each year, whichever comes first. This will help your engine
to start easier and run better.
1. Clean area around spark plug.
2. Remove and inspect spark plug.
3. Check electrode gap with wire feeler gauge and reset
spark plug gap to recommended gap if necessary (see
Specifications).

porcelain is cracked. Use the recommended
replacement spark plug. See Specifications.

Clean 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 Briggs & Stratton
authorized dealer clean the cooling system (F) per
recommended intervals (see Maintenance Schedule in the
Maintenance section). Equally important is to keep top of
engine free from debris. Also see Cleaning.
Check Valve Clearance
Regular valve clearance check and adjustment will improve
performance and extend engine life. This procedure cannot
be done without partial engine disassembly and the use of
special tools. For this reason we recommend that you have
an authorized dealer check and adjust valve clearance at
250 hours or as recommended (see Maintenance Schedule in
the Maintenance section).
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 Briggs & Stratton Authorized
Dealer.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
Contact with muffler area can result in serious
burns.
Exhaust heat/gases can ignite combustibles,
structures or damage fuel tank causing a fire.
• DO NOT touch hot parts and AVOID hot exhaust gases.
• Allow equipment to cool before touching.
• Keep at least 5 feet (1.5 m) of 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.
