SAFETY
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 refueling 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 inches below top of
neck to allow for fuel expansion.
• Keep fuel 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 equipped fasteners.
• Do not crank engine with spark plug, air cleaner cartridge
or air cleaner cover removed.
• If fuel spills, wait until it evaporates before starting engine.
• If GASOLINE engine floods, set choke to OPEN/RUN
position, place throttle in FAST and crank until engine
starts.
WHEN OPERATING EQUIPMENT
• Do not tip engine or equipment at angle which causes
gasoline to spill.
• Do not choke carburetor to stop engine.
WARNING
Gaseous fuels are extremely flammable
and readily form explosive air-vapor mixtures at ambient temperatures.
IF YOU SMELL GAS:
• DO NOT start the engine.
• DO NOT actuate any electrical switches.
• DO NOT use the phone in the vicinity.
• Evacuate the area.
• Contact the gas supplier or fire department.
REMEMBER:
• LPG vapor is heavier than air and trends to collect in low
areas. NG vapor is lighter than air and tends to collect in
high areas. Both may travel to remote locations.
• Keep all flames, sparks, pilot lights, and other ignition
sources away from the area where the engine is operated
or repaired.
• DO NOT smoke when operating or repairing the engine.
• DO NOT store gasoline or other flammable vapors or
liquids in the vicinity of the engine.
• BEFORE doing any service work to the engine, shut off
the gas supply.
• After initial installation or servicing, check for gas leaks.
DO NOT use an open flame. Apply very soapy water or
leak test solution with a brush and look for bubbles.
• Keep the equipment and the area surrounding the engine
free of debris.
• Install the fuel system according to applicable fuel/gas
codes.
WHEN TRANSPORTING EQUIPMENT
• On GASOLINE engine, transport with fuel tank EMPTY or
with fuel shut-off valve OFF.
• On NATURAL / LIQUID PETROLEUM (LP) GAS
engines transport with fuel cylinder empty or valve
closed, or tank disconnected.
WHEN STORING GASOLINE OR EQUIPMENT WITH
FUEL IN TANK
• Store away from furnaces, stoves, water heaters or other
appliances that have pilot light or other ignition source
because they can ignite gasoline vapors.
WARNING
Wear eye protection when doing repair work.
Frostbite can result from skin/eye contact with
leaking LP liquid.
• Installation, adjustment and repair work should be done by a
qualified technician.
• Flexible supply lines should be checked regularly to make
sure they are in good condition. Replace damaged or
leaking components.

SAFETY
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.
WARNING
Rapid retraction of starter cord (kickback) will pull
hand and arm toward engine faster than you can
let go.
Broken bones, fractures, bruises or sprains could
result.
• When starting engine, pull cord slowly until resistance is
felt, then pull rapidly.
• Remove all external equipment/engine loads before
starting engine.
• Direct coupled equipment components such as, but not
limited to, blades, impellors, pulleys, sprockets, etc.,
must be securely attached.
WARNING
Running engines produce heat. Engine parts,
especially muffler, become extremely hot.
Severe thermal burns can occur on contact.
Combustible debris, such as leaves, grass,
brush, etc. can catch fire.
• Allow muffler, engine cylinder and fins to cool before
touching.
• 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-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.
WARNING
Rotating parts can contact or entangle hands,
feet, hair, clothing, or accessories.
Traumatic amputation or severe laceration can
result.
• Operate equipment with guards in place.
• Keep hands and feet away from rotating parts.
• Tie up long hair and remove jewelry.
• Do not wear loose-fitting clothing, dangling drawstrings or
items that could become caught.
WARNING
Engines give off carbon monoxide, an odorless,
colorless, poison gas.
Breathing carbon monoxide can cause nausea,
fainting or death.
• Start and run engine outdoors.
• Do not start or run engine in enclosed area, even if doors
or windows are open.
Unintentional start-up can result in entanglement, traumatic amputation, or laceration.
BEFORE PERFORMING ADJUSTMENTS OR REPAIRS
• Disconnect spark plug wire and keep it away from spark
plug.

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).
Torque values are derived at 3060 RPM; horsepower values
are derived at 3600 RPM. 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

Note: For practical operation, the horsepower loading should not
exceed 85% of rated horsepower. Engine power will decrease
3-1/2% for each 1,000 feet (300 meters) above sea level and 1%
for each 10° F (5.6° C) above 77° F (25° C). Engine will operate
satisfactorily at an angle up to 15°.
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 power). 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-to-engine variability. Due to manufacturing
and capacity limitations, Briggs & Stratton may substitute an
engine of higher rated power for this Series engine.

