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,
