• Check the cover band after every 2000 km of operating distance.
Waves on the cover band are a sign for wear of the band reverser.
• In case of wave formation, tighten the cover band as follows:
1. Loosen screws aB (è Fig. 9).
2. Push the cover band into the end cover.
3. Retighten the screws with 2 Nm.
If the cover band can no longer be retightened, the level of wear of the band reversers is too great
