12.9 Wear limits of the blades

The blades must be reversed or
replaced before reaching the
specified wear limits (A, B, C, D).
STIHL recommends STIHL
specialist dealers.
The specified values should be
measured at several points (two or
three recommended) along the
cutting edge on all the blades.
Use the smallest value for a blade.
We recommend that you always
reverse or replace all the blades at
the same time.

The blade (3) must be reversed or
replaced if the distance measured
is less than the minimum
distance (C).
