WARNING

WARNING indicates a potentially hazardous situation which if not avoided, could result in death or serious injury. NOTE Refers to important information and is placed in italic type. It is recommended that you take special notice of all items discussed on the next two pages and wear the appropriate safety equipment. Before operating an engine it is your responsibility to read the Operators Manual. Follow these basic rules for your personal safety: Keep this manual handy at all times for future reference. Read it carefully and familiarize yourself with operating, maintenance, components and safety instructions.
Notice Regarding Emissions
Engines which are certied to comply with California and U.S. EPA emission regulations for SORE (Small Off Road Equipment), are certied to operate on regular unleaded gasoline, and may include the following emission control systems: (EM) Engine Modication and (TWC) ThreeWay Catalyst (if so equipped).
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.
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. Adult Supervision of Operation, 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.

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. 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 poorly-ventilated or partially enclosed areas such as barns, garages, basements, carports, under dwellings, or in pits. 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 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 ywheel guard is in place.

B. Avoid Gasoline Fires

Gasoline (fuel) vapors are highly ammable and can explode. Fuel vapors can spread and be ignited by a spark or ame many feet away from engine. To prevent injury or death from fuel res, 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 ll cap removed. Allow engine to cool before refueling. NEVER ll fuel tank indoors. Fill fuel tank outdoors in a well-ventilated area. DO NOT smoke while refueling tank. Use only an approved red GASOLINE container

Todays 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 build-up of combustion chamber deposits. Leaded gasoline, gasohol containing no more than 10% ethanol, premium gasoline, or unleaded gasoline containing no more than 15% MTBE (Methyl Tertiary Butyl Ether), 15% ETBE (Ethyl Tertiary Butyl Ether) or 10% ethanol, can be used if unleaded regular gasoline is not available. 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 signicant 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

Fuel Recommendations

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 15-30 days, prepare it for short term/seasonal storage. TecumsehPower recommends using ULTRA-FRESH 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 TecumsehPower Servicing Dealer. 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 manufacturers 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.

Fuel Recommendations - continued
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 res, 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 TecumsehPowers 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. EXTENDED STORAGE
TECUMSEHPOWER 4-CYCLE LUBRICATION
TecumsehPower recommends the use of a high quality, brand name oil with a minimum classication of SL/SJ. Very few air cooled engines have any type of oil ltration 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.

Four Cycle Troubleshooting

Preparation

The following is provided as a basic troubleshooting guide. Its use requires a complete review of all conditions and symptoms. Always examine the exterior for clues: leaks, excessive dirt, or obvious damage. Some repairs will require the assistance of a TecumsehPower Servicing Dealer. Before troubleshooting any system problem, see original equipment manufacturers (O.E.M.) instructions. Make your troubleshooting easier by preparing as follows: Work in a clean, well-lighted place. Keep proper tools and materials nearby. Keep an adequate supply of clean petroleum-based solvent. To reduce the risk of serious injury or death from res and/or explosions, NEVER use ammable solvents (e.g., gasoline) to clean serviceable parts. Use a water-based, non-ammable solvent such as TecumsehPower Degreaser Cleaner. CAUTION NEVER use compressed air to clean debris from yourself or your clothing. When using compressed air to clean or dry serviceable parts: Air pressure must not exceed 30psi (206kPa). Shield yourself and bystanders from ying debris.
Wear appropriate eye protection. Use only approved air blow nozzles.
