IMPORTANT:
Remove tank lid and be sure the tank is
clean and free of any foreign material. Rinse tank out of
any tank residue before filling with water to test.
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.
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.
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 battery or the battery on your towing vehicle.
Connect to the positive (red) terminal first, then connect to the
negative (black) terminal. Then connect the end of the lead wire to
the end of the pump. When disconnecting, disconnect the end of the
pump wire from the lead wire, then disconnect the negative (black)
connection and finally the positive (red) connection. 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.
Activate the handgun by squeezing the handle lever
Rotating the adjustable nozzle tip on the handgun will change
the tip pattern from a straight stream to a cone pattern (fine
mist)
The (3) nozzles are fixed at 17-1/2” spacing
All (3) nozzles spraying at the same time will allow a maximum
coverage of 30 feet
The center nozzle will spray an 80” swath
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.
