How to Inspect the Engine Air Cleaner/Filter

Refer to the Part A: Scheduled Maintenance Services in this book to determine when to replace the air filter.

Caution: Operating the engine with the air cleaner/filter off can cause you or others to be burned. The air cleaner not only cleans the air; it helps to stop flames if the engine backfires. If it is not there and the engine backfires, you could be burned. Do not drive with it off, and be careful working on the engine with the air cleaner/filter off.

Notice: If the air cleaner/filter is off, a backfire can cause a damaging engine fire. And, dirt can easily get into the engine, which will damage it. Always have the air cleaner/filter in place when you are driving.

If you want to replace the engine air cleaner/filter yourself, use the following steps.

  4. Pull the air cleaner/filter box cover out and remove the air filter element from the air filter box. If the element is dirty, you should replace it. If the element is only dusty, it may be cleaned by blowing compressed air through it from the clean side. Make sure you are away from your engine compartment when cleaning the air filter with compressed air.
