Refer to the Maintenance Schedule to determine when to replace the air filter. See "Owner Checks and Services" in the Index. 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 stops flame if the engine backfires. If it isn't there, and the engine backfires, you could be burned. Don't drive with it off, and be careful working on the engine with the air cleaner/filter off. 1. To remove the engine/air cleaner filter, loosen the screws on the housing cover. 2. Then lift the cover upward and remove the filter from the housing. Care should be taken to dislodge as little dirt as possible. 3. Clean the filter sealing surface and the filter housing. 4. Install the new filter. 5. Reinstall the housing cover. NOTICE: If the air cleaner/filter is off, a backfire can cause a damaging engine fire. And, dirt can easily get into your engine, which will damage it. Always have the air cleaner/filter in place when you're driving. 6-22
