Spark Attester
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
dealer. If you need to order a spark arrester, please call
1-800-4-MY-HOME (469-4663).
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.
WARNING
DO NOT touch hot surfaces
and avoid hot exhaust
gases.
Allow
equipment
to cool before
touching.
Keep at least 5 ft. (152 cm) clearance
on all sides
of
pressure
washer
including
overhead.

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 a Sears or other qualified service dealer clean
the cooling system per recommended intervals (see
"Maintenance Schedule" on page 16). Equally
important is to keep top of engine free from debris.
See "Clean Debris".
Clean Combustion
Chamber
We recommend you have a Sears or other qualified
service dealer remove combustion deposits from the
cylinder, cylinder head, top of piston and around valves
per recommended intervals (see "Maintenance
Schedule" on page 16).
6.
Install spark plug, tighten securely.
NOTE: You can purchase a new spark plug by calling
1-800-4-MY-HOME (469-4663).
