Cleaning the cylinder fins (Fig. 3-6)
When wood chips are caught between cylinder
fins, 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.
Cleaning the muffler (Fig. 3-7, 7B)
Remove the muffler and spark arrestor (if so
equipped), and clean out any excess carbon
from the exhaust port or muffler inlet every 100
hours of operation.
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.
