accessory.

Clean the chain Oiler port (1)
whenever possible.

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.
Chain oil filter (Fig. 3-8)
Remove the oil filter and thoroughly wash
it in solvent
Cleaning the cylinder fins (Fig. 3-9)
When wood chips are caught between cylinder fins (1),
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.
