Length of Coverage
Coverage is for a period of two years from the date of delivery to an ultimate
purchaser, or for the time period listed in the respective engine or product
warranty statement, whichever is greater. B&S warrants to the original purchaser
and each subsequent purchaser that the engine is designed, built, and equipped
so as to conform with all applicable regulations adopted by the Air Resources
Board; that it is free from defects in material and workmanship that could cause
the failure of a warranted part; and that it is identical in all material respects to the
engine described in the manufacturer’s application for certification. The warranty
period begins on the date the engine or equipment is delivered to an ultimate
purchaser.
The warranty on emissions-related parts is as follows:
• Any warranted part that is not scheduled for replacement as required
maintenance in the Operator’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
Operator’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 Operators’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 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
