CARBURETOR
ADJUSTMENTS
Your carburetor
is equipped
with limiter
caps.
Carburetor
adjustment is a compli-
cated task. We recommend
that you take
your unit to an authorized service
dealer.
Damage will occur if you turn the needles be-
yond the limiter stops.
BAR MAINTENANCE
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 your bar. A worn bar will dam-
age your chain and make cutting difficult.
Affer 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.
