ADDITIONAL INFORMATION
When. the carburetor has been modified for high altitude operation, the air-fuel
mixture will be too lean for low altitude use. Operation at altitudes below 1,500
meters (5,000 feet) with a modified carburetor may cause the engine to overheat
and result in serious engine damage. For use at low altitudes, have an authorized
servicing dealer return the carburetor to original factory specifications.
SPARK ARRESTER SERVICE (OPTIONAL EQUIPMENT) Your lawn mower 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. An optional USDA approved spark arrester is available from an
authorized Honda servicing dealer.
The spark arrester must be serviced every 100 hours to keep it functioning as
designed.
If the engine has been running, the muffler will be hot enough to burn you. Allow
the muffler to cool before proceeding.
