When cutting performance and behavior 
begin to deteriorate, i.e. blades 
frequently snag on branches: 
Resharpen the cutting blades.
It is best to have the cutting blades 
resharpened by a dealer on a workshop 
sharpener. STIHL recommends a STIHL 
servicing dealer.
It is also possible to use a flat crosscut 
sharpening file. Hold the sharpening file 
at the prescribed angle (see 
"Specifications").
N Always file towards the cutting 
edge.
N The file only sharpens on the 
forward stroke – lift it off the blade 
on the backstroke.
N Use a whetstone to remove burr 
from cutting edge.
N Remove as little material as 
possible.
N After sharpening, clean away filing 
or grinding dust and then spray the 
cutting blades with STIHL resin 
solvent.
Sharpening Instructions
Do not operate your machine with 
dull or damaged cutting blades. 
This may cause overload and will 
give unsatisfactory cutting results.
