Safety Information
WARNING
WARNING
Gaseous fuels, such as liquid
petroleum gas (LPG) and natural
gas (NG), are extremely flammable
and can readily form explosive
air-vapor mixtures at moderate
temperatures.
Gasoline and its vapors are extremely
flammable and explosive.
Fire or explosion can cause severe
burns or death.
WHEN ADDING FUEL
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:
• 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.
• 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
• LPG vapor is heavier than air and tends to
collect in low areas. NG vapor is lighter then
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.
• Make sure spark plug, muffler, fuel cap and
air cleaner are in place.
• Do not crank engine with spark plug

WARNING
1. To prevent gum from forming in fuel system or on
essential carburetor parts:
When storing gasoline or equipment with fuel
in the tank:
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.
• Store away from furnaces, stoves, water
heaters, or other appliances that have a
pilot light or other ignition source because
they can ignite gasoline vapors.
If fuel tank contains gasoline either run engine until it
stops from lack of fuel or add a gasoline additive. If you
use a gasoline 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.
2. While engine is still warm, change oil.
When Transporting Equipment:
• Transport with fuel tank EMPTY or with
fuel shut-off valve OFF.

Technical Information
Engine Power Rating Information
Specifications
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). 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 horsepower). 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
We recommend that you use an authorized Briggs &
Stratton Service Dealer for all maintenance and service
of the engine and engine parts. Use only genuine
Briggs & Straton parts.

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.
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.
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.
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.
Normal wear:
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
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:
recommended intervals.) Read Operating &
Maintenance Instructions.
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.
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.
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:
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.
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.)
Warranty 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™” of your
telephone directory under “Engines, Gasoline” or
“Gasoline Engines,” “Lawn Mowers,” or similar
