With Worn Spare Parts (Wire-Crimper & Anvil; Insulation Crimper & Anvil) the Wire Spare Parts have to be changed by Pairs (Crimper and Anvil Together). The Spare Parts for Insulation Crimp are changed as Necessary. A change of a Total Spare Part Set (Both Crimper & Anvil) for Insulation Crimp is not necessary. (Unless a Combined Anvil is Used, then The Wire Crimper Insulation Crimper and Anvil Should be Replaced). A rework of spare parts is not allowed at All. Used and Worn / Broken Spare Parts Must be Stored in a Red Locked Box, with Access Only by the Maintenance Responsible. Exception: Terminals with weak coating (e.g. Brass) may leave residues in area of the Crimper Surface. It is allowed to remove these residues by polishing the crimper. The special equipment for polishing has to be released by the CC. The Surface of the Crimp Blade Must Not be Scratched or Scored (Only Residual Material Removed).
