INSPECTION
Operation in Freezing Weather
When operating in freezing weather, be certain that the
proper amount of antifreeze (Table 6) has been added.
CLEANING THE RADIATOR
The engine may overheat if the radiator fins become
overloaded with dust or debris. Periodically clean the
radiator fins with compressed air. Cleaning inside the
machine is dangerous, so clean only with the engine turned
off and the negative battery terminal disconnected.
AIR CLEANER
Periodic cleaning/replacement of the engine air cleaner
is necessary. Inspect the air cleaner as referenced in the
Maintenance section of this manual.
FAN BELT TENSION
A slack fan belt may contribute to overheating or to
insufficient charging of the battery. Inspect the fan belt for
damage or wear and adjust it in accordance with the Kohler
Engine Owner’s Manual.
The fan belt tension is proper if the fan belt bends
0.4–0.6 inches (10–15 mm) when depressed with the thumb
as shown in Figure 8.
