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 1-800-4-MY-HOME
(469-4663).
The spark arrester must be serviced every 100 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.
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.
• Code of Federal Regulation (CFR) Title 36 Parks, Forests, and
Public Property require equipment powered by an internal
combustion engine to have a spark arrester, maintained in
effective working order, complying to USDA Forest service
standard 5100-1C or later revision. In the State of California a
spark arrester is required under section 4442 of the California
Public resources code. Other states may have similar laws.
