Guide Bar Maintenance
When the guide bar shows signs of wear, turn it over on the
saw to distribute the wear for maximum bar life. Feathering or
burring of the bar rails is a normal process of bar wear. You
should smooth such faults with a file as soon as they occur.
Replace a bar with any of the following faults:
• wear inside the bar rails permitting the chain to
lay over sideways
• bent guide bar
• cracked or broken rails
• spread rails
Turn the saw over, check the underside of the guide bar, and
make sure that the lubrication holes and chain groove are free
from impurities.
