USING THE SPRAYER

1. Determine the application rate (gallons per 1,000

sq. feet or gallonsper acre) based on the chemical

manufacturersrecommendations.Usethisratetohelp

select the pressure setting and tractor speed in the

following instructions.

2. Determinetheapproximatesquarefootageoftheareato

besprayedandestimatethenumberofgallonsrequired.

Thiscanhelpavoidunneededsolutionleftinthetank.

3. Determinetheappropriatespeedatwhichtotravel,based

onthechosenpressuresettingandtherecommended

applicationrate.Usethetipchartonpage9.

4. To determine the throttle setting for attaining the

appropriate speed, mark off 100, 200 and 300 feet

intervals. The speed chart at the bottom of page 9

indicatesthenumberofsecondsittakestotravelthese

andgearsettings needed, markthethrottle location

sothatyoucaneasilyresumethesamespeedafter

stopping.

5. Settheoperatingpressure.Spraywithplainwaterto
