Saw Chain Maintenance Errors
Improper maintenance of saw chain will cause failures in your
timber cutting and your saw chain. Most saw chains are not
properly maintained and therefore are not used to their
full cutting efficiency.
There are several common errors when sharpening your
saw chain that will cause failure in your saw chain and
shorten your saw chain’s life.
One of the most common errors occurs when
the leading edge is essentially filed away. This creates
what is commonly known as a BACKSLOPED cutter.
A backslope cutter is caused by filing with a larger file
size, or filing too high up on the cutter’s leading edge.
Backslope cutters, without a leading edge, will not
be able to catch the cutting surface. The natural user
reaction when this occurs is to apply more pressure
to your chain saw. Applying unnecessary pressure will
cause increased wear and possible breakage.
