Cooling System Cleaning

• Check periodically.

• Clogged fins will result in poor

engine cooling.

Remove cylinder cover and

starter.

Use compressed air or wooden

tool to remove dirt and dust

from between fins to let cooling

air pass easily.

• The spark arrester muffler controls the exhaust noise and prevents hot,

glowing particles of carbon from leaving the muffler.

• Make sure the spark arrester 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 arrester.

This requirement also applies to all U.S. Forest Service lands. In some of

these areas, the spark arrester 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.
