The emission control systems on your Honda engine were
designed, built, and certified to conform with EPA, California
(models certified for sale in California), and Canadian emission
regulations. We recommend the use of Honda Genuine 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.
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.
An Air Index Information 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 to 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
