During operation today, it was observed that the main vault door had issues opening.. typically when the door was around 80-90% opened, it would stop

issue was consistent and observed multiple times when trays 2, 5, and 6 were engaged (note these are all on the same side of the vault). It was overcome |

Pumped down again on Dec. 12 2023. Was taking a long time so might not be as good as earlier. Maybe there is a leak in there... |
