FUELING ENGINE
A_il_ W ARNING: Remove fuelcapsIow-
FUELING ENGINE
This engine is certified to operate on
untended gasoline. Before operation,
gasoline must be mixed with a good quality
synthetic 2-cycle athcooled engine oil
designed to be mixed at a ratio of 40:1.
Poulan/WEED EATER brand synthetic oil is
recommended. Mix gasoline and oil at a ratio
of 40:f A40:1 ratioisobtainedbymixing3.2
ounces of oil with 1 gaIIon of unteeded
gasoline. Included with this saw is a 3.2
ounce container of oil. Pour the entire
contents of this container into 1 gallon of
gasoline to achieve the proper fuel mixture.
DO NOT USE automotive oil or boat oil. These
oils will 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 lubri-
cation. Lubrication Js 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 oJi will cause overheating
shown by smoke coming from the chain and/
or discoloration of the bar.
in freezing weather oil wil} thicken, making it
necessary to thin bar and chain oil with a
smalt amount (5 to 10%) of #f Diesel FueI or
kerosene. Bar and chain oil must be free
flowing for the oil system to pump enough oil
for adequate lubrication.
Genuine Roulan or Poulan PRO bar and
chain oil is recommended to protect your unit
against excessive wear from heat and
friction. Poulan or Poulan PRO oil resists
high temperature thinning. If PouIan or
Poufan PRO bar and chain oil is not
available, use a good grade SAE 30 oil.
• Never use waste oil for bar and chain tubd-
cation.
• Always stop the engine before remowng
the oit cap.
IMPORTANT
Experience indicates that alcohoFblended
fuels (ca}led 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 fue} lines and
carburetor are empty Use fresh fuel next
season. See STORAGE section for addi-
tional information.
CHAIN BRAKE
Ensure chain brake is disengaged by pulling
the front hand guard back toward the front han-
dle as far as possible. The chain brake must be
disengaged before cutting with the saw.
_I_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.
To start the engine hold the saw firmly on the
ground as illustrated. Make sure the chain is
free to turn w_thout contacting any object
