are not the same.
The chain is not fixed during
sharpening.
The wrong cutter is sharpened.

the 2 different directions.
Wrong parts of the cutters are
sharpened.
The cutters are not correctly
sharpened.

position when the machine was
started.

incorrect.
The grinding speed is set too high
and the metal is overheated.
