Storage

WARNING

Fuel and its vapors are extremely flammable and explosive.

Fire or explosion can cause severe burns or death.

When Storing Fuel Or Equipment With Fuel In Tank

• Store away from furnaces, stoves, water heaters or other appliances that have pilot

lights or other ignition sources because they can ignite fuel vapors.

Fuel System

See Figure: 19

Store the engine level (normal operating position). Fill fuel tank (A, Figure 19) with fuel.

To allow for expansion of fuel, do not overfill above the fuel tank neck (B).

Fuel can become stale when stored over 30 days. Stale fuel causes acid and gum deposits

to form in the fuel system or on essential carburetor parts. To keep fuel fresh, use Briggs

& Stratton Advanced Formula Fuel Treatment & Stabilizer, available wherever Briggs

& Stratton genuine service parts are sold.

There is no need to drain gasoline from the engine if a fuel stabilizer is added according

to instructions. Run the engine for two (2) minutes to circulate the stabilizer throughout the

fuel system before storage.

If gasoline in the engine has not been treated with a fuel stabilizer, it must be drained into

an approved container. Run the engine until it stops from lack of fuel. The use of a fuel

stabilizer in the storage container is recommended to maintain freshness.

Engine Oil

While the engine is still warm, change the engine oil. See the

Change Engine Oil

section.

Power Ratings: The gross power rating for individual gasoline engine models is labeled

in accordance with SAE (Society of Automotive Engineers) code J1940 Small Engine

Power & Torque Rating Procedure, and is rated in accordance with SAE J1995. Torque

values are derived at 2600 RPM for those engines with “rpm” called out on the label and

3060 RPM for all others; horsepower values are derived at 3600 RPM. The gross power

curves can be viewed at www.BRIGGSandSTRATTON.COM. Net power values are taken

with exhaust and air cleaner installed whereas gross power values are collected without

these attachments. Actual gross engine power will be higher than net engine power and

is affected by, among other things, ambient operating conditions and engine-to-engine

variability. Given the wide array of products on which engines are placed, the gasoline

engine may not develop the rated gross power when used in a given piece of power

equipment. This difference is due to a variety of factors including, but not limited to, the

variety of engine components (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 engine.

LookForRelevantEmissionsDurabilityPeriodandAirIndex

InformationOnYourSmallOff-RoadEngineEmissionsLabel

Engines that are certified to meet the California Air Resources Board (CARB) small off-

road Emissions Standard 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 Operator's Manual. The following categories are used:

Moderate:

Engines at or less than 80 cc displacement are certified to be emissions compliant for 50

hours of actual engine running time. Engines greater than 80 cc displacement are certified

to be emissions compliant for 125 hours of actual engine running time.

Intermediate:

Engines at or less than 80 cc displacement are certified to be emissions compliant for 125

hours of actual engine running time. Engines greater than 80 cc displacement are certified

to be emissions compliant for 250 hours of actual engine running time.

Extended:

Engines at or less than 80 cc displacement are certified to be emissions compliant for 300

hours of actual engine running time. Engines greater than 80 cc displacement are certified

to be emissions 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.

Briggs & Stratton engines are certified to meet the United States Environmental Protection

Agency (USEPA) Phase 2 or Phase 3 emissions standards. 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atorlessthan80ccdisplacement:

Category C = 50 hours, Category B = 125 hours, Category A = 300 hours

Forenginesgreaterthan80ccdisplacementandlessthan225ccdisplacement:
