above 10% in excess of standard, the nozzles are worn and all nozzles should be replaced.
Remove the turn plate of the TRIPLET nozzle holder and lubricate with a little oil or grease on the plate. This will ensure the TRIPLET is always easy to turn when changing to another nozzle.
