: Use flat file 0814 212 3310 to
sharpen dull cutting blades. In case
of more serious wear or nicks:
Resharpen with grinder or have
work done by a STIHL dealer.
: Resharpen frequently, take away as
little material as possible - two or
three strokes of the file are usually
enough.
To avoid out-of-balance:
: Resharpen the cutters (1) uniformly
- do not alter the contour or the
parent blade (2) in any way.
: After resharpening about 5 times,
have blade checked on STIHL
balancer 5910 850 2600 and
rebalanced as necessary.
