Oil
Capacity
Engine without oil filter holds approximately 1-7/8 quarts
(60 ounces; 1.8 liter).
Engine equipped with oil filter holds approximately
2 quarts (64 ounces; 1.9 liters).
Recommendations
S Use a high quality detergent motor oil, such as
Briggs & Stratton 30W, Part Number 100005 (20 oz)
or 100028 (48 oz).
S DO NOT use special additives.
S Choose a viscosity according to the table shown.
Note: Synthetic oil meeting ILSAC GF-2,
API certification mark and API service sym-
bol (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.
* 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.
** SAE 30 oil, if used below 40° F (4° C), will
result in hard starting and possible engine
bore damage due to inadequate
lubrication.

Fuel
Recommendations
S Use clean, fresh, regular unleaded gasoline with a
minimum of 85 octane. Fresh fuel prevents gum from
forming in the fuel system or on essential carburetor
parts. Purchase fuel in quantity that can be used
within 30 days.
S Do not use gasoline which contains Methanol.
S Do not mix oil with gasoline.
S For engine protection use Briggs & Stratton
Gasoline Additive available from your Authorized
Briggs & Stratton Dealer (P/N 5041 or single use
pouch).
S This engine is certified to operate on gasoline.
Exhaust Emission Control System: EM (Engine
Modifications).
Adding Fuel
1. Clean area around fuel cap and remove.
2. Replace cap before starting.
Some fuels, called oxygenated or reformulated
gasoline, are gasoline 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.
CAUTION
Starting engine creates sparking.
Fuel vapors are extremely
flammable and explosive. Fire or
explosion can cause severe
burns or death.
If fuel spills, wait until it evaporates
before starting engine.
DO NOT use pressurized starting
fluids.
WARNING
S Fuel equipment outdoors, away from open
flames, sparks and other ignition sources, such
as appliances with pilot lights.
S Store fuel away from ignition sources.
S Turn engine OFF and let engine
cool at least 2 minutes before
removing fuel cap.
S Fill fuel tank outdoors or in
well-ventilated area.
S DO NOT overfill fuel tank. Fill tank
to approximately 1-1/2 inches below
top of neck to allow for fuel
expansion.
S If fuel spills, wait until it evaporates
before starting engine.
S Keep fuel away from sparks, open
flames, pilot lights, heat and other
ignition sources.

Technical Information
Power Ratings: The power ratings for an individual
engine model are initially developed by starting with
SAE (Society of Automotive Engineers) code J1940
(Small Engine Power & Torque Rating Procedure)
(Revision 2002-05). Given both the wide array of
products on which our engines are placed, and the
variety of environmental issues applicable to operating
the equipment, it may be that the engine you have
purchased will not develop the rated horsepower when
used in a piece of power equipment (actual “on-site”
power). This difference is due to a variety of factors
including, but not limited to, the following: differences in
altitude, temperature, barometric pressure, humidity,
fuel, engine lubrication, maximum governed engine
speed, individual engine to engine variability, design of
the particular piece of power equipment, the manner in
which the engine is operated, engine run-in to reduce
friction and clean out of combustion chambers,
adjustments to the valves and carburetor, and other
factors. The power ratings may also be adjusted based
on comparisons to other similar engines utilized in
similar applications, and will therefore not necessarily
match the values derived using the foregoing codes.
Emission Information
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

Maintenance
Regular maintenance will improve the performance and
extend the life of the engine. See any Authorized Briggs
& Stratton Dealer for service. Use only genuine Briggs
& Stratton parts. Other parts may not perform as
well, may damage the engine, and may result in
injury. In addition, use of other parts may void your
warranty.
Emission Control
Maintenance, replacement or repair of the emission
control devices and systems may be performed by
any nonroad engine repair establishment or
individual. However, to obtain no charge repairs under
the terms and provisions of the Briggs & Stratton
warranty statement, any service or emission control part
repair or replacement must be performed by a factory
authorized dealer. See Emission Warranty section for
details.
Follow the instructions and
schedules indicated below.
Unintentional sparking can result
in fire or electric shock.
Fire or explosion can cause
severe burns or death.
Unintentional start-up can result
in entanglement, traumatic
amputation, or laceration.
Before performing maintenance:

