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).

access the battery)
Step Sixteen: Check and test completed assembly.
WARNING
Check and test completed assembly Serious injury could result from chemical
leaks if sprayer is improperly assembled or the design of the sprayer is
modified. Follow the steps below to ensure the sprayer is properly assembled.
Never modify the sprayer design.
1. Check assembly
Check assembly to assure the sprayer is properly assembled and in safe working
condition:
a) Check that the gun clip screws are tight, hose clamps are secure, and
bolts/nuts are properly fastened.
b) While it is unlikely that factory assembled components become loose, they
should also be checked to make sure they are tight.

2. Test with water
Assembly
Test the system for leaks with water: a) Fill the tank with water. b) Connect
the remote switch to the pump power cord and turn the remote switch ON. The
pump is an “on demand” pump. When turned on, the pump will prime itself, and
then turn off. When the gun trigger is squeezed, the pump will automatically
start. c) Operate the spray gun by squeezing the gun trigger. d) Check for
leaks throughout the system. If a leak is detected, fix the leak and re-test
the system with water until no leaks are detected.

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.
