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 Sharpen frequently, take away as
little metal as possible – two or three
strokes of the file are usually
enough.
N Resharpen the teeth (1) uniformly –
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
N After resharpening about 5 times,
check the cutting attachment for
out-of-balance on a STIHL balancer
– see “Special Accessories” – or
have it checked by a dealer and re-
balanced as necessary – STIHL
recommends a STIHL servicing
dealer.
Placing power tool on the ground
N Shut off the engine.
N Lay your power tool on its back so
that the cutting attachment
mounting face is pointing up.

of wear before replacing the nylon line.

head.
