Cooling System Cleaning, Spark Arrestor Muffler

CS-450P	MAINTENANCE

Some tree sap and resins are corrosive. Thoroughly wash the guide bar and sprocket areas after each use, then coat metal parts with light oil.

Cooling System Cleaning

•Check periodically.

•Clogged fins will result in poor engine cooling.

1.Remove air cleaner cover, cylinder cover, and starter.

2.Use compressed air or wooden tool to remove dirt and dust from between fins to let cooling air pass easily.

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.
