NOTE: You can purchase a new spark plug by calling

Spark Attester 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
center. If you need to order a spark attester, please call
1-800-4-1_IY-HOME (469-4663}.
The spark arrester must be serviced every 50 hours to
keep it functioning as designed.
WARNING
DO NOT touch hot surfaces and avoid hot exhaust gases.
Allow equipment to coo! before touching.
Keep at least 5 ft. (152 cm) 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 attester is
required under section 4442 of the California Public
resources code. Other states may have similar laws.
If the engine has been running, the muffler will be very
hot. Allow the muffler to cool before servicing the
spark arrester.
• Remove spark attester 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 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".
