tight on the spreading disc.
10. Loosen the spring fastening nut again by around one half turn to guarantee
easy adjustment of the extension vane position.
11. If necessary, repeat the work stages with other spreading vanes which must
be replaced.
Mount both spreading discs again. See 12.8.2:
Mounting the spreading
discs, page 122.
n DANGER
Risk of injury due to rotating machine parts
If the spring fastening nut is too loose, the spreading vane may
become loosened from the spreading disc.
This can lead to damage to the machine and severe injuries.
Only loosen the spring fastening nut so that the spreading
vane position can be adjusted and the flat spring is still tight
against the spreading disc.
