The specified angles A and B are
obtained automatically if the
recommended files or sharpening tools
and correct settings are used.
The angles must be the same on all
cutters. If the 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:
N Use a file holder
A file holder must be used for manual
resharpening (see table "Sharpening
Tools"). The correct filing angles are
marked on the file holder.

Use a STlHL filing gauge (special
accessory, see table "Sharpening
Tools"). This is a universal tool for
checking the filing and side plate angles,
depth gauge setting, cutter length and
groove depth. It also cleans the guide
bar groove and oil inlet holes.
File correctly
N Select sharpening tools according
to chain pitch.
N Clamp the bar in a vise if necessary.
N Lock the chain – push hand guard
forward.
N To rotate the chain – pull hand
guard against handle to disengage
the chain brake On models with
Quickstop Plus, also press down
the throttle trigger lockout lever.
N
Sharpen the chain frequently, take
away as little metal as possible –
two or three strokes of the file are
usually enough.
N Hold the file horizontally (at a right
angle to the side of the guide bar)
and file according to the angles
marked on the file holder. Rest the
file holder on the top plate and depth
gauge.
N Always file from the inside to the
outside of the cutter.
N The file only sharpens on the
forward stroke – lift the file off the
cutter on the backstroke.
N Avoid touching the tie straps and
drive links with the file.
N
Rotate the file at regular intervals
while filing to avoid one-sided wear.
N Use a piece of hardwood to remove
burrs from the cutting edge.
N Check angles with the filing gauge.
All cutters must be the same length.
