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.
After Spraying
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.
Winter Storage
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 automotive antifreeze (containing a rust inhibitor) 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. Proper care and maintenance will prolong the life
of your sprayer.
IMPORTANT:
Remove tank lid and be sure the tank is clean
and free of any foreign material. Rinse tank out of any tank
residue before filling with water to test.
Testing the Sprayer
Note: add proper oil to the engine crankcase and gasoline
to the gas tank. Refer to the engine manual for the correct
type and amount.
NOTE:
It is important to test the sprayer with plain water before actual
spraying is attempted. This will enable you to check the sprayer for
leaks in the plumbing system, without the possibility of losing any
Expensive chemicals.
Open the valve in the suction line and allow water to flow to the
pump. The valve is located at this point to enable the strainer to be
taken apart for cleaning.
CAUTION: Always be sure that water has reached the roller pump
before starting your sprayer. If the pump is run dry, serious damage to
the pump will result
2.
It is always best to start the sprayer at little or no pressure. This
sprayer is equipped with a spring loaded relief valve. Turn the
valve knob out to decrease pressure and in to increase pressure.
3.
You may now start the engine following the engine manufacturers
instructions. Let the sprayer run at low pressure until water has
reached the handgun and all air has been purged from the system.
The pressure should now be increased to 30-125 P.S.I. Operate the
sprayer at this increased pressure for 3-5 minutes, thoroughly testing
the unit before adding chemicals.
Add water to the tank and drive to the starting place for spraying. When
you are ready to spray, position booms out for spraying and 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 twisting the gray twist knob on the
bypass (pressure relief) valve. Twist ‘clockwise’ to increase pressure ,
‘counter-clockwise’ to decrease pressure.
Read the operating instructions and initially begin spraying by closing
the ‘bypass’ valve and opening the boom line valve. 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 and 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) before application!
Operation
Always fill tank 1/2 full with water first and then add the chemical slowly,
mixing as you pour the chemical into the tank and fill the rest of the
way. You may use the bypass 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.
Activate 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 (fine mist)
This sprayer is designed to be towed behind a garden tractor. 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.
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 2 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).
