TM 1-1500-204-23-6 f. Safety Cable Identification Stamp. In applications where the user requires a logo or ID code to be a permanent part of the safety cable installation (for warranty or tractability), it shall be applied by the safety cable   manufacturer   to   one   or   more   surfaces   of   the square end fitting of the safety cable.  Only impression stamping    is    permitted,    no    paint,    ink    or    labels    are acceptable.  See figure 2-91. Figure 2-91.  Safety Cable Identification Stamp. g. Safety Cable on Turnbuckles.  The standard procedure  for  securing  turnbuckles  with  safety  cable  is shown in figures 2-92 and 2-93. (1) A  self  looping  safety  cable  is  threaded through  the  turnbuckle.    One  end  shall  be  wrapped  in one direction around the turnbuckle.  The safety cable is then   threaded   through   the   hole   in   the   self   looping jumper, and terminated with the appropriate application tool. (2) Safety    cable    diameter    selection    for turnbuckle    applications,    0.032    inch    diameter    safety cable shall be used on assemblies where cable diameter is  1/16  inch  or  smaller,  and  0.040  inch  diameter  safety cable   or   greater   shall   be   used   on   turnbuckle   cable diameters greater than 1/16 inch. Figure 2-92.  Routing of Safety Cable on Turnbuckles Figure 2-93.  Example of Final Safety Cable Turnbuckle Installation h. Safety Cable Jacketing for Protection.    (See figure 2-94).  It is recommended to use a tubular jacket over safety cable when it is installed in a location where it is in contact with (or may contact) surfaces which may damage the safety cable.  A tubular jacket material shall be  capable  of  meeting  the  temperature  range  of  the application, it shall be resistant to oil and chemicals.

Procedures.  When safety cable is used, the following   basics   apply   for   the   application   tools   and calibration equipment. (1) Minimize   mixing   of   safety   wire   and safety cable. (2) Install the ferrule cartridge into the tool body under the handle grip. NOTE When    loading    and    using    the    safety cable   hand   tool,   be   certain   that   the correct   size   safety   cable   kit   is   being used with the tool. (3) Install   the   safety   cable   through   the fasteners to be secured. (4) The nose can index to four positions at 90° increments.  To select the position, push the nose in towards   the   tool   and   rotate   to   the   desired   position. Release  the  nose,  if  the  nose  does  not  lock  into  the indexed position, turn it slightly until it does.  See figure 2-95. (5) Insert the free end of the cable through the  ferrule  in  the  cartridge,  and  remove  the  ferrule  by pulling  the  cable  away  from  the  end  of  the  cartridge. See figure 2-95.
