Testing the Sprayer
NOTE: It is important that you test your sprayer for leakage and
proper spray patters with plain water before chemical application
is attempted. This will also give you the opportunity to familiarize
yourself with the operation of the sprayer, without the possibility
of losing any expensive chemicals.
Add water to the tank and drive to the starting place for spraying. When
you are ready to spray, position booms for spraying and turn the boom
valve to the “on” position. This will start solution spraying from the tips of
the boom. The pressure will decrease slightly when the boom is
spraying. Adjust the pressure by turning the “ON/OFF” valve lever on
the bypass line valve.
Read the operating instructions and initially begin spraying by closing
the ‘bypass’ valve and opening the boom line valve. This will enable the
air in the line to be eliminated (purged) through all the tips, while
building pressure. When everything tests all right (no leaks and good
pressure), add the desired chemicals to the mixture and water
combination and start your spraying operation. Adjust the pressure and
spray as you did in the testing procedure.
Conditions of weather and terrain must be considered when setting the
sprayer. Do not spray on windy days. Protective clothing must be worn
in some cases
Be sure to read the chemical label(s) before application!
Operation
The pumping system draws solution from the tank, through the strainer
and to the pump. The pump forces the solution under pressure to the
handgun or boom nozzles.
Connect the lead wire to a fully charged 12 volt battery. You may use
either a stand-alone batter or the battery on your towing vehicle. The
lead wire has an On/Off switch to activate the pump. “-” is on and “O” is
off.
Fill the tank part way with water and then add the desired amount of
chemical to be sprayed. Finish filling tank to proper level. Turn the pump
on by depressing the “-” side of the rocker switch. The pump is
equipped with a pressure switch that is pre-set at the factory to shut the
pump off when all discharges are closed.
The pump will turn back on when one of the following actions occurs:
the handgun lever is squeezed to spray the handgun, or the boom valve
is opened to broadcast spray with the boom, or the bypass valve is
opened to re-circulate solution back into the tank.
When spraying with either the boom or the handgun, pressure may be
reduced by slowly opening the bypass valve until desired pressure is
achieved. Opening the valve decreases pressure, closing the valve
increases pressure. When spraying with the boom, the proper method
to set the pressure is to open the boom valve completely and if a lower
pressure is desired, then slowly open the bypass valve until that
pressure is obtained.
For the safest and most efficient chemical application, you will need to
calibrate your sprayer using the tip and speed charts. Once you have
determined the proper speed and pressure settings, you will need to

consult your chemical label for the amount of chemical to be added to
the tank. Read the entire label. Use only according to label directions.

Rotating the adjustable nozzle tip on the handgun will change the
tip pattern from a straight stream to a cone pattern (fine mist)
x
The (3) nozzles are fixed at 17-1/2” spacing
x
All (3) nozzles spraying at the same time will allow a maximum
coverage of 30 feet
x
The center nozzle will spray an 80” swath
x
Each of the (3) nozzles has a shutoff valve, so you can shut off
each nozzle individually. This may help in achieving the actual
coverage needed for your application.
Calibration
Chemical labels may show application rates in gallons per acre, gallons
per 1000 square feet or gallons per 100 square feet. You will note that
the tip chart shows 3 of these rating systems. Once you know how much
you are going to spray, then determine (from the tip chart) the spraying
pressure (PSI), and the spraying speed (MPH).
Determining the proper speed of the pulling vehicle can be done by
marking off 100, 200 & 300 feet. The speed chart indicates the number
of seconds it takes to travel the distances. Set the throttle and with a
running start, travel the distances. Adjust the throttle until you travel the
distances in the number of seconds indicated by the speed chart. Once
you have reached the throttle setting needed, mark the throttle location
so you can stop and go again, returning to the same speed.
Add water and proper amount of chemical to the tank and drive to the
starting place for spraying
Using the Boom Nozzles
Four things must be considered before spraying with the boom.
How much chemical must be mixed in the tank.
Rate of spray (gallons per acre to be sprayed).
What pressure (p.s.i.) will be used.
Speed traveled (mph) while spraying.
Refer to the chemical label to determine your chemical mixture
See the tip chart to determine the pressure to be used. The chart
will also show the speed used when spraying.
Start the pump and open the valve to the boom nozzles.
Check the spray pattern. Usually you can see the coverage better
on a solid concrete surface, such as a driveway.
The boomless nozzles should be approx. 33” above the objects
being sprayed.
