Operation – Using the Sprayer
1. De cide if agitation is re quire d
Some formulations of liquid pesticides do not remain in solution and should
be agitate d to maintain a uniform mix.
This sprayer is equipped with an agitator that should be used when spraying
pesticides classified as " flowable" (" F" or "L"), " wettable powder" (" WP" or
"W"), " emulsion" ("EC" or " E"), "microencapsulated" ("M"), or water
dispersible granules ("WDG" or " DF"). (See pesticide label to determine its
classification.)
2. O peration principle :
The nozzle design creates a venturi effect, speeding up the flow of the
fluid as it exits the nozzle. This increase in velocity creates a low-
pressure area (a vacuum) which draws in additional fluid from the tank,
multiplying the outlet flow for increased agitation.
3. Tuning the agitator
The four colored nozzles in the manual bag are used to tune your agitator. The
following chart outlines the sizes, flows and pressures with each tip. A higher
inlet flow for a given tip will create a higher pressure in the agitator.
Orifice Color Code
1/8 Yellow/Black
5/32 Red
3/16 Blue
1/4 Natural
*NOT E: With the 1/8 orifice tip you will have more pressure to the gun or
broadcast nozzles and a less effective agitator. With the ¼ orifice tip you will
have less pressure to the gun or broadcast nozzles and a more effective agitator.
Insert the tip that gives you the desired amount of pressure and agitation.
a. Unscre w the agitator from the bulkhead fitting on the inside of the
tank.
b. Insert the de sire d nozzle as shown.
c. Scre w agitator back into the bulkhead fitting.
