Alternatively the same rate of 100 l ha could also be achieved with a larger nozzle and faster operating speed By referring to the TP nozzle chart on the previous page it can be seen that a TP8003 or TP1103 blue nozzle will give this rate at a little under 14 km hr and 3 0 Bar the rate shown on the chart at 14 km hr is 103 I ha Similarly an XR8003 XR11003 blue nozzle will also give 100 I ha at a little under 14 km hr and pressure of 3 0 Bar the rate shown on the chart below at 14 km hr is 101 I ha It can thus be seen that a variety of choices exist for most application rates and the final selection of nozzle speed and pressure will depend upon the factors which best suit your conditions Always perform a calibration check to confirm your nozzle selection as described on page 11 SPRAY NOZZLE SELECTION CHART FAN TIP LIQUID COLOUR amp FILTER PRESSURE CAPACITY morn 4 0 0 23 1 5 0 28 GREEN XR80015 XR110015 YELLOW XR8002 XR11002 46 56 APPLICATION RATE LITRES PER HECTARE 8 22 kmh kmh 28 20 34 38 55 41 50 58 71 82 55 67 T7 95 109 82 pasa CERES EEE Eee Do Bx eas TARARE EEE EEEE Ei gg 28a gs ee agaxsaeyagaase gales ynalyn Stuan Lubrication and Maintenance Daily Maintenance General During the first few days of operation before starting each day check that all hardware is tight and inspect the unit for leaks while running and tighten all hose clamps PTO Sh2.
