  3. On a level surface, fill your sprayer with water to the full mark.
  4. If your sprayer has a pressure gauge, turn on the pump and set the pressure to 30 PSI. (If you are unable to adjust the pressure, proceed with the factory settings.)

When to the end of the test run, turn off the sprayer pump and park on a level surface. (This spraying speed must be the same every time you spray so be sure to remember it.)
