FUELING & LUBRICATION
WARNING:
Remove fuel cap slow-
ly when refueling.
FUELING ENGINE
This engine is certified to operate on
unleaded gas oline. Before operation,
gasoline must be mixed with a good quality
2-cycle air-cooled engine oil. We
recommend Poulan or Poulan Pro
R
brand
oil. If you do not use this oil, use a good
quality 2-cycle air-cooled oil designed to be
mixed at a ratio of 40:1 (A 40:1 ratio is
obtained by mixing 3.2 onces of oil with 1
gallon of unleaded gasoline). DO NOT USE
automotive or boat oil. These oils will cause
engine damage. When mixing fuel follow the
instructions printed onthe container. Always
read and follow the safety rules listed under
HANDLE FUEL WITH CAUTION.
BAR AND CHAIN LUBRICATION
The bar and chain r equire 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 bysmokecoming 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 (5to 10%) of #1 Diesel Fuel or
kerosene. Bar and chain oil must be free
flowing for the oil system topump enough oil
for adequate lubrication.
Genuine Poulan or Poulan Pro
R
bar and
chain oil is recommended toprotect yourunit
against excessive wear from heat and
friction. Poulan or Poulan Pro
R
oil resists
high temperature thinning. If Poulan or
Poulan Pro
R
bar and chain oil is not
available, use a good grade SAE 30 oi l.

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
