Inspect Muffler and Spark Arrester
Inspect the muffler for cracks, corrosion, or other damage.
Remove the spark arrester, if equipped, and inspect for
damage or carbon blockage. If replacement parts are required,
make sure to use only original equipment replacement parts.
WARNING: Contact with muffler area can result in
serious burns.
Exhaust heat/gases can ignite
combustibles, structures or damage
fuel tank causing a fire.
• DO NOT touch hot parts and AVOID hot exhaust gases.
• Allow equipment to cool before touching.
• Keep at least 5 feet (152 cm) of clearance on all sides of
pressure washer including overhead.
• It is a violation of California Public Resource Code, Section
4442, to use or operate the engine on any forest-covered,
brush-covered, or grass-covered land unless the exhaust
system is equipped with a spark arrester, as defined in Section
4442, maintained in effective working order. Other states or
federal jurisdictions may have similar laws.
Contact the original equipment manufacturer, retailer, or dealer
to obtain a spark arrester designed for the exhaust system
installed on this engine.
• Replacement parts must be the same and installed in the same
position as the original parts.
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 qualified Sears
service dealer clean the cooling system (F) per
recommended intervals (see Maintenance Schedule). Equally
important is to keep top of engine free from debris. See
Clean Debris.
