figure 1 catht169162011 (straightaction hand tool) was designed to crimp c &69 / (ip % 'series) f r q w d f w s. the front of the tool, is marked with the tool part number, wire size ranges, and crimp height specifications. the tool features a fixed die (crimper), a movable die (anvil), a locator/insulation stop, and a ratchet. many tools feature an insulation adjustment knob which is used to regulate the crimp height of the contact 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 open fully . 3. holding the contact by its mating portion and looking straight into the crimp section, insert the contact from the back of the tool into the appropriate crimp chamber. 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 locator/insulation stop. 7. holding wire in place, crimp contact to the wire by squeezing the tool handles together until the ratchet releases. 8. allow tool handles to open fully and remove the crimped contact from the tool.
figure 2 9. if a terminal becomes jammed in a crimp nest, open the tool jaws using theaemergency ratchet release buttono on the moving handle lever. on many tools, the insulation barrel crimp height is regulated by the insulation adjustment knob (figure 3). the insulation crimp should hold the insulation firmly without cutting into the insulation. to determine the proper insulation crimp setting, test crimp a loose piece contact using the setting which corresponds to the insulation diameter: (1) small; (2) and (3) medium; or (4) large. if the crimped insulation barrel is too tight or loose, change the setting by pulling out and rotating the adjustment knob to the desired setting. figure 3 it is recommended that a maintenance and inspection program be performed periodically to ensure dependable and uniform terminations. frequency of inspection depends on: the care, amount of use, and handling of the hand tool, the presence of abnormal amounts of dust and dirt, your own established standards. the hand tool is inspected before being shipped; however, it is recommended that the tool be inspected immediately upon its arrival at your facility to ensure that the tool has not been damaged during shipment. 1. remove dust, moisture, and other contaminants with a clean brush, or a soft, lintfree cloth. do not use objects that could damage the tool. 2. make certain that the retaining pins are in place and that they are secured with retaining rings. 3. all pins, pivot points, and bearing surfaces should be protected with a thin coat of any good sae 20 oil. 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 characteristics of an application. 1. the hand tool may be immersed (handles partially closed) in a reliable commercial degreasing compound (suitable for plastics) to remove accumulated dirt, grease and foreign matter.
