Spark Arrestor Muffler

•The spark arrestor muffler controls the exhaust noise and prevents hot, glowing particles of carbon from leaving the muffler.

•Make sure the spark arrestor screen is in good repair and properly seated in the muffler.

•Certain internal combustion engines operated on forest, brush, and/or grass-covered areas in the states of Washington, Oregon, Idaho, California, Minnesota, New Jersey and Maine, are required to be equipped with a spark arrestor.

This requirement also applies to all U.S. Forest Service lands. In some of these areas, the spark arrestor system must be certified per USDA Forest Service Regulation SAE J335.

Check with your local or state authorities for specific regulations in your area. Failure to follow these requirements is a violation of the law.
