HELPFUL TIP
To obtain thecorrect oil mix
ratio, pour 3.2 ounc es of
2--cycle synthetic oil into
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 EA TER brand syn-
thetic oil is recommended. A 40:1 ratio is
obtained b y mixing 3.2 ounces (9 5 ml) of oil
with 1 gal lon (4 lit er s ) of unleaded gasoline.
Included with this saw is a 3.2 ounce (95 ml)
container of Poulan/WEED EA TER brand syn-
thetic oi l. Pour the entire contents of this con-
tainer in to 1 gallon (4 l iters) of gasoline to
achieve the proper fuel mixture.
DO NOT USE automotive or marine oil.
These oils willcause enginedamage. When
mixing fuel follow the instructions printed on
the container. A lways read and follow the
safety rules listed under HANDLE FUEL
WITH CAUTION.
BAR AND CHAIN LUBRICATION
The ba r and chain require continuous lubri-
cation. Lubrication is provided by the auto-
matic oiler system when the oil tank is k ept
filled. Lack of oil will quickly ruin the bar and
chain. To o little oil will cause overheating
shownby smokecomingfromthe 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%) o f #1 Diesel Fuel or
kerosene. Bar and chain oil must be free
flowing for theoilsystemto pump enoughoil
for adequate lubrication. Genuine Poulan or
Poulan PRO bar andchain o il is recommended
to protect your unit against excessive wear
from heat and friction. Poulan or Poulan PRO
oil resists high temperature thinning.
If Poulanor PoulanPRO bar andchainoilis
not available, use a good grade SAE 30 oil.

cation.
S Always stop the engine before removing
the oil cap.
IMPORTANT
Experience indicates t hat alcohol--blended
fuels (called gasohol or using ethanol or meth-
anol) can attract moisture which leads to sepa-
ration and formation of acids during storage.
Acidic gas can da mag e the fuel system of an
engine while in storage. To avoid engine prob-
lems, the f uel system should be e mptied 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.

the front hand guard back toward the front han-
dle as far as possible. The chainbrake must be
disengaged before cutting with the saw .
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. A void contact with the muf fler. Ahot
muffler can cause serious burns.
To stop t he engine move the ON/STOP
switch to the STOP position.
To start the engine hold the saw firmly on the
