3.) Attach the trailer tongue (Item 8, figure B) to the sprayer frame (Item 7, figure B) aligning the holes and
using the pin and hair pin (Item 3, figure B).
Setup
Charging the Battery
1.) Obtain the battery charger (Item 27, figure B) and plug the charger into an AC wall outlet and the other
end into the charging port located on the sprayer.
2.) Allow the charger to charge the battery until the light on the charger turns from red to green. A green
light indicated the battery is fully charged. A red light indicates the batter needs charging. A
discharged battery could take as long as 24 hours to recharge.
3.) Never allow the battery to discharge completely. Doing so may damage or shorten battery life and void
warranty.
Testing
1.) Always test the sprayer with clean water prior to spraying with a chemical mixture. This will
allow the sprayer to be inspected for leaks and repaired before expensive chemicals are used.
Using the front Deflector Nozzle
1.) Four things must be considered before spraying with the boom.
1.) How much chemical must be mixed in the tank?

Refer to the chemical label to determine the chemical mixture
2.) Rate of spray (gallons per acre to be sprayed.

See the Tip Chart below to determine the gallons per acre. The chart will also show the
speed used when spraying.
3.) Speed traveled (M.P.H.) while spraying.

Refer to the Tip Chart and Speed Chart below for MPH.
Determine Gallons per Minute
Once you know how much you are going to spray then determine (from the tip chart) the spraying pressure
(PSI) and the spraying speed (MPH). The pressure is preset by the pump, typically between 30 to 35 psi,
but it will vary depending on the percentage of charge left in the battery. If precise chemical metering is
desired, then the battery should be fully charged and a flow rate should be measured at the nozzle. After
the battery is fully charged, obtain a bucket and place under the nozzle. Turn the valve on to begin
spraying water into the bucket while timing. Allow the sprayer to run for 1 minute and then turn off
sprayer. Measure the amount of water within the bucket to obtain the exact GPM of the pump and nozzle.
Determine MPH
Determining the proper walking speed can be done by marking off a length of 100 feet. The speed chart
indicates the number of seconds it takes to travel 100 feet.
