Replacing the break-pin (BioClip)
The blades are fitted with a break-pin to protect the
BioClip unit and its drive when colliding with
obstacles. A domed, spring friction washer is fitted
to each blade bolt. The washer must always be
replaced with a new washer if the blade bolt is
loosened. Otherwise the break-pin can break
causing the blades to collide.
Only use original spare parts. A set containing a
blade, break-pin and friction washer can be
purchased from your dealer.
