insulation barrel during the crimping operation. The locator/insulation stop positions the contact, and limits the insertion distance of the stripped wire into the contact. In use, the locator/insulation stop rests in the locator slot of the contact (See Figures 1 and 2). The ratchet assures full crimping of the contact. Once engaged, the ratchet will not release until the dies have been fully closed. Refer to Figure 2 for wire preparation information before applying the terminal. 1. Hold the tool so that the front side is facing you. 2. Ensure that the tool ratchet is released by squeezing the tool handles and allowing them to Figure 1 open fully. 3. Holding the contact by its mating portion and looking straight into the crimp section, insert the Straight Action Hand Tool CATHT179202411 contact from the back of the tool into the (Figure 1) was designed to crimp CC79L appropriate crimp chamber. (IPD1Series) contacts. 4. Position the contact between the crimpers so that the locator/insulation stop enters the slot in the contact. The wire barrel should butt against the locator/insulation stop. Refer to Figure 1. 5. Holding the contact in this position, squeeze the tool handles together until the insulation anvil starts entry into the insulation crimper (usually two ratchet clicks). Do not deform the insulation barrel or wire barrel. 6. Insert a properly stripped wire through the locator slot and into the wire barrel of the contact until the insulation butts against the The front of the tool, is marked with the tool part locator/insulation stop. number, wire size ranges, and crimp height 7.

On many tools, the insulation barrel crimp height is regulated by the insulation adjustment knob (Figure 3). The insulation crimp should hold the 1.

Do not oil excessively. 4. When the tool is not in use, keep handles closed to prevent objects from becoming lodged in the crimping jaws. 5. Store the tool in a clean, dry area. Lubricate all pins, pivot points, and bearing surfaces with SAE 20 oil as follows: Tools used in daily production lubricate daily Tools used daily (occasional) lubricate weekly Tools used weekly lubricate monthly Wipe excess oil from tool, particularly from crimping area. Oil transferred from the crimping area onto certain terminations may affect the electrical Figure 3 characteristics of an application. 1.
