Changing the spark plug will help your engine to start easier
and run better.

porcelain is cracked. Use the recommended
replacement plug. See Specifications.
4. Check electrode gap with wire feeler gauge and reset
spark plug gap to recommended gap if necessary (see
Specifications).
5. Install spark plug and tighten firmly.
Inspect Muffler and Spark Arrester
Inspect the muffler for cracks, corrosion, or other damage.
Remove the spark arrester, if equipped, and inspect for
damage or carbon blockage. If replacement parts are
required, make sure to use only original equipment
replacement parts.
WARNING Exhaust heat/gases could ignite
combustibles, structures or damage fuel
tank causing a fire, resulting in death,
serious injury and/or property damage.
Contact with muffler area could cause burns resulting in
serious injury.
• 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.
• It is a violation of California Public Resource Code, Section
4442, to use or operate the engine on any forest-covered,
brush-covered, or grass-covered land unless the exhaust
system is equipped with a spark arrester, as defined in Section
4442, maintained in effective working order. Other states or
federal jurisdictions may have similar laws.
Contact the original equipment manufacturer, retailer, or dealer
to obtain a spark arrester designed for the exhaust system
installed on this engine.

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 qualified service
dealer clean the cooling system per recommended intervals
(see Maintenance Schedule in beginning of Maintenance
section). Equally important is to keep top of engine free from
debris. See Clean Debris.
Carburetor Adjustment
The carburetor on this engine is low emission. It is equipped
with a non-adjustable idle mixture valve. Top speed has been
set at the factory. If adjustment is required, see an
authorized service dealer.
CAUTION Excessively high operating speeds could
result in minor injury and/or pressure washer damage.
Excessively low speeds impose a heavy load.
• DO NOT tamper with governor spring, links or other parts to
increase engine speed. Pressure washer supplies correct rated
pressure and flow when running at governed speed.
• DO NOT modify pressure washer in any way.
