Emission Control System Information
Emission Control System Warranty
Your new Honda complies with both the U.S. EPA and State of California
emission regulations. American Honda provides the same emission
warranty coverage for Honda Power Equipment engines sold in all 50
states. In all areas of the United States, your Honda Power Equipment
engine is designed, built, and equipped to meet the U.S. EPA and California
Air Resources Board emission standard for spark ignited engines.
Warranty Coverage
Honda Power Equipment engines certified to CARB and EPA regulations
are covered by this warranty to be free from defects in materials and
workmanship that may keep it from meeting the applicable EPA and
CARB emissions requirements for a minimum of 2 years or the length of
the Honda Power Equipment Distributor's Limited Warranty, whichever is
longer, from the original date of delivery to the retail purchaser. This
warranty is transferable to each subsequent purchaser for the duration of
the warranty period. Warranty repairs will be made without charge for
diagnosis, parts, and labor. Information about how to make a warranty
claim, as well as a description of how a claim can be made and/or how
service can be provided, can be obtained by contacting an authorized
Honda Power Equipment dealer or by contacting American Honda at the
following:
Email: powerequipmentemissions@ahm.honda.com
Telephone: (888) 888-3139
The covered components include all components whose failure would
increase an engine's emissions of any regulated pollutant or evaporative
emissions. A list of specific components can be found in the separately
included emissions warranty statement.
Specific warranty terms, coverage, limitations and manner of seeking
warranty service are also set forth in the separately included emissions
warranty statement. In addition, the emissions warranty statement can
also be found on the Honda Power equipment website or at the
following link:

Source of Emissions
The combustion process produces carbon monoxide, oxides of nitrogen,
and hydrocarbons. Control of hydrocarbons and oxides of nitrogen are
very important because, under certain conditions, they react to form
photochemical smog when subjected to sunlight. Carbon monoxide
does not react in the same way, but it is toxic.
Honda utilizes appropriate air/fuel ratios and other emissions control
systems to reduce the emissions of carbon monoxide, oxides of nitrogen,
and hydrocarbons.
Additionally, Honda fuel systems utilize components and control
technologies to reduce evaporative emissions.
The U.S. and California Clean Air Acts, and Canadian Environmental
Protection Act
U.S. EPA, California, and regulations require all manufacturers to furnish
written instructions describing the operation and maintenance of
emission control systems.
The following instructions and procedures must be followed in order to
keep the emissions from your Honda engine within the emission
standards.
Tampering and Altering
Tampering is a violation of federal and California law.
Tampering with or altering the emission control system may increase
emissions beyond the legal limit. Among those acts that constitute
tampering are:
• Removal or alteration of any part of the intake, fuel, or exhaust
systems.
• 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.
• 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 emissions control systems on your new Honda engine were
designed, built, and certified to conform with U.S. EPA, California, and
emissions 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. Honda
cannot deny coverage under the emission warranty solely for the use of
non-Honda replacement parts or service performed at a location other
than an authorized Honda dealership; you may use comparable EPA
certified parts, and have service performed at non-Honda locations.
However, the use of replacement parts that are not of the original design
and quality may impair the effectiveness of your emissions control
system.
A manufacturer of an aftermarket part assumes the responsibility that
the part will not adversely affect emissions 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 emissions regulations.
Maintenance
As the power equipment engine owner, you are responsible for
completing all required maintenance listed in your owner's manual.
Honda recommends that you retain all receipts covering maintenance on
your power equipment engine, but Honda cannot deny warranty
coverage solely for the lack of receipts or for your failure to ensure that all
scheduled maintenance has been completed.
Follow the MAINTENANCE SCHEDULE on page 7.
Remember that this schedule is based on the assumption that your
engine will be used for its designed purpose. Sustained high-load or
high-temperature operation, or use in dusty conditions, will require more
frequent service.

Air Index

An Air Index Information hang tag/label is applied to engines certified to
an emission durability time period in accordance with the requirements
of the California Air Resources Board.
The bar graph is intended to provide you, our customer, the ability to
compare the emissions performance of available engines. The lower the
Air Index, the less pollution.
The durability description is intended to provide you with information
relating to the engine's emission durability period.
The descriptive term indicates the useful life period for the engine's
emission control system. See your Emission Control System Warranty for
additional information.
Descriptive Term Applicable to Emissions Durability Period
Moderate 50 hours (0–80 cc, inclusive)
125 hours (greater than 80 cc)
Intermediate 125 hours (0–80 cc, inclusive)
250 hours (greater than 80 cc)
Extended 300 hours (0–80 cc, inclusive)
500 hours (greater than 80 cc)
1,000 hours (225 cc and greater)
The Air Index Information hang tag/label must remain on the engine
until it is sold. Remove the hang tag before operating the engine.
