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 all 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.
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.
Add water to the tank & drive to the starting place for
spraying. When you are ready to spray, 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. Adjust the pressure by turning the
"ON/OFF" valve lever on the bypass line valve.
Read the operating instructions and Initially begin spraying by
closing the 'bypass' valve (this is the center ON/OFF valve
located at the center port of your manifold assembly) and
opening the boom line valve (this is the 'other' valve on the
manifold). 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, & 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) correctly!
WARNING:
Some chemicals will damage the pump valves if
allowed to soak untreated for a length of time! ALWAYS
thoroughly flush the pump with water after use. DO NOT
allow chemicals to sit in the pump for extended times of
idleness. Follow the chemical manufacturer's instructions on
disposal of all waste water from the sprayer.
Operation
Your sprayer is equipped with (2) ON/OFF switches. One is
on the wire assembly that you hook up to your battery, the
other is on the pump itself, on the opposite end of the
pressure switch. The "-" is the "ON" position and the "o" is
the "OFF" position for the switches. Make sure both switches
are depressed in the "-" position for operation.
In addition to the ON/OFF switch, the pump is equipped with
an electronic pressure switch that is factory pre-set for it to
shut off at 60 p.s.i.. This switch assembly is the 'square box'
on the head portion of the pump.
Always fill the tank with a desired amount of water first, and
then add the chemical slowly, mixing as you pour the
chemical into the tank. You may use the handgun to spray
into the solution in order to mix the chemical and water.
The pumping system draws solution from the tank, through
the strainer/filter, and to the pump. The pump forces the
solution under pressure to the handgun and/or boom
nozzles.
Open 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 (finer mist).
This sprayer is designed to be towed behind a garden
tractor.
The nozzles on the boom will spray an 80 inch wide swath.
Check the nozzle pattern by spraying water on a concrete
surface. Raise the boom to a higher mounting position to get
more spray pattern overlap, if desired.
