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:
It is VERY important to test the 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.
Important: After any repair work has been done, ALWAYS test for leaks with water before using.
Fill the tank about 1/2 full with plain water and drive to the starting place for spraying.
When you are ready to spray, turn the boom valve to the “on” position (Detail A). 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 (Press Adj) line valve (Detail B). Make sure your
pattern is sufficient. You may down-pressure the system by ‘bypassing’ solution back into the tank. This is achieved by
opening the bypass (Press Adj) valve. Regulating pressure is done in this manner.
Read the operating instructions and initially begin spraying by closing the ‘Pressure Adjust’ valve and opening the boom
line valve (Detail A). This will enable the air in the line to be eliminated (purged) through all the tips, while building pres-
sure. 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
The pumping system draws solution from the tank, through the strainer and to the
pump. The pump forces the solution under pressure to the handgun or boom
nozzles.
Fill the tank part way with water and then add the desired amount of chemical to be
sprayed. Finish filling tank to proper level.
Only fill the tank with what you’re going to spray in a day, never leave
chemicals sit in tank.
Connect the lead wire to a fully charged 12 volt battery. You may use either a stand
-alone battery or the battery on your towing vehicle. Connect to the positive (red)
terminal first, then connect to the negative (black) terminal. Then connect the end of
the lead wire to the end of the pump. When disconnecting, disconnect the end of
the pump wire from the lead wire, then disconnect the negative (black) connection
and finally the positive (red) connection. The lead wire has an On/Off switch to
activate the pump. “-” is on and “O” is off.
Turn the pump on and by depressing the “-” side of the rocker switch. The pump is
equipped with a pressure switch that is pre-set at the factory to shut the pump off
when all discharges are closed. Only fill the tank with what you’re going to spray in
a day, never leave chemicals sit in tank.
The pump will turn back on when one of the following actions occurs:
 Handgun lever is squeezed to spray the handgun.
 Boom valve is opened to broadcast spray with the boom.
 Bypass (Press Adj) valve is opened to re-circulate solution back into the tank.
When spraying with either the boom or the handgun, pressure may be reduced by
slowly opening the bypass (Press Adj) valve until desired pressure is achieved.
Opening the valve decreases pressure, closing the valve increases pressure. When
spraying with the boom, the proper method to set the pressure is to open the boom
valve completely and if a lower pressure is desired, then slowly open the bypass
(Press Adj) valve until that pressure is obtained.
For the safest and most efficient chemical application, you will need to calibrate
your sprayer using the tip and speed charts. Once you have determined the proper
speed and pressure settings, you will need to consult your chemical label for the
amount of chemical to be added to the tank. Read the entire label. Use only accord-
ing to label directions.

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 dis-
tances. 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.
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.
Maintenance During/After Spraying
Periodically check the strainer and clean the screen on your intake line.
If sprayer becomes clogged during use, discontinue use immediately. DO NOT attempt to service while chemicals are in
the sprayer and power is connected.
Proper care and maintenance will prolong the life of your sprayer.
After use, drain the tank and store or dispose of chemical properly. 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, about 1-2 oz. per gallon). But a neutralizer/cleaner
should be used to thoroughly clean the system. 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 chemical
manufacturer’s disposal instructions of all wash or rinsing water.
If boom or handgun nozzles need cleaning, remove them from the sprayer and soak in warm soapy water. Clean with a
soft bristled brush or toothpick if necessary. Never use a metal object. Even the slightest damage can change the flow
rate and spray distribution. 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.

Tank Care & Maintenance
Warning: Do not use the tank as a container for fuel oils, kerosene, gasoline or any other petroleum distillate product.
All polyolefins are softened and permeated by such products. In an enclosed area the vaporization of these materials
from the outside surface of the tank could create a dangerous condition.
The tank should not be used as a pressure vessel nor used with chemicals or solutions having a weight of more than 12
pounds per gallon.
Store the tank in a dry dark place when not in use. Storage out of sunlight will prolong the life of the tank.
Do not drop, strike or kick the tank, especially at low temperatures. Tanks become brittle and are subject to cracking at
temperatures below 20° Fahrenheit.
Always flush the tank with water and a neutralizing agent at the end of each use, to prevent contamination of solutions.
Winter Storage
Prepare the sprayer for end-of-season storage by running RV antifreeze through the system. This will keep internal parts
lubricated, protect against corrosion and keep the unit from freezing. Note: RV antifreeze is non-toxic and biodegradable
and generally safer for the environment than automotive antifreeze.
Before storing your sprayer for winter or long term storage, thoroughly 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, including 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.
Removing from storage: drain the antifreeze. Fill the tank with fresh water and run through the system. Dispose of
antifreeze and flush water properly.
Before Troubleshooting or Attempting to Service the Pump:
♦ Review Troubleshooting Chart: Do Not attempt to repair until steps below are followed.
♦ Personal Protective Gear: Wear protective gear when servicing pump.
♦ Disconnect Power: Disconnect the power to the pump and relieve the pressure from the system.
♦ Empty and Flush the pump system with water, never attempt to service the pump until it has been emptied and
flushed.
♦ Perform Repairs: Follow directions provided in the troubleshooting section to repair the pump.
♦ Test: Always test the pump for leaks with plain water after any repairs before using.
Sprayer and Pump FAQs:
♦ Why does the pump not run all the time? This is an on-demand pump and only runs when a discharge is open
(spray gun, bypass, boom (if applicable) or a leak is in the system.
♦ Why does the pump surge while using the spray gun? Low flow/high pressure may cause the pump to surge (or
cycle). Typically the spray wand is adjusted at too fine of a mist, to overcome, adjust the nozzle for a higher flow.
♦ How do I adjust the pressure? Pressure can only be adjusted by opening the pressure adjust (bypass) valve to al-
low some of your water or solution to return to the tank (if equipped).
♦ Pump quit and will not run, what do I need to do? Squeeze trigger on spray gun to ensure that the system isn’t
just pressurized up with discharges closed.
Check electrical connections, ensure switch is on. Check fuses. Check for proper voltage. Check pressure switch.
♦ Low flow or no flow at all, what do I need to check for? Check for a clogged or kinked intake hose and/or clogged
intake strainer. Check for proper voltage.
You will need to occasionally check your intake strainer to ensure that it is clean of any debris.
♦ What is causing the fuse to blow each time I turn the pump on? Check for excessive voltage. Improper adjustment
of the pressure switch. Damaged or defective wire harness or defective pressure switch.
Warning:
Ensure the wiring harness does not become pinched or damaged in any way. This may damage the pump or cause
the wiring harness to overheat, resulting in a melt down or fire.
