Add the proper amount of chemical to the tank (check the chemical label for proper ratio of chemical). Stir mixture in tank with a clean utensil (like a paint stirrer). The tank will hold the 4-gallon (15.1L) capacity plus the chemical.

It is not necessary to completely fill the sprayer tank with each use. You can fill the tank with only the amount needed for each application.

Always follow the manufacturer’s instructions included on their product label.

OPERATING THE SPRAYER

  • OPERATING THE SPRAYER
  • Plug in charged battery
  • Turn switch to on position
  • Spray liquid back into tank to prime pump
  • Close shut-off. Pump should stop running.
  • Replace cap & begin spraying.

POWDER-BASED CHEMICALS – (Not recommended for use with this model).

Powder-based chemicals (powder mixed with liquids to make the spraying agent) are usually abrasive and can cause wear. When you use a powder-based chemical in your sprayer, make sure it is thoroughly dissolved in the liquid solution. Thoroughly clean and flush the sprayer with water to extend the life of the sprayer’s parts.

When finished spraying turn switch to off position.

Remove and re-charge battery.

Note: Unit is equipped with a battery protection circuit. If sprayer abruptly stops after spraying for an extended period of time, the battery may require charging.

CLEANING

  • Always empty the sprayer and clean the tank thoroughly after each use.

CLEANING FILTERS

  • There are two (2) filters in your sprayer that need to be cleaned regularly. The first filter is located in the body of the shut off assembly. The shut off assembly is the handle with the red grip and trigger that you squeeze to create the spray. The second filter is in the tank, next to the pump.

Shut Off Assembly Filter

  • Unthread the shut off assembly from the hose. In the body of the handle is a white filter.
  • Remove the filter and soak in warm soapy water to clean any debris or chemical residue that may be present.
  • Once you have cleaned this filter you will reattach the handle to the hose.

In Tank Filter

  • Looking inside of your tank from above you will see a black stick with a finger hole. You can pull this stick straight up.
  • Soak the filter in warm soapy water to clean up any debris or chemical residue that may be present.
  • Once you have cleaned this filter, slide the filter back into place alongside of the pump.

Other Cleaning Hints:

  • Improper spray distribution usually means the nozzle is clogged, remove the nozzle and clean it.
  • Soap can be added to the water to clean the tank.
  • Do not use strong cleaning agents or abrasives.
  • If you use a chemical agent to clean the tank, follow the manufacturer’s recommendations for the disposal of the waste water.
  • Follow the chemical manufacturers instructions for clean up.

TROUBLE SHOOTING NOTES

CHECKING THE WIRE CONNECTIONS:

  • Make sure that your tank is empty and not pressurized.
  • Loosen the bolt in the front of the sprayer.
  • Slowly pull down the switch housing.
  • You will see wires and you will want to make sure that the wires are connected near the pump and at the switch.
  • Once you have verified that the wires are properly connected you will reattach the housing to the tank in the same manner you removed the housing.

PRIMING THE PUMP ( First time use or after long storage)

  • Fill your tank at least ¾ of the way full with water. Make sure that the pump cylinder is completely submerged in water.
  • Let the water sit in the tank for a few hours.
  • Once your unit has sat for a period of time you can turn the switch to the on position. The l indicates the on position, the 0 indicates the off position.
  • With the switch turned on, place a rubber band around the trigger of the shut off assembly to hold the trigger open, as if you were spraying.
  • Let your unit run for @12-15 minutes. You may not receive a spray right away as your pump may run but may not build pressure. This is acceptable and part of the priming steps.
  • You should receive a strong stream at the 12-15 minute mark.
  • Your unit is now cleaned and primed and ready for use.
