C. Adult Supervision of Operation, Refueling and Maintenance
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. Not everyone who is allowed to use an engine is capable of safely and responsibly operating, maintaining and/or fueling it. Tecumseh 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

Todays fuels have a short shelf life and it is recommended you buy no more than a two week supply at a time. GASOLINE Tecumseh Power Company strongly recommends the use of fresh, clean, unleaded regular gasoline in all Tecumseh 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 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 15-30 days, prepare it for short term/seasonal storage. Tecumseh 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 Tecumseh 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
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 Tecumsehs 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.
Tecumseh 4-Cycle Lubrication Requirements
Tecumseh 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.
Tecumseh Recommended Oil Usage Straight Grade Tecumseh Part No. 730225A or SAE30W Multi Grade Tecumseh Part No. 730226A or SAE5W30 or SAE10W Synthetic Tecumseh Part No. 730263 or SAE0W30 -20 F 20 F 0F O O O -20 C -10 C -30 C

4-Cycle Troubleshooting

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 Tecumseh Servicing Dealer.

Preparation

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 fires and/or explosions, NEVER use flammable solvents (e.g., gasoline) to clean serviceable parts. Use a water-based, non-flammable solvent such as Tecumseh 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 flying debris.

Wear appropriate eye protection. Use only approved air blow nozzles.

Basic Gear Drive Troubleshooting
NOTE 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 avoid carbon monoxide poisoning, make sure engine is outdoors in a well-ventilated area. Some maintenance procedures can not be performed until the vehicle wheels are secured and off the ground. Failure to do so could result in death or serious injury to yourself and/or bystanders. DO NOT attempt any maintenance procedures with the engine running. Doing so could result in death or serious injury to yourself and/or bystanders. Use care when performing inspection of the drive belt assembly including all vehicle linkage. Failure to do so could result in death or serious injury to yourself and/or bystanders.
Hard Shifting Transaxles and Drive Belts
Often hard shifting is blamed on an internal problem in the transaxle. To determine if the problem is transaxle or equipment related make these simple checks. 1. Turn the unit off so that all power is removed to the transaxle. 2. With the unit off, move the shift lever through the shift gate. Movement of the lever should have only slight resistance. The shifting effort should be equal when the engine is off and when running. If the unit is difficult to shift the problem would be internal and the transaxle would need to be removed and repaired. 3. If the unit shifts with ease, check the following areas that would be equipment related. Check to see if the belt is releasing from the pulley on the engine and transmission / transaxle, it may require that the belt guides be repositioned. The distance required from the pulley to the guide is typically 1/16" to 3/16" (1.6 mm - 4.8 mm), always check the O.E.M. specs.

1/16" to 3/16" (1.6 mm - 4.8 mm)
THIS DIMENSION VARIES FROM EACH MANUFACTURER
For proper declutching to occur, it is very important that the engine belt guide be set at a predetermined clearance when engaged (set by the manufacturer) and away from the belt with the belt engaged.
With clutch disengaged, it is very important that the belt blossoms away from the engine pulley. Belt must stop turning before transaxle shifting can occur.
Improper belt or belt guide clearance will not allow the belt to disengage, causing internal transmission damage. 20
Basic Gear Drive Troubleshooting - continued
4. Check to see if the pulley is damaged and may not be releasing the belt. 5. Confirm the correct length and type of belt, as recommended by the manufacturer, is installed. 6. Check the brake/clutch pedal to make sure that when the pedal is depressed that the idler pulley is releasing the belt tension before it applies the brake. If this does not happen the unit will still be under a load and be impossible to shift. 7. The final area to check would be for damaged or binding shift linkage. Hard shifting with the engine off could be caused by: 1. Shift linkage out of adjustment. 2. Corrosion in the transaxle or transmission. 3. Damaged shift keys, gears, or shifter brake shaft. 4. Belt guides missing or improperly adjusted (see equipment manufacturer specs). Unit seems to slip: 1. Check for proper belt adjustment (consult O.E.M. operator's manual). 2. Check for proper clutch/brake adjustment (consult O.E.M. operator's manual). 3. Check pulley condition and wheels for sheared or damaged keys. 4. Check drive belt condition, if glazed or worn, replace it. 5. Possible internal transmission damage. We suggest you contact a local Tecumseh Servicing Dealer.
