E. ENGINE FUEL MIXTURE
Ydur chain saw is powered by a two-cycle
engine?-Which requires a fuel mixture of
regula_gasoline, leaded or unleaded,'and a
high ,quality engine, oil- specially made- for
2-cycle, air-cooled engines. The internal
design of the 2-cycle engine requires lubrica-
tion of moving parts. Lubrication is provided
when you use the recommended mixture of
gasoline and oil,
Gasoline must be clean and not over two
months old. After a short period of time,
gasoline begins to chemically break down
and wil! form compounds that can cause hard
starting and damage in 2-cycle engines.
The correct measure of gasoline to oil is very
importanL
--Too much oil in the mixture will foul the
spark plug.
--Too little oil will cause the engine to over-
heat and freeze up.
Mix the ,fuel thoroughly in a separate con-
tainer since gasoline and oil do not readily
combine,
