3. Consequential Coverage
Coverage shall extend to the failure of any engine components caused by the
failure of any warranted emissions parts.
Look For Relevant Emissions Durability Period and Air Index Information
Engines that are certified to meet the California Air Resources Board (CARB)
small off-road Emissions Standard must display information regarding the
Emissions Durability Period and the Air Index. Briggs & Stratton makes this
information available to the consumer on our emissions labels. The engine
emissions label will indicate certification information.
The Emissions Durability Period describes the number of hours of actual
running time for which the engine is certified to be emissions compliant, assuming
proper maintenance in accordance with the Operating & Maintenance Instructions.
The following categories are used:
Moderate:
Engine is certified to be emissions compliant for 125 hours of actual engine
running time.
Intermediate:
Engine is certified to be emissions compliant for 250 hours of actual engine
running time.

4. Claims and Coverage Exclusions
Warranty claims shall be filed according to the provisions of the B&S engine
warranty policy. Warranty coverage does not apply to failures of emissions parts
that are not original equipment B&S parts or to parts that fail due to abuse,
neglect, or improper maintenance as set forth in the B&S engine warranty policy.
B&S is not liable for warranty coverage of failures of emissions parts caused by
the use of add-on or modified parts.
Extended:
Engine is certified to be emissions compliant for 500 hours of actual engine
running time. For example, a typical walk-behind lawn mower is used 20 to 25
hours per year. Therefore, the Emissions Durability Period of an engine with an
intermediate rating would equate to 10 to 12 years.
Briggs & Stratton engines are certified to meet the United States Environmental
Protection Agency (USEPA) Phase 2 or Phase 3 emissions standards. The
Emissions Compliance Period referred to on the Emissions Compliance label
indicates the number of operating hours for which the engine has been shown to
meet Federal emissions requirements.
For engines less than 225 cc displacement.
Category C = 125 hours, Category B = 250 hours, Category A = 500 hours
For engines of 225 cc or more displacement.
Category C = 250 hours, Category B = 500 hours, Category A = 1000 hours
