Assembly instructions: Assembly is quite simple, but the sequence is very important

1. Start with the lock cilinder. And fill the holes with the pins 1 to 5. 1 is furhters away from the gear. 5 is closest to the gear. The pointy side schould be down, the slightly rounded side should be up. The pins should move without to much resistance.
2. To check if the pins are inserted correctly, carefully slide in the key. The pins should lay flush with the cilinder. Remove the key.
3. Slide the cilinder in the cilinder housing. The holes alligned.
4. Place the lock pins in the holes of the cilinder housing. The pins should move without to much resistance.

6. Place the small spring (P09) over the shaft.
7. Lock in place with the c-ring
