John Deere 632 Operator's Manual

To calibrate the John Deere 632 Sprayer, follow these steps: 1) Check the nozzle type and ensure they are clean. 2) Fill the tank with water and engage the spray system. 3) Measure the output from each nozzle for consistency. 4) Adjust pressure settings as needed to achieve uniform spray output.
Uneven spray patterns can be caused by clogged nozzles or incorrect pressure settings. Check and clean all nozzles, ensuring they are not worn out. Verify that the pressure is set according to the manufacturer's specifications.
Regular maintenance for the pump includes checking for leaks, ensuring seals are intact, lubricating moving parts, and replacing the diaphragm or piston as needed. Regularly inspect the pump for any signs of wear or damage.
Filters should be inspected before each use and replaced if they show signs of clogging or damage. As a best practice, replace the filters at least once every spraying season to ensure optimal performance.
For herbicide applications, use flat fan nozzles designed for even coverage. Ensure that the nozzles are compatible with the viscosity and type of herbicides used.
To prevent corrosion, always rinse the tank thoroughly with clean water after each use. Use a neutralizing solution if aggressive chemicals have been used, and store the sprayer in a dry environment.
If the GPS guidance system is not functioning, check the power connections first. Ensure that the GPS antenna is correctly installed and unobstructed. Update the GPS software and maps as needed.
To winterize the sprayer, thoroughly clean and drain all water from the system to prevent freezing. Add antifreeze to the pump and hoses, and store the sprayer in a sheltered area.
Pressure fluctuations can be caused by air leaks in the suction line, damaged pump seals, or clogged filters. Inspect all connections and components for leaks or blockages and replace parts as necessary.
To improve efficiency, regularly maintain the sprayer by cleaning nozzles and filters, calibrate the system frequently, and use the appropriate settings for different applications. Utilize GPS guidance to minimize overlap and ensure accurate application.
