Oil Recommendations
Using the proper type and weight of oil in the engine is extremely important, as is daily checking of oil level and changing oil regularly. Failure to use the correct oil, or using dirty oil, will cause premature engine wear and failure. Refer to Oil Check/Change maintenance instructions.
Oil Type
Use high-quality oil that ranks at or above the American Petroleum Institute's (API) SJ service class. Select the oil's viscosity based on air temperature at the time of operation, as shown in Figure 2.
RECOMMENDED SAE VISCOSITY GRADES
Figure 2. Viscosity Grades Table.
Use service class SJ rated oil or higher. Do not extend the oil change intervals longer than recommended as this can cause engine damage, and may void the warranty. An API symbol on the oil container identifies the service class and SAE viscosity grade. See Figure 3.
Figure 3. Oil Container Logos.
Fuel Recommendations
WARNING: Explosive Fuel!
Gasoline is extremely flammable and its vapors can explode if ignited. Store gasoline only in approved containers, in well ventilated, unoccupied buildings, away from sparks or flames. Do not fill the fuel tank while the engine is hot or running since spilled fuel could ignite if it comes in contact with hot parts or sparks from ignition. Do not start the engine near spilled fuel. Never use gasoline as a cleaning agent.
General Fuel Recommendations
Purchase gasoline in small quantities and store in clean, approved containers. Use a container with a capacity of two gallons or less with a pouring spout is recommended, as it is easier to handle and helps eliminate spillage during refueling. To minimize gum deposits in fuel system, do not use gasoline left over from previous season. 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 an 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. Be aware that the cylinder head may require more frequent service.
Gasoline/Alcohol Blends
Gasohol (up to 10% ethyl alcohol, 90% unleaded gasoline by volume) is approved as a fuel for Kohler engines. Other gasoline/alcohol blends including E20 and E85 should not be used. Failures resulting from use of these fuels will not be warranted.
Gasoline/Ether Blends
Methyl Tertiary Butyl Ether (MTBE) and unleaded gasoline blends (up to a maximum of 15% MTBE by volume) are approved as a fuel for Kohler engines. Other gasoline/ether blends are not approved.
Fuel Line
These engines use Low Permeation SAE 30 R7 rated fuel lines, certified to meet emission requirements. Standard fuel line may not be used. Order replacement hose (Kohler part number 25 111 40-S) through a Kohler authorized service center.
Fuel Shut-off Valve (If Equipped)
Turn to ON fuel flow, rotate fuel shut-off valve towards the engine. To turn OFF the fuel flow, rotate the fuel shut-off valve away from the engine. See Figure 4.
Figure 4. Fuel Shut-off Valve (ON Position Shown).
NOTE: Before transporting the engine, ensure the fuel valve is in the OFF position to prevent fuel spillage.
Fuel Filter (If Equipped)
Replace with a Kohler fuel filter yearly or every 50 hours of operation (Kohler part number 14 050 16-S). Removing the air filter will allow easy access to the fuel filter for servicing. See Figure 5.
Figure 5. Fuel Filter (Air Filter Removed).

NOTE: Do not attempt to service or replace major engine components, or any items that require special timing or adjustment procedures. This work should be performed by a Kohler authorized service center.
Storage
If the engine will be out of service for two months or more, follow these storage procedures:
- Clean the exterior surfaces of the engine.
- Change the oil while the engine is still warm from operation. See Oil Change.
- The engine must be run until the fuel tank is completely emptied, or the gasoline must be treated with a stabilizer to prevent deterioration. If a stabilizer is used, follow the manufacturer's
instructions. Fill the tank with fresh gasoline and run the engine for 2-3 minutes to ensure stabilized fuel has entered the carburetor.
- Remove the spark plug. Add one tablespoon of engine oil into the spark plug hole. Reinstall the plug, but do not connect the plug lead. Crank the engine two or three revolutions.
- Remove the spark plug. Cover the spark plug hole with your thumb and turn the engine over until the piston is at the top of its stroke (pressure against the thumb is greatest). Reinstall the spark plug, but do not connect the spark plug lead.
- Store the engine on a level surface in a clean, dry place. Never store the unit where there is an open flame, spark, or pilot light such as on a water heater or other appliances.
COURAGE® ENGINE LIMITED WARRANTY
Kohler Co. warrants to the original retail consumer that each new COURAGE® engine sold by Kohler Co. will be free from manufacturing defects in materials or workmanship in normal residential homeowner service for a period of two (2) years from date of purchase, provided it is operated and maintained in accordance with Kohler Co.'s instructions and manuals.

