For information on Seized or Stripped screw extraction see Stripped Screws - Overview. The below information is in addition to the overview article, and is specific to this screw.
If your grabber is bent and when trying to replace it the Flat M3 X 4mm Screw PN: 010133-04 begins stripping, try bending the grabber slightly while trying to remove the screws. Sometimes trying to straighten the grabber can help the screws to come out more easily.
If the situation remains unresolved, you will need additional technical assistance. Here are the available Melco Technical Support options. Check Damaged Grabber if the left or right arms are bent. These arms might need to be replaced.
