[.062-in. .002 in.] diameter) into the center contact crimping chamber of the die assembly. 4. close the tool handles completely. 5. securely tighten both screws with the appropriate sc rewdriver. 4. crimping procedure select the appropriate cable size and connector. the wire size and insulation diameter must be within the specified range for the connector. note i this tool is provided with a crimp height adjustment feature. initially, the crimp height should be verified. refer to section 5, crimp height adjustment, to verify crimp height before using the tool. for detailed information on cable strip lengths and pr oper assembly of the connector, refer to the instructions packaged with the connector. make sure that the connector's ferrul e has been placed onto the cable, and that the cable's braided shield is flared away from the cable. then proceed as follows: 4.1. crimping the center contact (figure 2) 1. close the tool handles until the dies are partially closed. 2. assemble the center contact onto the cable cen ter conductor and place the center contact in the smallest crimping chamber of the anvil die. make sure the flange on the end of the center contact butts against the die.

(1) the product specified is correct for the application, ( 2) the specific die assembly is used, (3) the die assembly has been measured to ensure that the openings are correct, and (4) the tool has been adjusted correctly. figure 5 provides information on die opening sizes. 7. replacement these crimping die assemblies are inspected before shipment. it is recommended that the dies be inspected immediatel y upon arrival at your facility to ensure that the dies have not been damaged during shipment. order replacements through your local te r epresentative, 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 8. revision summary revisions to this instruction sheet include: ? changed company name and logo
