Air Intake/Cooling System

To ensure proper cooling, make sure the grass screen,
cooling fan fins, and external surfaces of the engine
are kept clean at all times.
Every 100 hours of operation (more often under
extremely dusty or 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.
*Cleanout kits, Kohler Part No. 25 755 20-S (black) or
25 755 21-S (gold), are recommended to aid
inspection and cleanout of the cooling fins. See
Figure 4-15.
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.
