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.

SPARK ARRESTOR

The spark arrestor must be cleaned or replaced every 25 hours or yearly to ensure proper performance of your product. For the location of the spark arrestor and specific cleaning in- structions, contact your nearest authorized service center.

For proper performance and long life, keep air filter clean.

FUEL CAP

WARNING:

A leaking fuel cap is a fire hazard and must be replaced immediately.

The fuel cap contains a non-serviceable filter and a check valve. A clogged fuel filter will cause poor engine perfor- mance. If performance improves when the fuel cap is loos- ened, check valve may be faulty or filter clogged. Replace fuel cap if required.
