Replacement Parts
The emission control systems on your new 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 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 24. Remember that
this schedule is based on the assumption that your mower 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.
