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, contact your local Sears service center.
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 spark
arrester.
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.
• 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 14). Equally important is to keep top
of engine free from debris. See "Clean Debris".
Keep areas within heavy line clear of debris.
Clean Combustion Chamber
We recommend you have an authorized Sears service
dealer remove combustion deposits from the cylinder,
cylinder head, top of piston and around valves per
recommended intervals (see "Maintenance Schedule"
on page 14).
