5. Vedligeholdelse
Regular maintenance of your air filter is crucial for engine health and efficiency. The inner air filter typically serves as a safety filter and is not usually cleaned. It should be replaced if it appears dirty or damaged, or if the outer filter has been replaced multiple times.
- Inspektion: Periodically inspect the inner air filter for signs of dirt, damage, or tears.
- Udskiftning: Replace the inner air filter whenever the outer air filter is replaced for the second or third time, or immediately if the inner filter shows any signs of contamination or damage.
- Rensning: Do not attempt to clean the inner air filter. Cleaning can damage the filter media and reduce its effectiveness.

Hvis du oplever problemer relateret til luftfiltrering, bør du overveje følgende:
- Reduceret motorydelse: A clogged air filter can restrict airflow, leading to a loss of engine power, rough idling, or misfires. Inspect and replace both inner and outer filters if necessary.
- Øget brændstofforbrug: An engine struggling for air due to a dirty filter will consume more fuel.
- Sort røg fra udstødning: This can indicate incomplete combustion due to insufficient air, often caused by a severely clogged air filter.
- Usædvanlige motorlyde: A damaged air filter or housing can sometimes lead to whistling or sucking sounds.
If problems persist after inspecting and replacing the air filter, consult a qualified technician.
