Cleaning the Exhaust Port and Muffler

MAINTENANCE

CLEANING THE EXHAUST PORT AND MUFFLER

Depending on the type of fuel used, the type and amount of oil used, and/or your operating conditions, the exhaust port and muffler may become blocked with carbon deposits. If you notice a power loss with your gas powered tool, a quali- fied service technician will need to remove these deposits to restore performance.
