3. Installation Instructions

Always ensure the engine is turned off and cool before performing any maintenance. Refer to your equipment's specific service manual for detailed instructions on accessing the air filter housing.

1. Locate the Air Filter Housing: The air filter housing is typically located on the side of the engine. It may be secured with clips, screws, or wing nuts.
2. Open the Housing: Carefully open or remove the cover of the air filter housing.
3. Remove Old Filter: Gently pull out the old air filter and pre-filter. Note their orientation for correct installation of the new filter.
4. Clean Housing: Wipe the inside of the air filter housing with a clean, damp cloth to remove any dust or debris. Ensure no debris falls into the carburetor or engine intake.
5. Install New Pre-Filter: Slide the new foam pre-filter (the green component) over the new paper air filter. Ensure it fits snugly.

4. Maintenance

Regular inspection and replacement of your air filter are crucial for maintaining engine health and performance.

• Inspection: Inspect the air filter every 25 hours of operation or annually, whichever comes first. In dusty conditions, inspect more frequently.
• Cleaning (Pre-Filter Only): The foam pre-filter can be gently cleaned with warm, soapy water. Rinse thoroughly and allow it to air dry completely before re-installing. Do not attempt to clean the paper air filter; it should be replaced when dirty.
• Replacement: Replace the air filter and pre-filter every 100-200 hours of operation or annually, or sooner if it appears heavily soiled or damaged. A dirty air filter restricts airflow, leading to reduced engine power, increased fuel consumption, and potential engine damage.

If issues persist, consult a qualified service technician or your equipment's specific service manual.
