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.
Poulan/Weed Eater brand synthetic oil is
recommended. A 40:1 ratio is obtained by
mixing 3.2 ounces (95 ml) ofoil with 1 gallon (4
Iiters) of unleaded gasoline. Indudedwiththis
saw is a 3.2 ounce container of Poulan/Weed
Eater brand synthetic oil. Pour the entire
contents of this container into I gallon of
gasoline to achieve the proper fuel mixture.
DO NOT USE automotive or boat oil. These
oils will cause engine damage. When mixing
fuel follow the instructions printed on the
container. Always read and follow the safety
rules listed under HANDLE FUEL WITH
CAUTION.
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 10%) of #I Diesel Fuel or
kerosene. Bar and chain oil must be free
flowing for the oil system to pump enough oil
for adequate Iublication.
Genuine Peutan®) bar and chain oil is
recommended to protect your unit against
excessive wear from heat and fiiction.
Poulan(,; oil resists high temperature
thinning. If Poulan(D 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 alcohol-blended
fuels called gasohol or using ethanol or
methanol can attract moisture which 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.

move when the engine runs at idle speed. If
the chain moves at idle speed refer to CAR-
BURETOR ADJUSTMENT within this
