THROTTLE TRIGGER
The THROTTLE TRIGGER controls engine
speed.
THROTTLE LOCKOUT
The THROTTLE LOCKOUT must be pressed
before you can squeeze the throttle trigger.
This feature prevents you from accidentally
squeezing the trigger.
CHOKE/FAST IDLE LEVER
The choke and fast idle are set by pulling the
CHOKE/FAST IDLE LEVER out fully for cold
or refueled starting. The choke provides addi-
tional fuel to the engine during cold starting.
PRIMER BULB
The PRIMER BULB circulates fuel to the
carburetor 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
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 under the SERVICE AND AD-
JUSTMENTS 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
WARNING: Remove fuel cap slow-
ly when refueling.
FUELING ENGINE
This engine is certified to operate on
unleaded gasoline. Before operation,
gasoline must be mixed with a good quality
2-cycle air-cooled engine oil. We
recommend Poulan or Poulan Pro R brand
oil. If you do not use this oil, use a good
quality 2-cycle air-cooled oil designed to be
mixed at a ratio of 40:1 (A 40:1 ratio is
obtained by mixing 3.2 onces of oil with 1
gallon of unleaded gasoline). DO NOT USE
automotive or boat 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 or Poulan Pro R bar and
chain oil is recommended to protect your unit
against excessive wear from heat and
friction. Poulan or Poulan Pro R oil resists
high temperature thinning. If Poulan or
Poulan Pro R 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
