California, United States and Canada Emis-
sions Control 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 California, new small off-road
engines model year 2006 and later must be de-
signed, built and equipped to meet the State’s strin-
gent anti-smog standards. Elsewhere in the United
States, new non-road, spark-ignition engines certi-
fied for model year 1997 and later must meet simi-
lar standards set forth by the U.S. EPA. B&S must
warrant the emissions control system on your en-
gine for the periods of time listed below, provided
there has been no abuse, neglect or improper
maintenance of your small off-road engine.
Your emissions control system includes parts
such as the carburetor, air cleaner, ignition sys-
tem, 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.

Defects Warranty Coverage
Small off-road engines are warranted relative to
emissions control parts defects for a period of two
years, subject to provisions set forth below. If any
covered part on your engine is defective, the part
will be repaired or replaced by B&S.
Owner’s Warranty Responsibilities
As the small off-road engine owner, you are re-
sponsible for the performance of the required
maintenance listed in your Operating and Mainte-
nance Instructions. B&S recommends that you
retain all your receipts covering maintenance 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
maintenance.
As the small off-road engine owner, you should
however be aware that B&S may deny you war-
ranty 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 war-
ranty 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 a
B&S Service Representative at 1-414-259-5262.
The emissions warranty is a defects warranty.
Defects are judged on normal engine perfor-
mance. The warranty is not related to an in-use
emissions test.

Emissions Control System Warranty Statement
(Owner’s Defect Warranty Rights and Obligations)
The following are specific provisions relative to your
Emissions Control Defects Warranty Coverage. It is
in addition to the B&S engine warranty for non-reg-
ulated engines found in the Operating and Mainte-
nance 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 purchased.
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 sen-
sitive valves and switches
• Connectors and assemblies
2. Length of Coverage
B&S warrants to the initial owner and each sub-
sequent purchaser that the Warranted Parts
shall be free from defects in materials and work-
manship which caused the failure of the War-
ranted 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, includ-
ing diagnostic labor which leads to the deter-
mination 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 Authorized 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. Warranty coverage shall be excluded for
failures of Warranted Parts which are not original
B&S parts or because of abuse, neglect or im-
proper maintenance as set forth in the B&S En-
gine 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
replacement as required maintenance or which
is scheduled only for regular inspection to the
effect of “repair or replace as necessary” shall
be warranted as to defects for the warranty peri-
od. 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 defined in the B&S
Operating and Maintenance Instructions.
6. Consequential Coverage
Coverage hereunder shall extend to the failure
of any engine components caused by the failure
of any Warranted Part still under warranty.
Briggs & Stratton Emissions Control
Defects Warranty Provisions
Engines that are certified to meet the California
Air Resources Board (CARB) Tier 2 Emission
Standards must display information regarding the
Emissions Durability Period and the Air Index.
Briggs & Stratton makes this information available
to the consumer on our emission 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 emission compliant for
125 hours of actual engine running time.
Intermediate:
Engine is certified to be emission compliant for
250 hours of actual engine running time.
Extended:
Engine is certified to be emission 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 En-
gineers) code J1940 (Small Engine Power & Torque Rating
Procedure), and rating performance has been obtained and
corrected in accordance with SAE J1995 (Revision
2002-05). Torque values are derived at 3060 RPM; horse-
power 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-engine variabili-
ty. Given both the wide array of products on which engines
are placed and the variety of environmental issues applica-
ble to operating the equipment, the gas engine will not de-
velop the rated gross power when used in a given piece of
power equipment (actual on-site" or net power). This differ-
ence is due to a variety of factors including, but not limited
to, accessories (air cleaner, exhaust, charging, cooling, car-
buretor, fuel pump, etc.), application limitations, ambient
operating conditions (temperature, humidity, altitude), and
engine-to-engine variability. Due to manufacturing and ca-
pacity limitations, Briggs & Stratton may substitute an engine
of higher rated power for this Series engine.
