2 / 4 page 408- 4303 Pneumatic CERTI- CRIMP Tool Holder Assemblies 356302- 1, 356303- 1, and 1673611- 1 Rev F 2 of 4 Tyco Electronics Corporation on the bottom of the tool holder. Tighten locking ring to fully secure the tool holder. When tool holder is properly installed, the tool holder locking ring should be butted against the stop ring, and threads of the tool holder should not be visible. If not properly installed, check that correct assembly of cam and tool holder is being used and that they are aligned properly. 6. Rotate the tool holder one full turn in each direction and note that the tool holder locking ring rotates with the holder. To avoid personal injury, periodically check that tool holder locking ring is tightly securing the tool holder. After installation, ALWAYS ensure that the tool holder pivot pins are fully tightened to avoid personal injury or damage to the tool. Removal is the reverse of installation. 7. For instructions on installing the crimping head (and, if applicable, die set), refer to the instruction sheet packaged with the head. 4. CRIMP HEIGHT ADJUSTMENT The tool holder assembly features an adjustable eccentric and a ratchet mechanism with a range of settings. The position of the pawl ensures that the tool completes the cycle. The eccentric controls the amount of cam pressure exerted on the crimping head jaws or dies during the crimping procedure. Although the ratchet is preset prior to shipment, it is important that the crimp height be verified. Also, general use and subsequent wear may cause the tool to go out of adjustment. It is recommended that the crimp height be inspected, and adjusted if necessary, on a regular basis by quality control personnel. 1. Connect pneumatic tool to an adequate air supply between 620 to 690 kPa [90 to100 psi]. For specific information on air line requirements and air hose installation, refer to the instructions packaged with the pneumatic tooling assembly. 2. Place a contact on the crimp nest and place a properly prepared wire of the correct size into the wire barrel. 3. Place a 0.025--mm [.001--in.] shim between the crimping jaws where the jaws bottom against each other. 4. Slowly crimp the contact onto the wire until the crimping jaws or dies bottom on the shim. Check that the ratchet releases after the jaws or dies bottom. To avoid personal injury, DISCONNECT TOOL FROM AIR SUPPLY before adjusting the pawl position. After the adjustment, ALWAYS ensure that the tool holder pivot pins are fully tightened to avoid personal injury or damage to the tool. 5. If the ratchet releases before the jaws or dies bottom, loosen the three securing screws (see Figure 1), remove the eccentric adjustment screw and rotate the eccentric clockwise to a higher setting. Repeat as required. If the ratchet does not release and the tool will not return, slowly actuate the tool until the force of the cam teeth is off the pawl, then push on the pawl with a small screwdriver until the pawl is released from the teeth, release the tool handle and allow the tool to return.
