Intended Use
4
The sprayer is intended for use in spraying residential, commercial, or agricultural
pesticides and other non-flammable liquids.
SPRAYING PESTICIDES:
Pesticides are hazardous chemicals that must be handled with caution as directed
throughout this manual and on the pesticide label. Pesticides are regulated by the United
States Environmental Protection Agency (EPA) and defined as:
Any substance or mixture of substances intended for preventing, destroying, repelling, or mitigating any
pest. Though often misunderstood to refer only to insecticides, the term pesticide is a comprehensive
term that applies to insecticides, herbicides, fungicides, and various other substances used to control
pests.
The sprayer is intended for use in spraying pesticides in liquid form only. The sprayer is
NOT intended for use in spraying pesticides in dry or aerosolized form, or for use with
fumigants.
Some formulations of liquid pesticides do not remain in solution and should be agitated
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.)
This sprayer comes equipped with a spray gun for applying pesticides on selected plants.
If you wish to spray large ground areas, a broadcast kit (Item #5042381), is available as
an optional accessory.
SPRAYING OTHER LIQUIDS:
In addition to spraying pesticides, this sprayer may be used to spray other non-flammable
liquids. Example uses includes watering plants/trees or spraying water for dust control.
However, WE RECOMMEND THAT THE SPRAYER NOT BE USED FOR
OTHER PURPOSES ONCE IT HAS ALREADY BEEN USED FOR SPRAYING
PESTICIDES. Any chemical will leave some residual in the tank liner or sprayer
components, even after the sprayer has been properly cleaned. These residual chemicals
can have unexpected effects on future uses. For example, spraying water or other liquids
that are contaminated with residual pesticide may result in unforeseen hazards to plant or
animal life.
Contact NorthStar Product Support at 1-800-270-0810 for any questions
about the appropriate use of the sprayer and/or optional accessories.
