3.2.6 PROCEDURE FOR REMOVING THE SECONDARY MIRROR FROM THE SUPPORT
1. Wear a dust mask and powder-free latex gloves. Remove any jewelry and items from
pockets that may fall onto the mirror surface.
2. If desired, apply a protective coating to the optical surface of the mirror and allow it to dry
according to the manufacturers recommendations. Applying multiple coats may simplify the
removal process.
3. Place the M2 Assembly securely on blocks, leaving enough room to work under the support.
4. Remove the steel wire connected to the three safety pucks (COM-5974).
5. Move the blocks inside the diameter of the M2 Baffle Holder and verify that M2 Assembly is
secure.
6. Note existing marks or mark the orientation of the M2 Mirror on the M2 Attachment Plate.
7. Remove the six M8 SHCS securing each half of the M2 Baffle Holder (COM-10239) to the
M2 Attachment Plate (COM-5188) and carefully remove the baffle holder, see Figure 3.
