Clean Spark Arrester Screen

The engine exhaust muffler has a spark arrester screen. Inspect and clean the screen every 100 hours of operation or once each year, whichever comes first.

If you use your generator on any forest-covered, brush-covered, or grass-covered unimproved land, it must have a spark arrester. The spark arrester must be maintained in good condition by the owner/operator.
