Watch for holes, rocks, or other hidden hazards. Always inspect area prior to operation. DO NOT operate near edge of drop-off or banks. DO NOT operate on steep slopes as overturn may result. Operate up and down (not across) intermediate slopes. Avoid sudden starts and stops. • Pick the most level possible route when transporting across fields. Avoid edges of ditches, gullies, and steep hillsides.

SPRAyER TIP ASSEMbLy INSTALLATION DEMCO booms are sold in 21, 30 and 40’ foot models. Tip placement will depend on the tip being used. When broadcast spraying with Flat Spray Tips, 20 inch tip spacing must be used and when spraying with Floodjet Tips, 40 inch spacing must be used.
CALIBRAtIoN 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.
