Testing the Sprayer
NOTE:
It is VERY important for to test your sprayer with plain water
before actual spraying is attempted. This will enable you to check for
leaks without the possibility of losing any expensive chemicals.
Operation
Always fill the tank 1/2 full with water first and then add the chemical
slowly, mixing as you pour the chemical into the tank and then fill the
rest of the way. You may use your handgun or the bypass line in
order to mix the chemical and water.
Initially begin spraying by opening the handgun/boom. This will ena-
ble the air in the line to be purged through the handgun tip/boom tip,
while building pressure.
Adjusting Pressure
When the bypass valve is closed, pressure is at the highest
point.
Opening the valve will decrease pressure.
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) before application!
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 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 num-
ber 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.
After testing, add water and proper amount of chemical to the tank
and drive to the starting place for spraying. Adjust the pressure and
spray as you did in the testing procedure.
Using the Boom Nozzle
Four things must be considered before spraying with the boom.
How much chemical must be mixed in the tank.
Rate of spray (gallons per acre to be sprayed).
What pressure (p.s.i.) will be used.
Speed traveled (mph) while spraying.
Refer to the chemical label to determine your chemical mixture
See the tip chart to determine the pressure to be used. The
chart will also show the speed used when spraying.
Start the pump and open the valve to the boom nozzles.
Check the spray pattern. Usually you can see the coverage
better on a solid concrete surface, such as a driveway.
Maintenance During/After Spraying
Periodically check the strainer and clean the screen on your intake
line. Proper care and maintenance will prolong the life of your spray-
er.
After use, fill the sprayer half way with clean water. Start the pump
and allow the water to pump through the entire plumbing system and
nozzles. Drain and then refill half full, add the recommended amount
of a good quality tank cleaner, such as FIMCO Tank Neutralizer and
Cleaner. (If no tank cleaner is available, you may substitute dish
soap for this step). Turn pump on and circulate through system for
15 minutes and then spray out through boom and handgun nozzles.
Refill sprayer half way with clean water and repeat. Follow the chem-
ical manufacturer’s disposal instructions of all wash or rinsing water.
If boom nozzle needs cleaning, remove them from the sprayer and
soak in warm soapy water. Clean with a soft bristled brush or tooth-
pick if necessary. Never use a metal object. Even the slightest dam-
age can change the flow rate and spray distribution. Water rinse and
dry before storing.
WARNING:
Some chemicals will damage the pump valves if al-
lowed to soak untreated for a length of time! ALWAYS flush the
pump as instructed after each use. DO NOT allow chemicals to sit in
the pump for extended times of idleness. Follow the chemical manu-
facturer’s instructions on disposal of all waste water from the spray-
er.
Winter Storage
Before storing your sprayer for winter or long term storage, thorough-
ly clean and drain it as much as possible. Then pour enough pink RV
antifreeze into the tank so that when the pump is turned on you can
pump the antifreeze throughout the entire plumbing system, includ-
ing the bypass. Make sure to operate the boom and handgun until
you see pink fluid spraying from the nozzles. Leave any remaining
antifreeze in the tank. Before your next usage, rinse the antifreeze
from the sprayer with clean water.
It is nearly impossible to drain all of the water from the sprayer and
any trapped water can freeze in cold weather and damage parts of
the sprayer. Pumping the antifreeze through the system will displace
the water and help prevent this damage
Proper care and maintenance will prolong the life of your sprayer.
