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 VERY important for you to test your sprayer with plain water before actual
spraying is attempted. This will enable you to check the sprayer for leaks with-
out the possibility of losing any expensive chemicals.
Fill the tank about 1/2 full with plain water and drive to the starting place for spraying.
When you are ready to spray, turn the boom valve to the “on” position (Detail A). 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 (Detail
B). Make sure your pattern is sufficient. You may down-pressure the system by
‘bypassing’ solution back into the tank. This is achieved by opening the bypass valve.
Regulating pressure is done in this manner.
Read the operating instructions and initially begin spraying by closing the ‘Pressure Ad-
just’ valve and opening the boom line valve (Detail A). 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 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:
Handgun lever is squeezed to spray the handgun.
Boom valve is opened to broadcast spray with the boom.
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 deter-
mined 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.
