## Breakage Shear Blades

- In particular cases shear blades may break through. This occurs rarely and is usually caused by incorrect mounting of the shear blades.
- The following reasons may cause breakage of shear blades : 
    - The contact area is not flat
    - The contact area is dirty
    - Mechanical stresses caused by installation
    - Mechanical overload
