3. Consequential Coverage
Coverage shall extend to the failure of any engine components
caused by the failure of any warranted emissions parts.
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.
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 Operator's Manual. The following categories
are used:
Moderate:
Engines at or less than 80 cc displacement are certified to be
emissions compliant for 50 hours of actual engine running time.
Engines greater than 80 cc displacement are certified to be
emissions compliant for 125 hours of actual engine running
time.
Intermediate:
Engines at or less than 80 cc displacement are certified to be
emissions compliant for 125 hours of actual engine running
time. Engines greater than 80 cc displacement are certified to
be emissions compliant for 250 hours of actual engine running
time.
Extended:
Engines at or less than 80 cc displacement are certified to be
emissions compliant for 300 hours of actual engine running
time. Engines greater than 80 cc displacement are 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 at or less than 80 cc displacement:
Category C = 50 hours, Category B = 125 hours, Category A =
300 hours
For engines greater than 80 cc displacement and 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
