When Adding Fuel

•Turn engine off and let engine cool at least 2

minutes before removing the fuel cap.

•Fill fuel tank outdoors or in well-ventilated

area.

•Do not overfill fuel tank. Fill tank to

approximately 1.5 inches (38 mm) 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.

•If fuel spills, wait until it evaporates before

starting engine.

When Starting Engine

•Ensure that spark plug, muffler, fuel cap and

air cleaner are in place and secured.

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

Gasoline and its vapors are extremely

flammable and explosive.

Fire or explosion can cause severe burns or

death.

Starting engine creates sparking.

Sparking can ignite nearby flammable gases.

Explosion and fire could result.

WARNING

•If there is natural or LP gas leakage in area,

do not start engine.

Operator Safety

Rapid retraction of starter cord (kickback) will

pull hand and arm toward engine faster than

you can let go.

Broken bones, fractures, bruises or sprains

could result.

WARNING

•When starting engine, pull the starter cord

slowly until resistance is felt and then pull

rapidly to avoid kickback.

•Remove all external equipment/engine loads

before starting engine.

•Direct-coupled equipment components such

as, but not limited to, blades, impellers,

pulleys, sprockets, etc., must be securely

attached.

Rotating parts can contact or entangle hands,

feet, hair, clothing, or accessories.

Traumatic amputation or severe laceration can

result.

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.

Running engines produce heat. Engine parts,

especially muffler, become extremely hot.

Severe thermal burns can occur on contact.

Combustible debris, such as leaves, grass,

brush, etc. can catch fire.

WARNING

•Allow muffler, engine cylinder and fins to cool

before touching.

•Remove accumulated debris 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.

Unintentional sparking can result in fire or

electric shock.

Unintentional start-up can result in

entanglement, traumatic amputation, or

laceration.

Fire hazard

WARNING

Before performing adjustments or repairs:

•Disconnect the spark plug wire and keep it

away from the spark plug.

•Disconnect battery at negative terminal (only

engines with electric start.)

•Use only correct tools.

•Do not tamper with governor spring, links or

other parts to increase engine speed.

•Replacement parts must be the same and

installed in the same position as the original

parts.

•Do not strike the flywheel with a hammer or

hard object because the flywheel may later

shatter during operation.

When testing for spark:

•Use approved spark plug tester.

•Do not check for spark with spark plug

Oil Recommendations

We recommend the use of Briggs & Stratton Warranty

Certified oils for best performance. Other high-quality

detergent oils are acceptable if classified for service SF, SG,

SH, SJ or higher. Do not use special additives.

Outdoor temperatures determine the proper oil viscosity for

the engine. Use the chart to select the best viscosity for the

outdoor temperature range expected.

Note: Synthetic oil meeting ILSAC GF-2, API

certification mark and API service symbol

(shown at left) with “SJ/CF ENERGY

CONSERVING” or higher, is an acceptable oil

at all temperatures. Use of synthetic oil does

not alter required oil change intervals.

Fuel Recommendations

Fuel must meet these requirements:

•Clean, fresh, unleaded gasoline.

•A minimum of 87 octane/87 AKI (91 RON). High altitude

use, see below.

•Gasoline with up to 10% ethanol (gasohol) or up to

15% MTBE (methyl tertiary butyl ether) is acceptable.

CAUTION: Do not use unapproved gasolines, such as E85.

Do not mix oil in gasoline or modify the engine to run on

alternate fuels. This will damage the engine components

and void the engine warranty.

To protect the fuel system from gum formation, mix a fuel

stabilizer into the fuel. See Storage. All fuel is not the same.

If starting or performance problems occur, change fuel

providers or change brands. This engine is certified to

operate on gasoline. The emissions control system for this

engine is EM (Engine Modifications)

High Altitude

At altitudes over 5,000 feet (1524 meters), a minimum 85

octane/85 AKI (89 RON) gasoline is acceptable. To remain

emissions compliant, high altitude adjustment is required.

Operation without this adjustment will cause decreased

performance, increased fuel consumption, and increased

emissions. See a Briggs & Stratton Authorized Dealer for

high altitude adjustment information.

Operation of the engine at altitudes below 2,500 feet (762

meters) with the high altitude kit is not recommended.
