I--
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
i
on the engine with the air cleanerlfilter off.
Notice; If the air cleanerlfilter 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.
