To calibrate the John Deere 4630 Sprayer, ensure the tank is filled with water, select the correct nozzle type, and adjust the pressure settings. Use the onboard display to input calibration settings and perform a test run to verify accuracy.
First, check for any leaks in hoses or connections. Ensure the pump is functioning correctly and the pressure regulator is set appropriately. If the issue persists, inspect the filters for clogs and clean or replace them as necessary.
Regular maintenance should be performed after every 50 hours of operation, including checking fluid levels, cleaning filters, inspecting nozzles, and lubricating moving parts. An annual comprehensive check should also be done before the spraying season.
To winterize, first, drain all water from the system. Add antifreeze to the pump and lines, clean the tank thoroughly, and store the sprayer in a dry, sheltered location. Inspect all components for wear and tear before storage.
Uneven spray patterns can be caused by clogged nozzles, incorrect nozzle selection, or pressure inconsistencies. Inspect and clean nozzles, ensure they are of the correct type, and check the pressure settings to troubleshoot the problem.
Verify that the GPS antenna is unobstructed and connected properly. Check the display settings for any configuration errors and ensure that the firmware is up to date. Reset the system if necessary.
To clean the filters, first relieve the system pressure and remove the filter housing. Rinse the filter element with clean water and inspect for damage. Replace if necessary, then reassemble the housing.
The John Deere 4630 Sprayer is compatible with a variety of nozzle types, including flat fan, air induction, and turbo teejet nozzles. Select a nozzle based on the application requirements and desired spray pattern.
Regular maintenance, such as keeping the pump lubricated, avoiding running the pump dry, and ensuring clean water use can extend its life. Also, check for leaks and replace worn-out seals promptly.
Common error codes include E01 (pressure sensor fault), E02 (GPS signal loss), and E03 (pump motor issue). Refer to the user manual for detailed troubleshooting steps for each code.
