FUELING
ENGINE
This
engine
is
certified
to
operate
on
unleaded
gasolh_e.
Before
operation,
gasolh_e 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.
Mix gasoiine and oil at a ratio
of 40:1. A 40:t ratio is obtained by mixh_g 3.2
ounces
of oil with
1 gallon
of unleaded
gasoline,
Included
with this saw is a 3.2
ounce
container
of oil.
Pour
the
entire
contents
of this container
into 1 gallon
of
gasolh_e to achieve
the proper fuel mixture.
DO NOT USE automotive oil or boat oil. These
oils wifl cause engine damage. When mixing
fuel, follow instructions printed on container.
Once oil is added to gasoline, shake container
momentarily
to
assure
that
the
fuel
is
thoroughly mixed. Always read and follow the
safety rules relating to fuel before fueling your
unit.
BAR AND
CHAIN
LUBRICATION
The bar and chain require continuous
tubri-
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_;
bar
and
chain
oil
is
recommended
to protect
your
unit against
excessive
wear
from
heat
and
friction.
Poulan_;
oil resists
high temperature
thinning.
If Poulan_;
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
gasoho]
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.
