The Sprayer is now ready to TEST w/plain water before actual use

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 this 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). It does not matter if the line to the spray gun is open or closed. When the boom valve is open it will start solution spraying from the tips of the boom. The pressure will decrease slightly when the boom is spraying.
Read the operating instructions and initially begin spraying by 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 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

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.
The pump will turn back on when one of the following actions occurs:

• Handgun lever is squeezed to spray the
• Boom valve is opened to broadcast spray with the

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 (this sprayer will spray at the 30 PSI range from the chart on the next page), 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 according 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 the spraying pressure (this sprayer will spray at the 30 PSI range), 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.

1. How much chemical must be mixed in the tank.
2. Rate of spray (gallons per acre to be sprayed).
3. What pressure (p.s.i.) will be used. (Sprayer will spray at the 30 PSI range)
4. Speed traveled (mph) while spraying.

• Refer to the chemical label to determine your chemical mixture

• Start the pump and open the valve to the boom
• Check the spray 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.

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 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 allow 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 intake hose and/or 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. Half-Moon counterweight and bearing are seized up.

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.

Motor not running: Checking the Pressure Switch.

If your motor is not running and you’ve checked the following: for loose wiring connec- tions, fuse, the switch on the lead wire was “ON” and made sure you were connected to a fully charged battery and everything is fine, but the motor won’t run, then it’s time to check to see if the pressure switch is bad.

• Remove the cover off the 1” square box (pressure switch) on the head of the pump, the cover is held on by one phillips-head This will expose the two red wires.
• With the pump connected to a good 12 volt power source and everything
• Slip the two red wires off the terminals and touch them

If the motor runs, it means the pressure switch is bad and needs to be replaced.
If it still doesn’t run, try bypassing the switch in the lead wire or using another lead wire. Even if a tester shows power to the pressure switch, it still could be the switch in the wire that is causing the problem.
If still not responsive, use a voltmeter or electrical tester to make sure you are getting power to the head of the pump, as it could possibly be something in one of the wires or even the lead wire assembly may need to be replaced.
Warning: It is NOT recommended to run the pump this way, as the pump will continue to run and not shut off.
This could result in blown hoses when all discharges are closed. Also, this could result in premature failure of the pump completely.

Motor Running – BUT Little to No Pressure :

If your strainer is clean…. CHECK:
Both the counterweight and the bearing need to spin freely and both need to spin INDEPENDENTLY of each other. If these 2 pieces are ‘stuck’ together, you will need to break them free and whether or not they are sticking, spray some good quality lubricant or something similar on them and let it soak in and this should restore most of your prime.
