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 (this is the valve marked Press. Adj. on your
manifold assembly) and opening the boom line valve (this is the
center valve on the manifold). 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!
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.
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 and 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.
The nozzles on the boom will spray an 80 inch wide swath. Check
the nozzle pattern by spraying water on a concrete surface.
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.
Raise or lower the nozzles so that you will have a good
coverage pattern. Generally the proper height will be about 18
inches from the object(s) being sprayed.
