• NEVER fill fuel tank indoors. Fill fuel tank outdoors  
in a well-ventilated area.  
I. General Safety Precautions  
• DO NOT smoke while refueling tank.  
! WARNING  
• Use only an approved red GASOLINE container to  
store and dispense fuel. Tecumseh recommends  
purchasing gasoline in containers with a capacity of  
2.5 gallons or less. Small containers are easier to  
handle and help eliminate spillage during refueling.  
Read equipment manufacturer’s manual and this  
material thoroughly before using this engine. Failure to  
do so can result in serious injury or death. Call Tecumseh  
Power Company at 1-800-558-5402 or visit  
• DO NOT pour fuel from engine or siphon fuel by  
mouth. To empty fuel tank see "I. Draining Fuel"  
instructions on page 16.  
A. Avoid Carbon Monoxide Poisoning  
All engine exhaust contains  
carbon monoxide, a deadly  
gas. Breathing carbon  
C. Adult Supervision of Operation, Refueling  
and Maintenance  
monoxide can cause  
headaches, dizziness,  
The manufacturer of the application may provide  
information about who is allowed to 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:  
drowsiness, nausea, confusion  
and eventually death.  
Carbon monoxide is a colorless, odorless, tasteless gas  
which may be present even if you do not see or smell any  
engine exhaust. Deadly levels of carbon monoxide can  
collect rapidly and you can quickly be overcome 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 symptoms of  
carbon monoxide poisoning, leave the area immediately,  
get fresh air, and SEEK MEDICAL TREATMENT.  
• An adult should fuel this engine. NEVER allow  
children to refuel this engine. See "G. Filling Fuel  
Tank" instructions on page 6.  
• An adult should perform maintenance on this  
engine. See "VII. Maintenance" instructions on  
page 12. Only allow children to perform  
maintenance if an adult has determined they are  
experienced and capable of such operation.  
To prevent serious injury or death from carbon monoxide:  
• NEVER run engine indoors. Even if you try to  
ventilate engine exhaust with fans or open windows  
and doors, carbon monoxide can rapidly reach  
dangerous levels.  
• An adult should start the engine. See "G. Avoid  
Accidental Starts" instructions on page 2. Only allow  
children to start the engine if an adult has  
determined they are experienced and capable of  
such operation.  
• NEVER run engine in poorly-ventilated or partially  
enclosed areas such as barns, garages,  
basements, carports, under dwellings, or in pits.  
To avoid unsupervised operation of the engine, especially  
by children, NEVER leave it unattended when it is running.  
• NEVER run engine outdoors where engine exhaust  
can be drawn into a building through openings such  
as windows and doors.  
D. Stay Away from Rotating Parts  
NEVER operate the engine with an unguarded engine  
shaft. See Figure 1.  
B. Avoid Gasoline Fires  
The equipment manufacturer may attach  
a sprocket and chain or pulley and belt to  
the engine shaft. If these parts are not  
properly guarded, or if you are not sure  
whether they are properly guarded, DO  
NOT use your engine; contact the  
equipment manufacturer. Hands, feet,  
hair, jewelry, clothing, etc. can become  
entangled in rotating parts, leading to  
serious injury or death. To avoid serious  
injury or death, be sure the flywheel  
guard is in place. See Figure 1. See  
Figure 2.  
Gasoline (fuel) vapors are highly flammable  
and can explode. Fuel vapors can spread  
and be ignited by a spark or flame many feet  
away from engine. To prevent injury or death  
from fuel fires, follow these instructions:  
• NEVER store engine with fuel in fuel  
tank inside a building with potential  
sources of ignition such as hot water and space  
heaters, clothes dryers, electric motors, etc.  
• NEVER remove fuel cap or add fuel when engine is  
running.  
• NEVER start or operate the engine with fuel fill cap  
removed.  
• Allow engine to cool before refueling.

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.  
! WARNING  
Use of this engine on fun-carts, go-karts or 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

to www.TecumsehPower.com for additional information.  
Figure 1. DO NOT Use Without Engine Shaft Guard  
F. Avoid Burns and Fire from Hot Surfaces  
The muffler and other engine parts become extremely hot  
during operation and remain hot after the engine has  
stopped.  
To avoid severe burns on contact,  
NEVER operate the engine  
without the muffler guard in place,  
see Figure 2 and avoid hot areas  
of the engine.

sources of ignition such as hot water and space heaters,  
clothes dryers, electric motors, etc. Failure to do so may  
result in an explosion and result in death or serious injury.  
NEVER run engine in enclosed areas.  
NOTES  
If engine fuel stored in the gas tank and/or an approved gas  
container is to be unused without gasoline stabilizer for  
more than 15-30 days, prepare it for short term/seasonal  
storage. See "III. Fuel Treatment" instructions on page 16.  
If engine fuel is to be stored for more than one season,  
without gasoline stabilizer, it will gradually deteriorate. Also,  
if it is stored in the engine’s gas tank without gasoline  
stabilizer it is likely that your carburetor will have gum  
deposits, a clogged fuel system and will void your warranty.  
Prepare the fuel for extended storage. See "B. Extended  
Storage" instructions on page 16,  
If you operate the engine during all 4 seasons, it is not  
necessary to lubricate the cylinder bore.

