Filling:
Mix the spray formula and the proper volume of water in a separate container. Pour the mix through the filter basket in the tank opening. This keeps debris from entering sprayer. Note: To fill the sprayer to its full 4 gallon capacity, set the pressure control valve to the 3 or 4 setting. (See Above: “Regulating the Pressure.”) Add 2 or 3 gallons of spray formula mix. Pump the sprayer handle to prime the pump and fill the pressure cylinder. The volume of liquid in formula mix tank will appear to decrease as the pressure cylinder is filled. Liquid will flow through the top of the pressure regulator when the cylinder is completely full. Add the remaining formula mix to the tank. Remember that it’s not necessary to completely fill the sprayer tank each time. Mix only the amount needed to get the job done.
Operating:
Prime the pump with rapid pump strokes. When you feel very firm resistance, the pressure chamber is filling with liquid. With repeated piston strokes, the air in the pressure chamber is slowly compressed. By pressing the hand lever, the valve opens, and liquid is forced through the nozzle. The shut-off valve has a retaining clip which keeps the valve in the “OPEN” position for continuous operation. Pump using the end of the pump handle, as it is less fatiguing. The volume of liquid delivered varies with the working pressure which should be as high as needed to ensure an adequate spray pattern for each individual application.
NOTE: Should the pressure drop very quickly, drain the tank completely and pump without liquid. By this procedure, the air chamber is refilled with the required volume of air. It is advisable to pump the tank completely empty from time to time.
Cleaning:
After spraying, clean the tank thoroughly. If some spray liquid is left inside, drain tank completely.
Pumping causes air to be taken in and the remaining liquid to be discharged. Pump until liquid and air are coming out through the nozzle.
Refill tank with a few quarts of clean water and pump the water out as explained above (if necessary, repeat this procedure several times).
If the shut-off valve is removed, the pump can be flushed quickly. Improper spray distribution is the result of a clogged nozzle, which is easily removed and cleaned.
Soap and water may also be used to clean tank.
Do not use aggressive cleaning agents or abrasives.
Follow the recommendations of the chemical manufacturer for disposal of waste water and chemicals.
Activated charcoal in liquid or other form may be used to absorb chemicals in tanks or spills.
