Cooling System Cleaning; Spark Arrestor Muffler - Echo CS-355T Operator's Manual

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 the recoil starter and the air guide plate.
2. Use compressed air or wooden
tool to remove dirt and dust
from between fins to let cooling
air pass easily.
3. Clean the periphery of the
ignition coil and the flywheel
magneto.
4. Assemble the components in
reverse order.

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.
