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 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.
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 190000 engines is 319 cc. The displacement of Model Series 280000 engines is
465 cc.

SAFETY
WARNING
WARNING
Starting engine creates sparking.
Gasoline and its vapors are extremely
flammable and explosive.
Sparking can ignite nearby flammable
gases.
Fire or explosion can cause severe burns
or death.
Explosion and fire could result.
WHEN ADDING FUEL
• If there is natural or LP gas leakage in area, do not
start engine.
• Do not use pressurized starting fluids because
vapors are flammable.
• 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.
WARNING
Rapid retraction of starter cord (kickback) will
pull hand and arm toward engine faster than
you can let go.
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.
• If engine floods, set choke to OPEN/RUN position,
place throttle in FAST and crank until engine starts.
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.
WHEN OPERATING EQUIPMENT
• Do not tip engine or equipment at angle which
causes gasoline to spill.
• Do not choke carburetor to stop engine.
WHEN TRANSPORTING EQUIPMENT
WARNING
• Transport with fuel tank EMPTY or with fuel shut-off
valve OFF.
Rotating parts can contact or entangle
hands, feet, hair, clothing, or accessories.
WHEN STORING GASOLINE OR EQUIPMENT
WITH FUEL IN TANK
Traumatic amputation or severe laceration
can result.
• Store away from furnaces, stoves, water heaters or
other appliances that have pilot light or other
ignition source because they can ignite gasoline
vapors.
• Operate equipment with guards in place.
• Keep hands and feet away from rotating parts.

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 “onsite” 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, 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.

*
CAUTION: 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.
** CAUTION: SAE 30 oil, if used below 40° F (4° C), will
result in hard starting and possible engine bore
damage due to inadequate lubrication.
• Use a high quality detergent oil classified “For Service
SF, SG, SH, SJ” or higher, such as Briggs & Stratton
30W, Part Number 100005 (20 oz) or 100028 (48 oz).
• Do not use special additives.
• Choose a viscosity according to the table opposite.
Note: Synthetic oil meeting ILSAC GF-2, API
certification mark and API service symbol
(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.
CHECKING AND ADDING OIL
• Check oil level before starting the engine.
• Check level daily, or after every eight (8) hours.
• Keep oil level at FULL.
• Do not overfill.

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
WARNING
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.

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.

EMISSION CONTROL WARRANTY COVERAGE IS APPLICABLE TO CERTIFIED ENGINES PURCHASED IN CALIFORNIA IN 1995 AND THEREAFTER, WHICH ARE USED IN CALIFORNIA, AND TO CERTIFIED MODEL YEAR 1997 AND LATER ENGINES WHICH ARE PURCHASED AND
USED ELSEWHERE IN THE UNITED STATES (AND AFTER JANUARY 1, 2001 IN CANADA).

The California Air Resources Board (CARB), U.S.
EPA and B&S are pleased to explain the Emission
Control System Warranty on your model year
2002 and later small off-road engine (SORE). In
California, new small off-road engines 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 emission 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 system, 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.
! &! !! ) / " 1 !0
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 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 emission warranty is a defects warranty.
Defects are judged on normal engine performance. The warranty is not related to an in-use
emission test.
