California, U.S. EPA, and Briggs & Stratton Corporation Emissions Control Warranty Statement
Your Warranty Rights And Obligations
For Briggs & Stratton Engine Models with “F” Trim Designation
(Model-Type-Trim Representation xxxxxx xxxx Fx)
The California Air Resources Board, U.S. EPA, and Briggs & Stratton (B&S) are pleased
to explain the emissions control system warranty on your 2016-2018 engine/equipment. In
California, new small o-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/equipment for
the periods of time listed below provided there has been no abuse, neglect, or improper
maintenance of your engine/equipment.
Your exhaust emissions control system may include parts such as the carburetor or fuel
injection system, ignition system, and catalytic converter. Also included may be hoses,
belts, connectors, sensors, and other emissions-related assemblies. Your evaporative
emission control system may include parts such as: carburetors, fuel tanks, fuel lines, fuel
caps, valves, canisters, lters, vapor hoses, clamps, connectors, and other associated
components.
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:
Small o-road engines and large spark ignited engines less than or equal to 1.0 liter, and any related
emissions components of the equipment, are warranted for two years, or for the time period listed in
the respective engine or product warranty statement, whichever is greater. If any emissions-related
part on your B&S 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 Operator’s Manual. B&S recommends that you retain all receipts
covering maintenance on your engine/equipment, but B&S cannot deny warranty solely for the lack
of receipts or 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, improper
maintenance, or unapproved modications.
• You are responsible for presenting your engine/equipment to a B&S distribution center, servicing
dealer, or other equivalent entity, as applicable, as soon as a problem exists. The warranty repairs
should be completed in a reasonable amount of time, not to exceed 30 days. If you have any
questions 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 specic 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 and/or B&S
supplied fuel system.
a. Fuel Metering System
• Cold start enrichment system (soft choke)
• Carburetor or fuel injection system
• Oxygen sensor
• Electronic control unit
• Fuel pump module
• Fuel line, fuel line fittings, clamps
• Fuel tank, cap and tether
• Carbon canister
b. Air Induction System
• Air cleaner
• Intake manifold
• Purge and vent line
c. Ignition System
• Spark plug(s)
• Magneto ignition system
d. Catalyst System
• Catalytic converter
• Exhaust manifold
• Air injection system or pulse valve
e. Miscellaneous Items Used in Above Systems
• Vacuum, temperature, position, time sensitive valves and switches
• Connectors and assemblies
2. Length of Coverage
Coverage is for a period of two years from the date of original purchase, 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 is originally purchased.
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 Operator’s
Manual supplied, is warranted for the period of time prior to the rst scheduled replacement point
for that part. If the part fails prior to the rst 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 rst scheduled replacement point for the
part.
• Add-on or modied parts that are not exempted by the Air Resources Board may not be used. The
use of any non-exempted add-on or modied 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 modied 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 O-Road Engine Emissions Label
Engines that are certied to meet the California Air Resources Board (CARB) small o-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 certication information.
The Emissions Durability Period describes the number of hours of actual running time for which the
engine is certied 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 certied to be emissions compliant for 50 hours of
actual engine running time. Engines greater than 80 cc displacement are certied to be emissions
compliant for 125 hours of actual engine running time.
Intermediate:
Engines at or less than 80 cc displacement are certied to be emissions compliant for 125 hours of
actual engine running time. Engines greater than 80 cc displacement are certied to be emissions
compliant for 250 hours of actual engine running time.
Extended:
Engines at or less than 80 cc displacement are certied to be emissions compliant for 300 hours of
actual engine running time. Engines greater than 80 cc displacement are certied 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 certied 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
