Sprayer Cal ibration Steps 



1. Clean out the sprayer tank and booms. 



2. Remove and clean all screens and nozzle tips. 



3. Check the tips to see that they are all similar. 



k. Check the pressure gauge to see that it is operating. Screw in a new 

 gauge to check the old one. 



5. Fill the sprayer about half full with clean water. While standing, 

 start the pump and turn on the sprayer. Catch and measure the output 

 of every nozzle tip by holding the measuring cup under each nozzle tip 

 for 15 seconds. Output should not vary by over + 5^ among nozzles. 

 Replace inaccurate tips. 



6. Set the pressure appropriate for the pesticide. Read the product label 

 for directions. 



7. Select the tractor speed in MPH or the gear and RPM you intend to use 

 when spraying. 



8. Measure off the appropriate distance based on nozzle spacing from the 

 table below. Measure with a tape measure and put flags or stakes at 

 each end. 



9. Catch the output of one nozzle tip as you travel over the measured 

 distance. Use a running start and travel at the speed you intend to 

 use when spraying. Turn on the entire boom if you are broadcast 

 spraying, not just one or two sections. 



10. Measure the spray output in ounces.
