● The blade width should be measured at
two or three points along the cutting
edge.
Use the smallest value.

The blades must be replaced
before the specified wear limits are
reached. STIHL recommends
STIHL specialist dealers.
The measurement procedure and
the value specified are the same for
all three wing blades.
Asymmetrical wear may occur at
the wing blades due to uneven use
of the cutting edges.
