Why Replace Your Air Filter?
A clogged or worn air filter restricts airflow, causes the engine to run rich, increases fuel consumption, and can lead to hard starting or poor performance. Replacing it regularly — especially after heavy use or in dusty conditions — keeps your trimmer starting easily and running smoothly season after season.
