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.
After each use, ensure ON/STOP switch is
inthe 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 berand chain from
SaW.
• Clean the oilholes and bar groove aftereach
