Spark Arrester Service
Your engine is not factory-equipped with a spark arrester. In
some areas, it is illegal to operate an engine without a spark
arrester. Checklocal laws and regulations. A spark arrester is
availablefrom your nearest Sears service center. If you need
to order a spark arrester, please call 1-SOO-4-MY-HOME
(46g-4663).
The spark arrester must be serviced every 50 hours to keep it
functioning as designed.
If the engine has been running, the muffler will be very hot.
Allow the muffler to cool before servicing the spark arrester.

cannot be observed without partial engine disassembly. For
this reason, we recommend you have a qualified Sears
service dealer clean the cooling system per recommended
intervals (see MaintenanceSchedule). Equally important is to

engine is stopped and water is disconnected,
which can cause injury.