Storage
Engines stored over 30 days need special attention.
1. To prevent gum from forming in fuel system or on
essential carburetor parts:
a) if fuel tank contains oxygenated or
reformulated gasoline (gasoline blended with
an alcohol or an ether), run engine until it
stops from lack of fuel, or
b) if fuel tank contains gasoline, either run engine
until it stops from lack of fuel, or add a gasoline
additive to the gas in the tank. (See parts list.
Single-use pouches of gas additive are
available from your service dealer.) If you use
a gas additive, run the engine for several
minutes to circulate the additive through the
carburetor. Then, engine and fuel can be
stored up to 24 months.
2. While engine is still warm, change oil.
3. Remove spark plug and pour about 1/2 oz. (15ml)
of engine oil into cylinder. Replace spark plug and
crank slowly to distribute oil.
4. Clean engine of surface debris, chaff or grass.
5. Store in a clean, dry area. Do not store in same
area as a stove, furnace, water heater, or other
appliance that uses a pilot light or has a device
that can create a spark.
When Transporting Equipment:
S Transport with fuel tank EMPTY
or with fuel shut-off valve OFF.
When storing gasoline or
equipment with fuel in tank:
S Store away from furnaces,

Warranty Information
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)
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 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 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 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 (check oil level daily or after every
8 hours of operation. Refill when necessary and
change at recommended intervals.) OIL GARD®
may not shut down running engine. Engine
damage may occur if oil level is not properly
maintained. Read Operating & Maintenance
Instructions.
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, re-assembly, or use of a
non-original air cleaner element or cartridge. (At
recommended intervals, clean and re-oil the
Oil-Foam
element or the foam pre-cleaner, and
replace the cartridge.) Read Operating &
Maintenance Instructions.
7. Parts damaged by over-speeding, or overheating
caused by grass, debris, or dirt, which plugs or
clogs the cooling fins, or flywheel area, or damage
caused by operating the engine in a confined area
without sufficient ventilation. (Clean fins on the
cylinder, cylinder head and flywheel at
recommended intervals.) Read Operating &
Maintenance Instructions.
8. Engine or equipment parts broken by excessive
vibration caused by a loose engine mounting,
loose cutter blades, unbalanced blades or loose or
unbalanced impellers, improper attachment of
equipment to engine crankshaft, over-speeding or
other abuse in operation.
9. A bent or broken crankshaft, caused by striking a
solid object with the cutter blade of a rotary lawn
mower, or excessive v-belt tightness.
10. Routine tune-up or adjustment of the engine.
11. Engine or engine component failure, i.e.,
combustion chamber, valves, valve seats, valve
guides, or burned starter motor windings, caused
by the use of alternate fuels such as, liquified
petroleum, natural gas, altered gasolines, etc.
Warranty is available only through service dealers
which have been authorized by Briggs & Stratton
Corporation. your nearest Authorized Service
Dealer is listed in the “Yellow Pages™” of your
telephone directory under “Engines, Gasoline” or
“Gasoline Engines,” “Lawn Mowers,” or similar
category.
ABOUT YOUR ENGINE WARRANTY
(Cette page ne s'applique que pour le Canada et les EtatsĆUnis)
Déclaration de garantie du système de contrôle des émissions de Briggs & Stratton Corporation (B&S), du California Air Resources Board
(CARB) et de la United States Environmental Protection Agency (U.S. EPA) (Droits et obligations du propriétaire au titre de la garantie contre tout défaut)
Déclaration de garantie pour les défauts de contrôle d'émissions pour la Californie, les ÉtatsĆUnis et le Canada.
Le California Air Resources Board (CARB), U.S. EPA et B&S ont le plaisir de vous expliquer la garantie
du système de contrôle des émissions pour votre petit moteur tout terrain. En Californie, les petits
moteurs tout terrain à partir de l'année 2006 doivent être conçus, fabriqués et équipés pour répondre
aux normes sévères antibrouillard de l'état. Ailleurs aux ÉtatsĆUnis, les nouveaux moteurs tout terrain
à allumage commandé par bougie depuis l'année 1997 doivent répondre à des normes semblables
édictées par la U.S. EPA. B&S doit garantir le système de contrôle des émissions de votre moteur
pendant les durées indiquées ciĆaprès, en supposant que le petit moteur tout terrain ne soit pas mal
utilisé, négligé ou que son entretien ne soit pas défectueux.
Le système de contrôle des émissions comprend des pièces comme le carburateur, le filtre à air, le
système d'allumage, la Durit de carburant, le silencieux et le convertisseur catalytique. Des
connecteurs et d'autres assemblages impliqués dans les émissions peuvent aussi en faire partie.
Si la condition de garantie est remplie, Briggs & Stratton réparera gratuitement votre moteur y compris
le diagnostic, les pièces et la mainĆd'Ĺuvre.
Couverture de la garantie de défectuosité du contrôle des émissions de Briggs & Stratton
Les petits moteurs tout terrain sont garantis en ce qui concerne les défauts des pièces du contrôle

