Worn target rubber skins are picked off target by following steps (general routine):

1. Remove duct tape along edges of the worn target rubber skin.
2. Consider marking the target frame (edges of existing target rubber skin) to easier add a new target rubber skin at later state (getting same tension).
3. Remove staples along edges of the worn target rubber skin (flat screwdriver or staple remover needed, in addition to pliers).
4. Unscrew the hinges of the service panel (screws above the service panel).
5. Pull off service panel (still attached to target rubber skin and hinges). 
6. Turn the service panel back side up, and remove stables along the bottom of the target rubber skin.
7. Unscrew the aluminium bar at the back of the service panel.
8. Keep screws and aluminum bar for later assembly (to be reused).
9. Dispose worn target rubber skin in a proper way.
