Removing
unscrew the screw (1), insert a plastic or wooden spatula (2), release the clamps (3), then release the tabs.
Note: Insert the spatula in close proximity to the clamp or lip. Do not damage adjacent parts.
Installation
Replace 2 bushings at the bottom (pay attention to the correct installation).
Align the tabs with the bushings and secure them.
Note: First align and secure the tab with sleeve 1, then with sleeve 2. Or, align both tab-sleeve pairs at once.
Caution: Do not try to align the tab with bushing 2 first, then with bushing 1.
