If a screw is loose, remove and replace it.
Always use the new screws provided in the repair kit.
If no new screw is available, add blue threadlocker before reusing the screw.
Do not apply more than the indicated torque.
4. Check the geometry of the part to identify critical deformations.
Place the rigging part on a at surface or hold a level against it.
5. Check the moving parts.
Make sure that the mechanism engages correctly.
