N Use a sharpening file (special

accessory) 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 attachment 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.
