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. A minimum of 22 ounces

(651 mL) is required. 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.

NOTE: Using other than service class SG, SH, SJ or

higher oil or extending oil change intervals

longer than recommended can cause engine

damage.

A logo or symbol on oil containers identifies the API

service class and SAE viscosity grade. See Figure 3.

*Use of synthetic oil having 5W-20 or 5W-30 rating is

acceptable.

**Synthetic oils will provide better starting in extreme

cold (below -10°F).

Figure 2. Viscosity Grades Table.

Refer to Maintenance Instructions beginning on

age 7 for detailed oil check, oil change, and oil

filter change rocedures.

Fuel Recommendations

WARNING: Ex losive 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 left over from the previous season,

to minimize gum deposits in your fuel system and to

insure easy starting.

Do not add oil to the gasoline.

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. Be aware

however, that the cylinder head will require more

frequent service.

Engine dentification Numbers

When ordering parts, or in any communication involving

an engine, always give the Model, S ecification, and

Serial Numbers of the engine.

The engine identification numbers appear on a decal

(or decals) affixed to the engine shrouding. Include

letter suffixes, if there are any.

Record your engine identification numbers on the

Check Oil Level

The importance of checking and maintaining the proper

oil level in the crankcase cannot be overemphasized.

Check oil BEFORE EACH USE as follows:

1. Make sure the engine is stopped, level, and is

cool so the oil has had time to drain into the sump.

2. To keep dirt, debris, etc., out of the engine, clean

the area around the oil fill/check plug before

removing it.

3. Unthread and remove the oil fill/check plug.

4. The level should be up to but not over, the point of

overflowing the filler neck.

5. If the level is low, add oil of the proper type, up to

the point of overflowing the filler neck. (Refer to

Oil Type on page 4.) Always check the level

before adding more oil.

NOTE: To prevent extensive engine wear or

damage, always maintain the proper oil

level in the crankcase. Never operate the

engine with the oil level below the point of

overflowing the filler neck.

Change Oil

For a new engine, change oil after the first hour of

operation. Thereafter, change oil after every 25 hours

of operation.

For an overhauled engine or those rebuilt with a

new short block, use 10W-30  weight service class

SG, SH, SJ or higher oil for the first hour of operation.

Change the oil after this initial run-in period. Refill with

service class SG, SH, SJ or higher oil as specified in

the Viscosity Grades table (Figure 2) on page 4.

Change the oil while the engine is still warm. The oil

will flow freely and carry away more impurities. Make

sure the engine is level when filling, checking, or

changing the oil.

Change the oil as follows (see Figure 7):

1. To keep dirt, debris, etc., out of the engine, clean

the area around the oil fill cap/dipstick before

removing it.

2. Remove the oil drain plug and oil fill/check plug.

Be sure to allow ample time for complete

drainage.

3. Reinstall the drain plug. Make sure it is tightened

to 17.6 N·m (13 ft. lb.) torque.

4. Fill the crankcase, with new oil of the proper type,

up to the point of overflowing the filler neck. Refer

to Oil Type on page 4. Always check the level

before adding more oil.

5. Reinstall the oil fill/check plug and tighten

securely.

Figure 6. Location of Oil Drain and Check Plugs.

NOTE: Just because you can see oil in the crankcase

doesn't mean the level is in the safe range.

Bring the level up to the point of overflowing

the filler neck.

Clean Air Intake/Cooling Areas

To ensure proper cooling, make sure the grass screen,

cooling fins, and other external surfaces of the engine

are kept clean at all times.

Every 100 hours of operation (more often under

extremely dusty, dirty conditions), remove the blower

housing and other cooling shrouds. Clean the cooling

fins and external surfaces as necessary. Make sure the

cooling shrouds are reinstalled.

NOTE: Operating the engine with a blocked grass

screen, dirty or plugged cooling fins, and/or

cooling shrouds removed, will cause engine

damage due to overheating.

Ignition System

This engine is equipped with a dependable electronic

magneto ignition system. Other than periodically

checking/replacing the spark plug, no maintenance,

timing, or ad ustments are necessary or possible with

this system.

In the event starting problems should occur which are

not corrected by replacing the spark plug, see your

Kohler Engine Service Dealer for trouble analysis.

Check Spark Plug

Annually, remove the spark plug, check condition, and

reset the gap or replace with new plug as necessary.

Use a Champion® type RC12YC (or equivalent) spark

plug.

1. Before removing the spark plug, clean the area

around the base of the plug to keep dirt and debris

out of the engine.

2. Remove the plug and check its condition.

Replace the plug if worn or reuse is questionable.

NOTE: Do not clean the spark plug in a machine

using abrasive grit. Some grit could

remain in the spark plug and enter the

engine causing extensive wear and

damage.

3. Check the gap using a wire feeler gauge. Ad ust

the gap to 1.02 mm (0.040 in.) by carefully

bending the ground electrode. See Figure 9.
