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, and feeling the
cooling airow. If there is little or no airow, clean
the cooling ns as follows:
DANGER
Make sure to keep hands clear of exhaust
pipe, mu󰀪er, and moving parts when
checking airow.
Every 100 hours, inspect and clean the cooling ns
(more often when operating in extremely dusty, dirty
conditions). Remove the two (2) cooling n access
panels in the engine shroud and clean the cooling
ns and external surfaces using compressed air.
Make sure to reinstall the access panels before op-
erating the engine.
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 resulting in engine overheating.
NOTE: If dirt is packed into the cooling ns it may
be necessary to remove the engine shroud in order
to thoroughly clean the cooling ns.

IMPORTANT: Yearly, it is good maintenance prac-
tice to remove the engine cooling shroud and clean
the cylinder head cooling ns thoroughly to prevent
overheating and extend engine life. Make sure cool-
ing shroud is reinstalled properly. This procedure
will require removing the engine from the chassis.
