Cylinder Head Cooling Fins
It is essential for performance and longevity of the
air-cooled engine to keep the cylinder head cooling
fins 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 airflow. If there is little or no airflow, clean the
cooling fins as described below.
Every 100 hours, inspect and clean the cooling fins
(more often when operating in extremely dusty, dirty
conditions). Remove the two (2) cooling fin access
panels in the engine shroud and clean the cooling
fins and external surfaces using compressed air.
Make sure to reinstall the access panels before op-
erating the engine.
