SAFETY
WARNING
Fuel and its vapors are extremely flammable and explosive.
Fire or explosion can cause severe burns
or death.
WHEN ADDING FUEL
• Turn engine OFF and let engine cool at least 2 minutes
before removing fuel 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 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 muffler, fuel cap and air cleaner are in place.
• If fuel spills, wipe it off before starting engine.
WHEN OPERATING EQUIPMENT
• Do not tip engine or equipment at angle which causes fuel to
spill.
WHEN TRANSPORTING EQUIPMENT
• Transport with fuel tank EMPTY or with fuel shut-off valve
OFF.
WARNING
Running engines produce heat. Engine
parts, especially turbocharger and
muffler, become extremely hot.
Severe thermal burns can occur on
contact.
Combustible debris, such as leaves,
grass, brush, etc. can catch fire.
• Allow muffler, turbocharger, 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, brushcovered 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
Rotating parts can contact or entangle
hands, feet, hair, clothing, or accessories.
Traumatic amputation or severe laceration can result.
WHEN STORING FUEL 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 equipment with stored fuel or fuel
source.
WARNING
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.
• 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.

SAFETY
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.
WARNING
Never remove radiator cap or radiator reservoir
cap while the engine is hot or running. Severe
thermal burns or injury can occur by escaping
steam or hot engine coolant.
• Stop engine and allow to cool before removing radiator or
reservoir cap.
• To remove reservoir cap after engine is cool, place a thick
cloth over cap and remove it slowly.
• To remove radiator cap after engine is cool, place a thick
cloth over cap and rotate it slowly counter-clockwise to
the first stop. Pressurized steam may emit from the cap,
stand back to avoid injury. Once all pressure is released,
rotate cap counter-clockwise while pushing down on cap
to remove.
WARNING
Unintentional sparking can result in fire
or electric shock.
Unintentional start-up can result in
entanglement, traumatic amputation,
or laceration.

REPAIRS
• Disconnect battery at negative terminal.
WARNING
Briggs & Stratton does not approve or authorize the use of
these engines on 3-wheel All Terrain Vehicles (ATVs), motor
bikes, fun/recreational go-karts, aircraft products or vehicles
intended for use in competitive events. Use of these engines in
such applications could result in property damage, serious
injury (including paralysis), or even death.
ENGINE INFORMATION
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-to-engine variability. Due to manufacturing and
capacity limitations, Briggs & Stratton may substitute an engine of
higher rated power for this Series engine.

ABOUT YOUR ENGINE WARRANTY
B&S welcomes warranty repair and apologizes to you for being
inconvenienced. Any Authorized Briggs & Stratton 3/LC 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
the 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
the equipment to which the engine may be mounted. Nor
does the warranty extend to repairs required because of:
1. Engines that are not properly applied to equipment. It is
strongly recommended that the factory be contacted prior
to applying a B&S 3/LC engine to equipment that did not
originally use a B&S 3/LC engine.
2. PROBLEMS CAUSED BY PARTS THAT ARE NOT
ORIGINAL BRIGGS & STRATTON PARTS.
3. Equipment controls or installations that prevent starting,
cause unsatisfactory engine performance, or shorten
engine life. (Contact equipment manufacturer.)
4. Leaking carburetors, clogged fuel pipes or injectors,
sticking valves, contaminated injection pumps, or other
damage, caused by using contaminated or stale fuel. Use
clean, fresh fuel (lead free gasoline, diesel fuel) and Briggs
& Stratton fuel stabilizer, Part No. 5041.
5. 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 oil and oil filter 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.
, and not replacement or refund of
6. Repair or adjustment of associated parts or assemblies
such as clutches, transmissions, remote controls, etc.,
which are not manufactured by B&S.
7. 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, replace
cartridge.) Read Operating & Maintenance Instructions.
8. Parts damaged by over-speeding, or overheating caused
by grass, debris, or dirt, which plugs, clogs radiator or air
cooling access openings, or damage caused by operating
the engine in a confined area without sufficient ventilation.
Engine damage caused by not using accurate mix of
anti-freeze and tap water, or water entering the engine due
to any cause.
9. 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.
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 is available only through service dealers which
have been authorized by Briggs & Stratton. Locate your
