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
in the STOP position, then clean ati 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.
