7. When replacement is necessary order genuine

Kohler parts.

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 adjustments 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

Every 200 hours of operation, remove the spark plug,

check condition, and reset the gap or replace with a

new plug as necessary. The standard spark plug is a

Champion

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

high-performance spark plug, Champion

Premium

Gold 2071 (used on Pro Series engines, Kohler Part

No. 12 132 06-S) is also available. Equivalent alternate

brand plugs can also be used.

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.

Service Paper Element

Every 100 hours of operation replace the paper

element, if equipped with a precleaner. Check every 25

hours of operation if not equipped with a precleaner.

(More often under extremely dusty or dirty conditions.)

1. Loosen the air cleaner cover knob and remove the

cover. Remove the wing nut and remove the air

cleaner element with precleaner (if so equipped).

Remove the precleaner from the element and

service as necessary.

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 the sealing surfaces are

bent or damaged.

3. When servicing the air cleaner, check the air

cleaner base. Make sure it is secured and not

damaged. Also, check the air cleaner cover for

damage or improper fit. Replace all damaged air

cleaner components.

4. 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. Check the

condition of the rubber seal on the air cleaner

stud. If condition is questionable in any way,

replace it with the new seal packaged with the

replacement element.

5. Install the precleaner over the element. Install the

element with precleaner on the base and secure it

with the wing nut. Reinstall the cover and tighten

the knob securely.

6. When replacement is necessary order genuine

Kohler parts.
