Safety

Gasoline 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 the 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.

•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.

•Do not crank engine with spark plug removed.

•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

Starting engine creates sparking.

Sparking can ignite nearby flammable

gases.

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.

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

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.

•When starting engine, pull the starter 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, impellers, pulleys,

sprockets, etc., must be securely attached.

WARNING

Rotating parts can contact or entangle

hands, feet, hair, clothing, or

accessories.

Traumatic amputation or severe

laceration can result.

•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.

WARNING

Safety

www.BRIGGSandSTRATTON.com

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.

•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.

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.

•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

removed.

Unintentional sparking can result in

fire or electric shock.

Unintentional start-up can result in

entanglement, traumatic amputation,

or laceration.

Oil Capacity

Model 120000 and 150000 series engines:

20 ounces (0.6 liter).

Model 200000 and 210000 series engines:

28 ounces (0.8 liter).

Oil Recommendation

•Do not use special additives.

•Choose a viscosity from the following chart.

SAE 30 40

F and higher (5

C and higher)

is good for all purpose use above 40°F, use below

40°F will cause hard starting.

10W-30 0to100

F (--18 to 38

is better for varying temperature conditions. This

grade of oil improves cold weather starting, but may

increase oil consumption at 80°F(27°C) or higher.

Check oil level frequently at higher temperatures.

Synthetic 5W-30 --20 to 120

F (--30 to 40

provides the best protection at all temperatures as

well as improved starting with less oil consumption.

5W-30 40

F and below (5

C and below)

is recommended for winter use, and works best in

cold conditions.

If this engine is equipped with a gear reduction

unit, the gear reduction case must be filled with oil

prior to operating the engine. See “How To Change

The Gear Reduction Oil” in the Maintenance

Section.

CAUTION

Check/Add Oil

Before adding or checking the oil

•Place engine level.

•Clean the oil fill area of any debris.

Fuel Recommendations

This engine is certified to operate on gasoline. The

emissions control system for this engine is EM

(Engine Modifications).

Gasoline must meet these requirements:

•Clean, fresh, unleaded gasoline.

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

operating at high altitude, see below.

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

to 15% MTBE (methyl tertiary butyl ether), is

acceptable.

•Use of any gasoline not consistent with the

requirements will void the engine warranty.

In some local areas, fuel pumps may be marked if the

gasoline contains alcohols or ethers. If you are unsure

about the gasoline you purchase, check with your fuel

provider.

•Do not modify the engine fuel system or

carburetor to run on alternative fuels.

•Never mix oil with gasoline.

All gasoline is not the same. If you experience starting

or performance problems after new gasoline has been

used in your engine, switch to a different fuel provider

or change fuel brands.

Some fuels, called oxygenated or reformulated fuels,

are fuels blended with alcohols or ethers. Excessive

amounts of these blends can damage the fuel

system or cause performance problems. If any

undesirable operating symptoms occur, use gasoline

with a lower percentage of alcohol or ether.

CAUTION

Fuel Stabilizer

To protect the fuel system from gum formation, mix in

a fuel preservative when adding fuel. Briggs &

Stratton recommends using FRESH STARTtfuel

stabilizer, available as a liquid additive, concentrated

liquid cartridge or granular additive.

High Altitude use

At higher altitudes (over 5,000 feet), 85 octane/85 AKI

(89 RON) gasoline can be used. Operation at high

altitude may require a high-altitude carburetor jet kit to

improve performance and decrease fuel consumption.

See an Authorized Briggs & Stratton service dealer for

more information.

Add Fuel (Figure 4)

Gasoline and its vapors are

extremely flammable and explosive.

Fire or explosion can cause severe

burns or death.

•Turn engine off and let engine cool at least 2

minutes before removing the 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.
