Service Air Cleaner
Your engine will not run properly and may be
damaged if you run it with a dirty air cleaner.
Service the air cleaner once every 25 hours of
operation or once each year, whichever comes first.
Service more often if operating under dirty or dusty
conditions. Replacements are available at your local
Sears service center.
To service the air cleaner, follow these steps:
1. Loosen two screws and lift off cover.

Spark Arrester Service
Your engine is not factory-equipped with a spark attester.
In some areas, it is illegal to operate an engine without a
spark attester. 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(4694663).
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.
• Code of Federal Regulation (CFN) 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.
• Remove spark arrester screen for cleaning and
inspection.
• Replace if screen is damaged.
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 17). Equally
important is to keep top of engine free from debris.
See "Clean Debris".
