The Power That Works For You.

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.

TheEmissions 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 290000 and

300000 engines is 480 cc, 350000 engines is

570 cc, and 380000 engines is 627 cc.

GENERAL INFORMATION

ENGINE MODEL

This is a twin cylinder, overhead valve (OHV), air-cooled

engine. It is a low emissions engine.

In the state of California, Model Series 290000, 300000,

350000 and 380000 engines are certified by the California

Air Resources Board to meet emissions standards for 250

hours. Such certification does not grant the purchaser,

owner or operator of this engine any additional warranties

with respect to the performance or operational life of this

engine. This engine is warranted solely according to the

product and emissions warranties stated elsewhere in this

manual.

Note:

For practical operation, the horsepower loading should not

exceed 85% of rated horsepower. Engine power will

decrease 3-1/2% for each 1,000 feet (300 meters) above

sea level and 1% for each 10°F (5.6°C) above 77°F (25°

C). It will operate satisfactorily at an angle up to 15°.

OIL

CAUTION: This engine is shipped from Briggs &

Stratton without oil. Check oil level before starting

engine. If you start the engine without oil, the engine

will be damaged beyond repair and will not be

covered under warranty.

OIL CAPACITY

Engine holds approximately 1-1/2 quarts (48 ounces or 1.4

liters) when changing oil and filter.

TYPE OF OIL TO USE

•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).

•Do not use special additives.

•Choose a viscosity according to the table opposite.

Note: Synthetic oil meeting ILSAC GF-2, API

certification mark and API service symbol

(shown at left) with “SJ/CF ENERGY CON-

SERVING”or higher, is an acceptable oil at all

temperatures. Use of synthetic oil does not

alter required oil change intervals.

°F-20 0 20 40 60 80 100

°C-30 -20 -10 0 10 20 30 40

STARTING TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE

*CAUTION: 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.

** CAUTION: SAE 30 oil, if used below 40°F (4°C),

will result in hard starting and possible engine bore

damage due to inadequate lubrication.

SAE Viscosity Grades

CHECKING AND ADDING OIL

•Check oil level before starting the engine.

•Check level daily, or after every eight (8) hours. •Keep oil level at FULL.

•Do not overfill.

[1] Place engine level.

Clean around oil fill and dipstick.

[2] Remove dipstick and

wipe clean with cloth.

[3] Then push dipstick back

in and remove to check

oil level.

Oil Fill

Dipstick

Oil checking procedure: before starting engine, check oil level.

Oil filling procedure: first add 1 quart (32 ounces or 1 liter). Start and run engine at idle for 30 seconds. Shut engine off and

wait 30 seconds. Then add more oil slowly to bring level to Full mark on dipstick.

FULL

ÏÏ

[4] Remove oil fill cap (if

equipped). Pour oil slowly. [5] Fill to FULL line on dip-

stick –recheck. [6] Replace dipstick firmly.

FULL

Document: - page 8 (Black)

Screen angle and frequency: 45.0000, 150.0000

[1] Remove cap. Fill tank to approximately 1-1/2

inches below top of neck to allow for fuel

expansion. Be careful not to overfill.

Briggs & Stratton Smart-fill)Fuel Can fills to

the correct level and automatically shuts off,

reducing spills and emissions.

[2] Replace cap before starting.

FUEL

TYPE OF FUEL TO USE

•Use clean, fresh, regular unleaded gasoline with a

minimum of 85 octane. Fresh fuel prevents gum from

forming in the fuel system or on essential carburetor parts.

Purchase fuel in quantity that can be used within 30 days.

•Do not use gasoline which contains Methanol.

•Do not mix oil with gasoline.

•For engine protection use Briggs & Stratton Gasoline

Additive available from your Authorized Briggs &

Stratton Dealer (P/N 5041 or single use pouch).

•The gasoline engine is certified to operate on gasoline.

Exhaust Emission Control System: EM (Engine

Modifications).

WARNING

•Turn engine OFF and let engine cool at least 2

minutes before removing gas cap.

•Fill fuel tank outdoors or in well-ventilated area.

•Keep gasoline away from sparks, open flames,

pilot lights, heat, and other ignition sources.

•If fuel spills, wait until it evaporates before

starting engine.

CAUTION: Some fuels, called oxygenated or

reformulated gasoline, are gasoline blended with

alcohols or ethers. Excessive amounts of these

blends can damage the fuel system or cause

performance problems. If any undesirable operat-

ing symptoms occur, use gasoline with a lower

percentage of alcohol or ether.

GASOLINE POWERED ENGINES NATURAL (NG) / LIQUID PROPANE (LPG)

GAS POWERED ENGINES

•Use clean, dry fuel, free of moisture or any particulate

material. Using fuels outside the following recom-

mended values may cause performance problems.

•In engines set up to run on LPG, commercial grade

HD5 LPG is recommended. Recommended fuel

composition is fuel with a minimum fuel energy of

2500 BTU’s/ft3with maximum propylene content of

5% and butane and heavier gas content of 2.5% and

minimum propane content of 90%.

•NG or LPG engines are certified to operate on natural

or liquid propane gas.

The equipment on which this engine is mounted is

equipped with an automatic safety gas “fuel

lock-off”valve. DO NOT operate the equipment if

the “fuel lock-off”valve is missing or inoperative.

WARNING

ADDING FUEL

GASOLINE POWERED ENGINES NATURAL (NG) / LIQUID PROPANE (LPG)

STARTING AND STOPPING

WARNING

•Do not use pressurized starting fluids.

•Vapors are flammable.

OIL PRESSURE SWITCH

If engine is equipped with an oil pressure switch, the switch

will either activate a warning device or stop the engine

when the engine runs low on oil. (Read the operating

instructions supplied by the equipment manufacturer to

determine how your engine is equipped.)

BEFORE STARTING –LPG / NG ENGINES

CAUTION:

When operating on LPG fuel, 12 volts

MUST be supplied to the connector.

When operating on NG fuel, 12 volts

MUST NOT be supplied to connector.

Failure to do so, may cause engine

damage.
