Cleaning
the
cylinder
fi
ns
(Fig.
39)
When wood chips are caught between cylinder
fi
ns (40), 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.
For long-term storage
Drain all fuel from the fuel tank. Start and let engine run until it stops.
Repair any damage which has 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.
