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 to test this 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.
Fill the tank about 1/2 full with plain water and drive to the starting place for
spraying.
When you are ready to spray, close both valves on manifold (Detail A). This will
start solution spraying from the spray gun when trigger is pulled. The pressure
will decrease slightly when spraying.
Adjust the pressure by turning the
“
ON/OFF
”
valve lever on the
‘
Press.
Adj.
’
(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
‘
Press. Adj.
’
(bypass) valve. Regulating pressure is
done in this manner.
Read the operating instructions and initially begin spraying by closing both
valves (Detail A). This will enable the air in the line to be eliminated (purged)
through the tip, 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 spray-
er. 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.
Fill the tank part way with water and then add the desired amount of chemical to be sprayed. Finish filling tank to proper level.
Only fill 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 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

is off.
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.
Bypass valve is opened to re
-
circulate solution back into the tank.
When spraying with the handgun, pressure may be reduced by slowly opening the
‘
Press. Adj.
’
(bypass) valve until
desired pressure is achieved. Opening the valve decreases pressure, closing the valve increases pressure.
