Air cleaner element WARNING Do not operate the engine with the air cleaner element removed. The air cleaner element not only filters in- take air but also stops flames if the engine backfires. If the air cleaner element is not installed when the engine backfires, you could be burned. CAUTION When replacing the air cleaner ele- ment, use a genuine SUBARU air cleaner element. If it is not used, there is the possibility of causing a negative effect to the engine. The air cleaner element functions as a filter screen. When the element is perforated or removed, engine wear will be excessive and engine life shortened. It is not necessary to clean or wash the air cleaner element.
