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.

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.

Oil Type

Use high quality detergent oil of API (American Petroleum Institute) service class SG, SH, SJ or higher.

A logo or symbol on oil containers identiﬁes the API service class and SAE viscosity grade. See Figure 3.

Select the viscosity based on the air temperature at the time of operation as shown in the following table.

Raised Air Cleaner Access Door

*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.

Figure 3. Oil Container Logo.

Refer to Maintenance Instructions beginning on page 7 for detailed oil check, oil change, and oil ﬁlter change procedures.

Fuel Recommendations

WARNING: Explosive Fuel!

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.

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.

NOTE: If the engine develops suﬃcient 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 oﬀ 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.

• 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!

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.

3. For a Cold Engine – Gradually return the choke control to the oﬀ 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 oﬀ 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 suﬃcient 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.
