First, ensure the trimmer is turned off and cool. Locate the flange nut on the trimmer head. Use a wrench to loosen and remove the old nut, then replace it with a new one, tightening it securely. Ensure the trimmer head is properly aligned before use.
Check for signs of wear such as rust or rounding on the edges. If the trimmer head feels loose or wobbly during operation, the flange nut may be worn and require replacement to ensure safe operation.
