Replacement Parts
The emission control systems on your Hondaengine were designed, built, and
certified to conform with EPA and California emission regulations. We recom-
mend 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 repla.cement parts that are not oithe original design and quality may
impair the effec:tiveness 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 lcertify 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 23. 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 unusu-
ally wet or dusty conditions, will require more frequent service.
