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 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
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 14). Equally
important is to keep top of engine free from debris.
See "Clean Debris".
