Replacement Parts
The emissions control systems on your new Honda engine were designed,
built, and certified to conform with EPA, California and Canadian emissions
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 emissions
control system.
A manufacturer of an aftermarket part assumes the responsibility that the part
will not adversely affect emissions 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 emissions regulations.
Maintenance
Follow the MAINTENANCE SCHEDULE on page 34. Remember 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.
