SPRAYER CALIBRATION PROCEDURES NOTE: To avoid wind drift, use lower pressure and higher spray volume. Guidelines For Sprayer Calibration Before calibrating your sprayer, first determine whether each nozzle is delivering at a uniform rate. Place quart jars under all nozzles and watch as they fill up. The level should rise uniformly and take the same time (within 10%) for all nozzles to fill the jars. Replace any nozzle showing a discharge rate different from the others. Calibrating the Sprayer 1. 2. 3. 4.

SPRAYER CHECKLIST: Downtime caused by field breakdowns is costly and time consuming. Many breakdowns can be eliminated by periodic equipment maintenance. By spending time reviewing this checklist before seasonal spraying application time and following proper after-season care, you can save time and money later. ! WARNING: To Prevent Serious Injury Or Death ï Keep hands, feet, and loose clothing away from rotating parts.
