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.

Check Cooling System 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 com-
pressed air. Make sure to reinstall the access
panels before oper ating the engine.
CAUTION
DO NOT use a pressure washer to clean the
cooling system on an air-cooled engine;
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 and cooling fan
thoroughly to prevent overheating and extend
engine life. Make sure cooling shroud is reinstalled
properly. This procedure will require removing the
engine from the chassis.
