A special holder with a 4 mm round file should be used for sharpening. Regular round files are not suitable for
sharpening. The sharpening should only be done with the file moving forward (in the direction of the arrow).
If the file is moved backwards, the pressure on the tool should be reduced (fig. 33).

First the shortest saw tooth is sharpened. Its length is the target length for sharpening all other teeth of the
saw chain. Guide the file as shown in the illustration. The file holder makes it easier to guide the file during
sharpening and has a marking for the correct 30° sharpening angle (align the marking with the direction
of the saw chain). It limits the penetration depth (4/5 of the file diameter) (fig. 34).

Even a slight excess of the depth gauge tooth should be ground down with a special flat file. The depth gauge
should be rounded at the front.
At the end of the sharpening process, the height of the depth stop should be checked with a chain gauge (fig. 35).
