Furthermore, the angles must be the
same on all cutters. If angles are uneven
the chain will run roughly, not in a
straight line, wear quickly and break
prematurely.
As these requirements can be met only
after sufficient and constant practice:
: Use a file holder
A file holder must be used for manual
resharpening of saw chain (see table
"Sharpening Tools"). The correct filing
angles are marked on the file holder.

60°
30° 35°
10° 0°
Use a STlHL filing gauge (see table
"Sharpening Tools"). This is a universal
tool for checking the filing and side plate
angles, depth gauge setting and cutter
length. It also cleans the guide bar
groove and oil inlet holes.
File correctly
: If you use an FG 2, HOS or USG
sharpener: Remove the chain from
the bar and sharpen according to
instructions supplied with the tool.
: Sharpen chain frequently; take
away as little metal as possible –
two or three strokes of the file are
usually enough.
: Hold the file horizontally (at right
angle to side of guide bar) and file
according to the angles marked on
the file holder. Rest the file holder on
the top plate and depth gauge.
: Always file from the inside to the
outside of the cutter.
: The file only sharpens on the
forward stroke – lift the file off the
cutter on the backstroke.
: Avoid touching the tie straps and
drive links with the file.
