Clean Air Intake/Cooling System

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 50 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

ignition system. Other than periodically checking/

replacing the spark plugs, no maintenance, timing, or

adjustments are required with this system. In the event

starting problems should occur which are not corrected

by replacing the spark plugs, see your Kohler Engine

Service Dealer for trouble analysis.

Precleaner and Air Cleaner Element

This engine is equipped with a high density paper air

cleaner element. Some specifications are also

equipped with an optional oiled foam precleaner which

surrounds the paper element.

Service Precleaner

If so equipped, wash and reoil the precleaner every

25 hours of operation (more often under extremely

dusty or dirty conditions).

1. Remove wing nuts, air cleaner cover, element

cover seal, and element cover.

2. Remove precleaner from paper element. Wash

the precleaner in warm water with detergent.

3. Rinse the precleaner thoroughly until all traces of

detergent are eliminated. Squeeze out excess

water (do not wring). Air dry.

4. Saturate precleaner in clean, fresh engine oil and

squeeze out excess oil.

5. Reinstall precleaner over paper element.

Service Paper Element

Every 100 hours of operation (more often under

extremely dusty or dirty conditions) replace the

element.

1. Remove the precleaner (if so equipped) from

paper element.

2. 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 sealing surfaces are bent

or damaged.

3. 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,

seals, and breather tube for damage or improper

fit. Replace all damaged air cleaner components.

NOTE: Damaged or loose components could

allow unfiltered air into the engine

causing premature wear and failure.

4. Reinstall the paper element, precleaner, element

cover, element cover seal, air cleaner cover, and

wing nut. Tighten wing nut 1/2 to 1 full turn after

nut contact cover. Do not overtighten.

Check Spark Plugs

Every 100 hours of operation, remove the spark plugs,

check condition and reset the gap, or replace with new

plugs as necessary:

1. Before removing spark plugs, clean the area

around base of plugs to keep dirt and debris out of

engine.

2. Remove plugs and check condition. Replace the

plug if worn or reuse is questionable.

NOTE: Do not clean the spark plugs 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. Adjust

the gap to 0.035 in. (0.89 mm) by carefully

bending the ground electrode. See Figure 7.

4. Reinstall the spark plugs into the cylinder heads.

Torque the spark plugs to 10-15 ft. lb.

(14-20 N·m).
