2 / 4 page 408- 7563 Rev B 2 of 4 4. PREPARATION AND CRIMPING Install a reel of terminals on the machine and align a terminal with the dies. Refer to customer manual 409--1993. Crimp only terminals specified for the dies you are using. Refer to Figure 1 to verify the correct wire size and insulation diameter for the product you intend to crimp. 4.1. Insulation Crimp Adjustment 1. With the machine power supply disconnected and the front guard removed, raise the tape release lever and turn the insulation crimp adjustment knob to position No. 4 (loose). Then lower the tape release lever. 2. Insert an unstripped wire into the terminal, and hand cycle the machine one full crimp cycle. 3. Remove the crimped terminal from the machine. Bend the wire 90_ to both sides. If the wire pulls out of the terminal, raise the release lever, turn the adjustment to next lower number, and lower the release lever. Then repeat steps 2 and 3 until the crimp is properly adjusted. The insulation crimp should hold the wire insulation firmly without cutting into it. 4.2. Crimping Procedures Strip the wires to the dimension shown in Figure 1, being careful not to cut or nick the conductor strands. Then, proceed as follows: 1. Insert the stripped end of a wire into the aligned terminal until the wire insulation begins to wedge against the terminal insulation barrel, or until it is against the end of the terminal wire barrel. 2. Hold the wire in place and actuate the machine through a complete cycle. Be sure to allow the crimping dies to open fully before removing the crimped terminal. 4.3. Crimp Inspection (Figure 2) Visually inspect completed crimps, noting the following: — Ends of wire strands must be flush to, or extend beyond, the front of the wire barrel. However, ends may not extend far enough to interfere with insertion of the mating tab. — Wire insulation must be inside the insulation barrel with no conductor showing. Figure 2 Wire Insulation Must be Inside the Insulation Barrel Bellmouth Must be Present at Wire Barrel Terminal May Not be Bent or Twisted Wire Ends Must be Flush to or Beyond End of Wire Barrel — A slight bellmouth must be present in the terminal plastic insulation at the front of the wire barrel. — Terminal may not be bent or twisted in a way that damages the termination or makes mating difficult. For more information on product crimp specifications, refer to application specification 114--1002. 5. MAINTENANCE AND INSPECTION 5.1. Daily Maintenance 1. Remove dust, moisture, and other contaminants with a clean, soft brush, or a clean, soft, lint--free cloth. Do NOT use any objects that could damage the dies or tool. 2. Make sure all die hardware and parts are properly secured. 3. Coat all surfaces with a thin coat of any good SAE 20 motor oil. Do not oil excessively. 4. When the dies are not in use, store them in a clean, dry area. 5.2. Periodic Inspection Regularly scheduled inspections should be conducted and recorded by quality control personnel. It is recommended that the inspection procedures that follow be performed once a month; more often if your work environment, company standards, or amount of tool use indicates the need.
