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.
