You can carefully place a freshly laundered towel over the face of the mirror as a method of protection should you drop a wrench during the following steps:
11. Carefully rotate the Keepers (Retention Pins) over the face of the mirror.
12. Adjust the nut below the Keepers so that there is a distance of 1/8" (3mm) between the face of the mirror and the bottom of the Keeper.
13. Note that the lower (4 O'clock and 7 O'clock) Retention posts are bored off-center. Rotate the posts leaving a 2mm gap between the Cable Sling and the posts.
None of the posts should be in contact with the mirror or the sling. The posts are used as a safely device should the scope flip over, or the Cable Sling become un-secured.
14. Gently snug the Keeper bolt nuts with a 9/16" wrench (14mm).
15. After the first time collimating the telescope, check to make sure that the mirror face is not in contact with the Keepers.
