ON/STOP SWITCH
The ON/STOP SWITCH is used to stop the
engine.
THROTTLE TRIGGER
The THROTTLE TRIGGER controls engine
speed.
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 or for refueled starting. 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 30 minutes of operation. You should
check your chain tension frequently. See
CHAIN TENSION in the ASSEMBLY sec-
tion.
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
ratio of 40:1. Poulan/WEED EATER brand
synthetic oil is recommended. Mix gasoline
and oil at a ratio of 40:1. A 40:1 ratio is obtained
by mixing 3.2 ounces of oil with 1 gallon of
unleaded 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 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 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 Poulan or
Poulan PRO 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.
