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.
Pulsating flow (surging):
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 or dirty check valve.
Check for defective pressure switch.

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 (fine mist)
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.
Maintenance During/After Spraying
Periodically check and clean the strainer on your intake tube.
Proper care and maintenance will prolong the life of your sprayer.
After use, fill the sprayer half way with clean water. Start the pump and allow the water to pump through the entire plumbing system and handgun nozzle. 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). Turn pump on and circulate through system for 15 minutes and then spray out through the 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 nozzle and soak in warm soapy water. Clean with a soft bristled brush if necessary.
Winter Storage
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.
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.
