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.

*Cleanout kits 25 755 20-S (black) or 25 755 21-S

(gold) allow inspection and cleanout of the cooling

fins, without removing the blower housing.

Ignition System

Carbureted Engines - Use an electronic Capacitive

Discharge (CD) ignition system. Other than

periodically checking/replacing the spark plugs, no

maintenance, timing, or adjustments are necessary or

possible with this 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

complaint engines use a Champion

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

spark plug, Champion

Platinum 3071 (used on Pro

Series engines, Kohler Part No. 25 132 12-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.

Battery Charging

Batteries produce explosive hydrogen gas while being charged.

To prevent a fire or explosion, charge batteries only in well

ventilated areas. Keep sparks, open flames, and other sources of

ignition away from the battery at all times. Keep batteries out of

the reach of children. Remove all jewelry when servicing

batteries.

Before disconnecting the negative (-) ground cable, make sure

all switches are OFF. If ON, a spark will occur at the ground

cable terminal which could cause an explosion if hydrogen gas

or gasoline vapors are present.

Fuel System

The EFI fuel system operates under high pressure, and the fuel

filter and fuel line used must be approved system components

only. Use of substitute parts can result in system failure,

gasoline leakage and possible explosion.

Fuel Filter

Carbureted Engines: Most engines are equipped with

an in-line fuel filter. Periodically inspect the filter and

replace with a genuine Kohler filter every 200

operating hours.

3. Check the gap using a wire feeler gauge. Adjust

the gap to 0.76 mm (0.030 in.) by carefully

bending the ground electrode. See Figure 14.
