If on a roll, do not cut the stems, leave them until the wire is crimped. Prepare the wire by stripping approximately 1/8" (3 mm) of insulation from the end. Place the wire into the crimp pin, aligning so that the stripped portion is between the inner set of tabs on the crimp rod, while the insulated wire is between the outer set of tabs . 2.In your crimp pins are too short for this method.see the bottom of these instructions for an alternative. Place the wire and crimp pin on the appropriate tooth of the tool die, making sure the insulated end is on the raised, wider half of the tooth. Tabs should point towards the cavity on the other side of the die so that the tool bends them inward around the wire as it closes. 3.Slowly and fully close the jaws of the tool until they release. The tabs on a properly crimped pin should form a barrel around the lead wires and another strain relief cylinder around the
