Poulan 3400 - Manual (Page 9)

E. ENGINE FUEL MIXTURE
• Your chain saw is powered by a two-cycle engine
which requires a fuel mixture of regular^asoline
(leaded or unleaded) and a high quality engine oii
specially made for 2-cycie air-cooled engines.
The
internal design of the 2 -cycie engine reqy ires 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 peiiod of time, gasoline begins to
chemically break down and will form compounds that
can cause hard starting and damage in
2 -cycle en­
gines.
• The correct measure of gasoline to oil is very im­
portant.
—Too much oil in the mixture will foul the spark plug.
—Too little oil will cause the engine to overheat re­
sulting in damage.
• Mix the fuel thoroughly in a container since
gasoline and oil do not readily combine. D o not
try to m ix fuel directly in the fuel tank.
1. DONOTUSE:
• BIA Oii (Boating Institute of America)—
— Does not have proper additives for air-cooled,
2 -cycIe engines and could cause damage.
• AUTOMOTIVE OIL—
— Does not have proper additives for 2-cycle
engines and could cause damage.
• GASOUNE CONTAINING ALCOHOL—
(High Test, Premium or Gasohoi)
—Stiffens critical carburetor fuel metering ele­
ments and causes engine damage from over­
heating.
— Increases vaporlock(causes hard starting).
— Attracts water causing corrosion damage.

c.
d.
e.
Pour one-half of the gasoline into an approved,
marked container.
D o not try to m ix oil and
gasoline directly in the fuel tank.
Add entire measure of 2-cycle Engine Oil.
Mix.
Add remainder of gasoline.
Mix thoroughly for one minute.
4. IMPORTANT POINTS
a. Use only recommended fuel mixtures.
b. Eliminate ail sources of sparks or flames in
the areas where fuel is mixed, poured, or
stored. There should be no smoking, open
flames or work that could cause sparks.
c. Use an approved, marked containerfor all
fuel purposes.
d. Mix and pour fuel in an outdoor area on bare
ground. Store fuel in a. cool, dry, well-
ventilated place. Gasoline vapors are harmful to
your health and can cause serious hazards
such as explosion and fire. Use a funnel or spout
when pouring fuel.
e. Avoid over filling the fuel tank. Allow % inch
V for expansion. Tighten Fuel Cap securely. Ftg-
ure 14.
f. Wipe up ail fuel spills. Wipe off any fuel spilled
on the saw. Completely dry the saw before
using.
g. Move at least 10 feet (3 meters) away from'
fuel and fueling site before starting the en-
gine.
