Replacement Parts
The emission control systems on your new Honda engine were designed,
built, and certified to conform with EPA and California emission regulations.
We recommend the use genuine Honda parts whenever you have mainte-
nance 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 afailure of the engine
to comply with emission regulations.
Maintenance
Follow the Maintenance Schedule on page 26. 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.
