Inspect Spark Arrester Screen
The engine exhaust muffler has a spark arrester screen. Inspect the screen every 50 hours of operation or once each year, whichever comes first..The spark arrester must be maintained in good condition by the owner/operator.
Inspect the spark arrester as follows:
•Using a powerful flashlight, examine the circular screen installed in the end of the exhaust port.There should be no rips or tears in the screen.There should be little or no accumulated soot on the screen.
•Replace the screen if torn, perforated or otherwise damaged. Do Not use a defective screen. Consult Generac Technical Services for assistance in changing the screen.
•If screen is not damaged, it may be cleaned in place with a gentle brushing from a wire brush or bottle brush.
CAUTION! The engine speed was properly adjusted at the factory and should require no additional adjustment. Do Not attempt to change engine speed. If you believe the engine is running too fast or too slow, contact the factory for assistance. CHANGING THE ENGINE GOVERNED SPEED WILL VOID THE ENGINE WARRANTY AND WILL ADVERSELY AFFECT SYSTEM OPERATION.
To assure smooth operation, keep governor linkage, springs and controls free of debris.
