The performance of any agricultural chemical depends upon
the proper application
The tips supplied as standard with the sprayer can be used for
a wide variety of spraying applications. Other tip sizes are
available for different coverages. The speed and pressure
charts shown indicate the rates can be changed considerably
by changing speed and pressure. The nozzles on the boom will
spray a 100" wide swath. The proper nozzle height is 17" to 20"
above the object being sprayed.
Check the spray patterns. Each nozzle should overlap the next
nozzle approximately 30%.
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).
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.
When you are ready to spray, mix chemicals as follows. Add
the proper amount of water to the tank. Run the sprayer while
adding chemical to the water. Do NOT spray through the boom
at this time. This will allow the solution to return (or 'bypass') to
the tank. The movement of solution through the bypass will aid
in mixing the water and chemicals. You should now be ready to
spray.
Operation & Calibration
- Four things must be considered before spraying with the boom:
How much chemical must be mixed in the tank?
1.
Rate of spray? (Gallons per Acre to be sprayed)
2.
What Pressure (p.s.i.) will be used?
3.
Speed Traveled (m.p.h.) while spraying?
4.
- Refer to your chemical's label to determine the chemical mixture.
- See the tip chart to determine the pressure to be used. The chart
will also show the speed used when spraying.
- If the towing vehicle does not have a speedometer, speed can
be determined as per the directions.
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.
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). The pressure can be set by running the sprayer
with the boom nozzles 'on', and then adjusting the relief valve until
the gauge reads the desired pressure. Notice that the pressure
will go up when the boom line is shut off. This is normal, and the
pressure will return as before when you open the boom line.
When selecting pressure from the tip chart, it is a good idea to try
for the 20 or 30 p.s.i. range as this allows an excellent nozzle
pattern. Spraying at 10 p.s.i. begins to break up the pattern, and
at 40 p.s.i. you may notice some drift.
