Operating the engine with the air cleaner/filter off can cause you or othersWARNING
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.
