I, General Safety Precautions • NEVER fillfuel tank indoors.Fillfuel tank outdoors

in a well-ventilated area.

Read equipmentmanufacturer's manual andthis

materialthoroughly before usingthis engine. Failure to

do socanresultinseriousinjuryordeath. CallTecumseh

Power Company at 1-800-558-5402 or visit

www.TecumsehPower.com ifyou have anyquestions.

A. Avoid Carbon Monoxide Poisoning

Allengine exhaust contains

carbon monoxide, a deadly

gas. Breathingcarbon

monoxidecan cause

headaches, dizziness,

drowsiness,nausea,confusion

and eventuallydeath.

Carbon monoxideis a colorless,odorless, tasteless gas

whichmay be present even if you do not see or smell any

engine exhaust. Deadly levels of carbon monoxidecan

collectrapidlyand you can quickly beovercome and

unable to save yourself. Also, deadly levels of carbon

monoxide can linger for hours or days in enclosed or

poorly-ventilated areas. If you experience any symptomsof

carbon monoxide poisoning, leave the area immediately,

get fresh air, and SEEK MEDICAL TREATMENT.

To prevent serious injuryor death from carbon monoxide:

NEVER runengine indoors.Even ifyou tryto

ventilateengine exhaustwithfansor open windows

and doors,carbon monoxidecan rapidlyreach

dangerous levels.

NEVER runengine in poorly-ventilated or partially

enclosed areas suchas barns, garages,

basements, carports,under dwellings,or in pits.

NEVER runengineoutdoorswhere engine exhaust

can bedrawnintoa buildingthroughopeningssuch

as windows and doors.

B. Avoid Gasoline Fires

Gasoline (fuel) vapors are highlyflammable

and can explode. Fuel vaporscan spread

and be ignitedby a spark or flame manyfeet

away from engine.To preventinjuryordeath

from fuel fires,follow these instructions:

• NEVER storeengine withfuel infuel

tank inside a building with potential

sources of ignition such as hot water and space

heaters, clothesdryers, electric motors,etc.

NEVER removefuel cap oradd fuel when engine is

running.

NEVER startoroperate the engine withfuel fill cap

removed.

• Allow engine to coolbefore refueling.

• DO NOT smoke whilerefueling tank.

Use onlyan approved red GASOLINE container to

storeand dispense fuel. Tecumsehrecommends

purchasinggasolineincontainerswitha capacityof

2.5 gallonsor less. Small containersare easier to

handle and help eliminatespillageduring refueling.

• DO NOT pour fuel from engine or siphonfuel by

mouth. To emptyfuel tank see "1.Draining Fuel"

instructions on page 14.

Adult Supervision of Operation, Refueling

and Maintenance

The manufacturerof the applicationmay provide

informationaboutwho isallowedto use this engine (see

equipment manufacturer's manual). Not everyone who is

allowed to use this engine is capable of safely and

responsibly operating, maintaining and/or fueling it.

Tecumseh recommends the following:

• An adult shouldfuel this engine. NEVER allow

childrento refuelthis engine.See "B. Filling Fuel

Tank"instructionson page 4.

• An adult shouldperformmaintenance on this

engine. See "VII. Maintenance"instructionson

page 11. Only allow childrento perform

maintenance if an adulthas determinedthey are

experienced and capable ofsuch operation.

• An adultshouldstart the engine. See "G Avoid

AccidentalStarts" instructionson page 2. Only allow

children to start the engine if an adult has

determined they are experienced and capable of

such operation.

To avoid unsupervisedoperationofthe engine, especially

by children,NEVER leave it unattendedwhen it isrunning.

D. Stay Away from Rotating Parts

NEVER operatethe engine with an unguardedengine

shaft.

The equipment manufacturer may attach

a sprocketand chain or pulley and belt to

the engine shaft. If these parts are not

properlyguarded, or ifyou are not sure

whetherthey are preperlyguarded, DO

NOT use yourengine; contactthe

equipmentmanufacturer. Hands, feet,

hair,jewelry, clothing,etc. can become

entangled inrotatingparts, leadingto

sedousinjuryor death. To avoid serious

injuryor death, be sure the flywheel

guard is in place.See Figure1,

on page 2.

181-807-14 Two-Cycle Engine • HorizontalA/ertical Crankshaft •Air-Cooled Page 1

E. Do Not Modify Engine

To avoid serious injury or death, DO NOT modify engine in

any way. Tampering with the governor setting can lead to a

runaway engine and cause it to operate at unsafe speeds.

NEVER tamper with factory setting of engine governor.

Use of thisengine on fun-carts, go-kartsor mini-bikes

could result in serious injury or death. Tecumseh

manufactures the Power Sport line of engines for use in

such applications. Consult your local Authorized

Tecumseh Servicing Dealer, call 1-800-558-5402, or go

to www.TecumsehPower.com for additional information.

F. Avoid Burns and Fire from Hot Surfaces

The mufflerand other engine parts become

extremely hotduring operationand remain

hotafter the engine has stopped.

To avoidsevere bums on contact,

NEVER operate the engine without

the mufflerguard inplace and avoid

hot areas of the engine.

