Visually inspect bolt assembly (1) for cracks. If bolt assembly is damaged, replace bolt assembly.
Check roller (2) for spring action and freedom of movement. Replace roller if damaged or missing. Replace spring (4) if weak or corroded.
Be sure all pivot points (3) move freely. If pivot points do not move freely, clean and lubricate. If this does not free the pivot points, replace the bolt assembly. Rivets of pivot points must be flush to surface and remain in position.
