Using the Boom Nozzles
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.
The boomless nozzles should be approx. 33" above the objects being
sprayed.
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 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.
Adjusting Pressure
When the bypass valve is closed, pressure is at the highest point.
Opening the valve will decrease pressure.

Maintenance During/After Spraying
Proper care and maintenance will prolong the life of your sprayer.
After use, fill the sprayer tank part way with water. Start the sprayer
and allow the clear water to be pumped through the plumbing system
and out through the spray nozzles. Refill the tank about half full with
plain water and use FIMCO Tank Neutralizer and Cleaner and repeat
cleaning instructions above. Flush the entire sprayer with the
neutralizing/cleaning agent, then flush out one more time with plain
water. Follow the chemical manufacturer's disposal instructions of all
wash or rinsing water.
For the boom (if applicable) remove the tips and screens from the
nozzle assemblies. Wash these items out thoroughly. Blow the orifice
clean and dry. If the orifice remains clogged, clean it with a fine
bristle (NOT WIRE) brush or with a toothpick. Do not damage the
orifice. Water rinse and dry the tips before storing.
WARNING:
Some chemicals will damage the pump valves if
allowed 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 manufacturer's instructions on disposal of all waste
water from the sprayer.
Drain all water out of your sprayer, paying special attention to the
pump, handgun and valve(s). 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 system. This
antifreeze solution should remain in the plumbing system during the
winter months. When spring time comes and you are preparing your
sprayer for the spray season, rinse the entire plumbing system out,
clearing the lines of the antifreeze solution.