The warranty period begins on the date of purchase by the original retail consumer or commercial end user. "Residential homeowner service" means residential use by a retail consumer. "Commercial use" means all other uses, including use for commercial, or rental purposes. Once in commercial use, the engine will thereafter be considered a commercial use engine for the purposes of this warranty.
Our obligation under this warranty is expressly limited, at our option, to the replacement or repair at Kohler Co., Kohler, Wisconsin 53044, or at a service facility designated by us of such parts as inspection shall disclose to have been defective.
EXCLUSIONS:

Kohler Co. AND/OR THE SELLER SHALL NOT BE LIABLE FOR SPECIAL, INDIRECT, INCIDENTAL, OR CONSEQUENTIAL DAMAGES OF ANY KIND, including but not limited to labor costs or transportation charges in connection with the repair or replacement of defective parts.
IMPLIED OR STATUTORY WARRANTY, INCLUDING WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE, ARE EXPRESSLY LIMITED TO THE DURATION OF THIS WRITTEN WARRANTY. We make no other express warranty, nor is any one authorized to make any on our behalf.
Some states do not allow limitations on how long an implied warranty lasts, or the exclusion or limitation of incidental or consequential damages, so the above limitation or exclusion may not apply to you.

FEDERAL AND CALIFORNIA EMISSION CONTROL SYSTEMS LIMITED WARRANTY SMALL OFF-ROAD ENGINES
The U.S. Environmental Protection Agency (EPA), the California Air Resources Board (CARB), and Kohler Co. are pleased to explain the Federal and California Emission Control Systems Warranty on your small off-road equipment engine. In California beginning in 2006, "emissions" means both exhaust and evaporative emissions. For California, engines produced in 2006 and later must be designed, built and equipped to meet the state's stringent anti-smog standards. In other states, 1997 and later model year engines must be designed, built and equipped, to meet the U.S. EPA regulations for small non-road engines. The engine must be free from defects in materials and workmanship which cause it to fail to conform with U.S. EPA standards for the first two years of engine use from the date of sale to the ultimate purchaser. Kohler Co. must warrant the emission control system on the engine for the period of time listed above, provided there has been no abuse, neglect or improper maintenance.
The emission control system may include parts such as the carburetor or fuel injection system, the ignition system, and catalytic converter. Also included are the hoses, belts and connectors and other emission related assemblies.
Where a warrantable condition exists, Kohler Co. will repair the engine at no cost, including diagnosis (if the diagnostic work is performed at an authorized dealer), parts and labor.
MANUFACTURER'S WARRANTY COVERAGE
Engines produced in 2006 or later are warranted for two years in California. In other states, 1997 and later model year engines are warranted for two years. If any emission related part on the engine is defective, the part will be repaired or replaced by Kohler Co. free of charge.
OWNER'S WARRANTY RESPONSIBILITIES
(a) The engine owner is responsible for the performance of the required maintenance listed in the owner's manual. Kohler Co. recommends that you retain all receipts covering maintenance on the engine, but Kohler Co. cannot deny warranty solely for the lack of receipts or for your failure to assure that all scheduled maintenance was performed.
(b) Be aware, however, that Kohler Co. may deny warranty coverage if the engine or a part has failed due to abuse, neglect, improper maintenance or unapproved modifications.
(c) For warranty repairs, the engine must be presented to a Kohler authorized service center as soon as a problem exists. Call Kohler Co. toll free at 1-800-544-2444, or access our Web site at www.kohlerengines.com for the names of the nearest service centers. Warranty repairs should be completed in a reasonable amount of time, not to exceed 30 days.
If you have any questions regarding warranty rights and responsibilities, you should contact Kohler Co. at 1-920-457-4441 and ask for an engine service representative.
COVERAGE
Kohler Co. warrants to the ultimate purchaser and each subsequent purchaser that the engine will be designed, built and equipped, at the time of sale, to meet all applicable regulations. Kohler Co. also warrants to the initial purchaser and each subsequent purchaser, that the engine is free from defects in materials and workmanship which cause the engine to fail to conform with applicable regulations for a period of two years.
Engines produced in 2006 or later are warranted for two years in California. For 1997 and later model years, EPA requires manufacturers to warrant engines for two years in all other states. These warranty periods will begin on the date the engine is purchased by the initial purchaser. If any emission related part on the engine is defective, the part will be replaced by Kohler Co. at no cost to the owner. Kohler Co. is liable for damages to other engine components caused by the failure of a warranted part still under warranty.
Kohler Co. shall remedy warranty defects at any authorized Kohler Co. engine dealer or warranty station. Warranty repair work done at an authorized dealer or warranty station shall be free of charge to the owner if such work determines that a warranted part is defective. Continued on the next page

MAINTENANCE AND REPAIR REQUIREMENTS
The owner is responsible for the proper use and maintenance of the engine. Kohler Co. recommends that all receipts and records covering the performance of regular maintenance be retained in case questions arise. If the engine is resold during the warranty period, the maintenance records should be transferred to each subsequent owner. Kohler Co. reserves the right to deny warranty coverage if the engine has not been properly maintained; however, Kohler Co. may not deny warranty repairs solely because of the lack of repair maintenance or failure to keep maintenance records.
Normal maintenance, replacement or repair of emission control devices and systems may be performed by any repair establishment or individual; however, warranty repairs must be performed by a Kohler authorized service center. Any replacement part or service that is equivalent in performance and durability may be used in non-warranty maintenance or repairs, and shall not reduce the warranty obligations of the engine manufacturer.