To reduce the riskof fire keep all materialsthat can

burn, includinggrassand leaves, away from muffler

and rest of engine. DO NOT operate, idle or park

the engine application in long dry grass or other dry

ground cover.

G, Avoid Accidental Starts

To prevent accidental starting when working on equipment

always:

• Disconnectsparkplug wire and keep itaway from

spark plug. See Figures 2 and 3.

• Keep the disconnected spark plug wire

securelyaway from metal parts where arcing

couldoccur.

• Attach the sparkplug wire to the grounding

post, ifprovided.

• Disconnect batteryat negativeterminal first, if

engine isequipped with an electricstarter.

• Turn offall engine switches.

• Remove ignitionkey, ifprovided.

VIII. Transporting Your Engine

NEVER transport this engine inside

another vehicle or in any enclosed

space if there is any gasoline in the tank. Fuel vapor or

spilled fuel may ignite.

If there is fuel in the fuel tank, close

the fuel shut off valve, if equipped,

and transport the engine in an open vehicle, such as an

open trailer or open bed of a pickup truck.

If you do not have an open vehicle and have to transport

the engine in a closedvehicle, followthese stepsfor

emptyingthe fuel tank before transporting:

1. Empty fuel tank by usinga commemiallyavailable suc-

tiondevice designed for usewith gasoline.

DO NOT pour fuel from engine or

siphonfuel by mouth.

2. Drain fuel intoan approved red GASOLINE container,

being careful to avoid spilling.

3. Run the engine untilremaining fuel is consumed.

NEVER leave the engine

unattended when itis running and

NEVER runengine inencfosedareas.

IX. Storing Your Engine

A. Short TermlSeasonal Storage

I. Clean Engine

Before servicingthe engine remove the blower housing,tn

addition,remove grass clippings,dirt and debrisfrom the

followingareas:

• Coolingfins

Air intake screen

Levers

Linkage

Guards

Carburetor

Head

Removing debris willfacilitate adequate cooling,correct

engine speed and reduce the risk of fire.

II. Fuel Storage

NEVER storeengine withfuel in fuel

tank inside a building with potential

sources of ignition such as hot water and space heaters,

clothes dryers, electdc motors, etc. Failure to do so may

result in an explosion and result in death or serious injury.

NOTES

If engine fuel storedin the gas tank and/or an approved gas

container is to be unused without gasoline stabilizerfor

more than 15-30 days, prepare itfor shortterm/seasenal

storage. See 'YV Fuel Treatment" instructionson page 14.

If engine fuel is to be storedfor more than one season,

without gasoline stabilizer,itwill gradually deteriorate. Also,

if it is stored in the engine's gas tank without gasoline

stabilizer itis likely that your carburetor will have gum

deposits,a clogged fuel system and will voidyour warranty.

Prepare the fuel for extended storage. See "B. Extended

Storage" instructions on page 14.

If you operate the engine during all 4 seasons,it is not

necessary to lubricate the cylinder bore.

181-807-14 Two-Cycle Engine. Horizontal/Vertical Crankshaft • Air-Cooled Page 13

III. FueISystem B. Extended Storage

To avoidstale gas and carburetorproblems,treat the fuel

system inthe followingmethod below:

NOTES

Tecumseh recommends using ULTRA-FRESH TM or Fuel

Saver Plus Gasoline Stabilizer plus Fuel System Cleaner as

an acceptable method of minimizing formation of fuel gum

deposits during storage. This product is available from your

Authorized Tecumseh Servicing Deale_

Always follow mixratio found on stabilizer container. Failure

todo so may result in equipment damage.

It is not necessary to drain stabilized gas from carburetor.

IV. Fuel Treatment

1. Add fuel stabilizeraccordingto manufacturer's

instructions.

2. Run engine at least 10 minutes afteraddingstabilizer

toallow itto reach carburetor.

reii

NEVER storethe engine with fuel in

the fuel tank insidea building with

potentialsources ofignitionsuch as hot water and space

heaters, clothesdryers, electricmotors,etc.

NOTE

Instead of using a fuelpreservative/stabilizer, you can

empty the fuel tank as described under "1.Draining Fuel"

instructions. See "B. Extended Storage" instructions.

I. Draining Fuel

NOTES

Clean debris from engine before draining fuel from

carburetor See "1.Clean Engine" instructions on page 13.

If you have prepared your fuel for shortterm storage it is not

necessary to drain fuel that contains stabilizerfrom your

carburetor. See "A. Short Term/Seasonal Storage"

instructions on page 13.

X. Preventing Forest, Brush and Grass

Fires

Local, state and federal laws may require useof a spark

arresterto preventfires. For example, it isa violationof

California PublicResources Code (section4442) to use or

operate engine on anyforest-covered, brush-ceveredor

unimprovedgrass-cevered landunlessengine is equipped

witha spark attester. Spark attester mustbe maintainedin

effectiveworkingorder byowner and/oroperator.

To determine ifyour engine has a spark arrester, locatethe

muffleron yourengine. Forexample, the mufflerdischarge

willhave a spark arrestercover that reads "Tecumseh

Screen Type 36085".

If yourengine does not have a sparkarrester, you may

purchase one from yourAuthorized Tecumseh Servicing

Dealer• In some cases the mufflermay need to be replaced

toallow the spark arresterto be installed•
