Always tighten screws (A) that are attached to the frame
(B) before attaching a locknut (C) on the opposite side.
Do not tighten the locknut (C) with too high a torque. If
you tighten the locknut with too high a torque, the
tension of the screw in the frame decreases. The screw
will then come loose during operation.
