Cleaning the cylinder fins (Fig, 35)
When wood chips are caught between cylinder fins
(38), the engine may overheat, resulting in lower
output. To avoid this, always keep cylinder fins and
fan case clean.
Every 100 operating hours, or once a year (more
often if conditions require), clean fins and external
surfaces of engine of dust, dirt and oil deposits
which can contribute to improper cooling.
