Result

» Clamping lever (1) is not positioned correctly on the torsion spring.

Measure
- Relax clamping lever (1) carefully and repeat the process.
Clamp mount (1) in vice (2).
Position the clamping lever (3) with the preloaded torsion spring (5) in the mount (1) in the arrow direction.
Snap-in hooks (4) of clamping lever (3) are used to relax clamping lever (3).

Torsion spring (5) is thus relaxed.
