FUELING & LUBRICATION
FUELING ENGINE
WARNING: Remove fuel cap slow-
ly when refueling.
HELPFUL TIP
To obtain the correct oil mix
ratio, pour 3.2 ounces of
2--cycle synthetic oil into
one gallon of fresh gas.
This engine is certified to operate on
unleaded gasoline. Before operation,
gasoline must be m ixed 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
mixing3.2ounces (95ml)ofoi lwith1 gallon(4
liters) ofunleaded gasoline. Inc luded with this
saw is a 3.2 ounce container of Poulan/WEED
EA TER brand synthetic oil. Pour the entire
contents of this container into 1 gallon of
gasoline to achieve the proper fuel mixture.
DO NOT USE automotive or boatoil. These
oils will cause enginedamage. Whenmixing
fuel follow the instructions printed on the
container. Always read andfollow 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 o f oil will quickly ruin the ba r and
chain. To o little oil will cause overheating
shown by smoke coming from thechain and/
or discoloration of the bar.
In f reezing weather oil will thicken, making it
necessary to thin bar and chain oil with a
small amount ( 5 to 10%) of #1 Diesel Fuel or
kerosene. Bar and chain oil must be free
flowingforthe oilsystemto pump enough oil
for adequate lubrication.
Genuine Poulan or Poulan PRO bar and
chain oil is recommended toprotect your unit
against e xcessive w ear from heat and
friction. Poulan or Poulan PRO oil resists
high temperature thinning. If Poulan or
Poulan P RO bar and chain oil is not
available, use a good grade SAE 30 oil.
S Never use waste oilfor bar and chainlubri-
cation.
S 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 t o CAR-
BURETOR ADJUSTMENT within this
