Typical COURAGE® Series Vertical Shaft Engine. Oil Recommendations Using the proper type and weight of oil in the crankcase is extremely important. So is checking oil daily and changing oil regularly. Failure to use the correct oil, or using dirty oil, causes premature engine wear and failure.
Do not add oil to the gasoline. Do not overfill the fuel tank. Leave room for the fuel to expand. Fuel Type For best results use only clean, fresh, unleaded gasoline with a pump sticker octane rating of 87 or higher. In countries using the Research method, it should be 90 octane minimum. Unleaded gasoline is recommended as it leaves less combustion chamber deposits. Leaded gasoline may be used in areas where unleaded is not available and exhaust emissions are not regulated.

2. Make sure the equipment is in neutral. 3. Activate the starter switch. Release the switch as soon as the engine starts. b. For engines equipped with a shutdown solenoid: Position the throttle control between half and full throttle; then stop the engine. NOTE: Do not crank the engine continuously for more than 10 seconds at a time. If the engine does not start, allow a 60 second cool down period between starting attempts. Failure to follow these guidelines can burn out the starter motor.
Maintenance Instructions Maintenance, repair, or replacement of the emission control devices and systems, which are being done at the customers expense, may be performed by any non-road engine repair establishment or individual. Warranty repairs must be performed by an authorized Kohler service outlet. WARNING: Accidental Starts! Disabling engine. Accidental starting can cause severe injury or death.
2. Remove the oil drain plug and oil fill cap/dipstick. Be sure to allow ample time for complete drainage. “F” Mark Operating Range 3. Remove the old filter and wipe off the mounting pad. 4. Reinstall the drain plug. Make sure it is tightened to 14 N·m (125 in. lb.) torque. Figure 7. Oil Level Dipstick. 5. If the level is low, add oil of the proper type, up to the “F” mark on the dipstick. (Refer to “Oil Type” on page 4.) Always check the level with the dipstick before adding more oil.
Service Precleaner and Air Cleaner Element This engine is equipped with a replaceable, high density paper air cleaner element. Some engines are also equipped with an oiled, foam precleaner, located in the outer air cleaner cover. See Figure 9. Check the air cleaner daily or before starting the engine. Check for a buildup of dirt and debris around the air cleaner system. Keep this area clean. Also check for loose or damaged components. Replace all bent or damaged air cleaner components.
Due to the deep recess around the spark plug, blowing out the cavity with compressed air is usually the most effective method for cleaning. The spark plug is most accessible when the blower housing is removed for cleaning. 2. Remove the plug and check its condition. Replace the plug if worn or reuse is questionable. Figure 11. Installing Air Cleaner Element.
Fuel Filter Some engines are equipped with an in-line fuel filter. Periodically inspect the filter and replace when dirty. Replacement is recommended annually or every 100 hours. Use a genuine Kohler filter. • Make sure the fuel tank is filled with clean, fresh gasoline. • Make sure the fuel tank cap vent is not blocked and that it is operating properly. Carburetor Troubleshooting and Adjustments • If the fuel tank is equipped with a shut-off valve, make sure it is open.
*NOTE: The actual low idle speed depends on the application – refer to equipment manufacturer’s recommendations. The recommended low idle speed for basic engines is 1500 RPM. To ensure best results when setting the low idle fuel needle, the low idle speed must not exceed 1500 RPM (± 75 RPM). Lean Adjust to Midpoint Rich Troubleshooting When troubles occur, be sure to check the simple causes which, at first, may seem too obvious to be considered.
