N Use a sharpening file (see "Special 
Accessories") to sharpen dull 
cutting attachments. In case of 
more serious wear or nicks: 
Resharpen with a grinder or have 
the work done by a dealer – STIHL 
recommends a STIHL servicing 
dealer.
N Resharpen frequently, take away as 
little material as possible: two or 
three strokes of the file are usually 
enough.
N Resharpen the cutters (1) uniformly 
– do not alter the contour or the 
parent blade (2) in any way.
See cutting attachment packaging for 
additional sharpening instructions.
Balancing
N After resharpening about 5 times, 
check the cutting tool for out-of-
balance on a STIHL balancer 
(special accessory) or have it 
checked by a dealer and re-
balanced as necessary – STIHL 
recommends a STIHL servicing 
dealer.

N If the engine is down on power,

STIHL recommends that you have

exclusively by an authorized STIHL 
servicing dealer.
