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 without the possibility of losing any expensive chemicals.
Important:
After any repair work has been done, ALWAYS test for leaks with water before using.
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 (Press Adj) 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 (Press Adj) valve. Regulating pressure is done in this manner.
Read the operating instructions and initially begin spraying by closing the ‘Pressure Adjust’ 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 pres-
sure. 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 discon-
nect 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. Only fill
the tank with what you’re going to spray in a day, never leave chemicals sit in tank.
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 (Press Adj) 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 (Press Adj) 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
(Press Adj) 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.