Clean debris from engine before draining fuel from  
carburetor. See "I. Clean Engine" instructions on page 15,  
Tecumseh recommends using ULTRA-FRESH™  
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 Dealer.  
If you have prepared your fuel for short term storage it is not  
necessary to drain fuel that contains stabilizer from your  
carburetor. See "A. Short Term/Seasonal Storage"  
instructions on page 15.  
Always follow mix ratio found on stabilizer container. Failure  
to do so may result in equipment damage.

5. Grasp starter cord handle and pull out slowly using a  
full arm stroke. Repeat once. (This will distribute oil  
throughout the cylinder to prevent corrosion during  
storage.) Proceed to Step 8.  
X. Preventing Forest, Brush and Grass  
Fires  
Local, state and federal laws may require use of a spark  
arrester to prevent fires. For example, it is a violation of  
California Public Resources Code (section 4442) to use or  
operate engine on any forest-covered, brush-covered or  
unimproved grass-covered land unless engine is equipped  
with a spark arrester. Spark arrester must be maintained in  
effective working order by owner and/or operator.  
6. Push starter button or turn ignition switch key (see  
equipment manufacturer’s instructions) to cycle the  
engine for one to two seconds.  
7. Turn ignition switch key to “OFF” position. Repeat Step  
6 and Step 7. (This will distribute oil throughout the cyl-  
inder to prevent corrosion during storage.)  
8. Remove rag covering spark plug hole and install spark  
plug.  
To determine if your engine has a spark arrester, locate the  
muffler on your engine. For example, the muffler discharge  
will have a spark arrester cover that reads “Tecumseh  
Screen Type 36085”.  
9. Carefully disconnect spark plug wire from grounding  
post, if provided. See Figure 36.  
If your engine does not have a spark arrester, you may  
purchase one from your Authorized Tecumseh Servicing  
Dealer. In some cases the muffler may need to be replaced  
to allow the spark arrester to be installed.  
NOTE  
Connect spark plug wire before attempting to start engine  
once engine is out of storage.

other original engine components or approved  
modifications proximately caused by a failure under  
warranty of an emission-related part covered by the ECS

THIS EXPRESS WARRANTY IS SUPPLEMENTED BY THE TECUMSEH CALIFORNIA EMISSION CONTROL WARRANTY STATEMENT, if any.  
THIS EXPRESS WARRANTY IS IN LIEU OF ALL OTHER EXPRESS WARRANTIES. Neither Tecumseh nor any of its affiliates makes any warranties, representations, or  
promises, written or oral, as to the quality of the engine or any of its parts, other than as set forth herein. ANY IMPLIED WARRANTY OF MARKETABILITY,  
MERCHANTABILITY, OR FITNESS FOR A PARTICULAR PURPOSE, TO THE EXTENT THAT EITHER MAY APPLY TO ANY TECUMSEH ENGINE OR PART(S)  
THEREOF, SHALL BE LIMITED IN DURATION TO THE PERIODS OF THE EXPRESS WARRANTIES SHOWN IN THE WARRANTY PERIOD CHART ABOVE AND TO  
THE EXTENT PERMITTED BY LAW ANY AND ALL IMPLIED WARRANTIES ARE EXCLUDED. IN NO EVENT WILL TECUMSEH BE LIABLE FOR ANY INDIRECT,  
INCIDENTAL, CONSEQUENTIAL OR SPECIAL DAMAGES AND/OR EXPENSES, INCLUDING, BUT NOT LIMITED TO, ANY LOSS OF TIME, INCONVENIENCE,  
LOSS OF UNIT USE OR ANY COST OR EXPENSE OF SUBSTITUTE UNITS DURING PERIODS OF MALFUNCTION OR NON-USE. Some states do not allow  
limitations on how long an implied warranty lasts or the exclusion or limitation of incidental or consequential damages, so the above limitation(s) or exclusion(s) may not  
apply to you. This Limited Warranty gives you specific legal rights and you may also have other legal rights which vary from state-to-state.  
Tecumseh neither assumes nor authorizes any other person, natural or corporate, to assume for Tecumseh any other obligations or liabilities in connection with or with  
respect to any Tecumseh product or parts. The seller or dealer of a Tecumseh Product or part has no authority, whatsoever, to make any representations or promises on  
behalf of Tecumseh or to modify the terms or limitations of Tecumseh’s warranty in any way.
