Carburetor
if you think your carburetor needs adjusting, see your
nearest Sears service center. Engine performance
may be affected at altitudes above 3000 feet. For
operation at higher elevations, contact your nearest
Sears service center.
Spark Attester Service
Your engine is not factory-equipped with a spark
attester. In some areas, it is iWegalto operate an
engine without a spark arrester. Check local laws and
regulations. A spark attester is available from your
nearest Sears service center. If you need to order a
spark arrester, please call 1-800-366-PART.
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.
• Remove spark attester screen for cleaning and
inspection.
• Replace if screen is damaged.
WARNING

Allow equipment to coo! before touching.
The pressure washer must be at least 5 feet from
structures having combustible walls and/or other
combustible materials,
Keep at least 3 feet of clearance on all sides of pressure
washer for adequate cooling, maintenance and servicing.
In the State of California a spark attester is required by law
(Section 4442 of the California Public Resources Code).
Other states may have similar laws, Federal laws apply on
federal lands, If you equip the muffler with a spark attester,
it must be maintained in effective working order,
Air Coo_ing 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".
