The air filter is a critical component of your outdoor power equipment's engine system. Its primary function is to prevent airborne contaminants, such as dust, dirt, and debris, from entering the carburetor and engine cylinders. By filtering the incoming air, the Stens Air Filter 100-739 helps maintain a clean fuel-air mixture, which is essential for efficient combustion, consistent engine performance, and preventing premature wear of internal engine components.

Regular inspection and timely replacement of the air filter are vital for the longevity and performance of your Stihl equipment.

• Inspect the air filter every 10-25 operating hours or more frequently in dusty conditions.
• Check for visible dirt, debris, tears, or damage to the filter material.

Korvaus:

• Replace the air filter if it appears heavily soiled, clogged, or damaged. A clogged filter restricts airflow, leading to reduced engine power and increased fuel consumption.
• Even if it appears clean, replace the filter at least once per operating season or as recommended by your equipment's manufacturer.
• Do not attempt to clean heavily soiled paper or woven fabric filters, as this can damage the filter media and reduce its effectiveness. Replacement is the recommended action.

5. Vianmääritys

• Virheellinen asennus: Double-check that the filter is correctly oriented and fully seated within the air filter housing, and that the cover is securely fastened.
• Tukkeutunut suodatin: A severely clogged filter, even if new, can cause performance issues. Verify the filter is clean and free of obstructions.

If troubleshooting steps do not resolve the issue, consult your equipment's main service manual or contact a qualified service technician.
