Static Test Instructions:
 | 1. Fill the sprayer with water.
 | 2. Park the sprayer on a level spot where the water sprayed  will not cause any problems.
 | 3. Bring the sprayer up to "spraying rpm".
 | 4. Open the nozzles and spray water for 10 minutes.
 | 5. Measure total amount of water sprayed in the 10 minute period.
 | 6. Divide the total gallons of water sprayed by 10 and that figure should equal the gallons per minute figure above ([NAME]).
 | 7. If the figure is close, but not correct, increase or decrease line pressure to raise or lower flow rate to the appropriate level.
 | 8. After adjusting the pressure, repeat steps 1-6.
