CARBURETOR
ADJUSTMENT
_WARNING:
The chain will be mov-
ing 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:
• Chain moves at idle. See IDLE SPEED-T
adjusting
procedure.
• 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.
Adjust 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.
• Turn idle speed screw (T) clockwise to in-
crease engine speed.
• Turn idle speed screw (T) counterclock-
wise to decrease engine speed.
If you require further assistance or are unsure
aboL_ performing this procedure, contact your
aL_horized
service
dealer
or
call

if your saw cuts to one side, has to be forced
through the cut, or been run with an improper
amount of bar lubrication
it may be neces-
sary to service you r bar. A worn bar will dam-
age your chain and make cutting difficult.
After each use, ensure ON/STOP
switch is
in the STOP position, then clean all sawdust
from the guide bar and sprocket hole.
To maintain guide bar:
• Move ON/STOP switch to the STOP posi-
tion.
• Loosen and remove chain brake nuts and
chain brake.
Remove bar and chain from
saw.
• Clean the oil holes and bar groove after
each 5 hours of operation.
