How do you remove the head on a WEEDEATER featherlight?

To remove the head on a WEEDEATER Featherlight, first ensure the trimmer is turned off and the spark plug is disconnected for safety. Hold the spool firmly and rotate the head counterclockwise to unscrew it. If the head is stuck, you may need to tap it lightly with a rubber mallet or use pliers for better grip. Once loosened, you can pull the head off the shaft.
