General Safety Precautions
A. Avoid Carbon Monoxide Poisoning
All engine exhaust contains carbon monoxide, a deadly gas. Breathing carbon monoxide can cause headaches, dizziness, 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
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.
•NEVER run engine in
•NEVER run engine outdoors where engine exhaust can be drawn into a building through openings such as windows and doors.
B.Avoid Gasoline Fires
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.
•NEVER fill fuel tank indoors. Fill fuel tank outdoors in a
•DO NOT smoke while refueling tank.
•Use only an approved red GASOLINE container
to store and dispense fuel. TecumsehPower 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.
•DO NOT pour fuel from engine or siphon fuel by mouth.
C.AdultSupervisionofOperation,Refueling and Maintenance
Not everyone who is allowed to use an engine is capable of safely and responsibly operating, maintaining and/or fueling it. TecumsehPower recommends the following:
•An adult should fuel the engine. NEVER allow children to refuel an engine.
•An adult should perform maintenance on an engine. Only allow children to perform maintenance if an adult has determined they are experienced and capable of such operation.
•An adult should start the engine. Only allow children to start the engine if an adult has determined they are experienced and capable of such operation.
To avoid unsupervised operation of the engine, especially by children, NEVER leave it unattended when it is running.
D. Stay Away from Rotating Parts
NEVER operate an engine with an unguarded engine shaft.
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.

Fuel Recommendations
Today’s fuels have a short shelf life and it is recommended you buy no more than a two week supply at a time.
GASOLINE
TecumsehPower strongly recommends the use of fresh, clean, unleaded regular gasoline in all TecumsehPower engines. Unleaded gasoline burns cleaner, extends engine life, and promotes good starting by reducing the
Reformulated gasoline that is now required in several areas of the United States is also acceptable.
NEVER USE gasoline, fuel conditioners, additives or stabilizers containing methanol, gasohol containing more than 10% ethanol, unleaded regular gasoline containing more than 15% MTBE (Methyl Tertiary Butyl Ether), 15% ETBE (Ethyl Tertiary Butyl Ether) or 10% ethanol, gasoline additives, or white gas because engine/fuel system damage could result.
SPECIALTY FUELS
Fuels being marketed for use on small engines can have a significant effect on starting and engine performance. Prior to using any specialty fuel, the Reid Vapor Pressure (RVP) must be determined. Fuels with a rating of less than 50kPa (7psi) should not be used in summer, and fuel with a rating of 85kPa (12psi) should not be used during winter.
SHORT TERM STORAGE
WARNING NEVER store the engine with fuel in the fuel tank inside a building with potential sources of ignition such as hot water and space heaters, clothes dryers, electric motors, etc.
If engine fuel stored in the gas tank and/or an approved gas container is to be unused without gasoline stabilizer for more than
TecumsehPower recommends using
Always follow mix ratio found on stabilizer container. Failure to do so may result in equipment damage.
It is not necessary to drain stabilized gas from carburetor.
FUEL TREATMENT
1.Add fuel stabilizer according to manufacturer’s instructions.
2.Run engine at least 10 minutes after adding stabilizer to allow it to reach carburetor.
3.Instead of using a fuel preservative/stabilizer, you can empty the fuel tank as described under "Extended Storage”.
7
Fuel Recommendations - continued
EXTENDED STORAGE
NOTES
Clean debris from engine before draining fuel from carburetor. If you have prepared your fuel for short term storage it is not necessary to drain fuel that contains stabilizer from your carburetor.
To avoid severe injury or death, DO NOT pour fuel from engine or siphon fuel by mouth.
1.To prevent serious injury from fuel fires, empty fuel tank by running engine until it stops from lack of fuel. DO NOT attempt to pour fuel from engine.
2.Run the engine while waiting until the remaining fuel is consumed.
NEVER leave the engine unattended when it is running and NEVER run engine in enclosed areas.
FUEL ADDITIVES
Only fuel additives such as TecumsehPower’s fuel stabilizer Part No. 730245A or liquid varieties can be used when mixed properly. For winter applications, Isopropyl alcohol fuel dryers may be used in the fuel system but must be mixed at the proper ratio recommended by the manufacturer. NEVER USE METHANOL
BASED FUEL DRYERS.
8
TECUMSEHPOWER
TecumsehPower recommends the use of a high quality, brand name oil with a minimum classification of SL/SJ. Very few air cooled engines have any type of oil filtration system, making regular oil changes critical to remove
impurities from the engine and maximize engine life.
Consult the operator's or repair manual for the oil change interval and viscosity based on equipment operating temperature.
