Guide Bar Failures
Improper depth gauge settings will cause damage to your
guide rails at any location of the guide bar. The nose of a
sprocket nose guide bar, though, is susceptible to additional
damage and wear. When cutting with a saw chain that has too
loose of tension additional material wear will occur.
When a saw chain comes free during cutting, due to loose
tension, the bar nose may become twisted. A twisted bar nose
will not allow the sprocket to turn freely and will result in a
replacement guide bar being needed do to excessive damage.
