1. Remove the cap, nozzle and lter.
2. Mount the calibrator cover to the lance.
3. Reinstall the lter, nozzle and cap.
4. Screw the calibrator onto the cover.
Record the time it takes to
walk 25 m²
Simulate the spraying of 25 m²
• 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.
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):
WARNING!
Wear a protective clothes to do the mainte-
nance and parts replacement.
NOTE: For the volume in liters per bushel (L / alk), simply multiply
the value obtained in liters per hectare (L / ha) by 2.42.
NOTE: This sprayer is packaged with Blue Adjustable Cone noz-
zle tted in the lance. Other nozzles mentioned in this manual
are optional, so they do not accompany this sprayer.
