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 eachyear, whichever comes first.
NOTE:You can purchase a new spark arrester screen by
calling 1-800-4-MY-HOME (46g-4663).
If you useyour 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.

Air Coofing System
Overtime debris may accumulate in cylinder cooling fins and
cannot be observed without partial engine disassembly. For
this reason, we recommend you have a Sears or other
qualified service dealer clean the cooling system (A) per
recommended intervals (see Maintenance Schedule). Equally
important is to keeptop of engine free from debris. See
Generator Cleaning.
Check VaJve Clearance
Regular valve clearance check and adjustment will improve
performance and extend engine life. This procedure cannot
be done without partial engine disassembly and the use of
special tools. For this reason we recommend that you have a
Searsor other qualified service dealer check and adjust valve
clearance at recommended intervals.
