Inspect the filter regularly for excessive dirt, damaged media, hardened seals, or restricted airflow. Replace it according to the generator operator’s manual. Different KY and KYD configurations have different service intervals, and operation in dusty conditions may require more frequent replacement.

Turn off the generator and allow it to cool before servicing. Clean loose debris from around the air-filter housing before removing the old filter, and ensure the replacement is seated and sealed correctly.
