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 described below.
DANGER
Make sure to keep hands clear of exhaust
pipe, muf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.
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.
