OPERATION
BEFORE STARTING
It is important totesttheboomandspraygunwithplain
waterbeforeattemptingactualspraying.Thiswillenableyou
tocheckthesprayerforleaksandtosetthespraypattern
andnozzlepressure.Ifaleakshouldoccur,threadtape

USING THE SPRAYER
1. Determinetheapproximatesquarefootageofthearea
tobesprayed.Usethisamounttoestimatethenumber
of gallons that will be required, based on product
recommendations. This can help avoid unneeded
solutionleftinthetank.
2. Determinetheapplicationrate(gallonsper1,000sq.feet
orgallonsperacre)basedonthechemicalmanufacturers
recommendations.
3. Usethetipchartonpage9todeterminetheground
speedthatwillachievetherecommendedapplication
rate.
4. Todeterminethethrottlesettingforattainingthedesired
groundspeed,markoff100,200and300feetintervals.
Thespeedchartatthebottomofpage9indicatesthe

5. Add the chemical solution to the tank, following the
product instructions.
6. Drivetothestartingplaceforspraying.
