Combustible debris, such as leaves, grass, brush, etc. can catch fire.

•Allow muffler, engine cylinder fins, and radiator to cool before touching.

•Remove accumulated debris from muffler area and cylinder fins.

Other States and Federal jurisdictions may have similar laws. Contact the original equipment manufacturer, retailer, or dealer to obtain a spark arrester designed for the exhaust system installed on this engine.
