GENERAL INFORMATION
In the state of California, OHV Models 210000, 280000 and
310000 engines are certified by the California Air Resources
Board to meet emissions standards for 250 hours. Such
certification does not grant the purchaser, owner or operator of
this engine any additional warranties with respect to the
performance or operational life of this engine. This engine is
warranted solely according to the product and emissions
warranties stated elsewhere in this manual.
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
obtained and corrected in accordance with SAE J1995
(Revision 2002-05). Actual gross engine power will be lower
and is affected by, among other things, ambient operating
conditions and engine-to-engine 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 engine will not develop the rated gross
power when used in a given piece of power equipment
(actual on-site" or net horsepower). This difference is due to
a variety of factors including, but not limited to, accessories
(air cleaner, exhaust, charging, cooling, carburetor, fuel
pump, etc.), application limitations, ambient operating
conditions (temperature, humidity, altitude), and engine-toengine variability. Due to manufacturing and capacity
limitations, Briggs & Stratton may substitute an engine of
higher rated power for this Series engine.

WARNING
Starting engine creates sparking.
Sparking can ignite nearby flammable
gases.
Explosion and fire could result.
• If there is natural or LP gas leakage in area, do not
start engine.
• Do not use pressurized starting fluids because
vapors are flammable.
GB
WARNING
Fuel and its vapors are extremely
flammable and explosive.
Fire or explosion can cause severe
burns or death.
WHEN FUELING
• Turn engine OFF and let engine cool at least 2
minutes before removing cap or re-fueling engine.
• Fill fuel tank outdoors or in well-ventilated area.
• On GASOLINE operated engines, do not overfill
fuel tank. Fill tank to approximately 1-1/2 inch below
lowest portion of fill opening to allow for fuel
expansion.
• Keep gasoline away from sparks, open flames, pilot
lights, heat, and other ignition sources.
• Check fuel lines, tank, cap, and fittings frequently
for cracks or leaks. Replace if necessary.
WHEN STARTING ENGINE
• Make sure spark plug, muffler, fuel cap and air
cleaner are in place, and firmly secured by

Choose the SAE viscosity grade of oil from this chart that
matches the starting temperature anticipated before the next
oil change.
* Air cooled engines run hotter than automotive engines.
The use of non-synthetic multi-viscosity oils (5W-30,
10W-30, etc.) in temperatures above 40° F (4° C) will
result in higher than normal oil consumption. When using
a multi-viscosity oil, check oil level more frequently.
** Use of SAE 30 oil below 40° F (4° C) will result in hard
starting and possible engine damage due to inadequate lubrication.
Note:
Synthetic oil meeting ILSAC GF-2, API
certification mark and API service symbol (shown
at left) with SJ/CF ENERGY CONSERVING" or
higher, is an acceptable oil at all temperatures.
Use of synthetic oil does not alter required oil
change intervals.

FUEL RECOMMENDATIONS
Gasoline Powered Engines
Use clean, fresh, lead-free, regular gasoline with a minimum of
85 octane. Leaded gasoline may be used if it is commercially
available and if unleaded is unavailable. Purchase fuel in
quantity that can be used within 30 days. See Storage
instructions.
In U.S.A. leaded gasoline may not be used. Some fuels, called
oxygenated or reformulated gasolines, are gasolines blended
with alcohols or ethers. Excessive amounts of these blends
can damage the fuel system or cause performance problems.
If any undesirable operating symptoms occur, use gasoline
with a lower percentage of alcohol or ether.
This engine is certified to operate on gasoline. Exhaust
Emission Control System: EM (Engine Modifications).
Do not use gasoline which contains Methanol. Do not mix oil
with gasoline.
For engine protection, we recommend using Briggs & Stratton
Fuel Stabilizer available from an Authorized Briggs & Stratton
Service Dealer.

Briggs & Stratton Corporation (B&S),
the California Air Resources Board (CARB)
and the United States
Environmental Protection Agency (U.S. EPA)
Emissions Control System Warranty Statement
(Owner’s Defect Warranty Rights and Obligations)
California, United States and Canada Emissions 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 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 improper
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
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 responsible for the performance of the required
maintenance listed in your Operating and Maintenance 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 your 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 offroad 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 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 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
Emissions 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 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)

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 diagnostic 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 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 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
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 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 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.

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 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.

ABOUT YOUR ENGINE WARRANTY
Briggs & Stratton welcomes warranty repair and apologizes to
you for being inconvenienced. Any Authorized Service Dealer
may perform warranty repairs. Most warranty repairs are handled routinely, but sometimes requests for warranty service
may not be appropriate. For example, warranty would not apply
if engine damage occurred because of misuse, lack of routine
maintenance, shipping, handling, warehousing or improper
installation. Similarly, warranty is void if the serial number of the
engine has been removed or the engine has been altered or
modified.
If a customer differs with the decision of the Service Dealer, an
investigation will be made to determine whether the warranty
applies. Ask the Service Dealer to submit all supporting facts to
his Distributor or the Factory for review. If the Distributor or the
Factory decides that the claim is justified, the customer will be
fully reimbursed for those items that are defective. To avoid misunderstanding which might occur between the customer and
the Dealer, listed below are some of the causes of engine failure
that the warranty does not cover.
Normal wear:
Engines, like all mechanical devices, need periodic parts service
and replacement to perform well. Warranty will not cover repair
when normal use has exhausted the life of a part or an engine.
Improper maintenance:
The life of an engine depends upon the conditions under which it
operates, and the care it receives. Some applications, such as
tillers, pumps and rotary mowers, are very often used in dusty or
dirty conditions, which can cause what appears to be premature
wear. Such wear, when caused by dirt, dust, spark plug cleaning
grit, or other abrasive material that has entered the engine because of improper maintenance, is not covered by warranty.
This warranty covers engine related defective material and/
or workmanship only, and not replacement or refund of the
equipment to which the engine may be mounted. Nor does
the warranty extend to repairs required because of:
1. PROBLEMS CAUSED BY PARTS THAT ARE NOT
ORIGINAL BRIGGS & STRATTON PARTS.
2. Equipment controls or installations that prevent starting,
cause unsatisfactory engine performance, or shorten engine life. (Contact equipment manufacturer.)
3. Leaking carburetors, clogged fuel pipes, sticking valves,
or other damage, caused by using contaminated or stale
fuel. (Use clean, fresh, lead-free gasoline and Briggs &
Stratton Fuel Stabilizer, Part No. 5041.)
4. Parts which are scored or broken because an engine was
operated with insufficient or contaminated lubricating oil,
or an incorrect grade of lubricating oil. OIL GARD may not
shut down running engine. Engine damage may occur if
oil level is not properly maintained.
5. Repair or adjustment of associated parts or assemblies
such as clutches, transmissions, remote controls, etc.,
which are not manufactured by Briggs & Stratton.
6. Damage or wear to parts caused by dirt, which entered
the engine because of improper air cleaner maintenance,
