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.
FUELING & LUBRICATION
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. In-
cluded with this saw is a 3.2 ounce container of
Poulan/WEED EATER brand synthetic oil.
Pour the entire contents of this container into 1
gallon 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.
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
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-
tional information.
STARTING
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.

Use only 15″ -- 18″ (38 -- 45 cm) of
rope per pull.
Hold saw firmly while pulling starter rope.
IMPORTANT POINTS TO REMEMBER
When pulling the starter rope, do not use the
full extent of the rope as this can cause the
rope to break. Do not let starter rope snap
back. Hold the handle and let the rope re-
wind slowly.
For cold weather starting, start the unit at
FULL CHOKE; allow the engine to warm up
before squeezing the throttle trigger.
NOTE: Do not attempt to cut material with
the choke/fast idle lever in the FULL CHOKE
position.
