The warranty on emissions-related parts is as follows:
• Any warranted part that is not scheduled for
replacement as required maintenance in the owner’s
manual supplied, is warranted for the warranty period
stated above. If any such part fails during the period of
warranty coverage, the part will be repaired or replaced
by B&S at no charge to the owner. Any such part
repaired or replaced under the warranty will be
warranted for the remaining warranty period.
• Any warranted part that is scheduled only for regular
inspection in the owner’s manual supplied, is warranted
for the warranty period stated above. Any such part
repaired or replaced under warranty will be warranted
for the remaining warranty period.
• Any warranted part that is scheduled for replacement as
required maintenance in the owner’s manual supplied, is
warranted for the period of time prior to the first
scheduled replacement point for that part. If the part fails
prior to the first scheduled replacement, the part will be
repaired or replaced by B&S at no charge to the owner.
Any such part repaired or replaced under warranty will
be warranted for the remainder of the period prior to the
first scheduled replacement point for the part.
• Add on or modified parts that are not exempted by the
Air Resources Board may not be used. The use of any
non exempted add on or modified parts by the owner
will be grounds for disallowing a warranty claim. The
manufacturer will not be liable to warrant failures of
warranted parts caused by the use of a non exempted
add on or modified part.
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 On Your Small Off-Road Engine
Emissions Label
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.
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 emissions standards. For Phase 2
certified engines, 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
