TM 1-1500-204-23-6 a. Tool  Calibration  Verification  with  the  Safety Cable Test Fixture or Electronic Pull Tester. NOTE Indenter   calibration   should   be   verified periodically and must always be checked if the nose assembly has been removed or changed. (1) Use  of  the  calibration  test  fixture  and torque    wrench    to    verify    safety    cable    tool   indenter adjustment (see figure 2-100).  Thread the safety cable into the 12 pt.  screw and through the swivel, holding the lever  against  the  built-in-stop.    If  the  lever  is  not  kept against the stop, the results may be adversely affected. Terminate the safety cable with the tool being tested. (2) Apply  approximately  2  lbs  force  to  the cable with your finger at the line marked "test area".  If the  cable  touches  either  the  side  or  bottom  surface  of the  test  fixture,  remove  the  cable  from  the  test  block, and  re-install  another  safety  cable  being  careful  to  set the  tool  tension  properly,  and  to  hold  the  lever  against the stop. (3) Place a calibrated 3/8 inch drive torque wrench (capable of indicating 30 inch/lb.  for 0.020 inch safety cable, 70 inch/lb.  for 0.032 inch safety cable and 110 inch/lb.  for 0.040 inch safety cable) into the square drive hole, orienting the test block and torque wrench on a flat surface.  Do not over torque the cable. SAFETY CABLE DIAMETER INCH TORQUE WRENCH MINIMUM PULL-OFF-LOAD INCH-POUNDS 0.020 30 in/lb 0.032 70 in/lb 0.040 110 in/lb Figure 2-100.  Calibration test Fixture and Torque Wrench (4) The    safety    cable    should    remain    in place  during  application  of  the  measured  force.    Apply approximately 2 lbs.  force to the safety cable with your finger at the line marked "test area".  If the safety cable touches  either  the  side  or  bottom  surface  of  the  test fixture,  the  crimp  is  unacceptable  and  the  tool  indenter should be adjusted. (5) Use of an electronic pull tester to verify safety  cable  tool  indenter  adjustment.    (See  figure  2- 101).    It  may  be  required  in  some  applications  to  pull test  safety  cable  to  destruction.    If  this  is  required,  an electronic   pull   tester   may   be   used   in   place   of   the calibration test fixture/ torque wrench method.  The type of   machine   pictured   in   this   manual   will   satisfy   this requirement. Figure 2-101.  Electronic Safety Cable Pull Tester b. Indenter    Adjustment    for    all    Safety    Cable Application Tool Models. NOTE Calibration should be checked frequently  by  the  use  of  the  calibration test fixture, or the electronic pull tester. (1) Remove the nose assembly by removing  the  two  8-32  socket  head  cap  screws  with  a 9/64 inch hex wrench.  (See figure 2-102). (2) Adjust  the  push-rod  adjustment  screw with   a   flat   blade   screw   driver,   or   the   manufacturer supplied  adjustment  key.    See  figure  7-103.    Turn  the push-rod   adjustment   screw   clockwise   to   loosen   the crimp (enlarge the gaging dimension), or counterclockwise to tighten the crimp (reduce the gaging dimension).  Replace the mose assembly and the two 8- 32  socket  head  cap  screws,  being  sure  that  they  are firmly    tightened.        Check    calibration    as    previously described.
