Service Spark Plug
Service the spark plug every 100 hours of operation or
yearly, whichever occurs first.
1. Clean area around spark plug.
2. Remove and inspect spark plug.
3. Replace spark plug if electrodes are worn, or if
insulator is cracked or chipped.
4. For replacement use either the standard resistor
spark plug, Champion RC12YC or the long life
platinum spark plug, Champion RC12PYP.
5. Check electrode gap with wire feeler gauge and
set gap at 0.020 inches (0.50mm), if necessary.
6. Install spark plug, tighten securely.
NOTE: You can purchase a new spark plug by calling
1-800-4-MY-HOME (469-4663).
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 50 hours to
keep it functioning as designed.
WARNING
Running engines produce heat.
Temperature of muffler and nearby areas
can reach or exceed 150°F (65°C).
Severe burns can occur on contact.
Exhaust heat/gases can ignite combustibles,
structures or damage fuel tank causing a fire.
• 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 (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.
If the engine has been running, the muffler will be very
hot. Allow the muffler to cool before servicing the
spark arrester.
•
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 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".
