FUELING ENGINE
This engine is certified to operate on
unleaded gasoline. Before operation,
gasoline must be mixed with a good quality
synthetic 2-cycle air-cooled engine oil
designed to be mixed at a ratio of 40:1.
PoulanANeed Eater brand synthetic oil is
recommended. Mix gasoline and oil at a ratio
of 40:1. A 40:1 ratio is obtained by mixing 3.2
ounces of oil with 1 gallon of unleaded
gasoline. Included with this saw is a 3.2
ounce container of oil. Pour the entire
contents of this container into t gallon of
gasoline to achieve the proper fuel mixture.
DO NOT USE automotive oil or boat oil. These
oils will cause engine damage. When mixing
fuel, follow instnJctions printed on container.
Once oil is added to gasoline, shake container
momentarily to assure that the fuel is
thoroughly mixed. Always read and follow the
safety nJles relating to fuel before fueling your
unit.
BAR AND CHAIN LUBRICATION
The bar and chain require continuous lubri-
cation. Lubrication is provided by the auto-
matic oiler system when the oil tank is kept
filled. Lack of oil will quickly ruin the bar and
chain. Too little oil will cause overheating
shown by smoke coming from the chain and/
or discoloration of the bar.
In freezing weather oil will thicken, making it
necessary to thin bar and chain oil with a
small amount (5 to t 0%) of #1 Diesel Fuel or
kerosene. Bar and chain oil must be free
flowing for the oil system to pump enough oil
for adequate lubrication.
Genuine Poulan® bar and chain oil is
recommended to protect your unit against
excessive wear from heat and friction.
Poulan® oil resists high temperature
thinning. If Poulan ® bar and chain oil is not
available, use a good grade SAE 30 oil.
• Never use waste oil for bar and chain lubri-
cation.
• Always stop the engine before removing
the oil cap.
IMPORTANT
Experience indicates that alcobel-blenbed
fuels called gasohol or using ethanol or
methanol) can attract mo sture wh ch leads
to separation and formation of acids during
storage. Acidic gas can damage the fuel
system of an engine while in storage. To
avoid engine problems, the fuel system
should be emptied before storage for 30
days or longer. Drain the gas tank, start the
engine and let it run until the fuel lines and
carburetor are empty. Use fresh fuel next
season. See STORAGE section for addi-
tional information.
