2. Determining Nozzle Size/Using Calibration Chart
The spray nozzles on your sprayer are color-coded to match up with the calibration chart. After you have determined your nozzle
size, you need to look at the calibration chart. Using your calculated speed, nozzle size, and desired gallons per acre (GPA), find the
pressure (psi) necessary to achieve your GPA. It is important to note that lower pressure settings will result in less spray drift.
Example: Assume you have found your calculated speed to be 5 MPH, your nozzles are lavender (110025), and you want to spray
13 GPA. Upon looking at the chart, you find that you should set the sprayer's pressure at about 29 psi in order to apply 13 GPA.

Winterizing your Sprayer
It is essential that you winterize your sprayer to avoid damage and to allow for optimal performance. The winterization process
should be undertaken before freezing conditions and/or after each season of use. Failure to winterize your sprayer will void the
manufacturer’s warranty.
Note: Please reference your sprayer owners manual for proper winterizing.
