CARBURETOR ADJUSTMENT
WARNING:
The chain will be moving
during most of this procedure. Wear your pro-
tective equipment and observe all safety pre-
cautions. The chain must not move at idle
speed.
The carburetor has been carefully set at the
factory. Adjustments may be necessary if
you notice any of the following conditions:
S
Chain moves at idle. See IDLE SPEED- T
adjusting procedure.
S
Saw will not idle. See IDLE SPEED- T ad-
justing procedure.
Idle Speed- T
Allow engine to idle. If the chain moves, idle is
too fast. If the engine stalls, idle is too slow. Ad-
just speed until engine runs without chain
movement (idle too fast) or stalling (idle too
slow). The idle speed screw is located in the
area above the primer bulb and is labeled T.
S
Turn idle screw (T) clockwise to increase
engine speed.
S
Turn idle screw (T) counterclockwise to
decrease engine speed.
If you require further assistance or are unsure
about performing this procedure, contact your
authorized service dealer or call our customer
assistance help line at 1- 800- 554- 6723.
COOLING SYSTEM
To keep the working temperature as low as
possible the machine is equipped with a
cooling system.
The cooling system consists of:
S
Air intake on the starter
S
Air guide plate
S
Fins on the flywheel
S
Cooling fins on the cylinder
S
Cylinder cover (directs cold air over the
cylinder)
Clean the cooling system with a brush after
each use, more often in demanding condi-
tions. A dirty or blocked cooling system re-
sults in the machine overheating which
causes damage to the piston and cylinder.
STORAGE
WARNING:
Perform the following
steps after each use:
S
Allow the engine to cool, and secure the
unit before storing or transporting.
S
Store chain saw and fuel in a well venti-
lated area where fuel vapors cannot reach
sparks or open flames from water heaters,
electric motors or switches, furnaces, etc.
S
Store chain saw with all guards in place
and position chain saw so that any sharp
object cannot accidentally cause injury.
S
Store chain saw well out of the reach of
children.
SEASONAL STORAGE
Prepare your unit for storage at the end of the
season or if it will not be used for 30 days or
more. If your chain saw is to be stored for a
period of time:
S
Clean saw thoroughly before storage.
S
Store in a clean dry area.
S
Lightly oil external metal surfaces and
guide bar.
S
Oil the chain and wrap it in heavy paper or
cloth.
FUEL SYSTEM
Under FUELING ENGINE in the OPERA-
TION section of this manual, see message
labeled
IMPORTANT
regarding the use of
gasohol in your chain saw. Fuel stabilizer is
an acceptable alternative in minimizing the
formation of fuel gum deposits during stor-
age. Add stabilizer to the gasoline in the fuel
tank or fuel storage container. Follow the mix
instructions found on stabilizer containers.
Run engine at least 5 minutes after adding
stabilizer.
Poulan/WEED
EATER
40:1,
2-cycle engine oil (air cooled) is blended with
fuel stabilizer. If you do not use this oil, you
can add a fuel stabilizer to your fuel tank.
HELPFUL TIP
During storage of your gas/
oil mixture, the oil will sepa-
rate from the gas.
We recommend that you
shake the gas can weekly
to insure proper blending of
the gas and oil.
ENGINE
S
Remove spark plug and pour 1 teaspoon
of 40:1, 2-cycle engine oil (air cooled)
through the spark plug opening. Slowly
pull the starter rope 8 to 10 times to distrib-
ute oil.
S
Replace spark plug with new one of rec-
ommended type and heat range.
S
Clean air filter.
S
Check entire unit for loose screws, nuts,
and bolts. Replace any damaged, broken,
or worn parts.
