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 feet (1.5 m) of clearance on all sides of
generator including overhead.

to obtain a spark arrester designed for the exhaust system
installed on this engine.

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.
