CARBURETOR ADJUSTMENT

WARNING:
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 ad-
justing procedure.
S Saw will not idle. See IDLE SPEED-T adjust-
ing 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 speed screw (T) clockwise to in-
crease engine speed.
S Turn idle speed screw (T) counterclockwise
to decrease engine speed.
S Store in a dry area out of the reach of chil-
dren.
S Ensure the machine is cleaned and that a
complete service is carried out before long-
term storage.
S The guide bar and chain must always be cov-
ered with a scabbard when the machine is
being transported or in storage in order to
prevent accident contact with the sharp
chain. Even a non-moving chain can cause
serious cuts to yourself or persons you bump
into 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.
The chain will be moving
