If the flow meter fails to give accurate readings, the following actions should be taken:
• Adjust the spraying pressure by putting the flow control switch into manual and using the increase decrease
switch to adjust to the desired pressure as shown on the pressure gauge on the sprayer.
• Drive the sprayer at a constant speed in order to apply the required application volume as determined by
the nozzle selection chart.
• The sprayer should then be operated to empty the tank. Once the sprayer is empty of chemical, partially fill
the tank with fresh water so that test can be performed in order to correct the problem. Repair or replace
the flow meter as soon as possible.
