Guide Bar Failures
Over time, guide rails may become worn and uneven. These
damaged rails will cause your saw chain to cut unevenly
through the timber. As the saw chain travels through the guide
rails the cutters will pull the saw chain in the direction of its
cut. When a cutter is angled to the left it will pull the chain to
the left and when angled to the right a cutter will pull the saw
chain to the right.
A saw chain that is sharpened and cutting properly will
balance out it’s natural pull. Saw chains that are improperly
sharpened or are running on uneven rails will have uneven
pull from the saw chain cutters and will cause more wear on
the rails and the bar groove.
Pressure on the guide rails will cause the wire edge rail effect.
The wear on the rails, if not filed down, will result in possible
chipping or breakage.
