Intended Use
The sprayer is intended for use in spraying agricultural pesticides.
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.
Sprayers 282780 and 282785 come equipped with a spot spray gun and a broadcast boom. Use the spot spray gun if you desire to apply pesticide only on selected plants. Use the broadcast boom if you wish to spray large ground areas.
SPRAYING OTHER LIQUIDS: In addition to spraying pesticides, this sprayer may be used for watering plants and trees. 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. NOTE: The sprayer will be damaged and warranty voided if used to apply bleach, chlorine, ice control chemicals, or any petroleum based product (gasoline, diesel, kerosene, oil).

Appendix A ­Broadcast Spray Calibration Tables

Below are some guidelines to help you calibrate your tow behind broadcast sprayer. This is a very important step in operating the tow behind broadcast sprayer such that too much or too little chemical may be applied. 1. Using Table 1, find a table that corresponds with the chemical manufacturer’s suggested application rate (gallons per acre, gallons per 1000 sq. ft., or gallons per 100 sq. ft.). 2. Find the application rate that is closest to the chemical manufacturer’s recommendations. 3. The speed to drive your ATV is listed below the application rates.
