12.8.1 Replacing the spreading vanes
WARNING
Danger of ejection of spreading vanes caused by the uninten-
tional release of fixing bolts and quick-release screw connec-
tions!
• When replacing the spreading vanes, it is essential to replace
used self-locking nuts of the fixing bolts with new ones. A used
self-locking nut no longer has the required clamping force to
produce a secure screw connection.
• Ensure that the open side of the disc spring is toward the
spreading disc before tightening the wing nut. Only in this posi-
tion can the disc spring pretension and secure the quick-release
screw connection.
It is essential to ensure that the spreading vanes are installed correct-
ly! The open side of the U-shaped spreading vane must be facing the
direction of rotation.
When exchanging the spreading vanes and swivel blades, use the
assembly paste provided. This is the only way to ensure that the
specified tightening torque is sufficient.
