Replacement Parts
The emission control systems on your Honda engine were
designed, built, and certified to conform with EPA, California and
Canadian emission regulations. We recommend the use of
genuine Honda parts whenever you have maintenance done.
These original-design replacement parts are manufactured to the
same standards as the original parts, so you can be confident of
their performance. The use of replacement parts that are not of the
original design and quality may impair the effectiveness of your
emission control system.
A manufacturer of an aftermarket part assumes the responsibility
that the part will not adversely affect emission performance. The
manufacturer or rebuilder of the part must certify that use of the
part will not result in a failure of the engine to comply with
emission regulations.
Maintenance
Follow the maintenance schedule on page . Remember that this
schedule is based on the assumption that your machine will be
used for its designed purpose. Sustained high-load or high-
temperature operation, or use in unusually wet or dusty conditions,
will require more frequent service.
Air Index
An Air Index Information hang tag/label is applied to engines
certified to an emission durability time period in accordance with
the requirements of the California Air Resources Board.
The bar graph is intended to provide you, our customer, the ability
to compare the emissions performance of available engines. The
lower the Air Index, the less pollution.
The durability description is intended to provide you with
information relating the engine's emission durability period. The
descriptive term indicates the useful life period for the engine's
emission control system. See your Emission Control System
Warranty for additional information.
