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. It is also recommended that a consistent brand of oil be used. 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 SJ or higher. Select

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

RECOMMENDED SAE VISCOSITY GRADES

10W-30

5W-20, 5W-30

Electric Starter

NOTE: Synthetic oils meeting the listed

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

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 SJ or higher oil

or extending oil change intervals longer than recommended can cause engine damage.

Refer to Maintenance Instructions beginning on page 8 for detailed oil check, oil change, and oil filter change procedures.

Fuel Recommendations

WARNING: Explosive Fuel!

General Recommendations

Purchase gasoline in small quantities that can be used within 30 days and store only in clean, approved containers. Do not use gasoline left over from the previous season unless treated with a fuel stabilizer (refer to Storage), to minimize gum deposits and ensure easy starting. Do not use gasoline containing Methanol, or 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 and reduces harmful exhaust emissions. Leaded gasoline is not recommended and must not be used in any models where exhaust emissions are regulated.

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 T ertiary 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.

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 affixed to the engine shrouding. Include letter suffixes, if there are any.

Record your engine identification numbers on the identification label below (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 shift lever must be exactly in neutral to prevent resistance which could keep the engine from starting.

Throttle and Choke Control Linkage Setup

The throttle and choke levers on these engines allow remote mounted control operation from either side. The linkage for the throttle and choke is connected in one of the two available hole locations; A or B in the control levers. Hole location A in each lever is used for

Outer Pull actuation. Hole Location B used for Inner Pull actuation. Most engines will have the control

linkage connected in Location A, the primary location. If the application requires opposite side control direction or function, unhook the link(s) from the small clip and reconnect in the other hole location. See Figures 5 and 6.
