How do i replace the spring on weedeater?

To replace the spring on a weed eater, first, ensure the tool is unplugged or the battery is removed for safety. Disassemble the weed eater by removing the spool cover and line, then locate the spring, which is usually found in the spool assembly. Remove the old spring and replace it with a new one, ensuring it is properly seated in place. Reassemble the weed eater by putting the spool cover back on and reloading the line before testing the tool.
