408-9938 3 of 5 rev d 6. tighten the nut and close the handles until the ratchet releases. 7. remove and inspect the contact. 8. make another sample crimp. if the contact is straight, tighten the contact support screw. if the contact is still being bent du ring crimping, repeat the adjustment procedure. 5. crimping procedure this tool is provided with a crimp adjustment feature. initially, the crimp height should be verified as specified in figure 4. refer to section 6, crimp height inspection, and section7, ratchet adjustment, to verify crimp height before using the tool to crimp desired contacts and wire sizes. refer to the table in figure 1 and select wire of the specified size and insulation diameter. strip the wire to the length indicated in figure 1, taking care not to nick or cut wire strands. select an applicable contact and identify the appropriate crimp section according to the wire size markings on the tool. refer to figure 3 and proceed as follows: 1. hold the tool so that the back (wire side) is facing you. squeeze tool handles together and allow them to open fully. 2. holding the contact by t he mating end, insert the contact ? insulation barrel first ? through the front of the tool and into the appropriate crimp section. 3. position the contact so that the mating end of the contact is on the locator side of the tool, and so that the open ?u? of the wire and insulation barrels face the top of the tool. place th e contact up into the nest so that the movable locator drops into the slot in the contact. refer to figure 3. butt the front end of the wire barrel against the movable locator. make sure that both sides of the insulation barrel are started evenly into the crimping section. do not attempt to crimp an improperly positioned contact. 4. hold the contact in position and squeeze the tool handles together until ratche t engages sufficiently to hold the contact in position. do not deform insulation barrel or wire barrel. 5. insert stripped wire into contact insulation and wire barrels until it is butted against the wire stop, as shown in figure 3. 6. holding the wire in place, squeeze tool handles together until ratchet releases. allow tool handles to open and remove crimped contact. the crimped contact may sti ck in the crimping area, but the contact can be easily removed by pushing downward on the top of the locator (see figure 3). 7. check the contact?s crimp height as described in section 6, crimp height inspection. if necessary, adjust the crimp height as described in section 7, ratchet (crimp height) adjustment. figure 3 note i caution ! note i adjustment screw for contact support contact support locator back of tool (wire side) wire locator in wire stop contact (typ) strip length wire inserted to stop
408-9938 4 of 5 rev d 6. crimp height inspection crimp height inspection is performed through the use of a micrometer with a modified anvil, commonly referred to as a crimp-height comparator. te does not manufacture or market crimp-height comparators. detailed information on ob taining and using crimp- height comparators can be found in instruction sheet 408-7424. proceed as follows: 1. refer to figure 4 and select a wire (maximum size) for each crimp section listed. 2. refer to se ction 5, crimping procedure, and crimp the contact(s) accordingly. figure 4 3. using a crimp height comparator, measure the wire barrel crimp height as shown in figure 4. if the crimp height conforms to that shown in the table, the tool is considered dimensionally correct. if not, the tool must be adjusted. refer to section 7, ratchet (crimp height) adjustment. 7. ratchet (crimp height) adjustment (figure 5) 1. remove the lockscrew from the ratchet adjustment wheel. 2. using a screwdriver, adjust the ratchet wheel from the locator side of the tool. 3. observe the ratchet adjustment wheel. if a tighter crimp is required, rotate the adjustment wheel counterclockwise to a higher-numbered setting. if a looser crimp is required, rotate the adjustment wheel clockwise to a lower-numbered setting. 4. replace the lockscrew. 5. make a sample crimp and measure the crimp height. if the dimension is acceptable, replace and secure the lockscrew. if the dimension is unacceptable, continue to adjust the ratchet, and again measure a sample crimp. figure 5 8. maintenance ensure that the tool fram e and dies are clean by wiping them with a clean, soft cloth. remove any debris with a clean, soft brus h. do not use objects that could damage the tool. when not in use, keep tool handles closed to prevent objects from becoming lodged in the dies, and store in a clean, dry area. 9. visual inspection the crimping dies should be inspected on a regular basis to ensure that they have not become worn or damaged. inspect the crimp sections for flattened, chipped, worn, or broken areas. if damage or abnormal wear is evident, t he tool must be replaced. see section 10, replacement. 10. replacement customer-replaceable parts are shown in figure 1. available separately, pro-crimper iii hand crimping tool repair kit 679221-1 includes a replacement nut and a variety of pins, rings, screws, and springs. if the dies are damaged or worn excessively, they must be replaced. order the repair kit and replaceable parts through your te representative, or call 1-800-526-5142, or send a facsimile of your purchase order to 1-717-986-7605, or write to: customer service (038-035) tyco electronics corporation po box 3608 harrisburg pa 17105-3608 11. revision summary revisions to this instruction sheet include: ? updated document to corporate requirements ? corrected tooling inform ation in section 1, introduction wire size awg (max) crimp section (wire size marking) crimp height dimension ?a?
