After use, fill the sprayer part way with water. Start the
sprayer and allow clear water to be pumped through the
plumbing system and out through the spray wand and
boom. Refill the tank about half full with plain water and
use a chemical neutralizer such as Nutra-Sol® or equiv-
alent and repeat cleaning instructions. Flush the entire
sprayer with the neutralizing agent. Follow the chemical
manufacturer’s disposal instructions of all wash or
rinsing water.
Drain all water and chemical out of sprayer, paying
special attention to pump and valves. These items are
especially prone to damage from chemicals and
freezing weather. The sprayer should be winterized
before storage by pumping a solution of RV antifreeze
through the entire plumbing. Proper care and main-
tenance will prolong the life of the sprayer.
— OPERATION
This sprayer is designed to be attached to an ATV rack or
other stable surface. The pumping system draws solution
from the tank, through the strainer and to the pump. The
pump forces the solution under pressure to the spray wand
and spray boom. The pump has a pressure switch which
will shut the pump off when it reaches 60 PSI. Pressure
may be regulated by opening or closing the bypass valve
located on the top of the tank. Also, the spray nozzles can
independently be cycled on and off with the Y-valve
located on the top of the tank. See the illustration in this
manual for more details on using the bypass valve.
Regularly inspect the suction supply screen on the inside
of the tank. Flush with water to clear any accumulated debris.
WARNING:
Some chemicals will damage the pump valves if
allowed to soak untreated for a long period of time.Always flush
the pump with water after use. Do not allow chemicals to sit in
pump for extended times of idleness.Follow chemical man-
ufacturers instructions on disposal of all waste water from the
sprayer.
Chemical labels may show application rates in gallons per
acre. 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). 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 chem-
ical label carefully.
Determining the proper speed of the
tractor can be done by marking off 100, 200 and 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 chem-
ical to tank and 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
once the pump is turned on. The pressure will decrease
slightly when the boom is spraying.
— BOOMLESS NOZZLE SPRAY INFORMATION
When boom spraying, the recommended boom nozzle
height is 24”- 48” above ground level. (Fig. 4)and the pump
pressure should be between 14psi and 18psi (See tip
chart at the bottom of this page). The manifold has
three (3) valves; 2 for left/right spray control on the boom
and the other agitates and adjusts pressure. The pressure
is adjusted while the sprayer is running. We recommend
testing/setting theboom pressure using water. Turn the
pump on and open the ¼ turn valve to the boom; then
adjust the ¼ turn valve on the bypass/agitation line by
opening and/or closing the valve to the desired pressure
(your gauge will indicate pressure). Once desired pressure
has been set, turn off the valve to the boom and leave
the bypass/agitation valve set. It is normal to see a raise
in pressure while the pump is returning to the tank which
also helps to agitate the tank contents. The pressure is
set for the boom; you will also be able to use the wand
while the boom is off without adjusting the setting. The
pump will run until you shut off the pump with the in-line
on/off switch.
