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 lling with water to test.
Tesng the Sprayer
NOTE:
It is VERY important to test this sprayer with plain water before actual spraying is aempted. This will enable you to check the
sprayer for leaks without the possibility of losing any expensive chemicals.
Fill the tank about 1/2 full with plain water and drive to the starng place for spraying.
When you are ready to spray, turn the boom valve to the “on” posion (Detail A). This
will start soluon spraying from the ps 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 Press Adj. valve (Detail
B). Make sure your paern is sucient. You may down-pressure the system by
‘bypassing’ soluon back into the tank. This is achieved by opening the press adj. valve.
Regulang pressure is also done in this manner.
Read the operang instrucons and inially 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 ps, while building pressure. When every-
thing tests all right (no leaks and good pressure), add the desired chemicals to the
mixture and water combinaon and start your spraying operaon.
Condions of weather and terrain must be considered when seng the sprayer. Do not
spray on windy days. Protecve clothing must be worn in some cases.
Be sure to read the chemical label(s) before applicaon!
Operaon
The pumping system draws soluon from the tank, through the strainer and to the
pump. The pump forces the soluon under pressure to the handgun or boom nozzles.
Fill the tank part way with water and then add the desired amount of chemical to be
sprayed. Finish lling tank to proper level.
Only ll the tank with what you’re going to spray in a day, never leave chemicals sit in
tank.
Connect the lead wire to a fully charged 12 volt baery. You may use either a stand-
alone baery or the baery on your towing vehicle.
Connect to the posive (red) terminal rst, then connect to the negave (black) termi-
nal. Then connect the end of the lead wire to the end of the pump. When disconnecng,
disconnect the end of the pump wire from the lead wire, then disconnect the negave
(black) connecon and nally the posive (red) connecon. The lead wire has an On/O
switch to acvate the pump. “-” is on and “O” is o. 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 o when all discharges are closed.
The pump will turn back on when one of the following acons 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 soluon back into the tank.
When spraying with either the boom or the handgun, pressure may be reduced by slowly opening the bypass valve unl 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 unl that pressure is obtained. Adjust the pressure and spray as you did in the tesng procedure.
For the safest and most ecient chemical applicaon, you will need to calibrate your sprayer using the p and speed charts. Once
you have determined the proper speed and pressure sengs, you will need to consult your chemical label for the amount of chem-
ical to be added to the tank. Read the enre label. Use only according to label direcons.
