,_.WARNING: The chain wilt 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 fol-
lowing conditions:
• Chain moves at idle. See IDLE
SPEED-T adjusting procedure.
• Saw wilt not idle. See IDLE SPEED-T
adjusting procedure.
Idle Speed-T
Allow engine to idle. If the chain
moves, idle is too fast. If the engine
stalls, idle is too slow. Adjust speed
until engine runs without chain move-
ment (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.
• Turn idle screw (T) clockwise to in-
crease engine speed.
• Turn idle screw (T) counterclockwise
to decrease engine speed.
