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 important that you test your sprayer for leakage and proper spray patters with plain water before chemical application is attempted. This will also give you the opportunity to familiarize yourself with the operation of the sprayer.
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.
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. The lead wire has an On/Off switch to activate the pump. “-” is on and “O” is off.
Fill the tank part way with water and then add the desired amount of chemical to be sprayed. Finish filling tank to proper level. 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 the handgun lever is squeezed to spray.
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 (finer mist)
Maintenance During/After Spraying
Periodically check the strainer and clean the screen on your intake line.
Checking/Cleaning the sprayer’s filter/screen:
Empty the tank
Unscrew the knurled nut from the tank.
Swing (swivel) the intake assembly towards you. Look in the nut you
JUST unscrewed. There is a screen/washer there.
Remove the screen and clean as necessary. Replace when done and reassemble the entire assembly .
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).
Turn pump on and circulate through system for 15 minutes and then spray out through handgun nozzle. Refill sprayer half way with clean water and repeat. Follow the chemical manufacturer’s disposal instructions of all wash or rinsing water.
If handgun nozzle needs cleaning, remove 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.
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 handgun until you see pink fluid spraying from the nozzle. 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.

Troubleshooting the Pump:
Motor does not run:
Check for loose wiring connection(s).
Make sure the 'ON/OFF' switch in the lead wire assembly is in the 'ON' position. "I" is the 'ON' position and 'O' is the 'OFF' position.
Check for defective pressure switch. Make sure you are connected to a good 12 volt power source. Make sure any on/off switches are in the 'on' position. Remove the cap to the pressure switch. Pull both red wires off of their terminals, and touch the two ends together. If your pump runs when you do this, your pressure switch will need to be replaced.
Check the fuse.
Check for low voltage at the power supply.
Pump does not prime:
Check for air leaks in supply line.
Check for debris in the check valve assembly.
Check for defective check valve.
Check for clogged strainer/filter.
Check for cracks in the pump housing.
Check for empty product supply.
Low Pressure/Low Flow:
Check for leaks in the discharge line.
Check for restriction in the discharge line.
Check for debris in nozzle orifice.
Check for clogged strainer.
Check for proper voltage—try another 12-volt battery.
Use to pump bleach.
DON’T
Use to pump petroleum products such as diesel fuel, gasoline or kerosene
Leave your pump sit with spray mixture in it for extended periods
Use dirty or unfiltered water for spraying
Pulsating flow (surging):
Low flow may cause pump to surge.
Spray wand is adjusted for a small or fine spray pat- tern.
Slightly open bypass (if applicable) to overcome.
If needed, pressure switch may need to be adjusted— adjust a quarter turn at a time clockwise until surging stops.
Check for defective pressure switch.
Check for leaks in the discharge line.
Check for restriction in the discharge line.
Check for debris in nozzle orifice.
Discharge hose may be too long.
Check for clogged strainer.
Motor continues to run after discharge is shut off:
Check for empty product supply.
Check for open bypass valve. (if equipped)
Check for low voltage.
Check for leak in discharge line.
Check for defective pressure switch.
System has leaks.
Fuse blows:
Excessive voltage.
Improper adjustment of pressure switch.
Damaged or defective wiring harness.
Half-moon & counterweight are sticking.
Defective pressure switch.
Checking the Pressure Switch
:
If your motor is not running and you’ve checked the following: for loose wiring connections, 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 screw. This will expose the two red wires.
With the pump connected to a good 12 volt power source and everything on.
Slip the two red wires off the terminals and touch them together.
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 runs, but no pressure:
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.
