HELPFUL
TIP
]
\ To obtain the correct oilmix
|
t ratio,
pour 3.2 ounces
of |
2-cycle
synthetic
oil into
I
one gallon of fresh gas.
]
This engine is certified to operate on unleaded
gasoline. Before operation,
gasoline must be
mixed with a good quality synthetic 2-cycle air-
cooled engine oil designed to be mixed at a ra-
tio of 40:1. Poulan/WEED
EATER brand syn-
thetic oil is recommended.
A 40:1 ratio is
obtained by mixing 3,2 ounces
(95 ml) of oil
with 1 gallon (4 liters) of unleaded gasoline.
In-
cluded with this saw is a 3.2 ounce container of
PoulanANEED
EATER
brand synthetic
oil.
Pour the entire contents of this container into 1
gallon of gasoline to achieve
the prober fuel
mixture. DO NOT USE automotive
or marine
oil.
These
oils wilt 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
_ubri-
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 littIe 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 recom-
mended
to protect
your unit against
exces-
sive 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
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-
tionat information.
_=WARNING:
The chain
must not
move when the engine runs at idle speed. If
the chain moves at idle speed refer to CAR-
BURETOR
ADJUSTMENT
within
this
manual, Avoid contact with the muffler. A hot
muffler can cause serious burns.
To stop
the engine
move
the ON/STOP
switch
to the STOP position.
