SPRAYER
GENERAL SPRAYING INFORMATION
Application Tips
Always use clean, filtered water in the sprayer tank.
Check the flow rate from all nozzles using the capacity calibration technique. See Calibration section for
tables and instructions. Adjust the sprayer pressure to get the proper flow rate.

Diaphragm check valves close at 15 psi to prevent excessive dripping.

Calibration
As a tip wears, the spray pattern distorts, output volumes usually increase, and the droplet characteristics
change. Recalibration may correct for output changes, but cannot correct for spray pattern changes or
the drop size generated. To calibrate and operate the sprayer at the desired pressure. Collect the output
from each nozzle for 60 seconds, using an accurate measuring cup. Record the output from each nozzle.
Replace nozzles that are more than 5% above or below the average reading, or have a visibly distorted
pattern.
Actual sprayer speed, as determined from the following tables, will differ from the sprayer speedometer
readings because of wheel slippage. Run a speed test in the field to be sprayed, and have the sprayer
tank half full. The sprayer must be at full speed before starting the test run. To determine the speed
discrepancy, mark off a distance as found on one of the tables. Run the power unit over this distance,
carefully noting the speedometer reading and recording the time to cover the distance. The actual speed
traveled can be found for the specific distance and time to travel, using the table.
