Regular inspection and replacement of the pre-filter are crucial for maintaining engine health and performance. The Stens 100-446 Pre-Filter is designed to be disposable.

- Wymiana: Replace the pre-filter when it appears dirty, clogged, or damaged. A dirty pre-filter can restrict airflow, leading to reduced engine power and increased fuel consumption.
- Cleaning (Not Recommended): As this is a disposable pre-filter, cleaning is generally not recommended. Attempting to clean it may compromise its filtration effectiveness. Always replace with a new pre-filter.
5. Rozwiązywanie Problemów
If you experience engine performance issues, a clogged pre-filter could be a contributing factor.
- Zmniejszona moc silnika: If the engine seems to lack power or struggles under load, check the pre-filter. A heavily soiled pre-filter restricts air intake.
- Zwiększone zużycie paliwa: A restricted air filter system can cause the engine to run rich, leading to higher fuel consumption.
- Wypadanie zapłonów lub nierówna praca silnika na biegu jałowym: While less common for pre-filters alone, severe air restriction can affect combustion.
Rozwiązanie: In most cases, replacing a dirty or clogged pre-filter (and main air filter if also dirty) will resolve these issues related to air intake.
