4 / 5 page 408-4074 4 of 5 Rev B 6.2. Periodic Maintenance Regular inspections should be performed by your quality control personnel with a record of these control inspections remaining with the personnel responsible for the tool. TE recommends one inspection a month; however, operator training and skill, amount of use, ambient working conditions, and your company's established standards are all factors in establishing frequency of inspections. These inspections should be performed in the following sequence: 1. Remove any accumulated film with a suitable cleaning agent that will NOT affect plastic material. 2. Make sure all components are in place and properly secured. See Figure 7. 3. Make a few test terminations and inspect the terminations in accordance with Section 5, INSPECTION. 4. Check for chipped, cracked, worn, or broken areas. If damage is evident, repair if necessary. See Section 7, REPLACEMENT AND REPAIR. 6.3. Occasional Maintenance Because this tool shears wires before insertion, wear of the shearing surfaces can be expected as a normal operating condition. Since wire size, insulation diameter and hardness are all variables, a reasonable life expectancy of the shearing edges cannot be determined. Shearing occurs along the edge where the inserter rides against the shear. When the operator of the tool starts to notice wire ends that are not cleanly cut, or if excessive force becomes necessary to shear the wires, it is time to change or replace the two components that do the shearing. Refer to Figure 6 and proceed as follows: 1. To change the position of the shear, remove the cover of the terminating head by loosening the two 4-40 socket head cap screws which hold the head in place. Carefully, lift off the cover. See Figure 6. NOTE i DO NOT lift the inserter off with the cover. 2. Lift off the inserter. (Make note as to which side is in contact with the shear.) 3. Lift off the shear. Rotate the shear 180° so that the surface that was facing down is now facing up. Place the shear back in place. 4. Replace the inserter, making sure that the surface (that was in contact with the shear when disassembling the tool) is now rotated 180° away from the shear.

Replace the cover. Align the edges of the terminating head, shear, and cover and tighten the two 4-40 socket head cap screws. NOTE i This procedure can only be done one time for each set of inserter and shear. When the second shearing edge becomes dull, replacement of the inserter and shear will be necessary. CAUTION ! Attempts to sharpen the inserter or shear might cause the inserter to be out of position during wire insertion and cause damage to the connector or tool. |
