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 airow. If there is little or no airow, clean
the cooling ns as described below.
DANGER
Make sure to keep hands clear of exhaust
pipe, mufer, and moving parts when
checking airow.
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.

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.
