HAKE WELL BEFORE EACH USE. For best results, clear debris away from the foundation of your home and cut back overgrown vegetation before using. Connect a garden hose to the nozzle, tighten and check to ensure both the front and back dial on the nozzle are in the vertical "OFF” position. To begin, aim the nozzle toward the treatment area, turn the back dial counter—clockwise (to the left) to start the flow of water. Then turn the front dial counter—clockwise (to the left) to start the flow of mixed product. To STOP spraying mixed product, turn the front dial clockwise (to the right) to the vertical “OFF” position.
