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  
before removing gas cap.  
are flammable.  
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.  
WARNING  
WHEN STARTING ENGINE  
Rapid retraction of starter cord (kickback) will pull  
hand and arm toward engine faster than you can let  
go.  
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.  
Broken bones, fractures, bruises or sprains could  
result.  
If engine floods, set choke to OPEN/RUN position, place  
throttle in FAST and crank until engine starts.  
When starting engine, pull cord slowly until resistance is  
felt, then pull rapidly.  
WHEN OPERATING EQUIPMENT  
Do not tip engine or equipment at angle which causes  
gasoline to spill.  
Remove all external equipment/engine loads before  
starting engine.

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  
cap while the engine is hot or running. Severe  
thermal burns or injury can occur by escaping  
steam or hot engine coolant.  
Unintentional sparking can result in fire or  
electric shock.  
Unintentional start-up can result in entangle-  
ment, traumatic amputation, or laceration.  
Before Performing Adjustments or Repairs  
Disconnect spark plug wire and keep it away from spark  
plug.  
Stop engine and allow to cool before removing radiator or  
reservoir cap.

Disconnect battery at negative terminal (only engines  
cloth over cap and remove it slowly.  
with electric start).  
To remove radiator cap after engine is cool, place a thick  
cloth over cap and rotate it slowly counter-clockwise to  
the first stop. Pressurized steam may emit from the cap,  
stand back to avoid injury. Once all pressure is released,  
rotate cap counter-clockwise while pushing down on cap  
to remove.  
When Testing For Spark  
Use approved spark plug tester.  
Do not check for spark with spark plug removed.  
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.

stand back to avoid injury. Once all pressure is released,  
rotate cap counter-clockwise while pushing down on cap  
to remove.  
[4] Start and run engine for 30 seconds.  
[5] Shut engine off and allow it to cool. Recheck coolant levels in  
radiator and reservoir.  
CAUTION: Used coolant is a hazardous waste product.  
Dispose of used coolant properly. Check with your local  
authorities, service center, or dealer for safe disposal/re-  
cycling facilities.  
[6] Coolant level in reservoir should be between FULL and LOW  
when engine is cold.  
Normal coolant temperature  
gauge (if equipped) should  
read between 175° and 195° F

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.

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 GARDmay 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

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

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.

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.