HIGH FLOW AIR CLEANER MAINTENANCE
Perform this maintenance every 25 hours or every season,
clean more often under dusty conditions or when airborne
debris is present. This filter is made of cotton, which is
different from a standard paper filter, therefore it MUST be
oiled.
[1] Remove clamp and pull air cleaner from intake
manifold.
[2] Remove as much dirt from the filter as possible.
[3] Using the High Flow Air Filter Cleaner Kit, Briggs &
Stratton part no. 5089D, spray the filter with cleaner.
Allow the solution to soak in to the filter for about 15
minutes.
CAUTION: Never use strong detergents, high
pressure water, or gasoline to clean this filter.
[4] Rinse the filter with warm water, inside first and then
outside. (Let the water run from the clean side to the
dirty side.)
[5] Allow the filter to dry completely. It is best to allow the
filter to dry naturally. Don’t use heat, this might shrink
the cotton.
[6] Use only air filter oil, such as the oil included in the
cleaning kit (P/N 5089D), to re-oil the filter.
WARNING
Never use motor oil, transmission fluid, WD40, or other
oils. Failure to follow instructions can cause fires
resulting in death or serious injury. Use only air filter oil
designed specifically for air filters.
[7] Spray the filter with oil, or pour small amount onto
each pleat and allow filter to stand for 20 minutes. The
filter is correctly oiled when the cotton changes from
white to the color of the oil.
CAUTION: DO NOT over-oil air filter, it will interfere
with engine performance and may cause engine
damage. If the filter is placed on cardboard for 10
minutes and leaves a stain, it is over oiled. Wash/clean
and re-oil per above instructions.

BRIGGS & STRATTON ENGINE OWNER WARRANTY POLICY
Effective 12/06
LIMITED WARRANTY
Briggs & Stratton Corporation will repair or replace, free of charge, any part(s) of the engine that is defective in material or workmanship or both.
Transportation charges on product submitted for repair or replacement under this warranty must be borne by purchaser. This warranty is effective
for and is subject to the time periods and conditions stated below. For warranty servic e, find the neare st Authorized Serv ice Dealer in our
dealer locator map at www.briggsandstratton.com, or by calling (800) 233-3723, or as listed in the ‘Yellow Pages™’.
There is no other express warranty, implied warranties, including those of merchantability and fitness for a particular purpose, are
limited to one year from purchase, or to the extent permitted by law any and all implied warranties are excluded. Liability for incidental
or consequential damages are excluded to the extent exclusion is permitted by law. Some states or countries do not allow limitations on how
long an implied warranty lasts, and some states or countries do not allow the exclusion or limitation of incidental or consequential damages, so the
above limitation and exclusion may not apply to you. This warranty gives you specific legal rights and you may also have other rights which vary
from state to state and country to country.
WARRANTY TERMS **
Brand /Product Type Consumer Use Commercial Use
Vanguard 2 years 2 years
Extended Life Series, I / C, Intek I/ C, Intek Pro 2 years 1 year
Kerosene Fuel Operated Engines 1 year 90 days
All Other Briggs & Stratton Engines 2 years 90 days
** Engines used on Home Standby Generator applications are warranted under consumer use only. This warranty does not
apply to engines on equipment used for prime power in place of a utility. Engines used in competitive racing or on
commercial or rental tracks are not warranted.
The warranty period begins on the date of purchase by the first retail consumer or commercial end user, and continues for the period of time stated in
the table above. “Consumer use” means personal residential household use by a retail consumer. “Commercial use” means all other uses, including
use for commercial, income producing or rental purposes. Once an engine has experienced commercial use, it shall thereafter be considered as a
commercial use engine for purposes of this warranty.
No warranty registration is necessary to obtain warranty on Briggs & Stratton Products. Save your proof of purchase
receipt. If you do not provide proof of the initial purchase date at the time warranty service is requested, the manufacturing
date of the product will be used to determine the warranty period.
ABOUT YOUR 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
(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 service 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

Emissions Control System Warranty Statement
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 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
(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

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 Emissions Standard must display information regarding
the Emissions Durability Period and the Air Index. Briggs & Stratton
makes this information available to the consumer on our emissions
labels. The engine emissions 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 emissions compliant for 125 hours of actual
engine running time.
Intermediate:
Engine is certified to be emissions compliant for 250 hours of actual
engine running time.
Extended:
Engine is certified to be emissions 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 emissions
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 emissions 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
