6.1.4 Incorrect Sharpening
Angles
There are a number of reasons for

incorrect sharpening angles:

– wrong file diameter
– wrong file holder
– incorrect filing
– incorrect adjustment of
sharpener or filing tool
– incorrectly dressed grinding
wheels
Only the primary effects are listed
under "Condition". Secondary
effects (damage) are found under
"Cutters and Tie Straps".
If incorrect sharpening angles occur
on only one side of the chain (along
its whole length), the chain will
wander in the cut. The same
happens if the chain is dull on one
side.
