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.
