Use only special saw chain sharpening files. Other files have the wrong shape and cut.
Select file diameter according to chain pitch – see table “Sharpening Tools”.
You must observe certain angles when resharpening the chain cutter.

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:
NUse 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.
For checking angles

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
NSelect sharpening tools according to chain pitch.
NClamp the bar in a vise if necessary.
NLock the chain – push hand guard forward.
NTo rotate the chain – pull hand guard against handle to disengage the chain brake On models with QuickStop Super, also press down the throttle trigger interlock lever.
NSharpen chain frequently, take away as little metal as possible – two or three strokes of the file are usually enough.
