SAFETY
WARNING
WARNING
Gasoline and its vapors are extremely flam-
mable and explosive.
Starting engine creates sparking.
Sparking can ignite nearby flammable gases.
Explosion and fire could result.
Fire or explosion can cause severe burns or
death.
WHEN ADDING FUEL
• If there is natural or LP gas leakage in area, do not start
engine.
• Turn engine OFF and let engine cool at least 2 minutes
• Do not use pressurized starting fluids because vapors

SAFETY
WARNING
WARNING
Running engines produce heat. Engine parts,
especially muffler, become extremely hot.
Engines give off carbon monoxide, an odorless,
colorless, poison gas.
Severe thermal burns can occur on contact.
Breathing carbon monoxide can cause nausea,
fainting or death.
Combustible debris, such as leaves, grass,
brush, etc. can catch fire.
• Start and run engine outdoors.
• Allow muffler, engine cylinder and fins to cool before
touching.
• Do not start or run engine in enclosed area, even if doors
or windows are open.
• Remove accumulated combustibles from muffler area
and cylinder area.
• Install and maintain in working order a spark arrester
before using equipment on forest-covered, grass-cov-
ered, 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
WARNING
Never remove radiator cap or radiator reservoir

ENGINE INFORMATION
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.

MANUFACTURING DATE OF THE PRODUCT WILL BE USED TO DETERMINE THE WARRANTY PERIOD.
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.
the engine because of improper maintenance, is not covered
by warranty.
intervals, clean and re−oil the Oil−Foamelement or the
foam pre−cleaner, and replace the cartridge.) Read
Operating & Maintenance Instructions.
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
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.
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 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.
Briggs & Stratton Emission Control Defects Warranty Provisions
The following are specific provisions relative to your Emission 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
2. Length of Coverage
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.
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.
Coverage under this warranty extends only
to the parts listed below (the emission con-
trol systems parts) to the extent these parts
were present on the engine purchased.
5. Maintenance
a. Fuel Metering System
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.

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.
Lapériode 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
Intermédiaire
Prolongé
le moteur est certifié conforme pour 125 heures d’utilisation normale.
le moteur est certifié conforme pour 250 heures d’utilisation normale.
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.
er
À compter du 1 juillet 2000, surveillez la période de conformité d’émission sur les étiquettes
er
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.
