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

Briggs & Stratton Emissions Warranty
California, U.S. EPA, and Briggs & Stratton, LLC Emissions Control
Warranty - Your Warranty Rights and Obligations
For Briggs & Stratton Engine Models with "B" or "G" Trim Designation
(Model-Type-Trim Representation xxxxxx xxxx Bx or xxxxxx xxxx Gx)
The California Air Resources Board, U.S. EPA, and Briggs & Stratton (B&S) are
pleased to explain the exhaust emissions ("emissions") control system warranty
on your 2021-2023 engine. In California, new small off-road engines and large
spark ignited engines less than or equal to 1.0 liter must be designed, built, and
equipped to meet the State's stringent anti-smog standards. B&S must warrant
the emissions control system on your engine for the periods of time listed below
provided there has been no abuse, neglect or improper maintenance of your small
off-road engine or equipment leading to the failure of the emissions control system.
Your emissions control system may include parts such as the carburetor or fuel-
injection system, the ignition system, catalytic converter, fuel tanks, fuel lines (for
liquid fuel and fuel vapors), fuel caps, valves, canisters, filters, clamps and other
associated components. Also included may be hoses, belts, connectors, and
other emission-related assemblies.
Where a warrantable condition exists, B&S will repair your engine at no cost to you
including diagnosis, parts, and labor.
Manufacturer's Warranty Coverage:
The exhaust emissions control system on your engine is warranted for two years.
If any emissions-related part on your engine is defective, the part will be repaired
or replaced by B&S.
Owner's Warranty Responsibilities:
• As the engine owner, you are responsible for the performance of the required
maintenance listed in your owner's manual. B&S recommends that you
retain all receipts covering maintenance on your engine, but B&S cannot deny
warranty coverage solely for the lack of receipts or for your failure to ensure the
performance of all scheduled maintenance.
• As the engine owner, you should however be aware that B&S may deny you
warranty coverage if your engine or a part has failed due to abuse, neglect, or
improper maintenance or unapproved modifications.
• You are responsible for presenting your engine to a B&S distribution center
or service center as soon as the problem exists. The warranty repairs shall
be completed in a reasonable amount of time, not to exceed 30 days. If you
have a question regarding your warranty rights and responsibilities, you should
contact B&S at 1-800-444-7774 (in USA) or BRIGGSandSTRATTON.COM.
Briggs & Stratton Emissions Control Warranty
Provisions
The following are specific provisions relative to your Emissions Control Warranty
Coverage. It is in addition to the B&S engine warranty for non-regulated engines
found in the Operator's Manual.
1. Warranted Emissions Parts
Coverage under this warranty extends only to the parts listed below (the
emissions control systems parts) to the extent these parts were present on the
B&S engine.
a. Fuel Metering System
• Cold start enrichment system (soft choke)
• Carburetor or fuel injection system
• Oxygen sensor
• Electronic control unit
• Fuel pump module
b. Air Induction System

e. Miscellaneous Items Used in Above Systems
• Vacuum, temperature, position, time sensitive valves and switches
• Connectors and assemblies
• Electronic controls
2. 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.
2. Consequential Coverage
Coverage shall extend to the failure of any engine components caused by the
failure of any warranted emissions parts.
2. 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.
