    I. General Safety Precautions
    !
    WARNING
    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 
    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.
    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 the fuel fill 
    cap removed.
    • Allow engine to cool before refueling.• NEVER fill 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 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.
    • DO NOT pour fuel from engine or siphon fuel by 
    mouth. To empty the fuel tank see I. Draining Fuel 
    instructions on page 18.
    C. Adult Supervision of Operation, Refueling 
    and Maintenance
    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:
    • An adult should fuel this engine. NEVER allow 
    children to refuel this engine. See C. Filling Fuel 
    Tank instructions on page 6.
    • An adult should perform maintenance on this 
    engine. See VII. Maintenance instructions on 
    page 13. Only allow children to perform mainte-
    nance if an adult has determined they are exper-
    enced and capable of such operation.
    • 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.
    • 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 the engine with an unguarded flywheel. 
    See Figure 1 on page 2.
    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 on page 2. Read equipment manufacturer’s manual and this
    material thoroughly before using this engine. Failure to
    do so can result in serious injury or death. Consult your
    local Authorized Tecumseh Servicing Dealer, call 1-800-
    558-5402, or go to www.TecumsehPower.com for
    additional information.

    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
    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, and avoid 
    hot areas of the engine. 
    See Figure 1.
    • To reduce the risk of fire keep all materials that can 
    burn, including grass and 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:
    • Carefully disconnect spark plug wire and keep it 
    away from spark plug. See Figures 2 and 3.
    • Keep the disconnected spark plug wire 
    securely away from metal parts where arcing 
    could occur. 
    • Carefully attach the spark plug wire to the 
    grounding post, if provided. 
    • Disconnect battery at negative terminal first, if 
    engine is equipped with an electric starter.
    • Turn off all engine switches.
    • Remove ignition key, if provided.
    H. Use Hearing Protection
    Engine noise may cause hearing damage. Always wear 
    hearing protection when operating an engine.Use of this engine on fun-carts, go-karts, or mini-bikes
    can result in serious injury or death. Tecumseh

    IV. Before Starting Your Engine
    A. Checking Oil Level
    To avoid engine damage, it is important to:
    • Check oil level before each use and every 5 
    operating hours when engine is warm. Check oil 
    level more frequently during engine break-in.
    • Keep oil level between “FULL” and “ADD” marks on 
    dipstick or to point of overflow on engines without 
    dipstick. See Figure 6.
    • Be sure oil fill cap/plug is tightened securely.
     NOTES
    DO NOT overfill oil filler. Doing so may result in oil carry-
    over to the air cleaner and equipment malfunction or 
    damage.
    DO NOT allow oil level to fall below the “ADD” mark on 
    dipstick. Doing so may result in equipment malfunction or 
    damage.

    C. Filling Fuel Tank
    An adult should fuel this engine. 
    NEVER allow children to refuel this 
    engine. 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:
    1. Stop engine and allow it to cool before refueling.
    2. Be sure engine is outdoors and in a well-ventilated 
    area.
    3. Clean area around fuel fill cap and remove fuel fill cap. 
    See Figure 7 on page 5. Afterward, continue reading 
    instructions below.
    4. Using an approved red GASOLINE container, add fuel 
    slowly, being careful to avoid spilling. DO NOT overfill 
    fuel tank. Leave space in the tank to allow fuel to 
    expand without overflowing.
    5. Replace anti-splash fuel fill cap securely and wipe up 
    spilled fuel before starting engine. If fuel is spilled DO 
    NOT start engine. Move machine away from area of 
    spillage. Avoid creating any source of ignition until fuel 
    vapors are gone.
     NOTE
    Replace a damaged or missing fuel fill cap only with a 
    genuine Tecumseh replacement anti-splash fuel fill cap. 
    Failure to do so may VOID YOUR WARRANTY. See Figure 
    8.

    V. Starting Your Engine
    An adult should start the engine. 
    Only allow children to start engine if 
    an adult has determined they are experienced and capable 
    of such operation.
    If you are unable to start this engine 
    after following instructions in this 
    manual, contact your Authorized Tecumseh Servicing 
    Dealer. To avoid serious burn injuries or damage to your 
    engine, DO NOT attempt to start or troubleshoot this 
    engine in any other way. For example:
    • DO NOT use starting fluid.
    • DO NOT spray flammable vapors into carburetor or 
    onto air cleaner.
    • DO NOT put flammable liquids into carburetor or 
    onto air cleaner.
    • DO NOT operate engine or pull on starter rope with 
    spark plug removed. Fuel can spray from spark plug 
    hole and ignite. 
    This section contains starting instructions for several 
    different types of engines. In order to locate the instructions 
    that apply to your engine, first determine what type of starter 
    you have. If you have an electric starter see A. Engine 
    Sections with Electric Starters instructions below. If you 
    have a manual recoil starter, see B. Engine Sections with 
    Recoil Starters instructions on page 10.
    A. Engine Sections with Electric Starters
    Only one of the following three sections will apply to your 
    engine. See Table 3.
