THROTTLE LOCK---OUT
The THROTTLE LOCK--OUT must be
pressed before you can squeeze the throttle
trigger. This feature prevents you from acci-
dentally squeezing the trigger.
CHOKE/FAST IDLE LEVER
The choke and fast idle speed are set by pull-
ing the CHOKE/FAST IDLE LEVER out fully
for cold starting or after refueling. The choke
provides additional fuel to the engine during
cold starting.
CHAIN BRAKE
The CHAIN BRAKE is a device designed to
stop the chain if kickback occurs. The chain
brake activates automatically in the event of
kickback. The chain brake activates manu-
ally if the front hand guard is pushed forward.
The chain brake is disengaged by pulling the
front hand guard back toward the front han-
dle as far as possible.
CHAIN TENSION
It is normal for a new chain to stretch during first
15 minutes of operation. You should check
your chain tension frequently. See CHAIN
TENSION in the ASSEMBLY section.
WARNING:
If the saw is operated
with a loose chain, the chain could jump off
the guide bar and result in serious injury to
the operator and/or damage the chain mak-
ing it unusable.
BEFORE STARTING ENGINE
WARNING:
Muffler is very hot dur-
ing and after use. Do not touch the muffler or
allow combustible material such as dry
grass or fuel to do so.
WARNING:
Be sure to read the fuel
handling information in the safety rules sec-
tion of this manual before you begin. If you do
not understand the fuel handling information
do not attempt to fuel your unit. Seek help
from someone that does understand the in-
formation or call the customer assistance
help line at 1-800-554-6723.
FUELING ENGINE
WARNING:
Remove fuel cap slow-
ly when refueling.
HELPFUL TIP
To obtain the correct oil mix
ratio, pour 3.2 ounces 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
ratio of 40:1. Poulan/WEED EATER brand
synthetic oil is recommended. A 40:1 ratio is
obtained by mixing 3.2 fluid ounces (95 ml) of
oil with 1 gallon (4 liters) of unleaded gasoline.
Included with this saw is a 3.2 ounce (95 ml)
container of Poulan/WEED EATER brand
synthetic oil. Pour the entire contents of this
container into 1 gallon (4 liters) of gasoline to
achieve the proper fuel mixture. DO NOT USE
automotive or marine 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.
CAUTION: Never use straight gasoline in
your unit. This will cause permanent engine
damage and void the limited warranty.
FUEL REQUIREMENTS
This engine requires the use of minimum 87
octane [R+M]/2 clean gasoline.
IMPORTANT
Use of alcohol blended fuels (called gasohol or
using ethanol or methanol) can cause major
engine performance and durability problems.
WARNING:
Alternative fuels (not
gasoline) such as E--15 (15% alcohol), E--20
(20% alcohol), E--85 (85% alcohol) are NOT
classified as gasoline and are NOT approved
for use in 2--stroke gasoline engines. Use of al-
ternative fuels will cause problems such as: im-
proper clutch engagements, overheating, va-
por lock, power loss, lubrication deficiency,
deterioration of fuel lines, gaskets and internal
carburetor components, etc. Alternative fuels
cause high moisture absorption into the fuel/oil
mixture leading to oil and fuel separation.
BAR AND CHAIN LUBRICATION
The bar and chain require continuous lubrica-
tion. Lubrication is provided by the automatic
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 discolor-
ation 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.
S
Never use waste oil for bar and chain lubri-
cation.
S Always stop the engine before removing
the oil cap.
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.
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
