The instructions are from Suhr support via email:
We'd like to paste some notes on changing strings on your guitar equipped with Suhr locking tuners and Wilkinson WVS-130 bridge below.
1) De-tune the string until the hole in the tuning post is lined up with the nut slot of the particular string. There will be slack in the string.
2) Loosen the knurled knob on the back of the tuning machine and remove the string from the post. (You can loosen these completely. The knobs won’t fall out)
3) Use the 2mm locking screw wrench to loosen the black locking screw on the top of the saddle. (There’s no need to remove these screws completely and we would advise against doing so, in order to keep the screws from being misplaced)
4) Completely remove the string by pulling it thru the block as you would normally.
5) Go back to the tuning posts and check that the string hole in the post is lined up with the nut slot for the string. We want the string to pass straight thru the post with no wraps.
6) Install the new string by pushing it thru the block as you would normally.
7) Run the string over the top of the appropriate saddle and nut slot and thru the tuning post. The string should be under the edge of the black saddle locking screw when the string is pulled thru the post with tension.
8) While pulling the string thru the center of the tuning post hole, and holding the string in place with tension applied, tighten the knurled knob on the back of the tuner. Don’t over tighten or use a wrench, but apply enough torque so that the string won’t pull out of the post.
9) Tune to pitch
10) There are 4 string "witness" points. The saddle, front of the nut, rear of the nut and tuning post. Starting at the saddle, press each string down gently just before (fretboard side) the saddle/string contact point. Do the same at the front and rear of each nut slot. Also press the string at each tuning post. The idea is to remove any slack in the string at these points of contact and create more crisp break angles in the strings. This, combined with gently stretching new strings by bending them as you would during normal use, should go a long way towards stabilizing the tuning of your guitar.
11) Tighten the black locking screw on the top of the saddle (2mm wrench) Again, apply enough torque to lock the string in place, but there is no need to over tighten.
12) Check tuning one more time (locking the strings down in the last step may pull the string a few cents sharp), re tune if necessary.
