3. Clean the engine air cleaner/filter housing.
4. Inspect or replace the engine air cleaner/filter.
Make sure that the filter fits properly into
the housing.
5. Reinstall the cover and fasten the
retaining clips.
{ 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 your engine, which will
damage it. Always have the air cleaner/filter in
place when you are driving.
