Cleaning the cylinder fi ns (Fig. 35)

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

resulted from use. Clean the unit with a clean rag, or
the use of high pressure air hose. Put a few drops
of two-cycle engine oil into the cylinder through the
spark plug hole, and spin the engine over several
times to distribute oil.
Cover the unit and store it in a dry area.
