The Power That Works For You)

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 regard-

ing 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.

The Air Index is a calculated number describing the relative level of emissions for a specific engine family. The lower the Air Index,

the cleaner the engine. This information is displayed in graphical form on the emissions label.

After July 1, 2000, Look For Emissions Compliance Period On

Engine Emissions Compliance Label

After July 1, 2000 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, B = 250 hours and A = 500 hours. For engines of 225 cc or more, Category

C = 250 hours, B = 500 hours and A = 1000 hours.

The displacement of model series 110000 engine is 167 cc, and model series 120000 engine is 190 cc.

SAFETY

Gasoline and its vapors are extremely

flammable and explosive.

Fire or explosion can cause severe burns

or death.

WARNING

WHEN ADDING FUEL

• Turn engine OFF and let engine cool at least 2

minutes before removing gas cap.

• Fill fuel tank outdoors or in well-ventilated area.

• Do not overfill fuel tank. Fill tank to approximately

1-1/2 inches below top of neck 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.

• Do not crank engine with spark plug removed.

• If fuel spills, wait until it evaporates before starting

engine.

area and cylinder area.

• Install and maintain in working order a spark

arrester before using equipment on forest-covered,

grass-covered, brush-covered unimproved land.

The state of California requires this (Section 4442

of the California Public Resources Code). Other

states may have similar laws. Federal laws apply

on federal land.

WARNING

Unintentional sparking can result in fire or

electric shock.

Unintentional start-up can result in en-

tanglement, traumatic amputation, or

laceration.

BEFORE PERFORMING ADJUSTMENTS OR

REPAIRS

• Disconnect spark plug wire and keep it away from

spark plug.

• Disconnect battery at negative terminal (only

engines with electric start).

WHEN TESTING FOR SPARK

• Use approved spark plug tester.

ENGINE INFORMATION

TECHNICAL INFORMATION

POWER RATINGS: The power ratings for an individual engine

model are initially developed by starting with SAE (Society of Auto-

motive 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 en-

vironmental 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, tempera-

ture, barometric pressure, humidity, fuel, engine lubrication, maxi-

mum governed engine speed, individual engine to engine variabil-

ity, 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.

MAINTENANCE

ENGINE AND ENGINE PARTS

We recommend that you see an authorized Briggs & Stratton Service Dealer for all maintenance and service of the engine

and engine parts. Use only genuine Briggs & Stratton parts.

WARNING

If you perform any maintenance on the engine, first disconnect the spark plug wire

from the spark plug, and disconnect the battery at the negative terminal (electric

starter engines only) to prevent unintentional sparking. Unintentional sparking can

result in fire or electric shock. Unintentional start-up can result in entanglement,

traumatic amputation or laceration. Use only correct tools.

WARNING

• Do not strike the flywheel with a hammer or hard object because the flywheel may

later shatter during operation.

• Do not tamper with governor spring, links or other parts to increase engine speed.

SPARK PLUG: Use only Briggs & Stratton Spark Tester

(part number 19368) to check for spark.

In some areas, local law requires using resistor spark plug to

suppress ignition signals. If this engine was originally

equipped with resistor spark plug, use same type for

replacement.

MUFFLER

Replacement parts for the

muffler must be the same and

installed in the same position

as the original parts, other-

wise fire can occur.

If muffler is equipped with spark arrester screen, remove

screen for inspection. Replace screen if damaged or

plugged.

WARNING

FUEL SYSTEM

WARNING

Replacement parts for fuel

system (cap, hoses, tanks,

filters, etc.) must be the same

as original parts, otherwise

fire can occur.

REPLACE IN-LINE FUEL FILTER (if equipped)

[1] Disconnect spark plug wire and keep away from

spark plug.

[2] Drain fuel tank or close fuel shut-off valve before

replacing fuel filter. Otherwise, fuel can leak out,

creating a fire/explosion hazard.

AIR COOLING SYSTEM

Over time debris may accumulate in cylinder cooling fins

and cannot be observed without partial engine disassem-

bly. We recommend that you have an authorized Briggs &

Stratton Service Dealer clean the air cooling system per

recommended intervals. Equally important is to keep top of

engine free from debris. See cleaning debris below.

VALVE CLEARANCE

Check valve clearance yearly. (See Tune-up Specifications

on page 6.)

MAINTENANCE

CLEANING DEBRIS

CAUTION: Do not use water to clean engine parts.

Water could contaminate fuel system. Use a brush

or dry cloth.

Engine parts should be kept

clean to reduce the risk of

overheating and ignition of

accumulated debris. This is

especially important if cutting

tall grass.

WARNING

Finger Guard

Linkage, Springs,

Controls

Muffler

Daily or before every use, clean grass, chaff or

accumulated debris from engine. Keep linkage, spring

and controls clean. Keep area around and behind

muffler free of any combustible debris.

On string trimmer applications, clean accumulated debris

at each refueling, sooner if needed.

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. (15 ml) of

engine oil into cylinder. Replace spark plug and crank

slowly to distribute oil.

[4] Clean engine of surface debris, chaff or grass.

WARNING

[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.

The California Air Resources Board (CARB), U.S.

EPA and B&S are pleased to explain the Emission

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

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 emis-

sion 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 emission 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

emission 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.

Small off-road engines are warranted relative to emission 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.

#3 1 '!4

As the small off-road engine owner, you are re-

sponsible for the performance of the required

maintenance listed in your Operating and Main-

tenance Instructions. B&S recommends that

you retain all your receipts covering mainte-

nance on your small off-road engine, but B&S

cannot deny warranty solely for the lack of re-

ceipts or for your failure to ensure the perfor-

mance 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 warranty repairs should be

completed in a reasonable amount of time, not

to exceed 30 days.

If you have any questions regarding your war-

ranty rights and responsibilities, you should con-

tact a B&S Service Representative at

1-414-259-5262.

The emission warranty is a defects warranty.

Defects are judged on normal engine perfor-

mance. The warranty is not related to an in-use

emission test.

set forth in the B&S Engine Warranty Policy.

B&S is not liable to cover failures of War-

ranted 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 inspec-

tion to the effect of “repair or replace as nec-

essary” shall be warranted as to defects for

the warranty period. Any Warranted Part

which is scheduled for replacement as re-

quired 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 perfor-

mance and durability may be used in the per-

formance of any maintenance or repairs.

The owner is responsible for the perfor-

mance of all required maintenance, as de-

fined in the B&S Operating and Maintenance

Instructions.

6. Consequential Coverage

Coverage hereunder shall extend to the fail-

ure of any engine components caused by

the failure of any Warranted Part still under

warranty.

Dispositions de la garantie de défectuosité du contrôle des émissions de Briggs & Stratton

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

juillet 2000, surveillez la période de conformité d'émission sur les étiquettes

Après le 1

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 110000 est 164 cc. Le remplacement du moteur portant le modèle de série 120000 est 190 cc.
