A special holder with a 4 mm round le should be used for sharpening. Regular round les are not suitable for
sharpening. The sharpening should only be done with the le moving forward (in the direction of the arrow).
If the le is moved backwards, the pressure on the tool should be reduced (g. 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 le as shown in the illustration. The le holder makes it easier to guide the le 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 le diameter) (g. 34).

Even a slight excess of the depth gauge tooth should be ground down with a special at le. 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 (g. 35).
