WARNING
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. Use caution when working on the engine and do not drive with
the air cleaner/filter off.
Notice: If the air cleaner/filter is off, dirt can easily get into the engine, which could damage it.
Always have the air cleaner/filter in place when you are driving.
