rial.

following points are observed:
–
Round file matches the chain pitch.
–
File from the inside to the outside of the cut‐
ter.
–
Hold the file at right angle to the guide bar.
–
Maintain a filing angle of 30°.

that they are level with the STIHL filing gauge
and parallel to the service mark. The STIHL fil‐
ing gauge must match the chain pitch.
