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 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-toengine variability. Due to manufacturing and capacity
limitations, Briggs & Stratton may substitute an engine
of higher rated power for this Series engine.
GENERAL INFORMATION

burns or death.
WHEN ADDING GASOLINE
• Turn engine OFF and let engine cool at least 2
minutes before refueling 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.
• 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.
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

• If engine floods, set choke to OPEN/RUN position,
place throttle in FAST and crank until engine starts.
WHEN OPERATING EQUIPMENT WITH
GASOLINE ENGINE
• Do not tip engine or equipment at angle which
causes gasoline to spill.
• Do not choke carburetor to stop engine.
WHEN TRANSPORTING EQUIPMENT
• Transport with fuel tank EMPTY or with fuel shut-off
valve OFF, and/or fuel tank empty.
WHEN STORING FUEL OR EQUIPMENT
• Store away from furnaces, stoves, water heaters or
other appliances that have pilot light or other ignition
source because they can ignite gaseous vapors.
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.
• Engine should be kept clean to reduce the risk of
overheating and ignition of accumulated debris.
Clean engine when it is cold, especially in the
muffler and manifold areas.
• 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 Public Resources
Code Section 4442 requires a spark arrester in
working order.) Other states may have similar
laws. Federal laws apply on federal land.
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, impellers, pulleys, sprockets, etc.,

OIL RECOMMENDATIONS
Fig. 2
Engine shipped from Briggs & Stratton without oil.
Before starting engine
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.).
Use no special additives with recommended oils. Do
not mix oil with gasoline.
Choose the SAE viscosity grade of oil from this chart
that matches the starting temperature anticipated
before the next oil change.
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.
* 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.
** SAE 30 oil, if used below 40° F (4° C), will result
in hard starting and possible engine bore
damage due to inadequate lubrication.

FUEL RECOMMENDATIONS
THE GASOLINE ENGINE IS CERTIFIED TO OPERATE ON GASOLINE. Exhaust Emission Control Sys-
tem: EM (Engine Modifications).
Use clean, fresh, lead-free
gasoline with a minimum of
85 octane. Leaded gasoline may be used if it is
commercially available and if unleaded is unavailable.
Purchase fuel in quantity that can be used within 30
days. See Storage.
In U.S.A. leaded gasoline may not be used. Some
fuels, called oxygenated or reformulated gasolines, are
gasolines blended with alcohols or ethers. Excessive
amounts of these blends can damage the fuel system
or cause performance problems. If any undesirable
operating symptoms occur, use gasoline with a lower
percentage of alcohol or ether.
Do not use gasoline which contains Methanol. Do not
mix oil with gasoline.
Check fuel level
WARNING
• Before refueling, allow engine to cool 2
minutes.
Clean around fuel fill before removing cap to refuel. Fill
tank to approximately 1-1/2 inches below top of neck to
allow for fuel expansion. Be careful not to overfill.

STORAGE
Gasoline engines stored over 30 days need to be
protected or drained of fuel to prevent gum from
forming in fuel system or on essential carburetor parts.
For gasoline engine protection, we recommend use of
Briggs & Stratton Fuel Stabilizer available from an
Authorized Briggs & Stratton Service Dealer. Mix
stabilizer with fuel in fuel tank or storage container. Run
engine for a short time to circulate stabilizer through
carburetor. Engine and fuel can be stored up to 24
months.
Note: If stabilizer is not used or if engine is operating on
gasoline containing alcohol, e.g. gasohol, remove all fuel
from tank and run engine until it stops from lack of fuel.

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.

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 Standards 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 walkbehind 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

ABOUT YOUR ENGINE WARRANTY
WARRANTY TERMS**
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.
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.
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/or replace the filter as stated in
the Operator’s Manual.
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.
