OPERATION AND ADJUSTMENTS
10- Repeat this operation twice and take the average, adding time 1 and time 2 and dividing by
two (e.g.: time 1 = 29s; time 2 = 31s; 29 + 31 = 60s; 60 ÷ 2 = 30s average, that is the time it takes
to spray the distance previously obtained in "item 4", which is 50m).
11- Stop the tractor with the rotation used to travel the 50 m, run the sprayer, pull the trigger (lance
LP-1130) or turn the knob on (gun) to begin the spraying and adjust the pressure according to the
recommendation for the nozzle type:
- Cone nozzles: from 45 to 200 psi
- Flat fan nozzles: from 15 to 60 psi
- Deflector nozzles: from 15 to 30 psi
- Stainless steel nozzles series D: from 100 to 400 psi
12- Collect the spraying volume in a container during the time determined (e.g.: 30s according to
"item 9").
13- Measure the spraying volume in a graduated bottle.
14- Repeat this operation twice and take the average (e.g.: 5 liters)
15- To determine the spraying volume in 1 hectare, multiply 100 by the volume sprayed in 100 m²
(e.g.: sprayed volume = 5 liters x 100 = 500 L/ha spraying volume).
16- Contact an agronomist and read the product instructions to check if the volume is inside the
recommended limits. If the volume varies 10% from the recommended volume, proceed as follows:
1- If the spraying volume is below that desired, increase the pressure, decrease the speed (but
keep 540 rpm at PTO) or change the nozzles for others of higher flow rate.
2- If the spraying volume is above that desired, decrease the pressure, increase the speed (but
keep 540 rpm at PTO) or change the nozzles for others of lower flow rate.
If it is necessary to carry out any of the above procedures, repeat the calibration procedure.
• When the recommended product dosage is concentrated (e.g.: 150 ml/100 L water), check the
proper spraying volume through the beginning of the chemical flow, in case of foliage, or the desired
droplet concentration.
17- Contact an agronomist and read the product instructions to identify the recommended
dosage.
• If the dosage is recommended in hectare (e.g.: 2.5 L/ha), calculate the necessary quantity of
product for each filling operation in relation to the sprayed volume. For example, if the tank capacity
is 400 liters and the spraying volume is 500 L/ha, the necessary quantity of product is (400 ÷ 500)
x 2.5 = 2.0 liters product per tank.
• If the dosage is recommended in concentration (e.g.: 150 ml/100 L water), calculate the necessary
quantity of product for each filling operation in relation to the tank capacity. For example, if the tank
capacity is 400 liters, the necessary quantity of product is (400 ÷ 100) x 150 = 600 ml product per
tank.
