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
distances.Setthethrottleand,witharunningstart,travel
thedistancesinthenumberofsecondsindicatedby
thespeedchart.Onceyouhavedeterminedthethrottle
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

tothetipchartonpage9.
6. Add the chemical solution to the tank, following the
product instructions.
7. Drivetothestartingplaceforspraying.Settheboom
