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.
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.
