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 perfor-
mance 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 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 condi-
tions (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.
The safety alert symbol is used to identify safety
information about hazards that can result in personal
injury.

WARNING
Rapid retraction of starter cord (kickback)
will pull hand and arm toward engine
faster than you can let go.
Rotating parts can contact or entangle
hands, feet, hair, clothing, or accessories.
Traumatic amputation or severe lac-
eration can result.
Fuel and its vapors are extremely
flammable and explosive.
Fire or explosion can cause severe

WHEN ADDING GASOLINE
• When starting engine, pull cord slowly until resistance is
felt, then pull rapidly.
• Turn engine OFF and let engine cool at least 2
minutes before refueling engine.
• Remove all external equipment/engine loads before
starting engine.
• 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.
• Direct coupled equipment components such as, but not
limited to, blades, impellers, pulleys, sprockets, etc.,
must be securely attached.
OIL RECOMMENDATIONS
• Keep gasoline away from sparks, open flames, pilot
lights, heat, and other ignition sources.

30W, Part Number 100005 (20 oz.) or 100028 (48 oz.).
Use no special additives with recommended oils. Do
not mix oil with gasoline.
• Do not crank engine with spark plug removed.
• If fuel spills, wait until it evaporates before starting
engine.
Breathing carbon monoxide can cause
nausea, fainting or death.
Choose the SAE viscosity grade of oil from this chart
that matches the starting temperature anticipated
before the next oil change.
• If engine floods, set choke to OPEN/RUN position,
place throttle in FAST and crank until engine starts.
• Start and run engine outdoors in a well ventilated
area.
WHEN OPERATING EQUIPMENT WITH
GASOLINE ENGINE
• Do not start or run engine in enclosed area, even if
doors or windows are open.
Note: Synthetic oil meeting ILSAC
GF-2, API certification mark and API ser-
vice 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.
• 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, and/or fuel tank empty.
Unintentional sparking can result in
fire or electric shock.
WHEN STORING FUEL OR EQUIPMENT
*
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-vis-
cosity oil, check oil level more frequently.
• Store away from furnaces, stoves, water heaters or
other appliances that have pilot light or other ignition
source because they can ignite gaseous vapors.
Unintentional start-up can result in
entanglement, traumatic amputation,
or laceration.
BEFORE PERFORMING ADJUSTMENTS
OR REPAIRS
** SAE 30 oil, if used below 40° F (4° C), will result
in hard starting and possible engine bore
damage due to inadequate lubrication.
• Disconnect battery at negative (−) terminal.
• Disconnect spark plug wire and keep it away from
spark plug.

Look For Relevant Emissions
Durability Period and
Air Index Information On
Your Engine Emissions Label
The following are specific provisions relative to your Emis-
sions 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.
Environmental Protection Agency (U.S. EPA)
Emissions Control System Warranty Statement
(Owner’s Defect Warranty Rights and Obligations)
Engines that are certified to meet the California Air Re-
sources Board (CARB) Tier 2 Emissions Standards must
display information regarding the Emissions Durability
Period and the Air Index. Briggs & Stratton makes this in-
formation available to the consumer on our emissions la-
bels. The engine emissions label will indicate certification
information.
1. Warranted Parts
California, United States and Canada Emissions
Control Defects Warranty Statement
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.
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, ne-
glect or improper maintenance of your small off-road en-
gine.
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 diagno-
sis, parts and labor.
a. Fuel Metering System
•
•
•
•
•
•
Cold start enrichment system (soft choke)
Carburetor and internal parts
Fuel pump
The Emissions Durability Period describes the number
of hours of actual running time for which the engine is cer-
tified to be emissions compliant, assuming proper mainte-
nance in accordance with the Operating & Maintenance
Instructions. The following categories are used:
Fuel line, fuel line fittings, clamps
Fuel tank, cap and tether
Carbon canister
b. Air Induction System
Moderate:
Engine is certified to be emissions compliant for 125 hours
of actual engine running time.
•
•
•
Air cleaner
Intake manifold
Purge and vent line
Intermediate:
Engine is certified to be emissions compliant for 250 hours
of actual engine running time.
c. Ignition System
•
•
Spark plug(s)
Magneto ignition system
d. Catalyst System
Extended:
•
•
•
Catalytic converter
Exhaust manifold
Air injection system or pulse valve
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. There-
fore, the Emissions Durability Period of an engine with
an intermediate rating would equate to 10 to 12 years.
Briggs & Stratton Emissions Control
Defects Warranty Coverage
e. Miscellaneous Items Used in Above Systems
•
Vacuum, temperature, position, time sensitive
valves and switches
Connectors and assemblies
Small off-road engines are warranted relative to emis-
sions control parts defects for a period of two years, sub-
ject to provisions set forth below. If any covered part on
your engine is defective, the part will be repaired or re-
placed by B&S.
Certain Briggs & Stratton engines will be certified to meet
the United States Environmental Protection Agency
(USEPA) Phase 2 emissions standards. For Phase 2 cer-
tified engines, the Emissions Compliance Period referred
to on the Emissions Compliance label indicates the num-
ber of operating hours for which the engine has been
shown to meet Federal emissions requirements.
•
2. Length of Coverage
B&S warrants to the initial owner and each subsequent
purchaser that the Warranted Parts shall be free from de-
fects in materials and workmanship which caused the fail-
ure of the Warranted Parts for a period of two years from
the date the engine is delivered to a retail purchaser.
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 rec-
ommends that you retain all your receipts covering main-
tenance on your small off-road engine, but B&S cannot
deny warranty solely for the lack of receipts or for your fail-
ure to ensure the performance of all scheduled mainte-
nance.
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

ABOUT YOUR ENGINE WARRANTY
Briggs
&
Stratton welcomes warranty repair and
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.
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 and 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.
5. Repair or adjustment of associated parts or
assemblies such as clutches, transmissions, remote
controls, etc., which are not manufactured by Briggs
& Stratton.
air cleaner element or cartridge. At recommended
intervals, clean and/or replace the filter as stated in
the Operator’s Manual.
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.
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 engine of debris at
recommended intervals as stated in the Operator’s
Manual.
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 authorized
service dealers by Briggs & Stratton Corporation.

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,
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
