Starting A Cold Engine - Poulan Pro 221 Instruction Manual

FUELING & LUBRICATION
WARNING:
Remove fuel cap slow-
ly when refueling.
FUELING ENGINE
This engine is certified to operate on
unleaded gasoline. Before
gasoline must be mixed with a good quality
2-cycle air-cooled engine
recommend Poulan PROR 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 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 #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 or Poulan PROR bar and
chain oil is recommended to protect your unit
against excessive wear from heat and
friction. Poulan or Poulan PROR oil resists
high temperature thinning.
Poulan PROR bar and chain oil is not
available, use a good grade SAE 30 oil.
S Never use waste oil for bar and chain lubri-
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.
