If there is looseness, follow the procedure described below to place the enclosed pad between the clamping pad of the thumb screw and the mounting surface.
 

1. Position the mounting bracket onto the mounting surface (worktable, desk, etc.).
   Place the pad between the clamping pad of the thumb screw and the mounting surface (worktable, desk, etc.), and then firmly tighten the thumb screw.

2. Check that there is no looseness. If the mounting jig is still loose, remove it, and then install it again.
   • Be sure that the mounting bracket is securely clamped onto the mounting surface and that the thumb screw is firmly tightened.
   • Do not attach the mounting jig to an unstable surface (flexible, bent or warped).
   • Be careful that the mounting jig does not fall when it is removed.
