(Owner's Defect Warranty Rights and Obligations)
California, United States and Canada Emissions Con‐
trol Defects Warranty Statement
The California Air Resources Board (CARB), U.S. EPA and
B&S are pleased to explain the Emissions Control System
Warranty on your small off‐road engine (SORE). In Califor‐
nia, new small off‐road engines model year 2006 and later
must be designed, built and equipped to meet the State's
stringent anti‐smog standards. Elsewhere in the United
States, new non‐road, spark‐ignition engines certified for
model year 1997 and later must meet similar standards set
forth by the U.S. EPA. 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 im‐
proper maintenance of your small off‐road engine.
Your emissions control system includes parts such as the
carburetor, air cleaner, ignition system, fuel line, muffler
and catalytic converter. Also included may be connectors
and other emissions related assemblies.
Where a warrantable condition exists, B&S will repair
your small off‐road engine at no cost to you including
diagnosis, parts and labor.
Briggs & Stratton Emissions Control
Defects Warranty Coverage
Small off‐road engines are warranted relative to emis‐
sions control parts defects for a period of two years, sub‐
ject to provisions set forth below. If any covered part on
your engine is defective, the part will be repaired or re‐
placed by B&S.
Owner's Warranty Responsibilities
As the small off‐road engine owner, you are responsible
for the performance of the required maintenance listed in
your Operating and Maintenance Instructions. B&S rec‐
ommends that you retain all your receipts covering main‐
tenance on your small off‐road engine, but B&S cannot
deny warranty solely for the lack of receipts or for your
failure to ensure the performance of all scheduled main‐
tenance.
As the small off‐road engine owner, you should however
be aware that B&S may deny you warranty coverage if
your small off‐road engine or a part has failed due to
abuse, neglect, improper maintenance or unapproved
modifications.
You are responsible for presenting your small off‐road
engine to an Authorized B&S Service Dealer as soon as
a problem exists. The undisputed warranty repairs should
be completed in a reasonable amount of time, not to ex‐
ceed 30 days.
If you have any questions regarding your warranty rights
and responsibilities, you should contact a B&S Service
Representative at 1‐414‐259‐5262.
The emissions warranty is a defects warranty. Defects
are judged on normal engine performance. The warranty
is not related to an in‐use emissions test.

Briggs & Stratton Emissions Control
Defects Warranty Provisions
The following are specific provisions relative to your Emis‐
sions Control Defects Warranty Coverage. It is in addition
to the B&S engine warranty for non‐regulated engines
found in the Operating and Maintenance Instructions.
1. Warranted 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 engine pur‐
chased.
a. Fuel Metering System
• Cold start enrichment system (soft choke)
• Carburetor and internal parts
• Fuel pump
• 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
B&S warrants to the initial owner and each subsequent
purchaser that the Warranted Parts shall be free from
defects in materials and workmanship which caused
the failure of the Warranted Parts for a period of two
years from the date the engine is delivered to a retail
purchaser.
3. No Charge
Repair or replacement of any Warranted Part will be
performed at no charge to the owner, including diag‐
nostic labor which leads to the determination that a
Warranted Part is defective, if the diagnostic work is
performed at an Authorized B&S Service Dealer. For
emissions warranty service contact your nearest Autho‐
rized B&S Service Dealer as listed in the "Yellow
Pages" under "Engines, Gasoline," "Gasoline Engines,"
"Lawn Mowers," or similar category.
4. Claims and Coverage Exclusions
Warranty claims shall be filed in accordance with the
provisions of the B&S Engine Warranty Policy. Warran‐
ty coverage shall be excluded for failures of Warranted
Parts which are not original B&S parts or because of
abuse, neglect or improper maintenance as set forth in
the B&S Engine Warranty Policy. B&S is not liable to
cover failures of Warranted Parts caused by the use of
add‐on, non‐original, or modified parts.

5. Maintenance

Any Warranted Part which is not scheduled for replace‐
ment as required maintenance or which is scheduled
only for regular inspection to the effect of "repair or re‐
place as necessary" shall be warranted as to defects
for the warranty period. Any Warranted Part which is
scheduled for replacement as required maintenance
shall be warranted as to defects only for the period of
time up to the first scheduled replacement for that part.
Any replacement part that is equivalent in performance
and durability may be used in the performance of any
maintenance or repairs. The owner is responsible for
the performance of all required maintenance, as de‐
fined in the B&S Operating and Maintenance Instruc‐
tions.
6. Consequential Coverage
Coverage hereunder shall extend to the failure of any
engine components caused by the failure of any War‐
ranted Part still under warranty.

Look For Relevant Emissions
Durability Period and
Air Index Information On
Your Engine Emissions Label
Engines that are certified to meet the California Air
Resources Board (CARB) Tier 2 Emissions Standards
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 emission 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.
Certain Briggs & Stratton engines will be certified to meet
the United States Environmental Protection Agency
(USEPA) Phase 2 emission 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 emission 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.

TECHNICAL INFORMATION

Engine Power Rating Information
The gross power rating for individual gas engine models is
labeled in accordance with SAE (Society of Automotive
Engineers) code J1940 (Small Engine Power & Torque
Rating Procedure), and rating performance has been ob‐
tained and corrected in accordance with SAE J1995 (Revi‐
sion 2002‐05). Torque values are derived at 3060 RPM;
horsepower values are derived at 3600 RPM. Actual gross
engine power will be lower and is affected by, among other
things, ambient operating conditions and engine‐to‐en‐
gine variability. Given both the wide array of products on
which engines are placed and the variety of environmental
issues applicable to operating the equipment, the gas en‐
gine will not develop the rated gross power when used in a
given piece of power equipment (actual "on‐site" or net
power). This difference is due to a variety of factors includ‐
ing, but not limited to, accessories (air cleaner, exhaust,
charging, cooling, carburetor, fuel pump, etc.), application
limitations, ambient operating conditions (temperature,
humidity, altitude), and engine‐to‐engine variability. Due to
manufacturing and capacity limitations, Briggs & Stratton
may substitute an engine of higher rated power for this
Series engine.
