Operating the engine with the air cleaner 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 off.
1 NOTICE:
If the air cleaner 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 in place when you’re driving.
