Once trouble is located, repair or replace the part if you are authorized to do so or determine if a higher category of

maintenance is required. Repairs by Organizational Maintenance are limited to tools, test equipment and replacement

parts allocated to that level by the Maintenance Allocation Chart (MAC) located in Appendix B of this manual.

Worn, broken, burned out or disconnected cord or plug.

Wires broken by too much vibration.

Inadequate supply of paper tape, or improper positioning of tape through guides, under type wheel and through

punch and die assembly.
