18.1 Sharpening and Balancing the Blade
Correctly sharpening and balancing the blade requires a lot 
of practice.
STIHL files, filing aids and sharpeners help you sharpen the 
blade correctly.
STIHL recommends you have the blade resharpened and 
balanced by a STIHL servicing dealer.
► Switch off the mower, remove the activation key and 
battery.
► Stand the mower on end.
► Remove the blade.
► Use a STIHL flat crosscut file to sharpen the cutting edge 
(1). The file only sharpens on the forward stroke. Maintain 
the specified sharpening angle, @ 21.2.
► Turn the blade (2) over.
► Sharpen the other cutting edge (1).
► Mount the blade.
► If you have any queries: Contact your STIHL servicing 
dealer for assistance.

the battery.
