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.
Oil Type
Use high quality detergent oil of API (American Petroleum Institute) service class SG, SH, SJ or higher. Select the viscosity based on the air temperature at the time of operation as shown in the following table.

TEMPERATURE RANGE EXPECTED BEFORE NEXT OIL CHANGE
*Use of synthetic oil having 5W-20 or 5W-30 rating is acceptable, up to 4°C (40°F).
**Synthetic oils will provide better starting in extreme cold below
23°C (-10°F).
Figure 2. Viscosity Grades Table.
NOTE: Using other than service class SG, SH, SJ or higher oil or extending oil change intervals longer than recommended can cause engine damage.
NOTE: Synthetic oils meeting the listed classifications may be used with oil changes performed at the recommended intervals. However to allow piston rings to properly seat, a new or rebuilt engine should be operated for at least 50 hours using standard petroleum based oil before switching to synthetic oil.
A logo or symbol on oil containers identifies the API service class and SAE viscosity grade. See Figure 3.

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 Recommendations
Purchase gasoline in small quantities and store in clean, approved containers. A container with a capacity of 2 gallons or less with a pouring spout is recommended. Such a container is easier to handle and helps eliminate spillage during refueling.
Do not use gasoline le over from the previous season, to minimize gum deposits in your fuel system and to ensure easy starting.
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 the 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 and reduces harmful exhaust emissions. Leaded gasoline is not recommended.
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 are not to be used and not approved. Any 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 engine. Other gasoline/ether blends are not approved.
Engine Identification Numbers
When ordering parts, or in any communication involving an engine, always give the Model, Specification, and Serial Numbers of the engine.
The engine identification numbers appear on a decal (or decals) a xed to the engine shrouding. Include le er su xes, if there are any.
Record your engine identification numbers on the identification label (Figure 4) for future reference.

Operating Instructions
Also read the operating instructions of the equipment this engine powers.
Pre-Start Checklist
•Check oil level. Add oil if low. Do not overfill.
•Check fuel level. Add fuel if low.
•Check cooling air intake areas and external surfaces of engine. Make sure they are clean and unobstructed.
•Check that the air cleaner components and all shrouds, equipment covers, and guards are in place and securely fastened.
•Check that any clutches or transmissions are
disengaged or placed in neutral. This is especially important on equipment with hydrostatic drive. The shi lever must be exactly in neutral to prevent resistance which could keep the engine from starting.
WARNING: Lethal Exhaust Gases!
Engine exhaust gases contain poisonous carbon monoxide. Carbon monoxide is odorless, colorless, and can cause death if inhaled. Avoid inhaling exhaust fumes, and never run the engine in a closed building or confined area.
Cold Weather Starting Hints
1.Be sure to use the proper oil for the temperature expected. See Figure 2 on page 4.
2.Declutch all possible external loads.
3.Be sure the ba ery is in good condition. A warm ba ery has much more starting capacity than a cold ba ery.
4.Use fresh winter grade fuel. NOTE: Winter grade gasoline has higher volatility to improve starting.
Do not use gasoline le over from summer.
Starting
1.Place the thro le control midway between the slow and fast positions. Place the choke control into the on position.
2.Start the engine by activating the key switch. Release the switch as soon as the engine starts.
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 a empts. Failure to follow these guidelines can burn out the starter motor.
NOTE: If the engine develops su cient speed to disengage the starter but does not keep running (a false start), engine rotation must be allowed to come to a complete stop before a empting to restart the engine.
If the starter is engaged while the flywheel is rotating, the starter pinion and flywheel ring gear may clash, resulting in damage to the starter.
If the starter does not turn the engine over, shut o starter immediately. Do not make further a empts to start the engine until the condition is corrected. Do not jump start using another ba ery (refer to Ba ery). See your Kohler Engine Service Dealer for service assistance.
3.For a Cold Engine – Gradually return the choke control to the o position a er the engine starts and warms up.
The engine/equipment may be operated during the warm-up period, but it may be necessary to leave the choke partially on until the engine warms up.
4.For a Warm Engine – Return choke to o position as soon as engine starts.
Stopping
1.Remove the load by disengaging all PTO driven a achments.
2.For Engines without a Shutdown Solenoid:
Move the thro le to the slow or low idle position. Allow the engine to run at idle for 30-60 seconds; then stop the engine.
For Engines Equipped with a Shutdown Solenoid: Position the thro le control between half and full thro le; then stop the engine.
Battery
A 12 volt ba ery is normally used. Refer to the operating instructions of the equipment this engine powers for specific ba ery requirements.
If the ba ery charge is not su cient to crank the engine, recharge the ba ery.
Operating
Angle of Operation
This engine will operate continuously at angles up to 25°. Check oil level to assure crankcase oil level is at the FULL or “F” mark on the dipstick.
