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 are set by pulling the
CHOKE/FAST IDLE LEVER out to the full ex-
tent for cold starting or after refueling. The
choke provides additional fuel to the engine
during cold starting.
PRIMER BULB
The PRIMER BULB circulates fuel to the car-
buretor to provide quicker 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 kick-
back. The chain brake activates manually if the
front hand guard is pushed forward. The chain
brake is disengaged by pulling the front hand
guard back toward the front handle as far as
possible.
CHAIN TENSION
It is normal for a new chain to stretch during the
first 15 minutes of operation. You should check
your chain tension frequently. See CHAIN
TENSION under the ASSEMBLY section.
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.
BEFORE STARTING ENGINE
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 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.
Included with this saw is a 3.2 ounce (95 ml)
container of Poulan/WEED EATER brand syn-
thetic oil. Pour the entire contents of this con-
tainer 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 fol-
low 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 lubri-
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 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.
S
Never use waste oil for bar and chain lubri-
cation.
S Always stop the engine before removing
the oil cap.
IMPORTANT
Experience indicates that 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 damage the fuel system of an
engine while in storage. To avoid engine prob-
lems, 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.
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
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 without contacting any object.
