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

Your Warranty Rights and Obligations
For Briggs & Stratton Engine Models with "F" Trim Designation (Model-Type-

The California Air Resources Board, U.S. EPA, and Briggs & Stratton (B&S) are
pleased to explain the exhaust and evaporative emissions ("emissions") control system
warranty on your 2021-2023 engine. In California, new equipment that use small off-
road engines 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/
equipment 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/equipment at no cost
to you including diagnosis, parts, and labor.
Manufacturer's Warranty Coverage:
The exhaust and evaporative emissions control system on your engine/equipment
is warranted for two years. If any evaporative emission-related part on your engine/
equipment is defective, the part will be repaired or replaced by B&S.
Owner's Warranty Responsibilities:
• As the engine/equipment 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/equipment owner, you should however be aware that B&S may
deny you warranty coverage if your engine/equipment or a part has failed due
to abuse, neglect, or improper maintenance or unapproved modifications.
• You are responsible for presenting your engine/equipment to a B&S
distribution center or service center as soon as the problem exists. The
14
warranty repairs shall be completed in a reasonable amount of time, not
