Calibration Of Manual Knapsack Sprayer; Choosing Nozzle Type - Jacto XP Serie Manuel Du Operateur

Spray downwind and avoid drift Keep constant height

4.2. Calibration of manual knapsack sprayer

Using calibrator bottle (optional).
• Hold the lance at the working height and spray to measure
the application band width.
• Based on the band width, calculate the total walking distance
required to spray the desired area. Use the chart below.

Record the time it takes to Simulate the spraying of 25 m²
walk 25 m²
1. Remove the cap, nozzle and filter.
2. Mount the calibrator cover to the lance.
3. Reinstall the filter, nozzle and cap.
4. Screw the calibrator onto the cover.
• Hold the lance at the normal working height and spray into
the bottle while walking the distance required to spray an
area corresponding to 25 m².
• Place the bottle on a level surface and observe the liquid level
visible through the side of the bottle. Match the liquid level to
the corresponding scale on the calibrator bottle.
• Empty the bottle and repeat this operation to determine the
average of two or more readings.
NOTE: For the volume in liters per bushel (L / alk), simply multiply
the value obtained in liters per hectare (L / ha) by 2.42.

nance and parts replacement.

4.3. Choosing nozzle type

Seven main nozzle designs are used on knapsack sprayers. Each
nozzle design is available in a range of sizes to optimize the use
of product to be applied. The nozzle choice will be based on the
agrochemical type to be used and the droplet size recommend-
ed (table):
NOTE: This sprayer is packaged with Blue Adjustable Cone noz-
zle fitted in the lance. Other nozzles mentioned in this manual
are optional, so they do not accompany this sprayer.

Prevent the flow rate to be higher than 10% of the nozzle nom-
inal flow rate.
It is recommended to use the pressure and flow rate regulating
valve (ECOVALVE) in order to achieve a more accurate spraying
method.
