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. Check local laws and
regulations. A spark arrester is available from your
nearest Sears service center. If you need to order a
spark arrester, please call 1-800-366-PART.

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 spark
arrester.

Air Cooling System

Over time debris may accumulate in cylinder cooling

fins and cannot be observed without partial engine
disassembly. For this reason, we recommend you have
an authorized Sears service dealer clean the cooling
system per recommended intervals (see “Maintenance

Schedule” on page 13). Equally important is to keep top
of engine free from debris. See “Clean Debris”.

Keep areas within heavy line clear of debris.

Clean Combustion Chamber

We recommend you have an authorized Sears service
dealer remove combustion deposits from the cylinder,
cylinder head, top of piston and around valves per
recommended intervals (see “Maintenance Schedule”
on page 13).
