Risk of injury:
Always wear gloves.
Before attaching the
blade set, visually check
that the blade disc and all
shredding blades are OK and have
no notches, cracks or pieces
chipped out.
Clean the blade mounting on the
machine, the blade disc and the
shredding blade before attaching
the blade set.
The blade disc including the
chipping blade and the three wing
blades are equipped with a toothed
blade mounting. This prevents
incorrect installation of the entire
cutting unit, as the blades can only
be attached to the blade mounting
when in the correct position.

The numbers (3) on the inside of
the wing blades refer to their
installation sequence.
The blades must be reversed or
replaced before the specified wear
limits are reached. STIHL
recommends STIHL specialist
dealers.
