Cooling Air Intake Screen
To prevent engine overheating and possible engine
damage, clean grass clippings, cha󰀨, and dirt from
the rotating engine cooling air intake screen after
every 8 hours of operation. In certain mowing
conditions (dry grass, leaves, tree “cotton”, etc.), it
may be nec essary to check and clean the screen
several times each day to prevent engine overheat-
ing.
CAUTION
Operating the engine with a blocked air
intake screen, dirty or plugged cooling
ns, and/or cooling shrouds removed will
cause engine damage from overheating.

Cylinder Head Cooling Fins
It is essential for performance and longevity of the
air-cooled engine to keep the cylinder head cooling
ns clean and free of obstruction. After every 8
hours of operation, check the performance of the
cooling system by starting the engine, holding a
hand adjacent to the cylinder head cooling air duct,
and feeling the cooling airow. If there is little or no
airow, clean the cooling ns as follows:

1. Inspect accessible cooling ns and clean with
compressed air or backpack blower as needed.
If the buildup is excessive, refer to step 2.
2. If the debris cannot be removed with com-
pressed air, it will be necessary to remove the
engine from the chassis and remove the engine
shroud for thorough cleaning. See your autho-
rized Kohler dealer for this service.
CAUTION
DO NOT use a pressure washer to clean
the cooling system on an air-cooled en-
gine, mud may form under the cooling
shroud on the cylinder head and cooling
fan.
