Furthermore, the angles must be the
same on all cutters. If angles are
uneven: Chain will run roughly, not in a
straight line, wear quickly and finally
break.
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 Super chain. The
correct filing angle is marked on the file
holder.
* see “Guide to Using this Manual”
For checking angles
STlHL filing gauge* (see table).
A universal tool for checking the filing
and side plate angles, depth gauge
setting and cutter length. Also cleans the
guide bar groove and oil inlet hole.

File correctly
: If you use a file holder, the FG 1 or
FG 3:
Leave the chain on the bar.
: Clamp the bar in a vise if necessary.
: Lock the chain – push hand guard
forward.
: To rotate the chain – pull hand guard
against handle.
: Sharpen chain frequently, take
away as little metal as possible –
two or three strokes of the file are
usually enough.
: 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.