En tant que propriétaire d'un petit moteur non routier, vous êtes responsable de l'entretien nécessaire
indiqué dans les instructions de fonctionnement et d'entretien. Briggs & Stratton recommande de
conserver toutes les factures de maintenance de votre moteur, mais Briggs & Stratton ne peut renier la
garantie uniquement à cause de l'absence de factures.
En tant que propriétaire d'un moteur non routier, vous devez néanmoins savoir que Briggs & Stratton
peut refuser d'appliquer la garantie si la défectuosité de votre moteur ou d'une partie de ce moteur est
due à un abus, une négligence, un entretien non correct ou des modifications non approuvées.

ce », « tondeuses à gazon » ou autre catégorie semblable.
4. Réclamations et exclusions de garantie
Les réclamations sous garantie seront présentées selon les dispositions de la police de garantie
des moteurs de Briggs & Stratton. La garantie ne couvre pas les pièces qui ne sont pas des pièces
Briggs & Stratton d'origine ou qui ont fait l'objet d'abus, de négligence ou d'un mauvais entretien
ainsi qu'indiqué dans la police de garantie des moteurs de Briggs & Stratton. Briggs & Stratton
n'est pas responsable des défaillances dues à l'utilisation de pièces rajoutées, non d'origine ou
modifiées.
5. Entretien
Toute pièce garantie qui ne doit pas être remplacée au titre de l'entretien ou qui est sujette à une
inspection régulière avec la mention « réparer ou remplacer si besoin est » est garantie contre tout
défaut pendant la période de garantie. Toute pièce dont le remplacement est prévu au titre de l'enĆ
tretien n'est garantie contre tout défaut que pendant sa période normale d'utilisation. Les opéraĆ
tions de maintenance et de réparation doivent utiliser des pièces équivalentes sur le plan des perĆ
formances et de la longévité. Le propriétaire est responsable de l'entretien défini dans les instrucĆ
tions de fonctionnement et d'entretien de Briggs & Stratton.
6. Couverture des conséquences
La présente couverture s'étend à la défaillance de tout composant du moteur due à la défaillance
d'une pièce encore sous garantie.
Consultez les informations sur la période de durabilité d'émission et l'INDICE d'air sur l'étiquette d'émission de votre moteur
Les moteurs qui sont certifiés conformes aux normes standards d'émission du California Air Resources Board (CARB) Tier 2, doivent afficher l'information concernant la période de durabilité du système
d'émission et l'INDICE d'air. Cette information est indiquée sur les étiquettes apposées sur les moteurs par Briggs & Stratton. L'étiquette du moteur indiquera les renseignements concernant la certification.
La période de durabilité d'émission indique le nombre d'heures d'utilisation normale pour lequel le moteur est certifié conforme aux normes d'émission sous réserve d'un entretien approprié tel qu'indiqué dans
le manuel d'opération et d'entretien. Les catégories suivantes sont utilisées :
Modéré le moteur est certifié conforme pour 125 heures d'utilisation normale.
Intermédiaire le moteur est certifié conforme pour 250 heures d'utilisation normale.
Prolongé le moteur est certifié conforme pour 500 heures d'utilisation normale.
Par exemple, une tondeuse de modèle standard est utilisée environ 20 à 25 heures par année. Par conséquent, la période de durabilité d'émission d'un moteur dans la catégorie intermédiaire pour ce type de
tondeuse équivaut à 10 à 12 ans.
L'indice d'air est un nombre qui décrit le niveau relatif d'émission pour une catégorie spécifique de moteur. Plus l'indice d'air est bas, plus le moteur est écologique. Cette information est indiquée sous une
forme graphique sur l'étiquette d'émission.
À compter du 1
er
juillet 2000, surveillez la période de conformité d'émission sur les étiquettes
Après le 1
er
juillet 2000, certains moteurs B&S seront certifiés conformes aux normes environnementales d'émission standard du United States Environmental Protection Agency (US EPA) Phase 2. Pour les
moteurs certifiés pour la Phase 2, la période de conformité d'émission mentionnée sur les étiquettes indique le nombre d'heures d'utilisation pour lequel le moteur rencontre les normes fédérales. Pour les
moteurs de force moindre que 225 cc, la catégorie C = 125 heures, B = 250 heures et A = 500 heures. Pour les moteurs de 225 cc et plus, la catégorie C = 250 heures, B = 500 heures et A = 1000 heures.
Le remplacement du moteur portant le modèle de série 400000 est 656 cc. Le remplacement du moteur portant le modèle de série 440000 est 725 cc.
