ASSEMBLY INSTRUCTIONS
You will find your Sprayer
assembled and ready to be
operated, less the hose,
which is separate from the
lance and the sprayer
pump. Connect the hose to
the outlet pump connector
and to the lance, and adjust
both ends with the two hose
clamps you will find inside
the strainer in the sprayer
cap.
The straps are padded and
provided with adjusting
buckles.
To assemble spraying
lance, press the trigger
lever (nº 6) and tighten the
plastic tip nut (nº 10) to the
bronze lance pipe. Lastly,
release the lever.
(Important: Never tighten
tip nut without pressing on
the trigger lever.)
The correct operating
position is when the top of
the tank is on the same level
as the operator neck.

a) Mark a field area of 328 ft (square
of 32.8 x 32.8 sq or 328 sq ft x 3.28 ft)
b) Fill the tank with clear water and
apply over the marked area keeping
a constant pumping and walking
rhythm.
c) Calculate the flow rate in gallons by
hectare using the following formula:
Q = Flow rate in gallons
2
32800= ft correspond with 1 hectare
2
A = Applied area (328 ft )
Q = Vol. x 328002 ft
A=328 ft

d) If the flow rate is not in accordance
with your needs, change to a larger or
smaller nozzle according to the
results.
a) Fill bucket with 1.3 gallons of
clear water and add the chemical.
