Sharpening Metal Cutting
Blades
Use a sharpening file (see "Special
N
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.
Sharpen frequently, take away as
N
little metal as possible – two or three
strokes of the file are usually
enough.

Resharpen the teeth (1) uniformly –
N
do not alter the contour of the parent
blade (2) in any way.
See cutting attachment packaging for
additional sharpening instructions. Keep
the packaging for future reference.
Balancing
After resharpening about 5 times,
N
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.
