Air Cleaner Service
Use the following procedure to replace the paper element at the intervals specified in the service schedule. See Service
Schedule, 18 and 20 kW Models. See Figure 62 for the air cleaner components.
1. Loosen the two cover retaining knobs and remove the cover.
2. 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. 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. 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.
6. Install the air cleaner cover and secure with the two retaining knobs.
7. When element replacement is necessary, order genuine Kohler parts.

Cooling System

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 the service view section for air intake and exhaust locations. 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 other equipment above them. Overheating and severe generator
damage may occur.
