Trouble Shooting – Fast Tracking Problems
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 machine.
• Drive the machine at a constant speed in order to apply the required application volume as
determined by the nozzle selection chart.
• The machine should then be operated to empty the tank. Once the machine 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.
