TECHNICAL INFORMATION
Problems That May Affect Emissions
If you are aware of any of the following symptoms, have your engine
inspected and repai
red by your authorized Honda servicing dealer.
• Hard starting or stalling after starting
• Rough idle
• Misfiring or backfiring under load
• Afterburning (backfiring)
• Black exhaust smoke or high fuel consumption
Replacement Parts
The emission control systems on your new Honda engine were
designed, built, and cert
ified to conform with EPA and California
emission regulations. We recommend the use of Honda Genuine 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 par
t will n
ot adver
sely 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 45. 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 dusty conditions, will require more frequent
service.
