(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. 5.3. ratchet adjustment the tool frame assembly ratchet mechanism features an adjustment wheel with eight settings. the adjustment wheel controls the amount of handle pressure exerted on the tool jaws and crimping dies during crimping. if the crimp is not acceptable, adjust the ratchet as follows: 1. sufficiently loosen the screw at the ratchet ad justment wheel so that the wheel can be rotated above the post that engages the teeth in the wheel. 2. if the crimp is too loose, turn the wheel to a h igher notch (for example, if the wheel is set at notch no. 5, move the whee l to notch no. 6). if the crimp is too tight, move the wheel to a lower notch. 3. tighten the screw at the ratchet adjustment wheel. if the crimp cannot be made to conform to the d imensions provided in the appropriate product application specification, the tool and/or dies are defective and must be replaced. note i other dies of the pro-crimper hand tool series may be used in this tool; however, the ratchet adjustment wheel may require adjustment to achie ve acceptable crimp height. 6. parts replacement customer-replaceable parts are shown in figure 1. available separately, epair kit 679221-1 includes 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 7. revision summary revisions to this instruction sheet include: ? changed company name and logo
