CARBURETOR ADJUSTMENT WARNING! The chain will be moving during most of this procedure. Wear your protective equipment and observe all safety precautions. The chain must not move at idle speed. Indications for idle speed adjustment The carburetor has been carefully set at the factory. Adjustments may be necessary if you notice any of the following conditions: • The chain moves at idle. See IDLE SPEED-T ADJUSTMENT procedure. • The saw will not idle. See IDLE SPEED-T ADJUSTMENT procedure. Idle speed-T adjustment Allow the engine to idle. If the chain moves, the idle is too fast. If the engine stalls, the idle is too slow. Adjust the speed until the 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 (air purge) bulb and is labeled "T". Turn the idle speed screw (T) clockwise to increase the engine speed. Turn the idle speed screw (T) counterclockwise to decrease the engine speed. STORAGE WARNING! Stop the engine and allow it to cool. Secure the unit before storing or transporting it in a vehicle. Store the unit and fuel in an area where fuel vapors cannot reach sparks or open flames from water heaters, electric motors, switches, furnaces, etc. WARNING ! Store the unit with all guards in place. Position so that any sharp object cannot accidentally cause injury to passersby. Store the unit out of reach of children. • Before storing, drain all fuel from the unit. Start the engine and allow it to run until it runs completely out of fuel. • Clean the unit before storing. Pay particular attention to the air intake area, keeping it free of debris. Use a mild detergent and sponge to clean the plastic surfaces. • Ensure the machine is cleaned and that a complete service is carried out before long-term storage. • The guide bar and chain should be covered with a scabbard when the machine is being transported or in storage in order to prevent accidental contact with the sharp chain. Even a non-moving chain can cause serious cuts to yourself or others that make contact with an exposed chain. CAUTION: It is important to prevent gum deposits from forming in essential fuel system parts such as the carburetor, fuel filter, fuel hose, or fuel tank during storage. Alcohol blended fuels (called gasohol) or using ethanol or methanol can attract moisture which leads to fuel mixture separation and formation of acids during storage. Acidic gas can damage the engine. 15

CARBURETOR ADJUSTMENT
WARNING! The chain will be moving during
most of this procedure. Wear your
protective equipment and observe all safety
precautions. The chain must not move at
idle speed.
Indications for idle speed adjustment
The carburetor has been carefully set at the
factory. Adjustments may be necessary if you
notice any of the following conditions:
•
The chain moves at idle. See IDLE SPEED-T
ADJUSTMENT procedure.
•
The saw will not idle. See IDLE SPEED-T
ADJUSTMENT procedure.
Idle speed-T adjustment
Allow the engine to idle. If the chain moves, the
idle is too fast. If the engine stalls, the idle is too
slow.
Adjust the speed until the 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 (air purge) bulb and is labeled “T”.
Turn the idle speed screw (T) clockwise to
increase the engine speed.
Turn the idle speed screw (T) counterclockwise to
decrease the engine speed.
STORAGE
WARNING! Stop the engine and allow it to
cool. Secure the unit before storing or
transporting it in a vehicle. Store the unit
and fuel in an area where fuel vapors cannot
reach sparks or open flames from water
heaters, electric motors, switches, furnaces,
etc.
WARNING ! Store the unit with all guards in
place. Position so that any sharp object
cannot accidentally cause injury to
passersby. Store the unit out of reach of
children.
•
Before storing, drain all fuel from the unit. Start
the engine and allow it to run until it runs
completely out of fuel.
•
Clean the unit before storing. Pay particular
attention to the air intake area, keeping it free of
debris. Use a mild detergent and sponge to
clean the plastic surfaces.
•
Ensure the machine is cleaned and that a
complete service is carried out before long-term
storage.
•
The guide bar and chain should be covered with
a scabbard when the machine is being
transported or in storage in order to prevent
accidental contact with the sharp chain. Even a
non-moving chain can cause serious cuts to
yourself or others that make contact with an
exposed chain.
CAUTION: It is important to prevent gum
deposits from forming in essential fuel system
parts such as the carburetor, fuel filter, fuel
hose, or fuel tank during storage. Alcohol
blended fuels (called gasohol) or using ethanol
or methanol can attract moisture which leads to
fuel mixture separation and formation of acids
during storage. Acidic gas can damage the
engine.
