The engine is equipped with a replaceable, high density

paper air cleaner element. See Figure 4-5.

1. Knobs (qty.2)

2. Cover

3. Paper element

4. Air filter latch

Figure 4-5 Air Cleaner Components

Check the air cleaner daily or before starting the engine.

Check for a buildup of dirt and debris around the air

cleaner system. Keep this area clean. Also check for

loose or damaged components. Replace all bent or

damaged air cleaner components.

Note: Operating the engine with loose or damaged air

cleaner components could allow unfiltered air

into engine causing premature wear and failure.

Paper Element Service

Replace the paper element at the intervals indicated in

the service schedule. See Section 4.2 for the service

schedule.

See Figure 4-5 for the air cleaner

components.

1. Loosen the two cover retaining knobs and remove

the cover.

2. Rotate the air filter latch counterclockwise to

unlock, then remove the paper element.

3. Do not wash the paper element or use pressurized

air, as this will damage the element. Replace a

dirty, bent, or damaged element with a genuine

Kohler element. Handle new elements carefully;

do not use if the sealing surfaces are bent or

damaged.

4. When servicing the air cleaner, check the air

cleaner base and latch. Make sure it is secured and

not bent or damaged. Also, check the element

cover for damage or improper fit. Replace all

damaged air cleaner components.

Note: If any loose dirt or debris fell on the air cleaner

base when the element was removed, carefully

remove it and wipe the base clean. Be careful that

none of it drops into the intake throat.

5. Reinstall the paper element onto the air cleaner

base. Make sure the element is flat and properly

seated. Rotate the latch clockwise, over the

molded lip on the element.

6. Install the air cleaner cover and secure with the two

retaining knobs.

7. When element replacement is necessary, order

genuine Kohler parts.

4.6 Cooling System

tp6515

The engine fan draws cooling air through the openings

in the sides and end near the battery. The alternator fan

draws cooling air through openings on the side walls of

the enclosure. The cooling air mixes with the engine

exhaust and is discharged at the exhaust outlet. See

Figure 4-6. To prevent generator set damage caused by

overheating, keep the housing cooling inlets and outlets

clean and unobstructed at all times.

Note: Do not block the generator set cooling air inlets or

mount

Overheating and severe generator damage may

occur.

1. Exhaust outlet

2. Alternator air intake (both sides)

3. Engine air intake
