Inspect Muffler and Spark Arrester
The engine exhaust muffler has a spark arrester screen.
Inspect the muffler for cracks, corrosion, or other damage.
Remove the spark arrester and inspect for damage or carbon
blockage. If replacement parts are required, make sure to
use only original equipment replacement parts.
_i, WARNING

combustibles,
structures or damage
fuel tank causing a fire.
• DO NOTtouch hot parts and AVOID hot exhaust gases.
• Allow equipment to cool before touching.
• Keepat least 5 feet (152 cm) of clearanceon all sides of
generator 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

Clean CoolingSystem
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 service
dealer clean the cooling system per recommended intervals
(see MaintenanceSchedule in the Maintenance section).
Equally important is to keep top of engine free from debris.
Also see Cleaning.
CheckValve 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 Service Dealercheck and adjust valve
clearance at recommended intervals (see Maintenance
Schedule in the Maintenance section).
CarburetorAdjustment
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.
_i, CAUTION
Excessively high operating speeds increase
risk of injury and damage to generator.
Excessively low speeds impose a heavy load.

correct rated frequency and voltage when running at governed
speed.
• DO NOTmodify generator in any way.
