The blades must be resharpened if 
cutting performance and behavior begin 
to deteriorate (i.e. if blades frequently 
snag on branches).
It is best to have the cutting blades 
resharpened by your STIHL dealer on a 
workshop sharpener.
Do not operate your unit with dull or 
damaged blades – this may cause 
overload and will give unsatisfactory 
cutting results.
