•Keep this manual handy at all times for future reference.
•Read it carefully and familiarize yourself with operating, maintenance, components and safety instructions.
CAUTION
CAUTION
NOTE
Refers to important information and is placed in italic type.
NOTE
Engines which are certified to comply with California and U.S. EPA emission regulations for SORE (Small Off Road Equipment), are certified to operate on regular unleaded gasoline, and may include the following emission control systems: (EM) Engine Modification and (TWC) Three-way Catalyst (if so equipped).
For engine adjustments, repairs or warranty service NOT covered in this manual, contact your nearest Authorized TecumsehPower Servicing Dealer. Find them on our website at www.TecumsehPower.com or call TecumsehPower Company at 1-800-558-5402 for additional information.

! WARNING
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 TecumsehPower Servicing Dealer, call 1-800-558-5402, or go to www.TecumsehPower.com for additional information.
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.
•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
•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 fill 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.
181-1032-14
•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. TecumsehPower Company 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 14.
C.Adult Supervision of Operation, Refueling and Maintenance
The manufacturer of the equipment 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. TecumsehPower Company recommends the following:
•An adult should fuel this engine. NEVER allow children to refuel this engine. See "C. Filling Fuel Tank" instructions on page 5.
•An adult should perform maintenance on this engine. See "VII. Maintenance" instructions on page 10. 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. 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. Remove ignition key, if equipped.
D.Stay Away from Rotating Parts
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 Figures 1 and 2 on page 2.
Page 1
! WARNING
Use of this engine on fun-carts, go-karts, or mini-bikes can result in serious injury or death. TecumsehPower Company manufactures the Power Sport line of engines for use in such applications. Consult your local Authorized TecumsehPower Servicing Dealer, call 1-800-558-5402, or visit www.TecumsehPower.com for additional information.
F.Avoid Burns and Fire from Hot Surfaces
•To avoid severe burns on contact, STAY AWAY from hot areas of engine. DO NOT operate the engine without the muffler guard in place, if equipped.
•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 engine powered equipment in long dry grass or other dry ground cover.
G.Avoid Accidental Starts
•Carefully disconnect spark plug wire and keep it away from spark plug. See Figures 3 and 4.
•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 a DC electric starter.
•Turn all engine switches to “OFF” position.
•Remove ignition key, if provided.
H.Use Hearing Protection

A. Oil
NOTES
The oil sump capacity is 21 ounces or 1-1/4 U.S. Pints (.62 liters).
Be sure original container is marked A.P.I. Service “SL/SJ”.
Using multigrade oil above 32°F (0°C) will increase oil consumption. SAE 10W40 is NOT recommended.
Special-formulated oils are available at your Authorized TecumsehPower Servicing Dealer.
•DO NOT use leaded fuel.
•Fuel must be fresh and clean. NEVER use fuel left over from last season or stored for long periods.
•NEVER mix oil with fuel.
•DO NOT use fuel containing Methanol (Wood Alcohol).
|
The use of alternative fuels such as E85 |
|
CAUTION |
||
or E20 are NOT recommended for use in |
||
|
||
|
||
TecumsehPower engines. Alternative fuels with high |
alcohol content can cause hard starting, poor engine performance, and may cause internal engine damage.
NOTE
Damage and/or performance problems that occur from use of fuels other than those listed in the Operator’s Manuals will not be considered warranty.
•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. See Figure 7.
•Insure 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 and cause 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.
Contact your Authorized TecumsehPower Servicing Dealer for TecumsehPower Oil.
