Battery

A 12 volt battery is normally used. Refer to the

operating instructions of the equipment this engine

powers for specific battery requirements.

If the battery charge is not sufficient to crank the

engine, recharge the battery (see page 15).

Operating

Angle of Operation

This engine will operate continuously at angles up to

20°. Check oil level to assure crankcase oil level is at

the “FULL” mark on the dipstick.

Refer to the operating instructions of the equipment

this engine powers. Because of equipment design or

application, there may be more stringent restrictions

regarding the angle of operation.

NOTE: Do not operate this engine continuously at

angles exceeding 20° in any direction. Engine

damage could result from insufficient

lubrication.

Cooling

NOTE: If debris builds up on the air intake screen,

radiator, or other cooling areas, stop the

engine immediately and clean. Operating the

engine with blocked or dirty air intake and

cooling areas can cause extensive damage

due to overheating. See ‘‘Clean Air Intake/

Cooling Area’’, page 14.

High Temperature Sensor

Some engines are equipped with a high temperature

sensor mounted in the cooling system. If the safe

operating temperature is exceeded, it will either shut

off the engine or activate a warning signal, depending

on the application.

If the warning light illuminates or engine kills indicating

excessive operating temperatures:

1. Make sure all air intake and cooling surfaces are

clean and free of debris.

2. After engine has sufficiently cooled, check the

coolant level in system to make sure it is not low.

See ‘‘Checking Coolant Level’’, page 10.

3. Check the system for external leaks.

4. If the cause is none of the above or cannot be

identified, contact an Authorized Kohler Engine

Dealer for appropriate diagnosis and correction.

WARNING: Hot Parts!

Engine components can get extremely hot from

operation. To prevent severe burns, do not touch these

areas while the engine is running, or immediately after

it is turned off. Never operate the engine with heat

shields or guards removed.

Engine Speed

NOTE: Do not tamper with the governor setting to

increase the maximum engine speed.

Overspeed is hazardous and will void the

engine warranty. The maximum allowable high

idle speed for these engines is 3750 RPM.
