_, 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

The Power That Works For You.TM

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 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 110000 engine is 190 cc, Model Series 120000 engine is 206 cc, Model Series 200000

engine is 305 cc, Model Series 210000 engine is 342 cc.

ofthe emission labeltypically
found on a certified engine.

I '_ _I BEFORE OPERATING ENGINE

• Read entire Operating & Maintenance Instructions AND
the instructions for the equipment this engine powers.*

• Failure to follow instructions could result in serious injury
or death.

275092

THE OPERATING & MAINTENANCE INSTRUCTIONS
CONTAIN SAFETY INFORMATION TO

• Make you aware of hazards associated with engines

• Inform you of the risk of injury associated with those hazards, and

• Tell you how to avoid or reduce the risk of injury.

\

The safety alert symbol _m, lL ) is used to identify safety
information about hazards that can result in personal injury.

A signal word (DANGER, WARNING, or CAUTION) is
used with the alert symbol to indicate the likelihood and the

potential severity of injury. In addition, a hazard symbol
may be used to represent the type of hazard.

_k DANGER indicates a hazard which, if not

avoided, will result in death or serious injury.

_, WARNING indicates a hazard which, if not

avoided, could result in death or serious injury.

CAUTION indicates a hazard which, if not

avoided, might result in minor or moderate
injury.

CAUTION, when used without the alert symbol,

indicates a situation that could result in damage
to the engine.

WARNING

The engine exhaust from this prod-

uct contains chemicals known to the
State of California to cause cancer,

birth defects, or other reproductive
harm.

and understand the operating instructions for the equipment on which your engine is placed.

SAFETY [B,, Gs STRA O.]

, WARNING

WHEN ADDING FUEL

• 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.

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.

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

• Transport with fuel tank EMPTY or with fuel shut-off

valve OFF.

WHEN STORING GASOLINE 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 gasoline

vapors.

, WARNING

• If there is natural or LP gas leakage in area, do not
start engine.

• Do not use pressurized starting fluids because
vapors are flammable.

, WARNING

• 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.

, WARNING

• 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.

I B. GS ST.A O.JSAFETY

WARNING

• Start and run engine outdoors.

• Do not start or run engine in enclosed area, even if

doors or windows are open.

WARNING

i

• Allow muffler, 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, brush-covered 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.

BEFORE PERFORMING ADJUSTMENTS OR
REPAIRS

• Disconnect spark plug wire and keep it away from
spark plug.

• Disconnect battery at negative terminal (only
engines with electric start).

WHEN TESTING FOR SPARK

• Use approved spark plug tester.

• Do not check for spark with spark plug removed.

TECHNICAL INFORMATION

POWER RATINGS: The power ratings for an individual engine

model are initially developed by starting with SAE (Society of Auto-
motive 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 en-

vironmental 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 "on-
site" 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, maxi-

mum governed engine speed, individual engine to engine variabil-
ity, 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 wil! therefore not necessarily match the

values derived using the foregoing codes.
