Inspect Muffler and Spark Arrester
The engine exhaust muffler has a spark arrester
screen. Inspect the muffler for cracks, corrosion,
or other damage. Inspect spark arrester screen for
damage or carbon blockage. Clean if carbon blockage
is found or replace if damaged. 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 or serious injury.
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 ft. (1.5 m) of clearance on all sides of

order. Other states or federal jurisdictions may have
similar laws.

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 (D) per recommended intervals (see
Maintenance Schedule in the Maintenance section).
Equally important is to keep top of engine free from
debris. Also see Cleaning.

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 a Briggs & Stratton authorized dealer.
CAUTION Excessively high operating speeds
could result in minor injury.
Excessively low operating speeds impose a heavy
load.
• DO NOT tamper with governor spring, links or other parts
to increase engine speed. Generator supplies correct
rated frequency and voltage when running at governed
speed.
• DO NOT modify generator in any way.
