Assembly
1. Install the tank mounting plates to the tank as shown in the
exploded view drawing. (if not done so already)
2. Place the tank, with the brackets attached, to your ATV carrier
rack. Attach the mounting brackets to the cross members of the
rack, using the hardware supplied. (See exploded view drawing)
3. Join the nozzle mounts (RH & LH) to the tank mounting
brackets with the hardware shown.
4. Attach the nozzle assemblies to the nozzle mounts with the
(2) clips as shown. Make sure the u-bolts are fastened through
the bracket(s) and up into the tank mounting bracket(s). Connect
the (2) hoses to these nozzle assemblies. Secure with a hose
clamp. The other ends of these hoses get attached to the "Y"
valve on of the manifold. Each nozzle will have its own shut-off
valve control.
5. Thread the pressure gauge into the reducing bushing at the
far end of the manifold assembly. Use a good grade of thread
sealant, or teflon tape, to insure no leaks.
6. Connect the wiring harness to the rear of the pump. Clip the

Operation
Your sprayer is equipped with (2) ON/OFF switches. One is on
the wire assembly that you hook up to your battery, the other is
on the pump itself, on the opposite end of the pressure switch.
The "-" is the "ON" position and the "o" is the "OFF" position for
the switches. Make sure both switches are depressed in the "-"
position for operation.
In addition to the ON/OFF switch, the pump is equipped with
an electronic pressure switch that is factory pre-set for it to
shut off at 45 p.s.i.. This switch assembly is the 'square box' on
the head portion of the pump.
Always fill the tank with a desired amount of water first, and
then add the chemical slowly, mixing as you pour the chemical
into the tank. You may use the handgun to spray into the
solution in order to mix the chemical and water.
Initially begin spraying by opening the handgun. This will
enable the air in the line to be purged through the handgun tip,
while building pressure.
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).
The pump's electronic pressure switch shuts the motor off •
when all lines are closed. The system will remain
pressurized, and the pump motor will restart automatically
when either the handgun, or boom line is opened. If the
bypass line valve is in the open position, the pump will not
shut off automatically.
Both nozzles spraying at the same time will allow a •
maximum coverage of 28 feet.
When it becomes necessary to clean the screen, you will •
need to shut off the ON/OFF valve down by the tank, on
the inlet side of the pump. Next, unscrew the knurled nut on
the outside of that valve. Remove the screen/washer which
is located in the knurled nut at that location. Rinse and tap
out the dirty screen and put back in it's original position
when clean. Do this on a regular basis to maintain a clean
screen.
Adjusting Pressure
- When the bypass valve is closed, pressure is at the highest
point.
- Opening the valve will decrease pressure.
Testing the Sprayer
NOTE:
It is VERY important for you to test your sprayer with plain
water before actual spraying is attempted. This will enable
you to check the sprayer for leaks, without the possibility of
losing any expensive chemicals.
Add water to the tank & drive to the starting place for spraying.
When you are ready to spray, turn the boom valves to the "on"
positions. 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 turning the "ON/OFF" valve lever
on the bypass line valve.
Read the operating instructions and Initially begin spraying by
closing the 'bypass' valve (this is the center ON/OFF valve
located at the center port of your manifold assembly) and opening
the boom line "Y" valves. This will enable the air in the lines to be
eliminated (purged) through all the tips, while building pressure.
When everything tests all right (no leaks, & 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) correctly!
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 all 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.

PSI = Pounds Per Square Inch / GPM = Gallons Per Minute
Gallons per Acre Based on Water - 17 1/2" Spacing
Note: The same figures are used for 1, 2, or 3 nozzles.
Rate Chart for Boomless Nozzles
Gallons per 1000 Sq. Ft. Based on Water - 17 1/2" Spacing
Gallons per 100 Sq. Ft. Based on Water - 17 1/2" Spacing
MPH = Miles Per Hour / FPM = Feet Per Minute
The only difference will be with the width of the spray swath.
** The rate of spray as shown in the chart will remain the same with 1 or 2 Nozzles. **

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.

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 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.
Proper care and maintenance will prolong the life of your sprayer.
Using the Boom Nozzles
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 (mph) while spraying. 4.
- 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 valves 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.
