Safety Definitions	2
Statements in this manual preceded by the following words and graphics are of special significance:	2
Or	2
WARNING indicates a potentially hazardous situation which if NOT avoided, could result in death or serious injury.	2
Indicates a potentially hazardous situation which, if NOT avoided, may result in minor or moderate injury.	2
Indicates a potential situation which, if NOT avoided, could result in equipment or property damage.	2

Notice Regarding Emissions	2
TecumsehPower Contact Information	2
I. General Safety Precautions	3
A. Avoid Carbon Monoxide Poisoning	3
All engine exhaust contains carbon monoxide, a deadly gas. Breathing carbon monoxide can cause headaches, dizziness, drowsiness, nausea, confusion and eventually death.	3
Carbon monoxide is a colorless, odorless, tasteless gas which may be present even if you DO NOT see or smell any engine exhaust....	3
To prevent serious injury or death from carbon monoxide:	3
B. Avoid Gasoline Fires	3
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:	3
C. Adult Supervision of Operation, Refueling and Maintenance	3
The manufacturer of the equipment may provide information about who is allowed to use this engine (see equipment manufacturer’s ...	3
D. Stay Away from Rotating Parts	3
NEVER operate the engine with an unguarded engine shaft or flywheel. See Figure 1 on page 2.	3
The equipment manufacturer may attach a sprocket and chain or pulley and belt to the engine shaft. If these parts are NOT proper...	3
E. DO NOT Modify Engine	4
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.	4
F. Avoid Burns and Fire from Hot Surfaces	4
The muffler and other engine parts become extremely hot during operation and remain hot after the engine has stopped.	4
G. Avoid Accidental Starts	4
To prevent accidental starting when working on equipment always:	4
H. Use Hearing Protection	4
Engine noise may cause hearing damage. Always wear hearing protection when operating an engine.	4

II. How to Get Service	5
A. Engine Identification Decal	5
A sample engine identification decal is located in the next column and indicates the engine’s model number, specification and date of manufacture (DOM). See Figure 4.	5
The engine identification decal also includes engine life specifications for the emissions-related useful life period of your engine. This period relates to the emission compliance life as certified by EPA and/or CARB.	5
B. Technician’s Handbook	5
If you have a general understanding of internal combustion engines and wish to repair and service your engine and/or engine emis...	5
TecumsehPower Company manufactures and is responsible only for the engine used on this power equipment. If repair or service is needed for anything other than the engine, contact the service source recommended by the equipment manufacturer.	5
Figure 4. Engine Identification Decal	5
Figure 5. Technician’s Handbook	5
III. Oil and Fuel Specifications	6
A. Oil	6
To operate engine you need to use a clean, high quality, detergent oil. For recommended engine oil, see Table 1. In addition, you need to be sure the oil sump contains the correct amount of oil to operate properly.	6
Special-formulated oils are available at your Authorized TecumsehPower Servicing Dealer.	6
B. Fuel	6
Use unleaded regular, unleaded premium or reformulated automotive fuel only. You may use gasoline containing the components identified in Table 2.	6
The use of alternative fuels such as E85 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.	6
IV. Before Starting Your Engine	6
A. Checking Oil Level	6
To avoid engine damage, it is important to:	6

VIII. Transporting Your Engine	23
NEVER transport this engine inside another vehicle or in any enclosed space if there is any gasoline in the tank. Fuel vapor or spilled fuel may ignite leading to serious injury or death.	23
If there is fuel in the fuel tank, close the fuel shut-off valve, if equipped, and transport the engine upright in an open vehicle, such as an open trailer or open bed of a pickup truck.	23
If you DO NOT have an open vehicle and have to transport the engine upright in a closed vehicle, follow these steps for emptying the fuel tank before transporting:	23
1. Empty fuel tank by using a commercially available suction device designed for use with gasoline.	23
To avoid serious injury or death, DO NOT pour fuel from engine or siphon fuel by mouth.	23
2. Drain fuel into an approved red GASOLINE container, being careful to avoid spilling.	23
3. Run the engine until remaining fuel is consumed.	23
NEVER leave the engine unattended when it is running and NEVER run engine in enclosed areas to avoid death or serious injury.	23
IX. Storing Your Engine	24
A. Short-Term/Seasonal Storage	24
I. Clean Engine	24
Before servicing the engine remove the air cleaner cover and/or blower housing. Remove grass clippings, dirt and debris from the following areas:	24
Removing debris will insure adequate cooling, correct engine speed and reduce the risk of fire.	24
II. Fuel Storage	24
NEVER store engine with fuel in the fuel tank inside a building with potential sources of ignition such as hot water or space heaters, clothes dryers, electric motors, etc. Doing so may lead to an explosion resulting in death or serious injury.	24
III. Fuel System	24
To avoid stale gas and carburetor problems, treat the fuel system in the following method below:	24
It is NOT necessary to empty stabilized gas from fuel tank.	24
IV. Fuel Treatment	24
1. Add fuel stabilizer according to manufacturer’s instructions.	24
2. Run engine at least 10 minutes after adding stabilizer to allow it to reach carburetor.	24
NEVER store engine with fuel in the fuel tank inside a building with potential sources of ignition such as hot water or space heaters, clothes dryers, electric motors, etc. Doing so may lead to an explosion resulting in death or serious injury.	24
B. Extended Storage	25
I. Draining Fuel	25
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.	25
2. Run the engine while waiting until the remaining fuel is consumed.	25
NEVER leave the engine unattended when it is running and NEVER run engine in enclosed areas to avoid death or serious injury.	25
3. Begin servicing the cylinder bore. See \	25
II. Oil Cylinder Bore	25
When lubricating cylinder bore, fuel may spray from spark plug hole. To prevent serious injury from fuel fires, follow these instructions:	25
1. Carefully disconnect spark plug wire and keep it away from spark plug. See Figures 53 and 54.	25
2. Remove spark plug.	25
3. Squirt 1oz. (30 ml) of clean engine oil into spark plug hole.	25
4. Cover spark plug hole with rag to prevent fuel from spraying from spark plug hole when engine is started.	25

5. Grasp starter cord handle:	25
a. Pull out slowly using a full arm stroke.	25
b. Repeat once. (This will distribute oil throughout the cylinder to prevent corrosion during storage.)	25
c. Proceed to Step 7.	25
6. Push starter button or turn ignition switch key to “START” position. Immediately release starter button or turn ignition switch key to “OFF” position. (This will distribute oil throughout the cylinder to prevent corrosion during storage.)	25
7. Remove rag covering spark plug hole.	25
8. Install spark plug.	25
9. Carefully disconnect spark plug wire from grounding post, if provided.	25
10. Connect spark plug wire to spark plug before attempting to start engine.	25
III. Oil	25
Change oil if NOT changed within the last 3 months. See \	25
IV. Battery	25
See equipment manufacturer’s instructions for proper battery storage, if machine is equipped with a battery.	25
X. Preventing Forest, Brush and Grass Fires	26
Local, state and federal laws may require use of a spark arrester to prevent fires. For example, it is a violation of California...	26
To determine if your engine has a spark arrester, locate the muffler on your engine. For example, the muffler discharge will have a spark arrester cover that reads “Screen Type 36085”.	26
If your engine does NOT have a spark arrester, you may purchase one from your Authorized TecumsehPower Servicing Dealer. In some cases the muffler may need to be replaced to allow the spark arrester to be installed.	26
XI. Maintenance Intervals	26
ALWAYS promptly follow maintenance intervals listed in this manual. See Table 5.	26
