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 (special accessory) 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 and cutter length. It 
also cleans the guide bar groove and oil 
inlet holes.
File correctly
: Select sharpening tools according 
to chain pitch.
: Clamp the bar in a vise if necessary.
: Lock the chain – push hand guard 
forward.
: To rotate the chain, pull the hand 
guard against the front handle to 
disengage the chain brake. On 
models with QuickStop Super, also 
press down the throttle trigger 
interlock lever.
: 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.
