ASSEMBLY INSTRUCTIONS

Tools required:

1. Phillips Screwdriver
2. 1/2” End Wrenches
3. 9/16” End Wrenches

OPERATION

(Recommended to be used with a LG25DSS or similar 2.0 GPM or greater spot sprayer.)

Refer to your original spot sprayer operating instructions

Pressure may be regulated by opening or closing the valve located on the top of your tank. Refer to your original instructions, or see some common “Valve Operations” illustrated in this manual.

Regularly inspect the suction supply screen on the inside of the tank. Flush with water to clear any accumulated debris.

CALIBRATION

Chemical product labels may show application rates in gallons per acre, gallons per 1000 square feet, or gallons per 100 square feet. The tip chart for your sprayer shows all three rates for your convenience.

After determining how much mixed solution you are going to spray for your job, select the spraying pressure (PSI) and spraying speed (MPH) needed.

Current weather and terrain conditions must be considered when setting up the sprayer. Do not spray on windy days (over 11 MPH), and protective clothing must be worn with some products.

Be sure to read the chemical label carefully

To determine the ground speed of your sprayer, measure and mark driving distances of 100, 200, or 300 feet. Our speed chart indicates the number of seconds needed to travel these distances. Set your throttle, and with a rolling start, drive the measured distance of your choice. Adjust your throttle until you can match the number of driving seconds needed. Mark the throttle setting and note the gear range so you can use them while spraying

Add water and chemicals in the proper amounts in the spray tank and drive to your starting point. When you are ready to spray, turn your boom control valve to the “ON” position. Once the pump is turned on, the unit will begin spraying. The system pressure will decrease slightly when you see solution flowing from the spray nozzles. This is normal, the pressure will return as before when you turn the control valve to the “OFF” position.

You will find optimal spraying in the 20 to 30 PSI range.

AFTER SPRAYING

After use, fill the sprayer part way with water. Start the sprayer and allow clear water to be pumped through the plumbing system and out through the spray nozzles

Refill the tank about half full with plain water and use a chemical neutralizer such as Nutra-Sol® or equivalent and repeat cleaning instructions. Flush the entire sprayer with the neutralizing agent. Follow the chemical manufacturer’s disposal instructions of all wash or rinsing water.

Remove tips and screens from the boom. Wash tips thoroughly with water or cleaning solution (appropriate for chemical used). Blow out orifice, clean and dry. If orifice remains clogged clean it with a fine bristle (not wire) brush, or with a toothpick. Do not damage the orifice. Water rinse and dry tips before storing.

WINTER STORAGE

Drain all water and chemical out of sprayer, paying special attention to pump and valves. These items are especially prone to damage from chemicals and freezing weather

The sprayer should be winterized before storage by pumping a solution of RV antifreeze through the entire plumbing.
Proper care and maintenance will prolong the life of the sprayer.
