Note:

  The tamper proof ratchet action will not release the tool until it has been fully closed. 

Note

: Whenever crimping without the locator, make sure the seam of the terminal is oriented 

up or down in the tool if using unbrazed product, as this will provide higher pull force values.

OPERATION 

 

Open the tool by first closing the jaws sufficiently for the ratchet 
mechanism to release. 
 

Crimping Terminals 

 

1.  Adjust the locator up or down until the terminal being run sits flat 

and straight in the tool. 

2.  Position the terminal with the barrel facing up into the color-coded 

nest.  Make sure the end of the terminal fits into the locator 
pocket securely and the front edge of the barrel is flush against 
the front edge of the locator, (See Figure 1). 

3.  Partially close the tool to hold the terminal in place (See Figure 

2).

 

4.  Insert the properly stripped wire into the terminal barrel (See Figure 2 and 3).  The wire insulation will stop against the taper of the 

terminal.  Cycle the tool. 
 
 
 

5.  Remove the crimp and inspect for proper crimp location, and check for insulation closure.  Molex offers a Crimp Inspection 

Handbook for closed barrel industrial product.  See our website or contact your sales engineer. 

6.  If the insulation part of the crimp needs to be adjusted, first loosen the M4 screw on the bottom tool jaw, then insert a 3/32 hex 

wrench (supplied) into the bottom of the lower die (See Figure 4).  A clockwise (CW) rotation decreases insulation crimp while a 
counter-clockwise (CCW) rotation increases insulation crimp.  After adjusting retighten the M4 screw.
