We also installed the 4 special interface plates in the left bottom part, so we could install mirrors at those points. There was one accident. When the CaSana people were installing the mirror in (2, -8), they found a crack on the surface of the mirror in (0,-8). Probably they made it, because they had tried to get their cherry picker closer to the mirror many times. The size of crack is about 1cm×4cm from their pictures and movies. We asked Uwe to put silicone on the surface of the cracked mirror as a temporal solution and they did. Probably we will replace that mirror to new one at Mirca as soon as possible.<br>|| |

Trouble Shooting
- 2018/04/28
- While inserting a safety bolt, we damaged a little the edge of the hole. We kept this mirror today and will attach silicon paint the next working day.
- We found one fixed point which has one hole just above a sticking part of the hose band. We replaced with a new fixed point as we could not insert a bolt to that hole.
- 2018/04/26
- When Casana people tried to install one mirror, they realized a big nut did not fit the fixed point and they could not fix the fixed point. It may have happened in the dish when trying to fix the nut. We solved this problem quickly by replacing the fixed point with a new one. Still, we check if a nut fits well a fixed point of a mirror to be installed before attaching it to the cherry picker.
- Sometimes it is very hard to insert safety bolts because of glue and a tape inside the hole. We solved by using a small hammer and a small screwdriver which Holger suggested to us to use to remove glue or tape.
