FUELING ENGINE
This engine is certified to operate on unleaded
gasoline. Before operation, gasoline must be
mixed with a good quality 2-cycle air.ceoled
engine oil. We recommend Poolan or Poulan
Pro® brand oil, ffyou do not use this oil, use a
good quality 2-cycle air-ceoied 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. Included with this saw is
a 3.2 ounce container of Poolan/Weed Eater
brand oil. Pour the entire contents of this
container into 1 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 lubrica-
tion, Lubrication is provided by the automatic
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 discolor-
ation 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 #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 Poolan® 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 alcehoi-bleeded
fuels (called gasohoi or using ethanol or meth-
anol) can attract moisture which leads to sepa-
ration and formation of acids during storage,
Acidic gas can damage the fuel system of an
engine while in storage. To avoid engine prob-
lems, 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.
