2. Check and clean the inlet screen. Pull the air

Paper Element

Figure 10. Removing Elements.

3. After the paper element is removed, check the

condition of the inner element. It should be

replaced whenever it appears dirty, typically

every other time the main element is replaced or

every 600 hours. Clean the area around the base

of the inner element before removing it, so dirt

does not get into the engine.

4. Do not wash the paper element and inner

element or use compressed air, this will damage

the elements. Replace dirty, bent or damaged

elements with new genuine Kohler elements as

required. Handle the new elements carefully;

do not use if the sealing surfaces are bent or

damaged.

5. Check all parts for wear, cracks, or damage, and

make sure ejector area is clean. See Figure 11.

Replace any damaged components.

Inner Element

6. Install the new inner element, followed by the

paper element. Slide each fully into place in the

air cleaner housing.

7. Reinstall the end caps and secure with the

retaining clips. See Figure 1.

Clean Air Intake/Cooling Areas

To ensure proper cooling, make sure the fixed guard,

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. Reinstall the

blower housing and other cooling shrouds.

NOTE: Operating the engine with a blocked fixed

guard, dirty or plugged cooling fins, and/or

cooling shrouds removed, will cause engine

damage due to overheating.

Ignition System

EFI Engines incorporate a computer-controlled battery

ignition system with individual coils. Other than

periodically checking/replacing the spark plugs, no

maintenance, timing, or adjustments are necessary or

possible with this system.

Check Spark Plugs

Every 200 hours of operation, remove the spark plugs,

check condition, and reset the gap or replace with

new plugs as necessary. The standard spark plug is a

Champion

RC12YC (Kohler Part No. 12 132 02-S). RFI

compliant engines use a Champion

Part No. 25 132 14-S) spark plug. A high-performance

spark plug, Champion

Series engines, Kohler Part No. 25 132 12-S) is also

available. Equivalent alternate brand plugs can also be

used.
