MAINTENANCE & ADJUSTMENTS
Tampering and Altering Tampering with or altering the emission control system may increase emissions
beyond the legal limit. Among those acts that constitute tampering are:
l
Removal or alteration of any part of the intake, fuel, or exhaust systems.
l
Altering or defeating the governor linkage or speed-adjusting mechanism to
cause the engine to operate outside its design parameters.
Problems that may Affect Emissions If you are aware of any of the following symptoms, have your engine inspected
and repaired by your servicing dealer.
l
Hard starting or stalling after starting.
l
Rough idle.
l
Misfiring or backfiring under load.
l
Afterburning (backfiring).
l
Black exhaust smoke or high fuel consumption.
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 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 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.
Maintenance Follow the maintenance schedule on the following 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.
