Most accidents with engines can be prevented ifyou follow all instructions in this manual and on the engine. Some of the most common hazards are discussed below, along with the best way to protect yourself and others. The muffler becomes very hot during operation and remains hot for a while after stopping the engine. Be careful not to touch the muffler while it is hot. Let the engine cool before storing it indoors.ՕTo prevent fire hazards and to provide adequateventilation for stationary equipment applications, keep the engine at least 3 feet (1 meter) away from building walls and other equipment...

The fuel valve opens and closes the passagebetween the fuel tank and the carburetor. The fuel valve lever must be in the ON position for the engine to run. When the engine is not in use, leave the fuel valve lever in the OFF position to prevent carburetor flooding and to reduce the possibility of fuel leakage. The choke lever opens and closes the choke valvein the carburetor. The CLOSE position enriches the fuel mixture for starting a cold engine. The OPEN position provides the correct fuel mixture for opera- tion after starting and for restarting a warm engine.Some engine applications use a...

For your safety, and to maximize the service life ofyour equipment, it is very important to take a few moments before you operate the engine to check its condition. Be sure to take care of any problem you find, or have your servicing dealer correct it, prior to operating the engine. Check the engine oil level. Running the engine with a low oil level can cause engine damage. The Low Oil Sensor (applicable engine types) will auto- matically stop the engine before the oil level falls below safe limits. However, to avoid the inconven- ience of an unexpected shutdown, always check the engine oil level...

Before operating the engine for the first time,please review the IMPORTANT SAFETY INFORMATION and the section titled BEFOREOPERATION. Carbon monoxide gas is toxic. Breathing it cancause unconsciousness and even death.Avoid any areas or actions that expose you tocarbon monoxide. Review the instructions provided with the equip-ment powered by this engine for any safety precau- tions that should be observed in conjunction with engine startup, shutdown, or operation. > 1. Move the fuel valve lever to the ON position. 2. To start a cold engine, move the choke lever tothe CLOSE position. To restart...

Position the throttle lever for the desired enginespeed. Some engine applications use a remotely- mounted throttle control rather than the engine- mounted throttle lever shown here. For engine speed recommendations, refer to theinstructions provided with the equipment powered by this engine. To stop the engine in an emergency, simply turn the engine switch to the OFF position. Under normal conditions, use the following procedure. 1. Move the throttle lever to the SLOW position. Some engine applications use a remotely-mountedthrottle control rather than the engine-mounted throttle lever shown...

Good maintenance is essential for safe, economi-cal, and trouble-free operation. It will also help reduce air pollution. Some of the most important safety precautions are as follows. (Note: We cannot warn you of every conceivable hazard that can arise in performing maintenance. Only you can decide whether or not you should perform a given task.) Failure to properly follow maintenance instructions and precautions can cause you to be seriously hurt or killed. Always follow the procedures and precautionsin the owners manual. Improperly maintaining this engine, or failure tocorrect a problem before...

However, to avoid the inconvenience of an unex-pected shutdown, fill to the upper limit, and check the oil level regularly. 4. Screw in the filler cap/dipstick securely. > Remove the air cleaner cover and inspect the filter. Clean or replace dirty filter elements. Always replace damaged filter elements. If equipped with an oil-bath air cleaner, also check the oil level. > Oil is a major factor affecting performance andservice life. Use 4-stroke automotive detergent oil. SAE 10W-30 is recommended for general use.Other viscosities shown in the chart may be used when the average temperature in your...

1. Remove the wing nutfrom the air cleaner cover, and remove the air cleaner cover. 2. Remove the wing nutfrom the air filter, and remove the filter. 3. Remove the foam filterfrom the paper filter. 4. Inspect both air filterelements, and replace them if they are dam- aged. Always replace the paper air filter element at the scheduled interval.5. Clean the air filter elements if they are to bereused. Paper air filter element: Tap the filter element sev-eral times on a hard surface to remove dirt, or blow compressed air [not exceeding 30 psi (207 kPa)] through the filter element from the inside....

1. Move the fuel valve to the OFF position, andthen remove the fuel sediment cup and O-ring. Gasoline is highly flammable and explosive. Youcan be burned or seriously injured when han- dling fuel. Keep heat, sparks and flame away.ՕHandle fuel only outdoors. Wipe up spills immediately. 2. Wash the sediment cup and O-ring in nonflam-mable solvent, and dry them thoroughly. 3. Place the O-ring in the fuel valve, and install thesediment cup. Tighten the sediment cup securely. 4. Move the fuel valve to the ON position, andcheck for leaks. Replace the O-ring if there is any leakage. Aloose spark plug...
